2. Ahrefs: best for backlinks
Why it wins
Ahrefs has a fast, large backlink index and excellent Site Explorer, Content Gap and Link Intersect reports. The $29 Starter plan suits light keyword research and competitor monitoring, and Ahrefs Free gives site owners audit and backlink data for their own verified sites. See Ahrefs pricing.
Watch out for
Lite costs $129 a month, Standard $249 and Advanced $449. Usage limits on lower plans can feel tight for daily research.
3. SE Ranking: best value
Why it wins
SE Ranking combines rank tracking, website audit, keyword research, competitor analysis and backlink tools at a lower price than Semrush or Ahrefs. It's popular with agencies because of white-label reports and flexible tracking. See SE Ranking pricing.
Watch out for
The keyword and backlink databases are smaller than Semrush's and Ahrefs'. There's no free plan, only a trial.
4. Moz Pro: best for beginners
Why it wins
Moz is approachable and well documented, and its Domain Authority metric is widely used. Standard costs $99 a month, or $79 on annual billing, and MozBar and limited keyword research are free. See Moz pricing.
Watch out for
Fewer advanced features than Semrush or Ahrefs, and data limits on the entry plan.
5. Google Search Console: best free tool
Why it wins
It shows the queries that bring impressions and clicks, which pages are indexed, Core Web Vitals, structured data issues and top linking sites, all from Google itself. Every site should use it.
Watch out for
It only covers your own site, with no competitor data or keyword ideas beyond your current queries.
6. PageSpeed Insights: best free speed test
Free reports on Core Web Vitals and loading performance for any URL, with suggestions for fixes. Pair it with Search Console's Core Web Vitals report. See technical SEO checklist.
7. Google Keyword Planner: free volume ranges
Part of Google Ads, free with an account. It shows volume ranges and keyword ideas. Useful for a first look, but less precise than paid tools. See how to do keyword research.

How we chose

What to look for in an SEO tool
- Database size and freshness for your country.
- The reports you'll use weekly: rank tracking, audits, keyword research.
- Limits on projects, keywords tracked and pages crawled.
- Extra costs for users or add-ons.
- Ease of use for your team.
Common mistakes
- Paying for a suite when Search Console and one budget tool would do.
- Comparing monthly and annual prices as if they were the same.
- Ignoring limits on tracked keywords or crawled pages.
- Buying several overlapping tools.
Getting value from an SEO tool in the first month
Week 1: connect Search Console, set up a project and run a site audit. Week 2: fix the critical audit issues. Week 3: research keywords for your next five pages and set up rank tracking. Week 4: run a keyword gap against two competitors and pick three content opportunities. A paid tool earns its cost when it feeds a steady publishing and fixing routine.
Do you need more than one SEO tool?
Most small businesses need one paid suite plus Google Search Console. Agencies sometimes pair Semrush or SE Ranking with Ahrefs for deeper link research.
Our verdict
Semrush is the best SEO tool for most businesses because it covers every core task in one place and has a free plan to start. Choose Ahrefs if backlinks are your priority, SE Ranking if budget matters, and Moz if you want something simple. Use Google Search Console alongside any of them.
