It is my understanding the pretty URLs don’t add anything in terms of duplicating content. However, recently I am seeing duplicate pages on a number of sites i.e.
my website.com/index.php
These are definitely being seen as duplicate pages because the title tags and meta descriptions are all coming up as duplicates. Plus, type the two URLs in and they come up the same under the two URLs.
Is it best to use a 301 redirect to resolve this? Will be a pain doing this over 100’s of pages.
This is what the canonical URL meta tag is for. I am pretty sure you are an SEO Helper user. It supports this tag for you. It makes it easy to automate in a partial as well
There are videos on the product page. But it’s easy. Either use the SEO Basics stack or the canonical url meta stack. And you are done. Just having that in the page should cover 99.9% of the use cases.
