Handles a few basic SEO related improvements such as:
- "hreflang"
- "canonical"
- "noindex"
Being reported to work on PS >= 1.6.0.9 .. but it should work on PS 1.6.x.x too
For production use the latest stable release
For developing or Pull Request please use only the dev branch
Insert the <meta rel="canonical"> html tag to avoid content duplication
Query string is removed only when needed, pagination is retained and handled (an existing "prev/next" mechanism is needed, newer PS already does it)
Handle multilingual sites.
Insert the <meta rel="hreflang"> html tag, a default lang is handled too.
hreflang meta is only added on canonical pages, as explained in the following image and explained by Eoghan Henn
Automatically assure a <meta robots="noindex"> tag is added to every PS controller that should not been indexed by search engines.
This allows for big "robots.txt" cleanup .. and a better SEO
The phylosophy is "Don't use robots.txt to tell robots to do not index a page, it should be used to block them .. it's different"
