Frequently Asked Questions
What is an SEO checker?
An SEO checker is a tool that scans a webpage's HTML and reports on the on-page, technical, content, image, link and structured-data factors that influence how well it can rank in search engines like Google.
How does the Free SEO Checker work?
Enter a URL and the tool tries to fetch and parse that page directly in your browser. If the site's server blocks cross-origin browser requests (a common CORS restriction), you can instead paste the page's HTML source code and the tool will analyze it exactly the same way, entirely on your device.
Is this SEO checker free?
Yes. The Free SEO Checker from SEO Service in Sri Lanka is completely free, requires no signup or credit card, and runs unlimited audits directly in your browser. It checks title and meta description length, heading structure, image alt text, canonical tags, structured data and other on-page factors, then returns a prioritised list of what to fix. There is no obligation to buy anything afterwards.
Does the tool improve my Google ranking?
The tool itself does not change your rankings — it identifies the SEO issues holding your page back. Fixing the flagged issues, or working with an SEO specialist to fix them, is what can improve your visibility in Google over time.
What SEO factors does it check?
It checks meta tags, title and description length, heading structure, word count and readability, image ALT attributes, internal and external links, HTTPS and canonical tags, robots.txt and sitemap.xml, language and viewport tags, plus JSON-LD schema, Open Graph and Twitter Card data.
Can I use the tool on any website?
You can try any public URL. Because browsers enforce CORS security restrictions, some sites cannot be fetched directly by JavaScript — in that case, use the Analyze HTML option and paste the page's source code instead.
