Mobile SEO

Hi guys, I want to ask you something related to mobile SEO, my company wants to migrate our mobile site, now we have separate URLs, site.com and m.site.com we want to change this for a dynamic serving approach so we can have just one URL so that can help us with SEO, the thing is I read on google that we should put the vary HTTP header, but our it teams said that as we are using Akamai they do not recommend using the Vary header because it could have conflicts with the cache, my question is if we don`t use the Vary header google may have some troubles identifying our content for mobile device or desktop? Thank you very much for your help!!

  • Neeraj Pandey: Yes it will not be a clear signal to se if you don't use this. In akamai what is the problem in setting up HTTP header vary? Here it doesn't have anything with cache but it simply tells that on the basis of user agent out pages are changed but for each user agent you can maintain the cache... Still would like some experts to suggest you
  • Suraj Gadage:  ;Your IT team is absolutely right. CDNs like Akamai usually have problems with Vary HTTP header in terms of caching or serving the right content. Google says that the problem over the Vary HTTP header is with the CDNs and not their guidelines. However, I found a mixed responses on this problem. Below mentioned thread on Akamai community says that caching works as expected by vary header.



    Other hand I found someone from Akamai mentioning a workaround on Google Group for using Vary HTTP header.



    Hope this helps your IT team to fix the problem.
