| supplemental index | Supplemental Index refers to Googles secondary database containing pages considered to have less importance. The importance of a page is measured by the number of links pointing to it. If, according to Googles algorithm, a page is depreciated, it will not pass to the target page. It will appear on a supplemental page that will rank in search results only if there are not enough pages in the main index. Supplemental results are rarely rank and, thereby, they dont pull much weight in Google. |
| social media | Platforms (websites and apps) where users can interact with each other, as well as create, share, and consume content. |
| conceptual links | some of the more advanced search engines are attempting to understand links beyond focusing on the anchor text, for example by using co-citation. |
| meta keyword | Meta keyword are html tags that contain most important keyword of a page. Though the practice of adding meta keywords to a web document is still alive, most of the search engines, including Google, ignore them just to prevent keyword stuffing. |
| alt attribute | HTML code that provides information used by search engines and screen readers (for blind and visually-impaired people) to understand the contents of an image. |
