RankBrain

Keyword Research Tool

Collects live autocomplete suggestions about a topic, grouped into questions, comparisons and more.

We fetch the page for you. Our server fetches the public address you enter and reads the response. Nothing you enter is stored. Free, no account.

Finding the problem is the first half.

RankBrain works these phrases into the titles, headings and copy of the pages that should rank for them.

RankBrain works on websites built in code, through the AI tool you already use (Cursor, Claude Code, Codex, ChatGPT).

How it works

You know the topic. You do not know the words people type. This tool asks the autocomplete services of web, video and shopping search for your phrase, on its own and with question words, qualifiers and each letter of the alphabet. Results come grouped as questions, comparisons, buying terms and the A to Z expansion.

  1. 1

    Enter a starting phrase. We ask the autocomplete services of web, video and shopping search for it, on its own and combined with question words, qualifiers and each letter of the alphabet: about 60 requests.

  2. 2

    Autocomplete offers suggested phrases, not search counts or proof of demand. Treat them as ideas to investigate.

  3. 3

    Results are grouped: closest suggestions, questions, qualifiers such as "for" and "near", comparisons and buying terms, and the A to Z expansion. Copy any group or export everything.

What it does not do

  • No licensed search-volume data is included. Search Console shows impressions and clicks for your property, not total market demand.

  • Suggestions differ by country. Choose the country your customers are in.

When a source is busy or a site does not answer, this tool says so. It never fills the gap with a guess.

Questions

Why are there no search volumes?

This tool has no licensed search-volume dataset. Autocomplete gives suggested phrases, not proof of demand or a count. Search Console shows impressions and clicks for your own site, not total market search volume.

Why do my results differ from what a colleague in another country sees?

Autocomplete is local. The suggestions we get depend on which country's search service answers, so the same starting phrase returns different phrases for different countries. Pick the country your customers are in before you run the search, and read the list as suggested wording to investigate, not measured demand. The grouping stays the same.

What do I do with the groups once I have them?

Read each group as a job. The questions group tells you what people want explained. Comparisons show what they weigh before buying. Qualifiers and buying terms sit closer to a decision. Copy a group or export everything, then use the phrases as page titles and headings for pages you can actually answer.
