My Review:
First I want to mention that in order to test this traffic along with GA I was using our special tool that tracks mouse moves, clicks, key strokes and records every visit as a video. Without special software and deep analytics it's impossible to study and evaluate traffic.
So here's my review:
1. All traffic source was shown as it came from Google and from the keyword that I provided (good)
2. All traffic came from locations requested (US/UK/CA)
3. Site was getting 1 to 5 page views per visit
4. 95% of the visitors had Chrome browser the rest had, Firefox, IE, Opera
5. Time per visit 1 sec - 57 sec
6. Users do not scroll
7. Usually page views per user equals to user clicks
Pros:
- Even though traffic was tested not on AdSense site, I think its AdSense safe as it does not click on ads.
- It may lower your bounce rate since most of the lists had 2+ page views.
Cons:
- It is suspicious that most of the users had Chrome. Of course campaign may target only specific browser, but I think its just easier to manipulate results to show Chrome rather than e.g. Safari
- I am not sure why there was no page scrolls, usually user always scroll down even if he got on site accidentally
- There were no ad clicks, users clicked to where the cursor was after the page loaded, so if my site would have different layout I doubt I would have that many page views as it would have clicked on a empty area
- There was almost no mouse moves
- There was no key strokes
Conclusion:
This may be a good traffic for specific reasons that you may have and for the price its being offered it may be a good deal, but I doubt that you'd be able to bank with it.
