Add rel="nofollow" Attribute To URLs - Reduce Spam - Increase Pagerank
 

This little hack will edit all the URLs within posts and signatures and add a rel="nofollow" attribute to them.

This will do a number of things. First and most notably, it will reduce spammers because search engines will no longer follow these links. It will also stop your pagerank from leeking onto other sites. Also, some people say that adding nofollow to your URLs will increase your Pagerank. This is more of a matter of opinion, make up your own mind about it :p

1.0.0 - Released
1.1.0 - Added option - Change links in signatures

vbSEO users already have that but thanks anyway ..

Alot of people don't want to buy vBSEO so this is a nice free alternative :)

Google announced in early 2005 that hyperlinks with rel="nofollow" attribute[3] would not influence the link target's PageRank. In addition, the Yahoo and Windows Live search engines also respect this tag.[4]

How the attribute is being interpreted differs between the search engines. While some take it literally and do not follow the link to the page being linked to[citation needed], others still "follow" the link to find new web pages for indexing. In the latter case rel="nofollow" actually tells a search engine "Don't score this link" rather than "Don't follow this link." This differs from the meaning of nofollow as used within a robots meta tag, which does tell a search engine: "Do not follow any of the hyperlinks in the body of this document.".

Thanks for clarifying some stuff there. The pagerank thing is believed by some people, I was sceptical though :rolleyes:

thanks :) installed

Thanks! This will work well on my sites that don't have vBSEO installed :)

It doesn't stop any spiders or bots from following links.

Major search engines like Google, Yahoo, Ask, ect...wont follow these links.

No, it won't. It may stop spammers from benefitting as much from those links but it won't stop them from posting the spam.

"PR Leak" or "PR Bleed" is a persistent and longstanding myth, but it is nonetheless a myth. Your forum pages don't lose PageRank by linking to other pages.

Those people, whoever they are, would be totally wrong.

When spammers realise that you have nofollow links they will stop spamming you. So it reduces spam...

And there is such thing as PR leek. For example, iframes regularly leek PR. Although it's not benefitial to anyone.

Thanks installed.

nice mod, good idea for those not using vbseo already
but I'll have to agree, this mod shouldn't state that it will "stop spam"
I understand what you are saying, but many will just argue with this statement ;)

Is it good if i can use both? i have vbseo installed but this looks good to use too :)

Fair point, I changed it to reduce.

vBSEO can do this for you anyway :rolleyes:

installed , many thanks

Thanks Installed :up:

Forgive me for sounding daft, but I`m new here. How do I install a mod?

This one still works

Installed :) thanks

I have a quick question. Does anyone know if this mod will conflict with vbAnonymizor? Since both mods edit the links, I'm assuming there might be some conflicts.

It should be ok, however Ive not looked at the code of vbAnonymizor. So I can't guarantee anything. Its worth a try though.

go to your admincp, go down to manage products and download the xml file to your desktop and just choose that file and then upload, your all set

Thanks alot for you

Is it possible to only change links in posts and leave signatures alone? I like to allow some usergroups to get a benefit of the page rank but leave the spammers out.

Go into the plugin manager and edit the plugin named: add rel=nofollow" to urls

Then delete this line:

Save it and it will only change the URLs in posts and not signatures :)

Well, it does some how, many spams user posting to forum to get backlinks.
If we notify them that this forum is Nofollow. They may give up. :d

Thanks, downloaded and installed.

I liked this idea so I added an option to decide if you want to edit the signatures in vBulletin options.

Thanks ;)

Thanks :)
Mark As Installed & Nominated :)

Works perfectly so far. Marked as installed and nominated

Many thanks

first can you change rel = "nofollow" to external links only ?

second can you please add option to nofollow in Visitor Messages & Albums ?

thanks again

Thanks a lot for the product. I have installed the product, unfortunately nothing happened. Do I have to do anything other than importing the product?

Great suggestions. + 1 from me

Yep

in your AdminCP > Forum Options > rel="dofollow" Options >

Add rel="dofollow" to Signatures? (Choose yes)

If it doesn't work rebuild the links in your existing posts

you need to go to AdminCP > Maintenance > Update Counters > Rebuild Post Cache

Thanks Mongez. Actually 'DoFollow' means there should be no 'rel="nofollow"' attribute, right? I think
should be
Because the option page says 'DoFollow' and not 'NoFollow'. Anyways, thanks a lot for the plugin. It saved me a lot of time and worries :)

Yes you are right :)

but this is the title created by the Coder :D

don't worry all things is tine

only if the plugin doesn't work do what i tell you in my last reply :up:

regards

Great Plugin!

So why is the spam on all my forums getting worse and I have had a no-follow mod in place for over a year now?

That mod (and yes it still works on 3.8) allows me to specify external URL's that are not do not get the nofollow attribute to (eg to my other sites if a link is posted to them). I see nothing in this current mod that allows this (I stand to be corrected if someone can point this out), so will stick to the other one.
