A big challenge for a number of companies is updating the XML files on their servers. We have had some clients where their IT teams need 45 days to update the files and another client’s files are 6 GB in size making traditional uploads a problem and giving direct access as a security risk. The answer is to create a dedicated location either with a subdomain or a dedicated site to post the files directly from HREFLang Builder and then use cross-domain verification protocols to connect the sites. This completely eliminates the need for any handling of the files outside of the tool. For more information on this feature please review our Setting up Cross Domain Hosting.
