Also speaking of search engine and site production optimization problems, today's special search engine on the link principle of things, I hope to be able to help the vast number of novice friends.

Links and the development of search engines

In the early days, probably is in Google and other large-scale professional search engine was born, when the search engine is often based on the keyword in the page matching, according to the relevance of the keyword rankings, we should be able to imagine that time, we see the rankings must be a flawed. As long as you can do the site, add some keywords in the page, piling up, or add some and the content of the Web page is not related to the hot words, you can get a better ranking, and it is not difficult. So, at that time the site is very easy to make in terms of rankings, there is no such complex optimization problem now. Now, as search engines ' algorithms become more sophisticated, search engine rankings become less easy. Now the search engine on the link, added a very good link analysis function, by calculating the relevance of the link, so that can reduce a lot of garbage unrelated links. The main purpose is to improve the user experience.

Now the search engine, in the rankings of the linked factors, increase the relevance of the calculation, so that can also make the traditional keyword no way to match can not be ranked files can be processed. such as pictures, video files are not easy to do before keyword matching, but can be analyzed through the link, through the link of information, search engines can be pictures and video content ranking. So, you can be very aspects of the search picture video content. We can see in Baidu, there is a burst of different content search classification, video, pictures, music, etc., these in the optimization, often also through the link analysis of the relevance of these content. Many web site production companies have been through the video, image optimization to obtain a lot of traffic.

Understanding the relevance of links

Here said that the relevance of the link, because the search engine of this algorithm is more complex, so, here can not be a very specific amount to explain, can only be very abstract text to let you understand the links related issues, so that the broad masses of novice friends easy to understand. Search technology through the link to large-scale content analysis, including page mate title, keywords, content page keyword density, anchor text and so on to determine whether the link content is relevant. This is why we have been emphasizing to find outside the chain to find the same industry site, internal links, such as modularity.

Many friends I am afraid have been very interested to know more links related issues, the impact of the ranking is really no way to intuitive understanding, is not easy through data statistics and other means to make, because no one can get the engine on the linked database, can not quantify, many times, We need to optimize the site production of technical personnel to observe and accumulate experience.
