Keyword research has a reputation for being expensive, but most of the signal you need is sitting in free, public sources. Here are ten tactics that cost nothing and consistently uncover terms worth targeting.

  1. 01

    Mine Google autocomplete

    Type your seed term and note every suggestion — these are real, popular queries ranked by frequency.

  2. 02

    Read 'People Also Ask'

    Each expanded question reveals related intent you can answer in one post.

  3. 03

    Scrape 'Related searches'

    The bottom of the results page is a free map of adjacent topics.

  4. 04

    Check Reddit and forums

    The exact phrasing people use in communities makes excellent long-tail keywords.

  5. 05

    Use Google Trends

    Compare terms and spot rising queries before competitors do.

  6. 06

    Raid YouTube autocomplete

    Video search reveals how-to intent that's often easier to rank for.

  7. 07

    Study competitor headings

    Their H2s and H3s are a free outline of the keywords they're chasing.

  8. 08

    Search Amazon and reviews

    Product queries expose buyer-intent language money keywords are built on.

  9. 09

    Pull questions from Quora

    High-engagement questions signal demand and exact wording.

  10. 10

    Read your own Search Console

    Queries you already rank for on page two are your fastest wins.

Combine three or four of these and you'll have a richer list than most paid exports.
