I've been analysing one of my competitor's sites, they are setting up a new one that I've luckily found and are building links as we speak. The sourcecode shows that a high DR link has this:
* Revive Adserver Asynchronous JS Tag
* - Generated with Revive Adserver v3.2.2
<ins data-revive-zoneid="4" data-revive-target="_blank" data-revive-block="1" data-revive-id="XXXXX"></ins>
<script async src="//soso-aha.de/www/delivery/asyncjs.php"></script>
<a href="competitor.com" rel="nofollow">Their Keyword</a><br />
At first I thought this was a hacked link similar to SAPE but it doesn't have the appearance of it on the website. It fits right into the sourcecode neatly, as if the webmaster intended to integrate it. Going down the path of looking up this strange soso-ada.de domain (reverse lookups etc) it looks like a hosted solution of this "Revive" advertising programme:https://www.revive-adserver.com/
I thought this kind of thing was a bit 2009. Have I missed something, does anyone use it? I'm trying to join it.
About 25% of my competitors links seem to be generated through this. They are high authority domains, I don't think they are hacked. However if it's a link exchange then the competitor has zero such links on his site. So maybe it is SAPE after all... Is there a way to tell?
