Hiding text or links in your content to manipulate Google’s search rankings can be seen as deceptive and is a violation of Google’s Webmaster Guidelines. Text (such as excessive keywords) can be hidden in several ways, including:
- Using white text on a white background
- Locating text behind an image
- Using CSS to position text off-screen
- Setting the font size to 0
- Hiding a link by only linking one small character—for example, a hyphen in the middle of a paragraph
When evaluating your site to see if it includes hidden text or links, look for anything that’s not easily viewable by visitors of your site. Are any text or links there solely for search engines rather than visitors?
- Images: Use the alt attribute to provide descriptive text. In addition, we recommend using a human-readable caption and descriptive text around the image. See this article for more advice on publishing images.
- Videos: Include descriptive text about the video in HTML. You might also consider providing transcripts. See this articlefor more advice on publishing videos.
