A 200 is not enough. Check the words.

Pages fail politely: the server answers 200 but shows "Something went wrong". Keyword monitors catch exactly that.

Must appear, must not appear

Tell the monitor which text must be on the page, such as "Add to cart", and which text must never be there, such as "Database error" or "Warning:". If either rule breaks, the check fails and alerts go out.

Typical uses

Checkout and login pages, pricing tables that must show the right price, maintenance banners that should not be visible, and detecting defacement.

Frequently asked questions

Does it render JavaScript?+

No. Keyword checks look at the HTML the server sends. For client-rendered apps, monitor an API endpoint or add a server-rendered health page.
