AnswerThePublic-style question toolsContent ideasQuestions people ask (free tiers vary)

1. Google Search Console

The most important free SEO tool, because it shows real data from Google about your own site: which queries bring impressions and clicks, your average position, which pages are indexed and which have errors. Use it to find pages ranking on page 2 that a small improvement could push to page 1.

How to use it: open Performance → Search results, filter for positions 8 to 20, and improve those pages first.

2. Bing Webmaster Tools

Bing's equivalent of Search Console, with its own site scan and keyword research. Bing data matters more than many think, because Bing's index powers several AI search experiences. Verifying your site takes minutes.

3. Google Analytics

Shows how visitors arrive and what they do. For SEO, look at organic search landing pages and their conversions: the pages that bring customers deserve more attention.

4. Google Keyword Planner

Built for advertisers, but free with a Google Ads account. It gives keyword ideas and search volume ranges. Ranges are broad unless you run ads, so use it for ideas and relative size, not exact numbers.

Compares interest in search terms over time and by country. Useful to check whether a topic is growing, seasonal or fading before you write about it.

6. Semrush free plan

Semrush's free plan needs no credit card and gives a limited number of daily queries for keyword and competitor research. When you need full access for a project, its 7-day free trial unlocks the paid toolkit. See Semrush pricing.

7. Ahrefs Free

Ahrefs offers free site data and issue fixes for websites you own. It complements Search Console with a crawler-based view of your site's SEO health. When you need keyword research beyond your own site, Ahrefs Starter costs $29 a month. See Ahrefs pricing.

8. PageSpeed Insights

Tests a page's speed and Core Web Vitals on mobile and desktop, and lists concrete fixes. Aim for an LCP under 2.5 seconds, INP under 200 ms and CLS under 0.1.

9. Rich Results Test

Checks your structured data (schema markup) and shows which rich results a page is eligible for. Run it on every new page template.

10. Screaming Frog SEO Spider (free version)

A desktop crawler that finds broken links, missing titles, duplicate pages and redirect chains. The free version crawls a limited number of URLs, enough for small sites.

11. Google Business Profile

Essential for local businesses: your listing on Google Maps and in local results. Keep hours, categories, photos and reviews up to date.

12. Question research tools

Free tiers of question-research tools, plus Google's own "People also ask" boxes and Reddit threads, show the exact questions your audience asks. Use them for headings and FAQ sections.

A free SEO workflow for a small business

  1. Verify your site in Google Search Console and Bing Webmaster Tools.
  2. Find quick wins: pages ranking in positions 8 to 20 in Search Console.
  3. Research keywords with Keyword Planner, Trends and Semrush's free plan.
  4. Check technical health with Ahrefs Free and Screaming Frog's free version.
  5. Fix speed issues flagged by PageSpeed Insights.
  6. Add structured data and validate it with the Rich Results Test.
  7. Track progress monthly in Search Console.

Free tools for AI search visibility

AI assistants and AI search features increasingly answer questions directly. To be cited:

  • Make sure Bing can crawl and index your site (Bing Webmaster Tools).
  • Write clear, direct answers at the top of pages, with dated facts and sources.
  • Use structured data validated with the Rich Results Test.
  • Publish an llms.txt file summarizing your key pages, and don't block AI crawlers in robots.txt if you want to be cited.

Common mistakes with free SEO tools

  • Treating Keyword Planner volumes as exact. They are ranges.
  • Ignoring Bing. It is free and feeds AI search experiences.
  • Chasing every speed warning. Fix the issues that affect real users first.
  • Never acting on Search Console. The data only helps if you improve the pages it points to.

A monthly free-SEO routine (30 minutes)

  1. Search Console → Performance: note the 10 pages with the most impressions and a click-through rate below average; rewrite their titles and meta descriptions.
  2. Search Console → Pages: fix any newly "not indexed" pages that should be indexed.
  3. PageSpeed Insights: test your 3 most visited pages on mobile.
  4. Keyword Planner and Trends: pick one new topic with growing interest for next month's content.
  5. Bing Webmaster Tools: check for crawl errors and submit your sitemap if it changed.

Our verdict

You can go a long way in SEO without paying anything. Google Search Console and Bing Webmaster Tools give you real data about your own site; Keyword Planner, Trends and Semrush's free plan give you keyword ideas; PageSpeed Insights, the Rich Results Test and Screaming Frog's free version cover the technical basics. Pay for a tool only when SEO becomes a weekly job and you hit a clear limit, such as competitor backlink research or daily rank tracking for hundreds of keywords. At that point, start with the cheapest plan that removes that specific limit, and review it after three months.
