In their recent MozCon 2024 conference, Moz's spokesperson said that the ''search landscape has seen more turbulence this last year than in their whole history". And we agree. It's due to these changes that the usage of AI SEO tools for keyword research has increased to a great extent.
But before getting into AI keyword research tools, advanced SEO marketers should ask themselves a few questions.
How well will this tool grow with you? You want the tool to scale with you and your SEO goals. There's no point in investing in a tool that will become obsolete as your business grows.
Can the tool identify opportunities where your competitors are ranking but you're not? Simply put, it should be able to conduct gap analysis for everything from keywords and content to backlinks.
Does the tool integrate seamlessly with your current stack? It's extremely important that your AI keyword tool for SEO research integrates with your existing SEO workflow so that you can make the most out of it.
Does the AI tool grasp search intent? When we say the future of SEO is intent-driven, we mean it. The underlying intent behind a search query carries immense power. If the AI tool cannot identify and understand intent, it may lead you astray.
Does the tool have additional features to complement your SEO strategy? SEO doesn't work in a silo. It's integrated with marketing and advertising. It's best if your chosen tool has market research, content, advertising, and basic social media features.
Keep these questions in mind as you find the best AI keyword tool for SEO research from our guide below.

How AI Technology is Changing Keyword Research
The advent of AI has brought significant changes to how we conduct keyword research. For one, it has sped up the process immensely. AI can scour through millions of data points and provide insights in a matter of seconds, something that would have taken days for a human to do.
And this is not merely an observation but a fact. Our AI Marketing Benchmark Report found that 70.6% of marketers believe AI has the ability to outperform humans in marketing tasks. This is why almost 20% of our survey respondents have allocated over 40% of their marketing budget to AI-assisted campaigns.
When it comes to the actual outcome of using AI in marketing operations, there have been more positive experiences than negative ones. Over 34% of marketers told us that they have seen positive outcomes from AI use, compared to 17.5% who have had to deal with negative outcomes.
Some of the positive outcomes that AI can bring in keyword research are more accuracy, intent-based keyword suggestions, and the ability to track trends and changes in search behavior. However, that's not to say humans can step away completely from keyword research. Just as our report found, over 32% of respondents believe that high-level strategy will remain a human domain.
Based on this, we'd say that AI has streamlined keyword research and not completely taken over it. Since advanced SEO is all about high-level strategies, human input is a non-negotiable part of the process.
Best AI Keyword Tools for Advanced SEO Research
Semrush is among the best SEO tools in the market, comparable to other top contenders like Moz and Ahrefs. However, where the tool shines in its AI adoption and scalability, which has advanced much quicker than the other two top players. What started as a keyword research tool has evolved to include a comprehensive suite of features, including but not limited to on-page SEO, competitor analysis, content marketing, local SEO, social media management, link building, and market analysis. Semrush has introduced AI features in all these tools, primarily in keyword research, content marketing, and market analysis. Semrush reportedly uses its own machine-learning algorithms to provide keyword data. As for keyword analytics and search engine rankings, the tool uses third-party data providers to gather actual search result pages from Google for millions of keywords. It also collects information for the top 100 ranking websites. Besides organic search results, Semrush also collects paid search result data to provide the complete picture. To date, Semrush has gathered data for 26.1 billion keywords across 142 geographical databases and 808 million domains. These figures are much higher compared to the tool’s competitors, indicating its wide-ranging data collection capabilities. Semrush isn’t only more extensive in terms of data, but it is also more accurate. In a self-conducted study, the tool found that over 32% of its keyword search volume results were the closest to those of Google Search Console values, which was highest among competitors like Moz, Ahrefs, and Serpstat. Another interesting thing about Semrush is that it’s ideal for international and local SEO, too. For the former, the tool has a large repository of keywords in each country. For example, just for Brazil, Semrush has 2.5 billion keywords in its database. As for local SEO, Semrush can list your business for 150+ directories to give you the maximum exposure. Semrush also has an impressive backlink database, boasting 43 trillion links. While this isn’t as extensive as Ahrefs’ database, it’s still a significant amount of backlink data that can provide valuable insights for SEO strategies. The best part about Semrush’s data is that it is updated every day, with some metrics like keyword position tracking getting updated every 24 to 48 hours. So, whatever you see in the dashboard is always the most recent and accurate data available. Semrush has long been an SEO expert favorite, and these features