Lander protection

Our tracker has special facilities to protect landings against the direct entry. At that, there is no need to keep your landings on same server with the tracker. The protection base is checking of the time gap between the click is passing through the tracker and landing opening. In case too much time is used (5 minutes as standard), there is to be opened an empty page instead of landing. The IP and User-agent matching is checked as well.

How to use?

1) Move to the tracker settings and make a code copy from the LP Protect:

This code is also available in each edit window of the landing.
2) Paste it into the begin of your landing's code.
Important! Your landing file should have .php extension
3) Move to the landing's settings and add LP Key token to the URL in order to provide the key to the landing.

Now your landing can not be opened without the click through Campaign URL.

White landing page instead of blank page

By default LP Protect shows blank page. If you want to change this behavior and show “white” landing page instead – you can use this code:

                            
                                <?php 
                                    $key="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
                                    $a=@$_GET["lpkey"];
                                    $b=substr($a,0,2).substr($a,4,2).substr($a,8,2).substr($a,12,2).substr($a,16,2);
                                    $c=substr($a,2,2).substr($a,6,2).substr($a,10,2).substr($a,14,2);
                                    $d=md5($key.$_SERVER["REMOTE_ADDR"].$_SERVER["HTTP_USER_AGENT"].$b);
                                    $d=substr($d,2,2).substr($d,7,2).substr($d,12,2).substr($d,24,2);
                                    if(time()>$b || $d!==$c){
                                    ?>
                                        <!DOCTYPE html>
                                        <html>
                                        <head>
                                            <title>White page</title>
                                        </head>
                                        <body>
                                        </body>
                                        </html>
                                    <?php
                                    }else{
                                    ?>
                                        <!DOCTYPE html>
                                        <html>
                                        <head>
                                            <title>Black page</title>
                                        </head>
                                        <body>
                                            <a href="https://domain.com/click.php?lp=1">Click to offer</a>
                                        </body>
                                        </html>
                                    <?php
                                    }
                                ?>
                            
                        

Replace xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx with your LP Key and https://domain.com with campaign domain.
Now you don't have to hide referer because it will always lead to “white” landing page.
