How to Check Your Website's SEO Free, With No Sign-Up

Why most "free SEO checkers" ask you to sign up

Many online SEO checkers show a score, then hide the actual list of problems behind an email form or a trial. That is how they find sales leads. It is not wrong, but it is frustrating when you only want to know what is broken on one page.

The good news is that the most useful checks need no account at all. Here is the order we use when auditing a page.

Step 1: Is the page indexed?

Search Google for site:yourdomain.com/your-page. If the page does not appear, nothing else on this list will help until you find out why. Common causes are a noindex tag, a robots.txt rule, a canonical tag pointing elsewhere or a brand-new page Google has not crawled yet.

If it is your own site, Google Search Console (free, needs a Google account you probably already have) has a URL Inspection tool that tells you exactly why a page is or is not indexed.

Step 2: Check the on-page basics

These are the checks people skip most often, and they take seconds to fix:

• Title tag: unique, about 50 to 60 characters, with the main topic near the start.
• Meta description: about 120 to 160 characters that would make you click.
• One H1 that matches what the page is about.
• Logical headings: H2s for sections, H3s inside them, no skipped levels used only for styling.
• Alt text on every meaningful image.
• Canonical tag pointing to the page itself (or to the main version if there are duplicates).
• No broken links in the content.

You can read these by hand with View Page Source, but an on-page SEO checker extension does it in one click and shows the counts.

Step 3: Test speed and Core Web Vitals

Open PageSpeed Insights, paste the URL, and look at the mobile results first. The three numbers that matter most are LCP (how fast the main content appears), INP (how quickly the page responds to taps and clicks) and CLS (how much the layout jumps around). If real-user data is shown at the top, trust that over the lab score underneath.

Step 4: Validate structured data

Paste the URL into Google's Rich Results Test to see which schema types Google can read, and the Schema Markup Validator for a full list of errors. Make sure the markup describes what is actually visible on the page.

Step 5: Check if AI tools can read and cite it

This is the step most free SEO checkers leave out. AI answer engines such as ChatGPT, Perplexity and Google AI Overviews prefer pages that:

• answer the main question in the first couple of sentences,
• use questions as headings,
• show an author and a last-updated date,
• include specific facts and links to sources,
• keep key text in the HTML instead of loading it with JavaScript,
• and do not block AI search crawlers in robots.txt.

We cover this in more detail in AEO vs GEO vs SEO and how to rank in ChatGPT.

Doing steps 2, 3 and 5 in one click

We built SEO AI Assistant because we got tired of switching between five tabs to do this. It is a free Chrome extension that opens in the side panel next to the page you are checking. Press Analyze This Page and in about 10 seconds you get:

• three scores out of 100: SEO, AEO and GEO,
• 39 checks, 13 for each, with what to fix and where,
• a Core Web Vitals estimate, entity extraction and a schema readiness check,
• an Excel export and a ready-made ticket for Jira or GitHub.

The free plan needs no account and no card. It reads only the page you choose to analyze; to write your recommendations it sends the page URL, title, meta description, element counts and check results to our server, where it is not stored long-term (see the privacy policy). Step 1 (indexing) and step 4 (Google's schema test) still need Google's own tools, and we recommend using them alongside it.
