Why view the source code?
The source shows the HTML your server really sends. It is useful to check title tags, meta tags, canonical links, structured data and hidden problems. If something you expect is missing here, a search engine may not see it early either.
Frequently Asked Questions
Is this the same as the browser “View source”?
It is very close. The HTML is fetched by our server, so it shows what a bot receives and not what JavaScript adds later. It also shows headers and redirects, which the normal view-source does not.
Why can I not open my page?
Some websites block automated visits, need a login, or are down. The page must be public.
Why is the source cut?
Very large pages are cut at about 1.5 MB to keep the tool fast. The note at the end of the source tells you.
Why are cookie values hidden?
Cookies can hold private data, so we only show that a cookie was set and not its value.
What do the security headers mean?
They are extra instructions your server sends to browsers to block attacks such as clickjacking and mixed content. A tick means the header is present.
Can I check any website?
You can check any public page. Private network addresses are blocked.
