Apply "rel=nofollow" attribute to all parsed URLs

In the first cooperative move for nearly ten years, the major search engines have unveiled a new indexing command for web authors that they all recognize, one that they hope will help reduce the link and comment spam that plagues many web sites....due to removing the point of doing it in the first place.

The new "nofollow" attribute that can be associated with links was originated as an idea by Google in late 2004 and MSN and Yahoo, as well as major blogging vendors have jumped onboard.

The Nofollow Attribute

The new attribute is called "nofollow" with rel="nofollow" being the format inserted within an anchor tag.
When added to any link, it will effectively serve as a flag to tell the search engines that the link has not been explictly approved by the site owner, and therefore "not follow" it, or not use the referring page's (on your site) Page Rank in any way.

For example, this is how the HTML markup for an ordinary link might look:

<a href="http://www.somedomain.com/page.html">My forums are the best lol lol lol click here!!</a>

This is how the link would look after the nofollow attribute has been added, with the attribute portion shown in bold

<a href="http://www.somedomain.com/page.html" rel="nofollow">My forums are the best lol lol lol click here!!</a>

Once added, the search engines supporting the attribute will understand that the link has not been approved by the site owner.

Think of it as a way to flag to them, "I didn't post this link -- someone else did, don't associate me with it."

3. NOT count the anchor text in determining what terms the page being linked to is relevant for.

The site that is being linked to will gain nothing from the link, so the whole point of doing it in the first place is removed.

This will affect URLs in posts, as well as signatures...anything that goes through the bbcodeparse function as far as I can tell/guess, and will work recursively, or whatever the word is that means 'it will affect all existing posts and signatures'...or it did for me anyway.

To change the conditional number of posts, alter

PHP Code:

OR $post['posts'] > 50) 


to whatever you like.

I can't see how this could be done as a plugin, but if anyone wants to point out how, that would be nicer....YAY Kirby!

Now all you need to do is unzip the attached file, upload the plugin using your Admin CP - Plugin System - Plugin Manager!

Relax, safe in the knowledge that spammers linking from your site are doing so for no reason whatsoever.

To remove the old version:

File to modify: 1

1/ Open your includes/class_bbcode.php file

Find:

PHP Code:

        // standard URL hyperlink
        //return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";

        global $post;

if (is_member_of($post, 6) //Admins are exempt
OR is_member_of($post, 5) //Mods are exempt
OR is_member_of($post, 7) //SuperMods are exempt
OR $post['posts'] > 50) // People with over 50 posts are exempt
    {
    // standard URL hyperlink
    return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
    }
    else
    {
     return "<a href=\"$rightlink\" rel=\"nofollow\" target=\"_blank\">$text</a>";
    }
    } 


Replace with:

PHP Code:

// standard URL hyperlink
        return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
    } 


2/ Save and Upload.

thanks.

Is this possible? I didn't see an answer, so my guss iss no but I figued it was worth asking again

[Zia]

hello..

been looking for it for long time....


we are on vb 3.5.4 ?
does it works on 3.5.4 ?
like all of our posted image/sigs hosted on imageshack or photobucket...

Andres also posted an modification at #5 post
https://vborg.vbsupport.ru/showpost....74&postcount=5

which 1 is for what? which one we should install?

[Nick0r]

Kall, would there be a simple of way of making it so that rel=nofollow is _not_ added to internal links (e.g to the site the forum is on).

[athloni]

Thanks for the hack.

I would like this too....

Hello,

What part of the code would I remove to make it so that all links in posts and signatures have the no follow tag, and not exept user groups or people with certain number of posts??

Also can someone confirm that this only rewrites post urls and signature urls? I read a few posts on here stating that the script was rewriting many URLs including inbound links.

-Griffe

[kall]

How could a script rewrite INBOUND links?

Anyway. Take this out,

PHP Code:

OR is_member_of($post, 5) //Mods are exempt
OR is_member_of($post, 7) //SuperMods are exempt
OR $post['posts'] > 50) // People with over 50 posts are exempt 


Change

PHP Code:

if (is_member_of($post, 6) //Admins are exempt 


to this:

PHP Code:

if (is_member_of($post, 666) //Fake usergroup is exempt 


[meissenation]

Newbish question, but has to do with the linking. When someone posts a link in their signature, does it still work the same way as someone that posts a link in a reply? Would be an interesting way to stop someone from gaining rank just by putting links in their signatures.

This was installed on 3.5.4 and the link URL posted doesn't show " rel="nofollow">

What can be done?

Greg

[kall]

Who posted it? If it was you, and you are an admin (or it was posted by someone with over 50 posts, or a mod or supermod) it wont have the nofollow.

Is the plugin active?

[Treasure Quest]

I posted this link as a test user:
http://www.treasurequestxlt.com/comm...ead.php?t=5246

The plugin is active and the The 50 post minimum was removed.
I want all links from members to be No Follow no matter how many posts they have.

Oh, will this mod also make old links posted no follow?

Thanks

Greg
