Google attaches great importance to website links, which is also reflected in the evaluation of exported links (out-going/outbound links. First, make sure that your website is "properly linked to other sites". That is to say, if your website only has external reverse links but does not export links, even if you have successfully registered a Google search engine, it will have a negative impact on your website's performance in the search results.
Of course, it is rare that the website does not even have an export link, unless you deliberately do so. Under normal circumstances, you will naturally add links to some other websites on the webpage to lead visitors to what we think is important or can provide more valuable information. This is the so-called"Search engine Law 2".
When you hand over visitors that are not easy to attract to others, it not only helps Google, but also provides information retrieval in general, you have also done a good thing for other searchers, because your links will allow search engines, including Google, to more accurately determine which information is most valuable to users. That's why Google recommends "link to other sites ".
However, please note that there is also a prefix "properly", which means that you can connect to other websites, but you cannot do what you like, or Google will give you a good look! So how is it "properly "?
First of all, it is also the most important thing to connect a link to something that you think the visitor is most interested in. We will do this without having to go into details.
Second, do not set too many export links on the homepage. This is not a clear requirement of Google, but an experience we have learned from practice. More than once, we have seen almost all of the websites on the homepage as export links. PageRank is gray, which is clearly identified by Google as websites with no value included.
Another point that is easily overlooked is to check whether the existing export link is connected to a website that has been punished by Google. Once found, remove the connection as soon as possible, otherwise, it will be regarded by Google as a member of "bad neighborhood" and be punished.
