post a new message with length longer than the number you set in "Min Post Length" option. select and copy the content of the post. paste it into notepad or your editor or your blog. you will see a backlink there.

Well I copied an old thread and pasted in a test thread. But the links are not hidden.
There are those links visible, like: "source: name of the forum and link"
edit: Opps, that's how it works, right?

so it works. it meant to be visible anywhere except in the original post.

I see,
last question: where can I change the "source" word to my language? I searched in templates, phrases and xml file. But couldnt find

search for phrase variable named "copyright_source"

Ok, thanks...

Good point.

Here is an in-dept article that exculpates the addon from any black-hat or even grey-hat SEO techniques.

Enjoy! :)

I know this is not meant for vb 3.7.4 but I tried it anyway and got this error:

I've read the articles before i created this mod. I think what Matt said support my idea. You can use hidden text, just not too much. that's why there are options for you to decide in which posts should the links inserted and how many of them.

As i mentioned, this mod act the same way your vbulletin popup menus do. if you think this will do hurt to SEO, maybe you should disable your popup menus either? and i forgot to tell, the back links will not be inserted if the pages are requested by bots. Yes, this is some kind of cloacking, but the vbulletin system itself cloacking the popup menus too by default.

I have implement a lot of so called grey-hat SEO techniques on my own site, and they never hurt my ranking. My attitude toward these techniques is simple: do what is good to users.

proably you have downloaded the previous uploaded file. plz try to download it again. it works for the version 3.6.8 afterward.

or open the plugin "Insert Copyright - Insert Text"

Replace All
