A Google Webmaster help thread has affected a Web master, which rejected since the changeover to a content delivery network (CDN) its PageRank and search rankings.
A CDN is a way to host your website or parts of your site on servers that are more scalable server resources and bandwidth. Many large websites use CDNs host graphics, videos, and scale their database resources if necessary. Are apart, they are bad for search engines?
The answer is, it depends on how you have configured it. Google index files on clouds, and if you host files on the cloud correctly, as described here you should be fine.
That being said, JohnMu of Google to the webmaster make replied:
I'm not sure, how you use a CDN, it's hard to say, sure. My guess is that you only normal fluctuations with toolbar see PageRank that can happen for a variety of technical reasons (and they usually directly back quickly to). On the other hand, if you, significant changes in the ranking see a change would be not used as follows.Moving images on a new host (provided the URL changes it to a CDN) probably you are fluctuations in the image search until it compromise back down (it takes only a little for the new indexed URLs instead of the old). How we generally JavaScript files would indicate not, you have it to a different host generally unaffected.
In any case, while it can lead to a CDN small temporary fluctuations, making your site help faster often your site much more. Some studies have shown that the higher your Web site, which remain more visitors, and this is generally a good thing:-). Mentioned as I above, if you will see significant changes in the ranking, I would look elsewhere for the problems.
CDNs are overall good, as long as they are configured correctly. You can actually lead to a faster site, which we all know, Google examined.
