What Can Tell External Site Links

External links are, in fact, advertising a particular site on the web and how the site is presented on other resources. In short, without such links it would be impossible to find websites on the Internet. Importance is obvious, which means that checking the site for external links is an important component of optimization and current assessment of the technical condition of the resource, which is carried out by regular means without involving experts from outside. Existing search engine optimization tools offer different methods of verification, but they are all based on search engine data. It is quite easy to check external links from the site, but some of the problems identified in this way can be complicated in the process of their localization.

All external links, as noted above, are registered by search engines and their full list can always be found on the administrative panels of all major search engines. The presentation of data can be organized in different ways, but the work of search robots on all sites is exactly the same. Robots collect such links by simply navigating through links from other sites. Incidentally, the information collected with them is also of immense statistical value, both for search engines and for the owner of the resource. Most likely, that site owners do not see even half of that information that is collected by search robots for internal use of search engines. However, given that such information is provided completely free of charge, search engines can be said for this "thank you".

So, the most relevant and perhaps most important is the thematic focus of the content of the sites on which the links to the site are located. This directly affects the "weight" and "credibility" of this link. The weight of the reference is a conditional value that is directly related to the PR of the resource from which the reference is made. The authority of the link depends on how much the keyword associated with this link corresponds to the thematic focus of the resource. If external links come from sites that have a good PR (> 4), then several hundred or thousands of such links help to increase the PR of the site to which they "work". Otherwise, the PR of the site to which the links point, remains unchanged.

If we talk about external links, like those posted on the site under consideration, it can be argued that they increase the "credibility" of the resource. This means that this site "knows" more about other resources on which there is content of a certain semantics. In general, if we talk about the importance of external links for some Internet resource, then this significance is, first, available

Explicit connection with a certain segment of the Network, and, secondly, in the knowledge of the resource itself about the existence of other similar sites. The latter factor is extremely important for search engines, as they rely on data grouped in this way.

In conclusion, we can add that the absence of "dead" links on the site indicates its "correctness" in relation to users and search engines; And the presence of links that do not lead anywhere or not, where they should lead, leads to search fines. The latter extremely negatively affect the overall rating of the site on the Internet. That is why site administrators and all optimizers are struggling for full correspondence of external links to content and navigation of trust sites.
