SEOvB - Link Canonicalization for vBulletin Stop Duplicate Content NOW!
Developer Last Online: May 2015
Squash vBulletin Duplicate Content Completely with Canonical URL's!
Courtesy of SEO vBulletin Services tags: seo, vbulletin, vbulletin seo, link canonical, canonical Google, MSN, and Yahoo have just relased a new tag for stopping duplicate content even further. Combining a good and valid vBulletin Robots.txt file along with the new canonical tag can destroy any duplicate content penalty your vBulletin powered forums may have had going on. Quote:
Is rel="canonical" a hint or a directive? It's a hint that we honor strongly. We'll take your preference into account, in conjunction with other signals, when calculating the most relevant page to display in search results. Can I use a relative path to specify the canonical, such as <link rel="canonical" href="product.php?item=swedish-fish" />? Yes, relative paths are recognized as expected with the <link> tag. Also, if you include a <base> link in your document, relative paths will resolve according to the base URL. Is it okay if the canonical is not an exact duplicate of the content? We allow slight differences, e.g., in the sort order of a table of products. We also recognize that we may crawl the canonical and the duplicate pages at different points in time, so we may occasionally see different versions of your content. All of that is okay with us. What if the rel="canonical" returns a 404? We'll continue to index your content and use a heuristic to find a canonical, but we recommend that you specify existent URLs as canonicals. What if the rel="canonical" hasn't yet been indexed? Like all public content on the web, we strive to discover and crawl a designated canonical URL quickly. As soon as we index it, we'll immediately reconsider the rel="canonical" hint. Can rel="canonical" be a redirect? Yes, you can specify a URL that redirects as a canonical URL. Google will then process the redirect as usual and try to index it. What if I have contradictory rel="canonical" designations? Our algorithm is lenient: We can follow canonical chains, but we strongly recommend that you update links to point to a single canonical page to ensure optimal canonicalization results. Can this link tag be used to suggest a canonical URL on a completely different domain? No. To migrate to a completely different domain, permanent (301) redirects are more appropriate. Google currently will take canonicalization suggestions into account across subdomains (or within a domain), but not across domains. So site owners can suggest www.example.com vs. example.com vs. help.example.com, but not example.com vs. example-widgets.com. Sounds great can I see an example in action Sure, here is a wordpress blog that has implemented canonical URL's already: http://obamanewssource.com Our vBulletin powered site that has made this implementation is only a test site. How can I check if its working Go to your showthread page, and hit view source, and search for "canonical" and you should see it automatically added. If its not automatically added for whatever reason, remove the product file thats attached and make this simple template edit to the end of your vBulletin headinclude template (it's a good idea to do this on all headinclude templates) Code:
<if condition="(THIS_SCRIPT == showthread) OR (THIS_SCRIPT == showpost) OR (THIS_SCRIPT == printthread)"> <link rel="canonical" href="$vboptions[bburl]/showthread.php?t=$threadinfo[threadid]<if condition="$pagenumber>1">&page=$pagenumber</if>" /> </if> <if condition="THIS_SCRIPT == index"> <link rel="canonical" href="$vboptions[bburl]" /> </if> Install Instructions Upload attached product.xml file to your vBulletin forums using the built in product manager Uninstall Instructions Sorry to hear the modification isn't working, to uninstall it, simply use the uninstall function of the product manager Download Now

showthread.php?t=26237&page=9 What is displaying as the cannonical URL for showthread.php?p=179223#post179223 (This one should show, showthread.php?=179223, search engines don't bother with the relative anchor #post179223) |

Even changing it to Code:
<link rel="canonical" href="$vboptions[bburl]/forum.php" /> Yes it should add the &page to it. I thought I had multipage support enabled on it, but apparently not. I apologize for that as I only have a test forum that doesn't have any multi page threads but I guess i'll have to create one now. Edit: I just downloaded the version attached and installed it on a test site and its adding the page numbers okay. |

Install Instructions Upload attached product.xml file to your vBulletin forums using the built in product manager Thats all there is to the install. If it doesn't work, the first post also contains information on a manual template edit to fix that. |
