From WP:NOT § INTERNET:
Topics that do not satisfy notability criteria are dealt with in two ways: merging and deleting. Articles that may be non-notable can be marked with the {{}} template to make other editors aware of the problem. When such articles being listed for deletion, the articles are discussed at . Alternatively, the proposed deletion process may be used for articles that are uncontroversially deletion candidates, while the {{}} template can be used to mark an article for speedy deletion; see criterion A7 for details.
"Notability" is not synonymous with "fame" or "importance," and even web content that editors personally believe is "important" or "famous" is only accepted as notable if it can be shown to have attracted notice. No web content is exempt from this requirement, no matter what kind of content it is. If the individual web content has received no or very little attention from independent sources, then it is not notable simply because other web content of its type is commonly notable or merely because it exists (see "If it's not notable", below).
When evaluating the notability of web content, please consider whether it has had any significant or demonstrable effects on culture, society, entertainment, athletics, economies, history, literature, science, or education. High-traffic websites are likely to have more readily available verifiable information from reliable sources that provide evidence of notability. However, smaller websites can also be notable. Arbitrary standards should not be used to create a bias favoring larger websites.
Web content is not notable merely because a notable person, business, or event was associated with it. If the web content itself did not receive notice, then the web content is not notable. For example, if a notable person has a website, then the website does not "inherit" notability from its owner. In such cases, it is often best to describe the website in the article about the notable person.