are why. TheKeyword Magic Tool provides you with keyword insights from a database of over 26 billion keywords. It uses AI to provide 20 million ideas for a single keyword, including keyword groups, topic clusters, and keyword strategies. Plus, it can expand your keyword lists to show less competitive long-tail phrases that have a high click-through potential. Semrush has introduced new AI features to its Keyword Magic Tool, too: Semrush’s Position Tracking tool helps keep track of your website’s position for specific keywords on different devices and locations. It also shows you the top features that are present in each SERP, including the newly introduced AI Overviews on Google. Since Semrush updates this data regularly, you can stay ahead of algorithm changes and the position shifts resulting from them. Semrush’sWriting Assistant provides AI-driven content recommendations that can help optimize your website’s content. It analyzes your written copy and compares it to the top 10 results for a given keyword, providing you with suggestions on how to improve your content’s SEO and readability. As you can see from the example below, it doesn’t merely focus on keywords for SEO. It also provides suggestions, such as adding links and images to make your content more authoritative. Semrush leverages AI to conduct traffic analytics and audit your competitors’ websites. It also shows you opportunities to outcompete them based on your website’s strengths and weaknesses. Even better, Semrush’s AI provides deep knowledge of your competitors’ ads to help you understand their strategy and improve your own. Semrush has helped SEO experts and marketers in pretty much every industry, but to show how the tool even provided keyword insights for niche topics, we picked Hepper’s case study. The pet furniture company wanted to publish 5,000 posts in 24 months to grow their organic traffic to 1 million page views a month. They used the Keyword Magic Tool to find relevant keywords for content creation. Then, they found the keywords their competitors rank for by using the Organic Research tool. After posting content regularly, they used Semrush Domain Overview to monitor their domain’s authority. The strategy turned out to be a success, with 90,000 daily organic page views and a 2,964% increase in product sales revenue. There’s no denying that Semrush’s AI capabilities are ultra-impressive, but the tool can be hard to navigate for beginners. Its advanced features can be overwhelming, and some users may find the interface too complicated. Plus, it’s also a tad bit expensive for small businesses and startups. Ahrefs is another well-known SEO tool that offers a wide range of features to help businesses grow their online presence. It’s known for its backlink analysis, site audit, keyword research, and content explorer tools. Recently, the tool has introduced a ton of AI features such as AI suggestions, translation, search intent, and content creation. Ahrefs database contains over 28.7 billion keywords, with 2 billion in the US alone. Just like Semrush, international SEO won’t be an issue with Ahrefs since the tool provides keyword suggestions in 217 locations. As we mentioned above, Ahrefs’ backlink database is also the best in the world, as their web crawler is second-most-active behind Google’s and is updated every 15 minutes. The tool’s keyword search volume and CPC are updated every few weeks or once a month, while the rank tracker data is updated weekly. While it’s not as frequent as Semrush, it does the job. While Ahrefs has site audit and backlink features, we’ll focus on its keyword research aspect for this review. Ahrefs’ Keyword Explorer comes with built-in AI suggestions to start your keyword research. The Ask AI search bar provides you with presets that you can use to search for keywords with different modifiers. Good news: this feature also works with languages other than English. The tool also uses AI to analyze search intent for each keyword. You can use this information to shape your content strategy and create more targeted, high-converting content. Ahrefs’ SERP AI doesn’t only show you the search intent but also the percentage of traffic going to each user intent. So you can select your content angle accordingly. Once you write content based on Ahrefs’ keyword suggestions, you can then use the tool’s AI Content Grader to analyze your content based on the top-ranking pages. It also provides suggestions to improve your content’s SEO score. Even before you get to this step, you can use Ahrefs’ AI writing tools to create content outlines or topic ideas based on the top-performing pages for a particular keyword. Another plus for international SEO is Ahrefs’ AI translation feature, which lets you find keywords in a particular language rather than first finding them in English and then translating them. Since words have different nuances and uses in different languages, the AI keyword tool shows you the most popular context variation for every keyword. Currently, Ahrefs supports 40+ languages spoken across 180+ countries. 180 Marketing, an eCommerce business, started using Ahrefs because paying for multiple tools to get comprehensive SEO features proved to be expensive for them. After getting Ahrefs, they started using the Keywords Explorer tool to conduct keyword research for their website. They also used the Site Audit feature to fix technical issues on their website. Ahrefs’ SERP comparison feature also helped the business understand how search intent changed for keywords over time, especially after Google updates. 