While looking at the content access statistics in Google Analytics, I’ve noticed that a few of them access a page with the URL /eyeblaster/addineyev2.html. Since I was pretty sure I didn’t have such a page I first thought that my site might have been hacked and checked this page. It led me to the 404 error page. So this URL didn’t exist but some of my visitors were redirected to it. The traffic to this page was not so high (never more than 5 page views a day) but I could see that this added up to 25 page views since mid of February.
Next step was to find out where these visitors were coming from. The navigation summary in Google Analytics for this page looks like this:
So half of the visitors came from a previous page and half from outside. The distribution of previous pages was pretty random, so it is definitely not related to specific pages:
But actually the important most visitors leave my blog once redirected. Googling for this issue, I found a Google support page:
If you are trafficking an EyeBlaster Flash creative as a 3rd-party tag, you will need to put the addineyev2.html file to www.example.com/eyeblaster/addineyev2.html
<HTML> <HEAD> </HEAD> <BODY style=margin:0;padding:0> <SCRIPT src="http://ds.eyeblaster.com/BurstingScript/addineye.js"> </script> </BODY> </HTML>
If you add this HTML page, you should also make sense to prevent search engines from indexing it by adding the following to your robots.txt:
Disallow: /eyeblaster Disallow: /addineyeV2.html
Or by adding the following metatag to the head section of this HTML page:
<meta name="robots" content="noindex" />
To block this network, you have to go to Adsense, click on Allow & block ads, type “mediamind” in the search box. You’ll see something like this:
Then click on the left side button for each of these networks to block them:
Now you shouldn’t get these ads which end up redirecting your users to this non-existing HTML page and you’ll display ads from networks which behave better. I’m suspecting that other networks might also be using this script, so I’ll have to monitor this and find out which other ad networks I’ll have to block.
