With the development of Web applications, many international sites began to use Content distribution network technology in the site (hereinafter referred to as CDN Technology), the biggest feature of this technology is that the site is no longer the same as in the past just placed on a fixed server. Instead, the site content is distributed around the world's leading CDN service providers. This can be very good to reduce network nodes, improve the speed of the site.

But there are two sides to everything. We can not evade the need to face the use of CDN technology to bring SEO problems. The SEO issues that we may encounter mainly are as follows:

Problem One: If we use CDN technology, sites in multiple locations may appear to have multiple IP problems.

Problem three: Your site may be located in a different geographical location, the search engine may not be able to identify the geographical location, this will affect the local search.
