I would like to use a naked domain instead of one with a sub domain but am worried about some potential issues down the line.

It is an ecommerce site so if the site grows then a content delivery network (CDN) will most likely be used. I believe you cant use a CNAME on a root domain. Would the best solution be to use a separate external domain e.g. staticexample.com? If we did use an external domain, would that affect images in search results?

  • You can use a CNAME to alias a domain name to a providers sub-domain. People do this all day every day. No worries. Cheers!!

  • Using an external domain does not affect your image SERPS and in fact, most companies don't brand their CDNS and just use the ones provided by their CDN provider. Feb 28 '18 at 1:57
  • Ok thanks. So from what I've researched the only disadvantage of having a "naked" domain would be that cookies get sent to all sub domains, we're not planing on using a sub domain so this isn't an issue. Is there anything else i should be aware of?

  • @closetnoc a CNAME can not exist at apex of zone, hence for the "naked" domain. This is per DNS specifications. Various providers offer various workarounds for that. Feb 28 '18 at 15:33
  • @PatrickMevzek Not trying to snotty. Honest. My statement was simple. A CNAME can be used to alias a domain name to a providers sub-domain. This is not only factual, but something I did automatically as a part of my hosting business daily for decades. I was one the the first registered ISPs, web hosts, represented U.S. Robtics at ISPONE, was a core network consultant to all the major telecoms and backbone providers, etc. My simple statement is indeed factual. I, however, am not sure what you are trying to say. (Said with kindness.) Cheers!!

You can either use an external domain or subdomain of your main domain with the same results. The only think you have to take into account is that they must be cookieless and fast in order to work propertly as your own CDN.

In the future you will be able to switch easily to a professional CDN in both situations.
