When a user of the internet enters a search term into a search engine, the engine provides a list of web pages with what it considers to be relevant content by using a keyword the user has entered as a reference. When search engines first came about, they would have used link and tag management from many websites, but with so many users in todays' world sharing information across the internet they have had to evolve accordingly to manage the mass number of websites.

Search engines are designed to "meaningfully" sort the websites and display a list significantly related to the keyword. Most search engines keep the specifics of their search algorithms undisclosed. Whatever methodologies work behind it, certain parameters are always present.

Backlinks, sometimes known as inbound links, are helped when considering a website and its visibility. Backlinks are links to a website from another website/s. The popularity of a site is often determined by the amount of inbound links.

SEO backlinks are vital in improving a site's ranking. However, backlinking is not only measured in numbers but in the keyword relevance of the content of the website pointed to and the content of the website that links to it. Also, the text that serves as the link and descriptions attached to it are also evaluated for relevance to the keyword.

Backlinks that are accounted in search engine optimization are not always direct links to sites from other websites, specifically from one site owner to another. Backlinks made by an internet user to a site is also valued in search engine optimization. Social bookmarking enables users to manage and store links to webpage that they want to memorize or share to other people.

When a site becomes bookmarked it helps it with search engine positions as it is considered that the user or viewer of the site understood and liked the content and information provided on the bookmarked webpage. This in turn makes the description more significant and symbolic.

Web directories can also be utilized for backlinking. These directories are online lists that groups webpage links by classification. Directory submission allows owners of websites to forward links to their site for inclusion in the web directory. The site link is placed on its corresponding category and often added with description. These links are considered as search engine references. As with bookmark, more links found in web directories give a higher hierarchy in search lists. Thus, it is common for site owners to send links to multiple web directories.

When executed properly article submissions is a great SEO strategy. Adding or even buying backlinks for a site heightens its chance of appearing well in search engine results. It must be noted however that although quantity of backlinks is a factor search engines look into they also try to evaluate them. Search engines have been updated over time to provide the user with relevant results, so taking this into account for SEO Backlinks a site should have a significant amount of inbound links, and these should be meaningful to related keywords.
