Feedburner hack: how to get 2500 subscribers overnight (video)

Joop Dorresteijn, Contributing editor

Established blogs like ReadWriteWeb and Techcrunch proudly show a Feedburner chicklet that displays the sites popularity. But beware – since people are more likely to subscribe to a site with a bigger amount of readers, some sites manipulate the counter.

Every once and a while co-editor Patrick and I stumble on a shady looking website with a ton of readers. That made us wonder whether Feedburner is hackable. I’ve sacrificed my personal blog for a hacking experiment and the result; faking your subscriber count IS possible!

We found an easy way to hack Feedburner (Not the obvious hack that simply steals a chicklet from a popular site). Looking at the subscriber count at some sites, we’re not the first ones who found out, but we are the first ones to write it down. All it takes is an OPML file, a Netvibes Universe, and a good night’s sleep.

EDIT: While the hack still works, I am happy to tell you that Google and Netvibes are working on a solution to the problem. Steve Olechowski, co-founder Feedburner mailed me and said: “These things happen occasionally and are usually fixed in a couple of days”, he added that the feedburner counts do not influence advertisement measurement. Franck Mahon from Netvibes said: “We are working on a fix to filter out in the reporting the duplicates while still allowing people to add several instances of the widget to their startpage.” When things get fixed, it would be interesting to see the differences on some sites.

How to manipulate your Feedburner subscribers in two minutes


Feedburner hacked! on Vimeo.

Moral of the story is: everybody can have a lot of Feedburner readers, which makes the service questionable as a measurement of performance. It’s up to Google/Feedburner to fix things up.

Once they do this, it will be very interesting to see which blogs suddenly lose a bunch of subscribers…

I hope you like that post!

    There goes the value of my Feedreaders, if everyone can mass produce them, we will have hyperinflation on our back pretty soon. Nice trick though, I think I will sent out a bunch of emails tonight, than I can guarantee to double amount your amount of feed readers in a month for only 300 usd, anyone interested?

  9. By Eden on Aug 4, 2008

    So, I assume we can run some scripts or searches of NetVibes and find pages with thousands of subscriptions to the same feed? I’ve never used NetVibes so maybe it doesn’t work that way, but I’m going to try to find out. Sadly, it won’t load right now as the TechCrunch report apparently killed it.

    I wouldn’t recommend trying this. Google is certainly aware of the issue and could come down very hard on sites that have obviously jumped to several thousand users from just a handful. That said my Feedburner count goes up and down so much because of reporting problems with the system, I’m not even sure how they’d be able to tell. I wrote about the Feedburner Myth a while back on Sciencetext - http://www.sciencetext.com/the.....-myth.html

    [Reply]

    By Boris Veldhuijzen van Zanten on August 4th, 2008:

    Since this is an obvious bug in Netvibes & Feedburner I would guess that Google would simply fix the bug instead of punish those abusing it. But we will probably find out soon…

    By David Bradley on August 4th, 2008:

    Hi,

    In my point of view it’s more a netvibes problem than a feedburner one. Feedburner rely on the number of subscribers given by netvibes.

    So the best is to wait for a fix from netvibes (hope it will come soon).

    It is not a Feedburner hack, but a Netvibes hack, because this is Netvibes who provides the number of subscribers in the HTTP logs…

  23. By Arun on Aug 5, 2008

    This is an interesting hack who ever got hacked whether it is feedburner or netvibes, it is quite sure that some blogs are using this technique to show fake number of readers. If this issue gets tackled then lots of blogs are going to lose their readers. Lets see what happens.

    I am happy to announce that Google and Netvibes are working on a solution together. Steve Olechowski, co-founder Feedburner mailed me and said: “These things happen occasionally and are usually fixed in a couple of days. We have a number of facilities in our system to quickly tune our algorithms to provide publishers with an understanding of their audience. It’s worth noting that we don’t use subscriber numbers for measurement with advertisers, we use a number of other measures we collect.”

    Franck Mahon from Netvibes said “We are working on a fix to filter out in the reporting the duplicates while still allowing people to add several instances of the widget to their startpage.”
