The essential free SEO toolkit

Google Keyword Planner: requires a free Google Ads account. Provides search volume data and keyword ideas directly from Google's own data.

Free tools for specific SEO tasks

Screaming Frog SEO Spider (free up to 500 URLs): crawls your site to identify broken links, duplicate titles, missing H1s, redirect chains and pages without internal links. Ahrefs Webmaster Tools (free): provides limited but valuable backlink data for your own site. Ubersuggest (free tier): keyword research with basic volume estimates and competitor overview. AnswerThePublic (free tier): visualises question-based search queries around any topic - useful for FAQ content planning.

When to invest in paid tools
