AI-powered keyword research: using ChatGPT and Perplexity to find untapped terms

Module 3: Keyword Research Masterclass | Lesson 30 of 687 | 30 min read

AI chat tools have become legitimate keyword research assistants. ChatGPT, Perplexity, and Claude can surface long-tail terms, map semantic keyword clusters, and identify questions your audience is asking — often faster than traditional tools. The key is knowing how to prompt them effectively and how to validate their outputs before targeting them on your Wix site.

Using ChatGPT for Keyword Ideation

ChatGPT is strongest at brainstorming and semantic expansion. It can generate hundreds of related terms, question variants and content angles for any topic in seconds. Its limitation is that it cannot provide search volume data, so it should always be used alongside a free volume tool like Google Keyword Planner or Ubersuggest.

Effective ChatGPT prompts for keyword research

Seed prompt: "Generate 30 long-tail keyword variations for [your main keyword] including informational, commercial and transactional intent types"
Question prompt: "List 20 questions someone planning to [customer goal] would search on Google"
Semantic prompt: "Create a semantic keyword cluster around [main topic] for a Wix website in the [industry] niche"
Competitor angle: "What questions are people asking before buying [product/service] that competitors are probably not answering?"
Always ask for keywords in batches of 20-30 and sort them by intent after generation

Using Perplexity for Real Question Research

Perplexity is better than ChatGPT for keyword research because it searches the live web and provides citations. Ask Perplexity about your target topic and observe the questions it generates, the subtopics it covers and the sources it cites. The questions Perplexity answers are questions your audience is actively asking in search right now.

Validating AI-Suggested Keywords

Run AI-suggested keywords through Google Keyword Planner to check real search volume
Check Google Autocomplete for the term — if it appears, it is a real query
Search the term in Google and examine the actual SERP for intent signals
Use Ahrefs or SEMrush free features to check keyword difficulty
Discard any AI-suggested term with no Google Autocomplete appearance and no search results page

Best Practice: AI tools excel at quantity and creativity. Traditional keyword tools excel at accuracy and data. Use AI to generate the list and traditional tools to qualify it. Never publish Wix content targeting a keyword that has not been validated with at least one real search volume data source.
