Take the 2-minute tour ×  I want to ask about canonical URL.
Lets assume this URL structure:   Simply put, there are multiple
URLs that display the same content. But only /category_A/page1
is original(canonical) page. My question is if it have any
impact(bad/good/neutral) considering SEO if I will have
canonical URL pointing to /category_A/page1 placed in this same
page /category_A/page1 ?  The reason for this is, that its much
easier to just put canonical URL into head of every page than to
trying find out in which page it is not needed (its the same
page as canonical one)  share|improve this question  1 Answer 1
up vote 3 down vote accepted  just do it  you described the
perfect use case for the canonical tag. the canonical tag is a
kind of failsafe against wrong URLs (or URLs with unnecessary
parameters). so it's good to have it even on the page with the
URL the canonical points to.  share|improve this answer thanks,
just wanted to make sure I am thinking the right way... –
