I installed an SEO friendly URL module for tag pages. Now, people can visit any tag page on my site from 2 different URLs:
http://www.princessly.com/tag/product/list/tagId/3/
http://www.princessly.com/tag/royal/
My question is how can I add a canonical tag to /tag/product/list/tagId/3/ so that it's pointed to /tag/royal/ semantically?
A redirection would also do, but that would involve editing one of the core files at /app/code/core/Mage/Tag/controllers/ProductController.php which I don't want to because it's not upgrade-proof. Is there any way to do this without editing any core files?
Probably editing the layout XML to add a canonical tag in the header of /tag/product/list/tagId/3/?
Thanks!
I used a 3rd party extension to achieve this. Just search "Magento seo-friendly tag" in Google.
