| subdomain | A separate section that exists within a main domain. For example: |
| cloak | Cloaking is the black hat (and not recommended) practice of serving different content to Google than as seen by users. It is a technique that is generally still used only by spammers and those with malicious intent. |
| internet explorer | Microsofts web browser. |
| link decay | Noun phrase. The process by which links vanish, either as they are removed from pages or the pages themselves are removed from the Web. Moving content from an old URL to a new URL without a supporting redirect is another form of link decay. Disavowing sources of links is another form of link decay. Adding the nofollow attribute to the linking page or the link A element also contributes to link rot. |
| orphaned page | A web page that is not linked to any other page on a website. |
