I posted previously about bizarre ads in Russian suddenly showing up on my site and killing my earnings (see http://forums.digitalpoint.com/showthread.php?t=29632). It's been 12 days and the problem isn't fixed. Emails from Adsense support have been slow (3 day response time) and not useful (the latest saying the problem is fixed - it is not). So today I do a site:mysite.com at google.com and then click on the Cached link for my main page. And guess what I see - a website in Russian. It's not my site, not my domain, but it has my domain name as the title of the site. Is this very strange or what? How did Google get this screwed up?
I guess someone have 301'd or 302'd your website... That's a big Google flaw... If you know who is the offender you can block the domain via http_referer to some dummy page or to 127.0.0.1 for example... That should fix it...
Interesting. I have a similar problem. My "bad" ads are all in English, but I'm getting 30% to 60% totally off topic ads. Google says the problem was fixed a month ago, and it is not. When I go to the cached pages [which in my case are for my site], which are typically from March and April, all the ads there are totally on topic.
@aeiouy, thanks for the PM and offer. You said maybe someone is trying to hijack my site. How does that work? How are they able to get Google to index their page for my domain?
Thanks for that link. I did a quick read through. This is of serious concern. If this is what happened then not only did my page get displaced in the SERPs but I lost Adsense revenue as a result because the hijacker was a Russian language page and Adsense got fooled into serving Russian language ads. Late breaking news: I just received an email from Adsense support. Said they are "fairly stumped". They know that Google incorrectly indexed the Russian site (apparently hijacked, although they didn't call it that) but they reindexed my site and their internal systems now indicate that they are serving English language ads. And they are seeing relevant ads in English when they view the site. But I am not. I am still seeing Russian ads, regardless of browser or computer I use. And when I preview ads using the DP tool it shows only ads in Russian.
Interesting link Spencer, this section explains why banning referrers is no good: http://clsc.net/research/google-302-page-hijack.htm#009
Received another email from Adsense support. They say their crawlers are having trouble accessing my site and suggest I check my DNS settings. What am I looking for? All the settings are the same as my other sites that don't seem to have a problem.
