Search Engine Optimization

1. Content

2. Meta Headers

3. Duplicate Content

<link rel="canonical" href="çais">

should be useful for pagesçais?show_comments=1çais?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.
