Search Engine Optimization


1. Content

2. Meta Headers

3. Duplicate Content


<link rel="canonical" href="https://wackowiki.org/doc/Doc/Français">


should be useful for pages


https://wackowiki.org/doc/Doc/Français?show_comments=1
https://wackowiki.org/doc/Doc/Français?show_files=1

to avoid duplicate content penalty from Google.


Can the link be relative or absolute?
rel="canonical" can be used with relative or absolute links, but we recommend using absolute links to minimize potential confusion or difficulties. If your document specifies a base link, any relative links will be relative to that base link.
