What free SEO tools help you fix
A free tool is only useful if it leads to a change on the site. These are the most common wins.
Indexing and technical issues
Pages blocked from search engines, broken redirects and slow pages that hurt both users and rankings.
Weak on-page optimization
Missing or duplicate titles, thin content and pages that compete for the same keyword.
Link gaps
Sites that link to competitors but not to you: a practical starting point to build links.
Uptime and trust
A certificate about to expire or a server that goes down at night, caught before customers notice.
Missing from AI answers
Insights on which sources AI relies on, so you know where your brand needs to appear.
Do you have to pay for SEO tools?
Not for everything. Google Search Console is free and essential: it shows how Google sees your site, which queries bring traffic and which pages have problems. Google Analytics and Keyword Planner are free too. Free tools like these give quick answers to one-off questions and help you test an idea before you invest in it.
Paid SEO tools earn their price on regular work: tracking rankings for many keywords every week, crawling a large site on a schedule, keeping a full backlink database, monitoring AI answers over time. That data costs money to collect for every vendor. If you need that, see the platform or our SEO services.
How we picked these tools
We started from the questions people search for most when they check a website: is my SEO in order, who links to me, how strong is a domain, is my certificate fine, is the site down. Then we added the question more businesses ask now: does AI recommend us. Every tool page explains what the tool analyzes and how to read the result, so it stays useful even before the tool opens. Keyword research and rank tracking are part of the platform: see the rank tracker and keyword research.
FAQ
What is the best free SEO tool?
Google Search Console. It is free, comes from Google itself and shows indexing, queries and errors for your site. Free checkers add what Search Console does not show, such as competitor links or AI answers.
What tools do I need for SEO?
At minimum: Search Console, a site audit tool, a rank tracker, a keyword research tool and a backlink checker. Today it also helps to see how AI assistants answer questions in your niche.
Are these SEO tools free?
Yes. The tools on this page are free and are in early access now. Leave your email on a tool page and we will tell you when it opens.
Can ChatGPT do an SEO audit?
It can review a single page you paste, but it cannot crawl a site, check status codes or see backlinks. Use a crawler for the audit and AI to explain the results.
Do free SEO tools have limits?
Usually yes: a number of checks per day or a shorter report. Regular monitoring of many pages and keywords is what paid plans are for.
