I have had a similar problem with one of my web sites. In my case, I am fairly certain that it is was a fake traffic based on three things.
#1 - My Adsense CTR for that page was exactly 10%. (That's not very close to my average.)
#2 - None of the visitors went to any other pages.
#3 - Visitors came in six minutes intervals.
What you should do is download and analyze your raw access logs. Look to see if any of the visitors did anything besides visit page abc.html. Also, look at the time intervals between each visit.
Having visitors come exactly six minutes apart from one search engine using the same exact same search phrase for five hours straight is not normal behavior.
Also, make a quick list of 25-50 suspicious IP numbers and try to determine where they are originate from. In my case, I traced many of the IP numbers back to open proxies.
If you have access to .htaccess files, you can ban the traffic by IP address or by browser ID or by referring page. That should handle your bandwidth concerns.
P.S. If the IP addresses and browser IDs are diverse, you should consider the possibility that the traffic really is genuine. Maybe some high-traffic site happened to link to the Google search for this phrase.
the attacks were exactly 5 times a minute, continuously for 7 hours
the visitor did not go beyond a single page
the phrase is the name of Turkish lady, I dont think any humans are searching continuously for the information
I had adsense on that page, when I realised that someone was attacking the page, I removed the page to stop bandwidth usage.
Now I can only hope that i am not banned from Adsense
You might want to contact Google proactively if you haven't already done so. Normally a spider wouldn't generate AdSEnse impressions or clicks, but it's possible.
