I have bought two domains with different gTLDs. I have .net, .org and .ca TLDs. I have some SEO to get the top rank for the keyword of the domain. My .ca domain is already ranked as #2 for the keyword. However, it is still not at #1. My question is: should I redirect .net and .org to .ca or make 2 pages website and do SEO to rank them as well? What is the best way to get #1 for that keyword? Any thoughts?
