How to Use AI Keyword Research Tools and Check the Results Page

What AI adds, and what it cannot do

AI is good at language jobs. It can expand a seed phrase, rewrite it the way different people would type it, and label the likely intent.

It is poor at counting. ChatGPT and similar assistants do not have a reliable search volume or difficulty score, and they can state one with confidence anyway. Ahrefs says to use ChatGPT for brainstorming only, and OpenAI has explained that models guess when they are unsure.

Tools by job

Most teams need one data tool, one idea tool and Search Console. Here is what each does and what it costs to start.

Two details are easy to miss. The Keyword Planner help page says you need a Google Ads account with billing set up. It is free to use, but you cannot use it without an account. And Semrush is now part of Adobe: by Semrush’s customer FAQ, nothing changes for customers for now.

The 5-step workflow

1. Brainstorm from a seed. Start with a plain topic, such as “SEO for dentists in Chennai”. Ask AI for questions, problems and comparisons a buyer would type.
2. Validate volume and difficulty. Paste the shortlist into Semrush, Ahrefs or Keyword Planner. Drop terms with no demand, and keep low-volume terms only when they match a service you sell.
3. Read the results page. Search each target on Google. Note which page types rank, and whether people want a guide, a tool or a service page.
4. Group and map. Put terms that the same pages rank for into one group, and give each group one page. Ahrefs does this by Parent Topic, which looks at shared top-ranking pages.
5. Check your own data. Open the Performance report in Search Console. Existing queries with impressions but few clicks often show the next page to improve.

Note the last sentence of that prompt. Telling the assistant not to invent numbers removes the most common error.

Here is how step four might look for the dental example. The terms are illustrative, not researched.

Reading the results page without fooling yourself

Keyword tools show estimates. The results page shows the actual competition, so read at least the top five for every target.

• Intent: Semrush sorts intent into informational, navigational, commercial and transactional, with mixed cases. Check it against what ranks.
• Keyword difficulty: Ahrefs’ score reflects how many sites link to the top ten, so it measures link competition only. Scores differ between tools, so compare within one tool.
• Volume: It is an estimate, often an annual average, and zero-volume terms can still bring leads. Google Trends is relative, from 0 to 100, so use Google Trends for seasonality, not counts.
• Gaps: Look for what the top pages leave out: local detail, prices in a range, a worked example, a clear next step.

If you ask an AI assistant to summarise the results, give it the pages. Check what it cites. ChatGPT’s free plan can now search the web, but it can still misread a page. Treat its analysis as a hypothesis, then confirm it by eye. The SEO Starter Guide also says to write for readers, not for keyword counts.

A free stack for a small business

You can run the full workflow without paying, with tighter limits.

This is enough for a site targeting a few dozen terms. For competitor gaps across hundreds of terms, a paid tool saves real time.

Mistakes to avoid

• Trusting AI volumes. Always replace them with tool data.
• Chasing every suggestion. Pick terms tied to a service you sell.
• Skipping intent. A guide will not rank for a query where Google shows service pages.
• Splitting one topic across pages. Pages that target near-identical terms compete with each other.
• Copying competitor outlines. Use them to spot gaps, then write from your own knowledge.

Final thoughts

Use AI to widen the list and your tools to narrow it. A short list of terms you can match with a real page beats a long list nobody has checked.

Start from a clear seed, validate every number, read the results, and let Search Console show what already earns impressions.
