Moveable Type Backlink Exploit

Do you want free backlinks? Does the Pope shit in the woods?

Boogybonbon has found a way to exploit the preview comment form to create backlinks from Movable type blogs.

From the post, MovableType preview button good for back links:

As long as the blog is not a MovableType 3.2/3.x the blog will give a nice URL that you can publish into a ping list and get indexed for back links. This is because the MovableType 3.x uses JavaScript to convert tags into a preview comment field and as we all know search engines cant see that.

Needles to say it only took me about 15 minutes to find 6 blogs with PR 5-8 and process the forms over to GET then post the URL’s into a couple ping sites.

Here’s how it works:

The preview comment button on movable type blogs uses the POST method but search engines require the GET method to index a URL. So, what you need to do is:

1. Download the firefox extension webmaster tools to convert the POST forms to GET forms.

2. Find Movable type blogs.

3. Open The “preview Comment” in a new window.

4. Convert the POST Form to a GET Form like this:

5. Fill out comment however you like.

6. Press preview comment.

7. Instead of producing a url like this:

it will produce a URL like this (images used for formating purposes):

The links on the produced pages are NOT nofollow.

8. Now, you may want to use a service like tinyurl or a redirect to hide what you are doing (not required)

9. Ping that URL to the Search Engines in splog posts, guestbooks, or however you think best.

Pretty freaking cool, huh?

I’d like to add a quick reminder that you need sign up for the SEO poker Tournament by tuesday and email me your pacific poker username and website URL.

    Dude, that is a really sweet hack!

  2. scottj says:

    Oh, and by the way, I have found a Movable Type 3.2 blog that this works on, so there may be others as well.

    Great post! Thank you.

    google dork: “inurl:mt-comments”

    For ex has pr 5. You’ll find more sites with bigger pr if you’re clever.

  5. nnet says:

    Will it work on pre MT 3.0 versions as well?

  6. RisK says:

    haha, lucky me. I’ve disabled this feature a long time a go. that’s because MT has so many template files, and even the comment preview has it own template file. so to cut down design time, I choose to disable this feature.

    then again, it’s probably just me. thanks for tips btw…

  7. sztojka says:

    it’ll work anywhere if you can make a comment preview as anonymous

  8. IrishWonder says:

    next thing likely to happen now is MT fixing the bloody thing so you’ve just successfully killed this for everyone

  9. nnet says:

    can we ping using a service like Pingomatic or a we better off posting the link somewhere?

  10. scottj says:


    You’re right. SixApart will fix this one ASAP. The catch is that for the fix to really take effect, people have to upgrade their blog software first.

    Thanks for sharing the technique. I have a question: Using this are we able to pass any pagerank to our pages. Or is it just for a quick indexing of the site?

  12. QuadsZilla says:

    It will pass pagerank if the created page obtains page rank.

    thanx 🙂
