What we check

14 checks that hold small business sites back

These are the issues we find most often when we audit websites for service businesses, online shops, tour operators and churches.

SEO

Can Google find, understand and show your page well?

Page title: The blue headline in Google results. 30–60 characters, with your main service.
Meta description: The two lines under that headline. A good one wins the click.
XML sitemap: A list of your pages that helps search engines find all of them.
robots.txt: Tells crawlers what to read and where your sitemap is.
Image descriptions (alt text): Helps image search, screen readers and AI understand your photos.

AI search

Can ChatGPT, Perplexity and Google AI Overviews read and cite you?

Structured data (schema): Machine-readable facts about your business: name, services, location.
Social sharing preview: Open Graph tags, so shared links show a proper title and image.
llms.txt for AI assistants: A plain summary of your site written for AI tools.

Speed & mobile

Does the page load fast and fit a phone screen?

Mobile-friendly viewport: Without it, phones show a tiny zoomed-out desktop page.
Server response time: How long your server takes to start answering. Under 0.8 s is good.
Home page weight: Heavy pages and dozens of scripts slow phones down.

Conversions

Can a ready buyer act straight away?

Clear way to contact you: A phone link, email link or form right on the home page.
One clear main headline: One H1 that says what you do and who it is for.
Secure connection (HTTPS): Browsers warn visitors away from “Not secure” sites.

FAQ

About the free SEO checker

Is the SEO checker really free?

Yes. You can check as many websites as you like, there is no sign-up, and results show straight away on the page. If you want the issues fixed, Optimize offers a free, personal audit with a prioritized plan.

What does the free SEO checker test?

It runs 14 checks on a website's home page across four areas: SEO basics (title, description, sitemap, robots.txt, alt text), AI search readiness (structured data, Open Graph, llms.txt), speed and mobile (viewport, server response, page weight) and conversions (contact options, main headline, HTTPS).

What is AI search readiness?

It is how easily AI assistants such as ChatGPT, Perplexity, Gemini and Google AI Overviews can read your site and cite it in their answers. Clear structured data, a plain llms.txt summary and pages that answer questions directly all help. This work is also called answer engine optimization (AEO) and generative engine optimization (GEO).

Is a high score a guarantee of good rankings?

No. The checker covers the technical and on-page basics that hold many small business sites back. Rankings also depend on content, links, reviews and competition, which the full free audit looks at, together with your Search Console data if you share it.

Do you store the website I check?

We keep the address you checked, its score and the time, so we can improve the tool and, now and then, offer help to sites with big, fixable gaps. We do not ask for or store your name or email unless you request the full audit. See the privacy policy.

Can I check any website, including a competitor?

Yes. Any public website works: WordPress, Shopify, Wix, Squarespace, Webflow or custom-built. Only the home page is checked, so results are a quick snapshot, not a full crawl.
