Traditional keyword research tools are excellent at providing metrics such as search volume, keyword difficulty, and competition. But they don't always make it easy to understand all the different ways people approach a topic.
That's where ChatGPT can help.
ChatGPT is useful for brainstorming keyword ideas, understanding search intent, grouping related queries, discovering content angles, and finding questions that your initial keyword list may have missed.
However, it should be used as a research assistant, not as your only source of SEO data.
Step 1: Start With a Broad Topic
Begin with your main topic rather than a single keyword.
For example, if you're researching local SEO, ask ChatGPT:
“Break local SEO into its main subtopics and identify the different questions a business owner might search for.”
This can reveal areas such as Google Business Profile optimization, local keywords, online reviews, citations, Google Maps, and local ranking factors.
Step 2: Map Search Intent
Next, ask ChatGPT to organize your ideas according to search intent.
You can request categories such as:
Informational
Navigational
Commercial investigation
Transactional
This helps you understand what type of content each keyword may require.
For example, “what is local SEO?” needs educational content, while “best local SEO agency” has a stronger commercial intent.
Step 3: Generate Natural Keyword Variations
Once you identify an important topic, ask ChatGPT to generate natural ways users might search for it.
For example:
“Give me 20 natural search queries related to local SEO for small businesses. Group them by user intent.”
This can uncover long-tail keywords, question-based searches, and related phrases that can be useful for content planning.
Remember: these are ideas, not verified search-volume data.
Step 4: Find Content Gaps
ChatGPT can also help you compare competing content.
Provide information from competing articles and ask:
“Identify important questions, subtopics, examples, or perspectives that these articles don't adequately cover.”
This can help you discover opportunities to make your content more useful and comprehensive.
The goal isn't to copy competitors. It's to identify what users may still need that existing pages aren't providing.
Step 5: Validate With Real SEO Data
This is the most important step.
ChatGPT does not replace dedicated keyword research platforms for reliable search-volume, competition, and keyword-difficulty data. Before creating content around an AI-generated keyword list, validate the opportunities using tools such as:
Ahrefs — Check keyword opportunities, search volume, difficulty, competitors, and content gaps.
Semrush — Validate keywords, search intent, competition, SERPs, and related keyword opportunities.
Google Keyword Planner — Useful for discovering keyword ideas and evaluating search-demand ranges.
Combining these tools with ChatGPT creates a much more reliable workflow.
