- One of the meta tags, in the HTML header of a web document that contains a brief description of the contents of the document itself. The meta-description is not normally visible in a web browser while viewing the page it describes–one must “view source” to see it.
The meta-description is visible on a SERP, however. It is often the bit of text below a link on the SERP. Meta-description is not believed to influence the positioning of a page on a SERP, but it may inflence whether a human wants to click the link above it. As such, meta-description is a curious SEO tag that doesn’t focus on machine algorithms but instead effects human factors of search engine optimization.
