I spotted the following interesting situation and I notice this for several domains, so this is not 1 time occurrence
1. I input a keyword related to "online casinos" in my country language into google search
2. search results open like normally and on top of the page I see adwords results like usually
3. In adwords results I see a russian domain (all of the domains I spotted are russian in this case .ru) with russian title text (my country is in EU but we do not write in cyrilic)
4. When I click the link I am redirected to online casino
5. most importantly, when I open the domain from the ad title/url a legitimate online store opens, like dog food store or clothes store depending on the url - that does not make any sense
6. I also saw the same ad with english title, but never in the language of my country
here is a screenshot from google serp http://prntscr.com/l06749
So what is happening here? Someone hacked the legitimate online store adwords account? Even if they would, how would the gambling ad go through approval at adwords? I thought gambling is restricted in adwords. Why would someone target a Russian text ad in my country? Even english one does not make any sense.
I forgot to add that my computer is not hacked and is not injecting anything in my serps, my friends see the same ads
It is cloaking. The online store you see is safe page ( google see this, and thinks it is legit landingpage, so they approve ad ).
The cloaking filter google crawlers and reviewers to this safe page, and other traffic redirect to money page ( online casino in this case ).
I do not understand how this could work, how could google approve an ad for "online gambling" keyword with a landing page being a dog food store
It's as qkvaterpipe said.
The people running the ad are using a cloaker.
That means that they show different sites to the Google reviewers and to real users.
In this case they show a normal online store to the reviewers to get the ad approved and the normal users get redirected to the casino.
A cloaker is a software that recognizes ad reviewers and trafficsources by different parameters.
That way you can run stuff that usually is not allowed to run.
It's cloaking (twinaxe and qkvaterpipe already explained it) but there are many more use cases of a cloaker
.
And discussion on "what is cloaking?" is not good in an open forum.

Yes, as it was already pointed out, look pretty much like cloaking.
With this technique they can obey the rules and display ads they want.
This falls under "blackhat" tactics.
It's against the ad network policy and terms and that's why we openly do not discuss this type of things.
Some time has passed and I feel the need to add to this post, I feel that you have not entirely understood my point.
I perfectly understand what cloaking is and how it works. I cloak since 1998 on Altavista, when altavista was the main search engine and there was no google (I suspect not many users on this forum know what Altavista was), afterwards I cloaked for google since around 2001, yes I know this is cloaking for SEO purposes, now I cloak for facebook with good results. My point here is that the ads I showed in my first post are located on *policy restricted gambling keywords*, meaning that you cannot add any ads on these keywords unless you go through gambling approval process through google.
