Can say search engine algorithm is inseparable from the link, then the link in the search engine is also one of the essential factors, so far to the future link algorithm will become more and more complex. There are four basic ways to evaluate a link to a Web page:

Number of Links:

Use the link command to query the reverse link for the site. In general, the number of links to more links to the site will be less linked to the site ranked higher. However, not all links are equal, below exactly.

Second, link quality:

Blog, I believe that everyone is familiar with it, in the blog group, everyone has their own opinions and ideas, but some people's opinions more valuable than others. The idea of creating links through soft text is no different. The link to a Web page is the endorsement of that page, search engine by check link source site link 17891.html "> popularity to judge the weight of the. Thus, if a highly authoritative site links to your site, it is tantamount to giving some of its authority to your site. The search engine ranked the top page rankings from many high-quality sites to link, or even more complex. Search engine based on the number of links in a mathematical way to calculate the authority to transfer to each link-a high authoritative web page with only 5 links transferred to the authority of each link page is more authoritative than a Web page with 50 links authoritative. This theory is only so much authoritative, The more the number of links, the lower the recommended value for each linked page.

Third, the text link:

Visitors click on the link text, style Yyan think this is very heavy search engine. Text links are a key factor in search engine algorithms-search requests tend to return linked pages that contain search-request keywords in text links.
For example, such as "SEO" a Web site began to attract a lot of links to "SEO services" link, then the search for the inclusion of these words SEO page ranking will be higher than ever.

Iv. Link dependencies:

Links from content-related sites are also a key factor in ranking search requests. When we mention the following "content dependencies." The relevance of the content is that information is about a topic (or topic or title)-it's not enough to use similar words in text links, because words can have different meanings in unrelated topics. Outside the text link, the search engine looks at the words around the text link, viewing the entire page or even the entire link source site. Why? Because stations related to search request topics provide links that are more relevant than other sites.
Random links from popularity sites do not have the same authority as links from both popular and highly correlated sites.

Search engines can consider so many complex factors in such a short time between search requests and search results, which is pretty fast, but the search engine does. Search engines think that high page ranking factors are those with many high-quality links to the page. The high search request ranking factor is those that have a lot of access to links from many content-related sites and also include search-request keywords in text links. Note: The style is also exploring how to improve the popularity of the Web page links, if you are interested can discuss together.
