Definition

Hidden text is content that is present in a page's code for search engines to read but is concealed from human visitors through styling or positioning. Google's spam policies treat it as a manipulative practice when used to influence rankings.

Not every off-screen or visually de-emphasised element is hidden text in the policy sense. Google distinguishes manipulation from legitimate techniques such as accessible-only labels, expandable accordions, or content revealed through tabs, which are intended for users rather than to deceive search engines. The concern arises when text exists solely to be indexed while being deliberately invisible to the people viewing the page.

Examples

• Colour concealment

  A page sets keyword-dense paragraphs in white text on a white background so they are indexed but never seen by a reader.

• Zero-size styling

  A site adds a block of links with the font size or opacity set to 0, or positions text off-screen with CSS, to pass link signals without showing them.
