I have a substantial Spanish-language section, and I was wondering whether it would be better to split it off into another domain rather than just keeping it in a folder. How smart IS google at indexing and at AdSense targeting?
adsense can understand that your content . i also suggest you to use section targeting for your all web pages
AdSense did tell me to use a different domain - I wasn't expecting an answer, but I got one. Switching to a new domain immediately improved the accuracy of the results, which surprised me, because I thought Google was smarter than that! When you say "section targeting" do you mean the thing where you put in tags that say "this is important, rather than this"?
Subdomain would have worked but presented no real advantage over using a domain I had anyway (.org instead of .com) ... still required a separate folder and user etc the way my system is set up. Good idea - it was my first choice too.
You will get targeted ads for sure irrespective of whether its a subdomain or another section of thesame site.
I have indeed been getting nicely targeted ads now that it's not just in a folder. However - eCPM is pretty low, about 1/4 of the same site in English. Is it simply a smaller, less competitive market? CTR is only a little lower. Are there better alternatives to AdSense for Spanish language sites?
