I was trying to understand why Googlemaps tells me that I have so much pages without canonical URL and tried to find the reason why.
I found that the searching scheme doesn't put a canonical URL in the header. This could amount for a fair number of such pages pointed to by Google.
More, on my board, I use a tagging scheme which also displays its results using the search_results template.
This could explain several hundred of such pages without canonical URL on my board.
Was this done by purpose?
Can somebody shed some light?
Thanks in advance.
