At the moment as part of my link building strategy for my main website I have about external 20 blogs (on two different hosting sites)and each blog provides content for a specific product and provide links to the main site.
My plan is to now move all the content from those external blogs into the main sites blog (to increase traffic and authority?).
Originally I was going to export content and put 301 redirects from the blogs to the main site.
Now I am thinking to set a canonical version on the main site and leave the blogs running (so I don't lose links - as they rank in SERPs for some of my keywords)..
What do you guys think would be the best strategy?
