i found this on a website. This is what made me want to ask this question here

I suppose you read that here, http://www.webconfs.com/importance-o...-article-5.php

That info is outdated, after Google came out with Panda and Penguin updates, points for backlinks changed.

This is the js for that linkback mod..it's from vBSEO

Here is the link to the js file: http://www.aquariumforum.com/clientscript/vbseo_ajax.js

But is it even necessary anymore?

No not at all ... you would be doing the same thing if you tweet a post or thread or use facebook's like system ... linkbacks/backlinks are no longer rated and deemed important like they once used to be at all .. which is why "I" don't even bother when other websites want to exchange "linkbacks" with me lol ..

Carp I usually never try to tell anyone that what they are looking for us pointless, but in this case you really are not going to gain anything from adding this to your site ..what you will be adding though is some worthless js that may negatively impact your site's load times and performance overall for nothing ...

That's what I thought. Ay one point, 3+ years ago, it was good, but it is no longer needed.

Here .... read this about backlinks by google .... I actually try my hardest to avoid any kind of backlinking on my site ...

Yeah...there was just so much shady stuff going on with backlinks that google caught on to it ...now even if you are doing it in a good way you still risk being penalized ...

Backlinks can do more harm than good depending on the site that links back. You should be very selective with who you allow linking. This is why every week I spend hours doing link research and doing link disavows for clients. Linkbacks with high risk will hurt page rank badly and some times even get you a penalty.

All the time I'm getting requests now to remove completely legitimate links my users have posted over the years in my forum. Funny thing: as soon as I request compensation for my work in finding and removing those links no one seems to be interested anymore :)

HaHaHa, I am going to have to remember that one. :)
