Photopost Pro Canonical Links Tag for SEO
Mod Version: 1.00, by cellarius (Coder) cellarius is offline
Developer Last Online: Oct 2017 I like it Show Printable Version Email this Page

vB Version: 3.8.2 Rating: (4 votes - 4.75 average) Installs: 31
Released: 30 Apr 2009 Last Update: 30 Apr 2009 Downloads: 89
Not Supported Uses Plugins Template Edits Auto-Template  

Note on versions:
This should work with every vB-version that uses the plugin system (3.5 and above). If not, please let me know. It also should work with older versions of Photopost. I tetsted on vB 3.8.2 and Photopost 6.22.


The problem: Duplicate content


One of the biggest problems of Photopost Pro when aiming at SEO-optimization is duplicate content - myriads of possible urls point to the same page. This leads to heavy penalization by search engines like Google. Although this has been critizised for years by Photopost customers, the developers were less than helpful, stating this was not "an issue with our program at all"; there are no indications whatsoever that this will ever be addressed.

A solution: canonical links

Not long ago, the major search engines (including Google, Microsoft and Yahoo) introduced a new tag, designed to deal with just that problem. It allows you to define a canonical url for pages that can be accessed via various urls. This is just what Photopost needs and should really help SEO-wise (see Googles explanation):
<link rel="canonical" href="URL" />

What this product does

I wrote a small plugin that is only active on Photopost's showphoto.php, this being the most important and most duplicated page. It extracts the photonumber from the URL and constructs a canonical url that is made up only from the URL to the script and one parameter (the photo number). It works with both Photopost's URL versions (standard and spider-friendly). Additionally, if the URL that was used to call the page is not identical to the canonical URL, a "noindex"-Tag will be added.

Example:
URL to call the page:

Block Disabled:      (Update License Status)  
Suspended or Unlicensed Members Cannot View Code.

will insert:

Block Disabled:      (Update License Status)  
Suspended or Unlicensed Members Cannot View Code.

while

URL to call the page:

Block Disabled:      (Update License Status)  
Suspended or Unlicensed Members Cannot View Code.

will insert

Block Disabled:      (Update License Status)  
Suspended or Unlicensed Members Cannot View Code.


Installation
  • import the product
  • if you're using Template Management System, you're done. Otherwise, add $cel_photopost_canonical at the top of your headinclude template.

Hi, sounds great, so the plug-in is only active for the photopost urls within my forums. I have links from all members profiles as well as their posts to their photopost pictures..??

** installed as of now **

No, this plugin is not active in the forums at all. It is only active on showphoto.php in your Photopost gallery. There it inserts the tags inside the page header. You won't see any difference at all when looking at the page in your browser, it's only in the page source. It's for the search engine spiders.

That's of no interest for this mod, and this mod will not affect them. It only tells the search engines that there is one page [the canonical one], that can be addressed via different URLS. So the search engine knows that it is not duplicate content and won't penalize you.

You may want to read the explanation on Google Blog I linked to in the first post.

Same here. I wonder how long it will take them to adapt their product to vB4. Scott Molinari hinted on vB-germany that there might be a full-blown gallery coming from Jelsoft somewhere in the future - if that's to happen, I'm a sure buyer. Hell, if that new taxonomy system coming with vB4 is any good, perhaps the albums can be modded into some kind of gallery. I'm actually looking forward to try that

Quick question, but does vbgallery work in the same way and does it require a similar solution to PhotoPost Pro? If so, will you be making a mod for vbgallery as well?

Probably - I'm not that familiar with vBG. Though I doubt that the problem can be as bad as with Photopost. I have vbseo installed and the SEO-gurus there have up to now not been able to handle Photopost - that's how bad it is . There is a plugin for vBG, tho. And no, I won't do something for vBG. As I said, I don't use it myself, and with vbseo there is a excellent product available for SEOing.

At least the current db schema and code seems to make it pretty easy to build a gallery type addon based on (album) pictures - if I only had enough time ...
