You may know that the site rankings to rely on some of the previous, improve SEO optimization is a key factor. This requires you to understand the principle of SEO optimization. In fact, the search engine for each site has set the site level index, Google called it PR (PageRank) value, Sogou became SR (Sogourank), although Baidu did not disclose the site level index, but it is recognized that, Baidu should also give each site a similar level of index parameters, otherwise, people each search to recalculate the level of each station, it is not very troublesome, so we think that this parameter exists, each search only need to be ranked according to the current level, of course, ranking may be more than the site level of this factor, But certainly a very important factor. Let's call it the website level index. In theory, the higher the site-level index, the more advanced the search engine rankings. In other words, the website level index is improved, the search engine ranking is very likely to lean forward.

Different search engines, the method of computing site level index is not the same, but one of the basic algorithms is to look at your external links. The old saying is good "content is king, outside chain is Emperor", if other legal website gives you more external links, it is equivalent to give you a friendly vote, your site level index is higher. Also, the higher the level index of an externally linked web site, the more important its voting weight is, and the higher your site level index is.

In this way, adding more high-quality external links to your site is one of the most effective ways to improve your site-level index. As we go to a strange place, if there are many eye-catching signposts to guide you, you can quickly find your destination. On the contrary, we have a great effort to do so, and we don't necessarily find it. Those signposts are actually the equivalent of an external link to your site. Since increasing the quality of the external links to improve the level of the site index, then we find ways to increase the number of high-quality outside the chain. So how do we add external links to the site? There are many ways to increase the external links, I think you can write some of the user has a high value of the article, in the article appropriate place to embed your own site, when users reprint your article, your embedded Web site address is also reproduced, This automatically lets more people know your site, so the external links will increase. In addition, you can also write some original articles on their website, to Baidu know to answer questions, the end of the article link on their own site, the same, your article reproduced more, the site will be corresponding increase in links. A more direct approach is that you can go to a higher-profile site, or the site related to your site to apply for links, in the application of words to be sincere, so that there is a chance to quickly get a lot of high-quality links.

External links increased, your site level index also increased, at this time in the search engine rankings may also be on the front, the purpose of promoting the site is basically reached. Of course, external links should be good quality, not too good links to your site may not have much effect, and even make you feel bored. At this time, you can go to Baidu Webmaster Tools, the use of rejection of the chain of methods, will not need to be rejected outside the chain, so as not to your site adversely affected. In addition, when we build a friendship link with other website construction peers, is not the more the better, the best friendship links to keep under 20-30, too many links to the friendship is not convenient to maintain (often check whether they are K), will also disperse the weight of your site, not only for you have no positive effect, but will affect the ranking of your site.
