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:

Quote:

<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

Quote:

<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."

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.

I will install this on monday.

Good job kall, will work great

~Curt

I'm not going to install this as my forum doesn't need it, microscopic in size compared to the majority - but just thought I would post my support for an excellent effort!

Hook bbcode_create

PHP Code:


		
			
$this->tag_list['no_option']['url']['callback'] = 'handle_external';

$this->tag_list['no_option']['url']['external_callback'] = 'handle_bbcode_url_relnofollow';

$this->tag_list['option']['url']['callback'] = 'handle_external';

$this->tag_list['option']['url']['external_callback'] = 'handle_bbcode_url_relnofollow';



if (!function_exists('handle_bbcode_url_relnofollow'))

{

    function handle_bbcode_url_relnofollow(&$parser, $text, $link)

    {

        global $post;

        // Excempt Mods+ and Users with mor then 50 Posts

        $parsedurl = $parser->handle_bbcode_url($text, $link);

        if (is_member_of($post, 5, 6, 7) OR $post['posts'] > 50)

        {

            return $parsedurl;

        }

        else

        {

            return str_replace('href="', 'rel="nofollow" href="', $parsedurl); 

        }

    }

}

Or (simpler, but might affect mor then just [url])
Hook: bbcode_parse_complete

PHP Code:


		
			
global $post;

if (!is_member_of($post, 5, 6, 7) AND !($post['posts'] > 50))

{

    $text = str_replace('href="', 'rel="nofollow" href="', $text);

}

This seems to have conflicts with the "PM group leader on join request" plugin. At least it did with mine. :(

would the work with grapping of the newsgroup and from mailinglist? Would the plugin work with the nntp newsgroup pulling.

I can't see how .. all this does is add an attribute to the href of a link.. can you please explain?

        {

            return str_replace('href="', 'rel="nofollow" href="', $parsedurl); 

        }

    }

}

For some reason I have no idea whatsoever how to apply this code. Is this basically a replacement in class_bbcode.php for what Kall originally posted?

You can just upload the attached .xml now, thanks to Kirby. :)

(Could a Mod move this to the Plugins Forum? Ta.)

The plugin is not working for me in 3.5 RC 2. Anyone else have any success with it?

Working fine for me. I have min posts set to 50 (51 promotes members to another usergroup) and several usergroups exempted.

Look at the signature for this user f.ex. as opposed to the moderator posting on that thread. Here is a user with 50 posts.

(this is where "View Selection Source" in Firefox comes in handy)

I am.

I downloaded it from my plugin system.

Will this make ALL links in forum posts get the attribute? Because it would be nice if links posted by admins or mods would not get it since they often link to other pages within our own site.

Let's look at the bit in the first post that controls who has their posts/signatures "nofollow"'ed:

PHP Code:


		
			
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

Might this have something to do with vb's parsed post caching?

One of the best hack ideas I have seen for a while. Very good job! :)

I'd love this for v3.0.9. I can't upgrade to 3.5 and the functions_bbcodeparse.php file is much different.

Great hack.. "Installs"

Then look at the 3.0.x hacks in my profile. ;)

Thanks for a great hack

Ya know I kinda have mixed feelings on this idea ... personally I would like links in my users sigs to be followed, as some of my users run there own sites and would like to get them ranked well in search engines. I can`t see it causes me any problems, and helps the people who make my site work ..

The ability to choose which forums it stops would be nice .... eg. If I have a forum for people to post links like this, then I would like to disable this on that particular forum.. Hope that makes sense LOL

So, any way to do this?

Very nice modification kall :)

Chris

Do this work for Version 3.5.1?
Cause I installed the plugin but nothing happens.

This worked great for me in 3.5.1 Except for the homepage URL located in their profile. Any way to add this there?

I installed this mod and it wouldn't display any threads after I did. Not sure what went wrong with it...

I would love to see a whitelist exclusion for certain URLs. vBSEO lets you specify, say, smugmug.com, google.com, and vbulletin.com as exclusions so the rel="nofollow" attribute.

I ended up not being able to use vBSEO, so I'm looking for a nofollow plugin to replace it.

is it workin on 3.5.3 ?

yes i have 3.5.3 and i dont know if this working, can u tell me also, i want to all group have The Nofollow Attribute

working for me on 3.5.3

is it possible to make this script work only in few forums ?
i dont want to block links with "rel=nofollow" in all forums

thanks.

Hmm, I used the plugin system to upload this hack on a 3.5.3 board but it doesn't seem to be working? Anyone know why? Thanks

i have this same problem, i am using vbulletin 3.5.3
technically hack should only add rel=nofollow tag to content in posts and users signatures without touching other parts of the forum..

but check this, there are many other areas where the rel=nofollow should not be added:

Code:

<table cellpadding="6" cellspacing="0" border="0" width="100%" class="page" align="center">

<tr>

        

        

        <td class="tfoot" align="right" width="100%">

                <div class="smallfont">

                        <strong>

                                <a href="sendmessage.php" rel="nofollow">Contact Us</a> -

                                <a href="http://www.officehelp.in">Office Help</a> -

                                <a href="admincp/index.php">Admin</a> -

                                <a href="modcp/index.php">Mod</a> -

                                <a href="archive/index.php">Archive</a> -

                                

                                <a href="#top" onclick="self.scrollTo(0, 0); return false;">Top</a>

                        </strong>

                </div>

        </td>

</tr>

</table>

Am i missing something ? or can someone guide for installing this plugin perfectly, seems to be a very good plugin/addon.

thanks.

Problem 2:
Even after disabling the plugin from plugin manager, rel-nofollow still appears for internal forum links.. :surprised:

Look in your templates. Those are all there by VB default.

thanks welo.
i was not aware about this :)

problem 2 solved - courtesy welo
problem 1 - waiting for a solution.

Yeah, they did that to prevent unnecessary spidering of 'Post Reply' buttons and stuff like that, along with somewhat controlling the silent spam that sometimes creeps into memberslists in signatures etc.

So.. problem 1... does it occur if you disable the plugin?

If so, it is a vB default thing as per welo's post above this one.
