I Started to make a website that provide a shortlink with ads and then pay the publisher , but for advertiser they only want real people to see their persuasive ads , so my problem is how to know the viewer is real people and high quality enough to make the counter count them so i can give reward to the publisher ,
sorry if you don't understand my english is bad
THANKYOU VERY MUCH
There is some small REST API doing great IP verification returning a score for the IP you send, example :
$ip = $_SERVER['REMOTE_ADDR'] ; // your user IP
$checkIp = file_get_contents('http://check.getipintel.net/check.php?ip='.$ip.'&contact=mail@example.com') ;
// don't forget to put a real e-mail
if ($checkIp <=0.95) {
// this user is not a bot !
// do something here
}
Then you can save the result in a session or a cookie so you don't have to call API on every page. I use to work with http://getipintel.net/ but based on the same idea you can use google invisible captcha.
