Free SEO tool

Check your website's SEO in seconds

Enter any address for a free snapshot of its homepage: the basics Google reads, whether AI crawlers may fetch it, and how fast it is for real visitors.

Reads your homepage, robots.txt, llms.txt and sitemap in a few seconds, then Google's speed data.

What it does

The essentials, checked the way search engines see them

Want this across a whole website? That is Site Audit in the GrowthHasten product.

The checker fetches your homepage the way a crawler does and reads what it finds: the title and description Google may show, the H1, whether the page is allowed into the index, and whether it is served securely.

It then reads your robots.txt to see which AI crawlers may fetch the page, looks for an llms.txt, counts the pages your sitemap lists, and asks Google for the page's Core Web Vitals.

It is a snapshot of one page. The GrowthHasten product runs the same kind of checks across every page of your site and ranks each problem by your own Search Console data.

Title, description and H1

What search engines are told the page is about, with length warnings where Google is likely to cut it short.

Indexability

Whether Google may index the page: status code, noindex in the page or headers, and robots.txt rules.

AI crawler access

Which of GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended and CCBot your robots.txt allows.

robots.txt and llms.txt

Whether each file exists, and the sitemap your robots.txt points to.

Core Web Vitals

LCP, INP and CLS from real Chrome users via Google, with a labeled lab test when a site has too little traffic for field data.

Your page count

How many pages your sitemap lists, so you know what a full analysis would cover.

How it works

How the Website SEO Checker works

One request to your homepage and a few to the files beside it, back in a few seconds. Google's speed data follows shortly after.

  1. 01

    Enter an address

    Any public website. A domain like example.com is enough.

  2. 02

    We read the homepage

    Its HTML, headers, robots.txt, llms.txt and sitemap, the same way a search crawler fetches them.

  3. 03

    Google measures speed

    PageSpeed Insights returns real-user Core Web Vitals, or a lab test when there is not enough traffic data.

  4. 04

    Read the snapshot

    Each check is marked good or needs attention, in plain language. Then analyze every page free if you want the full picture.

Who it is for

  • Freelancers and agencies sizing up a prospect's website before a call
  • Site owners who want a quick health check before a launch or redesign
  • Anyone wondering whether AI crawlers can read their site
  • Developers confirming a robots.txt or noindex change went live

Questions

About Website SEO Checker

Is the Website SEO Checker free?

Yes. It runs on this page with no sign-up. You can run five checks an hour.

What does it check?

Your homepage's title, meta description, H1, indexability, HTTPS, robots.txt, llms.txt, which AI crawlers may fetch it, Core Web Vitals, and how many pages your sitemap lists.

How is it different from a full analysis?

The checker reads one page. The GrowthHasten product reads every page (up to 900 on the free plan), scores ten categories and ranks each problem by your own Search Console data.

Do you store what I check?

We keep the snapshot for 30 days so it can carry over if you sign up, and count checks per IP address for one hour to stop abuse. The checker only reads public pages.

Why are Core Web Vitals sometimes a lab test?

Google only reports real-user data for sites with enough Chrome traffic. When there is not enough, the checker shows Google's lab test instead and labels it as one.

Beyond one page

Want the whole picture?

Website SEO Checker does one job. The GrowthHasten product analyzes your whole website, joins what it finds to your own Google data, and ranks the work by what to fix first.

Free plan: one website of up to 900 pages, re-analyzed every month. No card.