180 Marketing could use this information to optimize its content and ranking for long-term success. That’s exactly what happened. 180 Marketing was able to cut down SEO tool costs by 70% while seeing a 350% increase in organic search traffic and revenue. When compared to Semrush, Ahrefs doesn’t have as many tools. Also, Ahrefs’ data doesn’t update as frequently, so it might not be the best tool for monitoring daily changes in your rankings or keyword positions and search volumes. Also, Ahrefs’ keyword suggestions can be irrelevant at times. They don’t provide you with clusters or groupings of related keywords. So, you might have to use other tools like SEMrush or Google Keyword Planner for that. Moz is the third SEO tool in the holy trinity of SEO. Its SEO suite isn’t as comprehensive as Semrush or Ahrefs, but it has its own unique features that make it a worthy competitor. In response to a community forum question, Moz responded that their Pro data comes from their own database and a third party, Similarweb. For the Keyword Explorer, they also get information from its database of millions of keywords. Moz’s database is smaller than the other two competitors, including 1.25 billion keyword suggestions. Just like Ahrefs, Moz collects new keyword data on a monthly basis. Moz’s Keyword Explorer is just like any other keyword research tool, but it has some additional AI features. Moz has introduced advanced natural language processing (NLP) in their keyword research tool to identify and suggest search intents to the user. Their search intent model is based on a two-layer process: a machine learning model trained to understand user intent and a rule-based model that shows results based on years of research and expertise about Google SERP. Moz’s Domain Overview tool has two AI features: The Keyword Explorer uses AI to show the following scores: keyword difficulty, volume, and expected organic click-through rates. These scores help you predict how well a particular keyword will perform for your website. Tinuiti, a digital marketing agency, uses Moz as its AI marketing tool of choice to serve its clients. They use Moz’s Keyword Explorer to find keywords for their clients. Moz also allows them to track campaigns over time, including multiple data points, such as domain authority, crawling, and rankings. They can also use Moz Local to improve their clients’ local search presence. Meanwhile, the STAT Search Analytics feature offers them deep SERP analytics. According to Tony Edward, the SEO Director at the agency, “Moz’s all-in-one toolkit has been the backbone of our services for a long time. We set it up on day one, and we continue to rely on its insight to have stability in our service as we help our clients grow their brands and succeed in search.“ Moz’s uses have resulted in a 44% increase in year-over-year organic traffic growth for the agency’s clients. Moz isn’t as comprehensive as Ahrefs or Semrush. Not only does it have fewer keyword research features, but it also has a smaller database. Its AI features are also limited compared to Ahrefs and Semrush. Unlike Semrush, where you cannot only find keywords but also use AI-built strategies, Moz only displays keyword suggestions with predicted metrics. SE Ranking is an SEO tool with features similar to those of the tools mentioned above, although its functionality is not as advanced. The tool uses an AI-based formula to measure organic traffic for keywords. Its machine-learning methods also analyze SERP features, search intent, and keyword position fluctuations. The tool also has AI-powered insights for local businesses. They can use these local SEO-focused insights to target customers in a particular area. Additionally, SE Ranking offers keyword suggestions and content optimization recommendations to improve website rankings on search engines. In the wake of Google introducing AI Overviews, SE Ranking has also created an AI Overviews Tracker, which analyzes AI snippets for your keywords and provides search intent behind the keywords used in this SERP element. Hailing itself as an AI-powered SEO and content marketing platform, Scalenut has basic keyword research features that you might find in other tools, too. However, it’s the tool’s AI-powered keyword cluster reporting that sets it apart from competitors. Scalenut uses AI to create clusters of relevant keywords and phrases that are related to your primary keyword. You can then find secondary keywords for your content within this cluster. The tool also creates a multiple-keyword SEO report based on your selected clusters. The built-in AI content writing tool lets you import your keyword clusters and create content using platform-given insights. As a result, the whole content creation process becomes a breeze. NeuralText is another AI keyword clustering tool that optimizes your content strategy by clustering millions of keywords in minutes. For each keyword cluster, you can see the total impressions and search volume for the cluster as a whole and its individual keywords. NeuralText’s underlying AI algorithm forms these clusters based on search intent so you can easily identify and target the right keywords for your content. The tool also provides a Live SERP analysis to give you a better understanding of your keyword’s competition and ranking potential. Additionally, NeuralText offers an AI content writer that uses its keyword clusters to generate high-quality content ideas for your website or blog posts.1. SEMrush

Is Keyword Research Still Relevant in Today's SEO Landscape?
The short answer is Yes.
Keyword research will be relevant as long as search engines exist.
