With the development of easy-going web technology, more and more enterprises publish their site via Content distribution network Technology (CDN) online. Instead of just hosting the site on a single server, as in the past.

The use of this new technology may lead to some questions about search engine optimization, the main concerns are as follows:

1: Through the use of content distribution network, the site may have more than one IP;

2: There are many sites will use the same IP;

3: Sites that are distributed around the world may affect the specific location of specific sites (related to local search).

Google will not treat sites that use content distribution networks differently, according to Google engineers, and sites that use content distribution networks will be properly captured and indexed by Google. If the site is distributed through CDN technology on different host servers, there may be a problem, that is, there is a lot of duplication of content, so Google suggested that the use of CDN should be used when using the Rel=canonical attribute standard way to avoid duplication of content generation. As shown in the following figure.

One way the search engine recognizes the location of a site is through the host's IP. If we use CDN to publish our site, our site may be associated with many IP locations, and the search engine will link our site to an incorrect location based on IP. The solution to this problem we can through Google Webmaster tools, to our site to do a proper geographical setting.

According to Baidu's search engine guidelines, when talking about the impact of the CDN on Baidu SEO, Baidu said: "Baidu crawl site is like a user to visit the site, once users can access the content of the site, Baidu can also carry out the relevant content of the crawl."

When we are properly designed and implemented, using CDN can improve the load speed of the site by increasing the access bandwidth and reducing the redundancy of the data. For search engines, such as Google, a determination of the crawl efficiency of the algorithm is through the server for search engine spider response time speed. A reasonable use of CDN can not only improve the user experience, but also make our site more friendly to search engines. In conclusion, we can say that using CDN is a positive effect for our SEO.
