About the Website Technology Checker
Knowing what a site is built on changes how you audit it. The website technology checker reads a public page's HTML and response headers to detect the CMS, the e-commerce platform such as Shopify, WooCommerce, Magento, Wix, Squarespace or BigCommerce, JavaScript frameworks, CDN, web server and common SEO plugins. For each platform it adds SEO tips, such as typical duplicate URL patterns or settings worth checking.
Agencies use it before a pitch or audit, and store owners use it to see what competitors run on. Detection relies on visible fingerprints, so a heavily customized or well-hidden setup may show fewer results; nothing is detected from private systems, and only public URLs can be checked. Treat the result as a strong clue and confirm details with the site owner before planning migrations or quoting work.
How to use it
- Enter the public URL of the website you want to inspect.
- Review the detected CMS, platform, frameworks, CDN and server.
- Read the SEO tips for the detected platform.
- Use the findings to plan your audit or proposal.
Frequently asked questions
How does the tool detect a website's platform?
It looks for fingerprints in the page's HTML and HTTP headers, such as generator meta tags, characteristic file paths, cookies, script names and server headers. These are publicly visible signals. It does not log in or access any private part of the site.
Why might a technology not be detected?
Some sites remove generator tags, rename asset paths or route everything through a CDN that hides server details. Headless setups can also mask the CMS behind a custom front end. In those cases the checker reports only what it can see with reasonable confidence.
Does the platform a site uses affect SEO?
Any major platform can rank well when set up properly. Each has its own common issues, such as Shopify's collection-based product URLs or WordPress tag and archive pages. Knowing the platform helps you check for those known issues first. The checker's tips cover these.
