For a period of six months my web logs recorded over 189 suspicious click throughs (same IP address)approx 1 per day every day.
Basically i only have 5 keywords as my business has a very narrow target range. also my website would only be useful to someone to find out what i do then call me for help. so no need for this person to visit everyday.
Also the keywords i use are highly competitive so the value for them can sometimes be as high as £3-5 pounds so 189 dodgy click throughs is about a third of my total google budget. and could be worth in the region of over £500- 800 GBP.
This was reported to google and after a little prompting they decided to investigate, below is the reply i recieved.
Thanks for the email. The clicks some keywords appear to be invalid. We have applied a £14 to your account.
Thanks Google next time i spend upwards of £3k annually on your service i'll fxxking well make sure who i'm dealing with.