However, the way we approach keyword research has changed due to changes in search engine algorithms. For example, Google has now introduced AI Overviews, which appear as AI snippets above the organic SERPs. So, your keyword research has to be more holistic and smarter to rank in those snippets.
AI Overviews are going to dominate Google.
Your SEO needs to include AIO (AI Optimisation).
Google is rolling out AI Overviews as we speak, replacing featured snippets and taking up prime real estate.
Here's how to optimise for AI Overviews: pic.twitter.com/YZ16Q0bTf7
— Jake Ward (@jakezward) September 18, 2024
Since Google is now integrating ads into AI Overviews, it’s obvious that the snippet is not going away. In fact, it will only become more prevalent in the future. That's why many of the tools we've reviewed above now have AI Overview tracking features.
Besides Google's changing algorithm, user intents also impact the necessity of keyword research. People are now using voice search more frequently, and it often involves natural language queries rather than specific keywords. This means that keyword research needs to account for not only individual keywords but also long-tail phrases and variations.
However, this is not to say that keyword research is all that SEO is. It's just one part of the larger machinery that gets you to rank higher on Google. Combine keyword research with broader SEO strategies like content marketing, link building, topic mapping, and technical optimization to get the best results.
Why Use AI for Keyword Research
Around 42% of enterprises use AI in their business operations, and the most common use of AI is in marketing and advertising. So, it makes sense for you to use AI in keyword research. Here are some reasons to convince you.
AI's Ability to Predict Emerging Trends and Search Behavior
Human-powered keyword research is based on past data, which may not necessarily reflect current or future trends. But, AI can provide a comprehensive view of past, present, and future data.
So, AI is able to identify and predict future trends to quite some extent. With the consistent use of AI keyword research tools, you can stay informed of emerging search trends before they become mainstream. Besides seasonal trends, AI can also predict consumer behavior changes and search patterns that may impact your business.
Enhanced Understanding of User Intent and Context
As we've discussed in the reviews. AI keyword research tools like Semrush and Moz focus heavily on user intent analysis. AI algorithms use NLP to decipher the context of a search query and understand what users are looking for. They not only look at the keywords but also analyze the situational and behavioral factors that impact a user's search intent.
Some AI keyword research tools, such as NeuralText and Scalenut, further put keywords into clusters based on the user intent. This way, you have a reservoir of keywords for your content strategy.
Data-Driven Topic Clustering and Semantic Keyword Suggestions
Speaking of keyword clustering, AI keyword research tools offer highly accurate semantic keyword suggestions. These tools analyze millions of content pieces on your niche and provide you with clusters of topically relevant keywords for each seed term. These semantic keywords are not just synonyms or variants of the seed term, but they actually make up a cluster that covers all aspects and subtopics of the main keyword.
When you cover all these related keywords in your content, it not only boosts your SEO but also makes you a topical authority in that category. Some AI tools, such as Semrush, even create a comprehensive keyword strategy for you based on your searches.
For example, we used the seed term ''AI content writing tools,'' and Semrush provided us with a keyword strategy that included pillar pages and associated keywords.
Real-Time Analysis and Competitor Benchmarking
With AI tools like Semrush that update every day, you get real-time data not only for your website but also for your competitors. You can monitor how your competitors' keyword rankings change on SERPs and take measures accordingly.
Similarly, AI identifies content gaps between you and your competitors so that you can bridge them by creating content on those topics. For example, we used the Semrush Keyword Gap tool to find missing keywords on our website around ''content writing tools'' that Backlinko was using. The tool took less than a minute to show us the list.
Efficiency in Automating Repetitive SEO Tasks
Part of the reason enterprises and SEO agencies use AI is that it automates repetitive SEO tasks like keyword audits, SERP analysis, position tracking, and search volume forecasting. You can even set up alerts to notify you when a metric shifts for your website.
Since everything is happening in real time and without your intervention, you save a lot of time. Besides, the accuracy and consistency with which AI tools perform these tasks are unparalleled compared to manual work.
AI Keyword Research Strategies to Implement
The following AI keyword research strategies can help you make the most out of your AI SEO tools.
Leverage AI for Question-Based Keyword Research
Creating content around question-based keywords is a great way to appear in featured snippets and AI Overview. It also lets you target the People Also Ask question and increase your website's chances of being clicked on even if it's not the first in the search results.
For example, Semrush lets you filter keywords by Questions. In the Keyword Overview tab, you can see two main things about your search terms:
- Keyword variations
- Questions
Pick questions from here and add them to your content.
