This scanner reads your homepage's HTML and CSS and flags anything hidden with display:none, visibility:hidden, zero opacity, or off-screen positioning. Some of that is harmless leftover markup — but hidden text stuffed with keywords is a cloaking technique search engines actively penalize, so it's worth knowing what's actually there.
What counts as "hidden," and why it's worth knowing what's on your page.
Surfaces every element hidden through common CSS techniques, so nothing invisible on the page stays invisible to you.
Hidden text packed with keywords is a known SEO cloaking pattern — this flags it before a manual review or algorithm update catches it instead.
Catches elements hidden specifically at mobile breakpoints, which can quietly break a responsive layout without ever showing up on desktop.
Old hidden sections often mean leftover markup from a previous redesign — removing them shrinks page weight and simplifies future edits.
Checks for display:none, visibility:hidden, zero-opacity, and off-screen positioning — not just the one most obvious method.
Each flagged element is shown with enough context to find it in your source, instead of a vague "issues found" count.
Still deciding? Here's what people usually ask before running this scan.
It scans your page's HTML and CSS for elements hidden through common techniques — display:none, visibility:hidden, zero opacity, or positioning something off-screen — and reports each one it finds.
The scan runs on the URL you submit. For a multi-page site, run it against your other key pages as well to get the same coverage.
Some hidden markup is harmless leftover code, but hidden text stuffed with keywords is a cloaking technique that search engines specifically look for and penalize — so it's worth knowing which one you actually have.
Yes, indirectly — removing unused hidden sections reduces the amount of markup the browser has to parse, which can shave a little weight off page load.
No — the scan analyzes the static HTML and CSS returned by the server. Elements that get hidden dynamically by JavaScript after the page loads aren't covered by this check.
No — accordions, tabs, and mobile menus all legitimately use display:none for content that expands on click. The tool flags what's hidden; deciding what's intentional design versus leftover clutter still needs a quick manual look.
Viewing source shows you raw HTML, but spotting which of hundreds of elements is actually hidden by CSS — and how — is tedious by hand. This tool does that scan automatically and lists only what's actually hidden.
Same free, no-signup approach — pick whichever check you need next.
