Hidden text is page content that is visually invisible to users but present in the HTML — for example, white text on a white background, text positioned off-screen, or text behind an image. Search engines may treat intentionally hidden text as a manipulative technique designed to stuff keywords without being seen.
Why it matters: Most hidden text techniques used for keyword stuffing violate search engine guidelines. Legitimate uses include off-screen text for screen readers (properly marked with accessible hiding CSS) and expandable content that is visually hidden until toggled. Avoid any technique that hides text solely to influence rankings.
