Hi Guys,
question here
i set up my campaign in zeropark and using
this is the stats below :

so i got 2000ish visit in unknown OS without any single click, this unknown OS could drain my budget easily.
my question :
1. is this bot traffic?
2. how to avoid that?
thanks!
possibly. check ips to see if its all from just a few.

yes, well the top one at least

Try implement Caurmnn, Ksoder or Matuloo's bot trapper methods as follows;
Below is one option(1) for you.

Another option(2) is as follows;
create a multi sequential landing page campaign
1st page: Blank Javascript page that auto redirects in under a few milliseconds to your desired landing page
On the page you can add a small hyper link to a dead page which can only be clicked on by a bot as the page redirect too fast for a human to react to click.
2nd page: Add invisible small image/s on your presell page that only a bot can click upon as a user's eye cannot see it.
When you use option 2 in your campaign to see if bots are there you will see a percentage drop off from the your 1st page.
Example
Page1 has a 60% CTR meaning 40% of your traffic did not go past the auto redirect as a lot bots tend to not be able to read javascript.
For more in dept check out Caurmen's stuff on bots which is detailed.
Hope that get you off in the right direction.
