Have some old exact match domains for popular keywords that are not getting traffic anymore. I've included Canonical links in my primary domain long time ago and now it's time to 301 those useless exact domains to my primary domain.
Just wondering if there is anything else that I need to consider once I implement the 301's? Should I keep the Canonical links on my primary domain for awhile or is it safe to remove them?
Anything else that I may be missing, SEO wise?
Thanks-in-Advance,
John