Implement Semantic Search and Topic Modeling
What you want is to be seen as an authority on the topic you're covering in your content. For that, you should create topic clusters and incorporate all of them into your content. Basically, leave no base unturned.
Since AI tools like Scalenut create these clusters based on user intent, you're covering all the bases. You'll be serving content that an AI thinks is most relevant to a particular user's search query. This means you can rank for multiple keywords within one piece of content as long as they are all related to the same topic.
While you're at it, don't forget to look at what your competitors are doing. Use the gap analysis feature from Semrush, as we've explained earlier, to find the topics that are missing on your website. Then, create content around them.
Track Competitors with AI-Based Competitive Analysis
Make sure you're looking at your competitors' online presence just as much as your own. After all, you can only beat them if you know what they're up to.
With AI tools, you can keep a continuous eye on your rivals' SEO strategies, their keyword rankings, and the traffic to their website. For example, we use Semrush to monitor our competitors, including SproutSocial and Grin.
We can check their top pages and audience overview to get an idea of their content strategy and target audience. This helps us adjust our own SEO tactics to better compete with them.
Automate Keyword Gap and Content Gap Analysis
Just like you're constantly updating your content, so are your competitors. So, automate content gap analysis through Semrush to identify which keywords they are ranking for, but you're missing on your website. These data-backed content maps can help you create relevant content to fill any gaps in your website's content.
For example, we found the keyword gap for the term ''SEO tools'' with two of our competitors, SproutSocial and Hootsuite. Semrush gave us a list of keywords and their search volume that our competitors were using in their content but we weren't.
This insight provided us with a great opportunity to create new content around those keywords and increase our chances of ranking higher on search engines.
AI-Enhanced Local and International SEO
AI search tools also help refine your geographical SEO strategies, whether they're international or local. For example, Ahrefs supports keyword research in over 40 languages, and its AI technology shows you the keyword variation that captures the most relevant nuance for your target location.
Similarly, Semrush has a Listings Management feature that provides you with a report on your local business's visibility in seconds. It also shows you the directories in which you should list your business to increase your local reach.
How Effective Are AI Tools Like GPT for Keyword Research, and Where Do They Hit Their Limits?
In our article about ChatGPT sorting keywords into clusters, we mentioned that even though ChatGPT can help conduct keyword research and clustering for smaller websites, it's not effective for larger websites with a significant amount of data.
Just like free AI marketing tools, GPT and Gemini are suitable for basic keyword research. They can help expand seed keywords into long-tail keywords and provide suggestions for related keywords. We have covered more of ChatGPT's use cases in our article on ChatGPT SEO.
However, these AI tools have quite a few limitations. First, they can't process large amounts of data like a specialized tool like Semrush can. We've already talked about how Semrush's database has billions of keywords. It's not the same for ChatGPT.
Secondly, GPT can't conduct competitive analysis. It won't tell you which keywords your competitors are targeting and how they're ranking for them.
More importantly, Semrush updates daily, while ChatGPT's last update came in 2023. A lot has happened since then, especially with the new Google Core update. While Semrush is on top of these new trends and updates, ChatGPT is not.
However, AI tools like GPT and Gemini can still be useful in certain situations. For example, they can help with brainstorming new keywords or identifying long-tail keyword opportunities. They can also assist in finding new topic clusters or content ideas based on trending topics. But, their lack of continuous updates and data sources as extensive as Semrush or similar AI keyword research tools for SEO make them less reliable for in-depth SEO research and analysis.
Let AI Lead the Way to Higher Rankings
From AI trend analysis tools to keyword clustering tools, there's so much potential in AI SEO tools for businesses that want to keep leading in the new digital world. The AI tools we've mentioned in this guide, such as Semrush, Moz, and Ahrefs, serve as repositories for keyword data. Not only that, they take keyword research a step further with competitor insights, AI-built strategies, AI content writing, gap analysis, and personalized recommendations.
When using these tools, make the most out of their features. Often, a single feature won't give you all the information you need. Instead, combine different features for a more comprehensive overview.
For example, we use the Keyword Magic Tool to find keywords and then go to the Keyword Overview tab to see its keyword difficulty % for our website. If it's low, we can then use the Strategy Builder to create a content plan.
See how strategic this is? Now, you try.

How do AI SEO tools help with search intent?
AI SEO tools use NLP to analyze the underlying intent behind a search query. They get an insight into the situation and behavior that led to the search query, providing you with the right content angle to take when using those keywords. Some AI SEO tools can further place keywords into clusters based on the search intent.
How do AI SEO tools differ from traditional keyword research tools?
