Welcome to the Q&A Forum

I was wondering if I can use a canonical URL that points to a page residing on external site? So a page like:
www.site1.com/whatever.html will have a canonical link in its header to www.site2.com/whatever.html.

Thanks.

Hello everyone,
I'm wondering what's the best way to prevent/block search result pages from being indexed by Google. The way search works on my site is that search form generates URLs like:
/index.php?blah-blah-search-results-blah

I wanted to block everything of that sort, but how do I do it without blocking /index.php ?

Thanks in advance and have a great day everyone!
