i agree with the CTR is a ranking factor, but not as much as you expected. #5 move to #1 ? i dont think so .. unless its super low competition..
the service is looks good only i think on low search volume
because for example if the US click cost 0.50$ , then i have 300,000 search volume,then i should pay 150k$?? thats ridiculous
and i saw this on FAQ
Q: How long do visitors stay on my site?
A: Randomly between 20-40 seconds.
this is a great bouncerate and timespent on your website
google monitor this too!!
20-40 seconds is unnatural, most of my site atleast have a minimum of 5 minutes
even without using a google analytics google can see bouncerate and timespent on website in many many ways..
end rant...
