dear seo experts, currently i have created video niche site which earned page rank 3 6/7 months ago. i have optimized the site by using google webmasters guidelines, however still my site is not in among top 50 result . however i have two other domains, which is 9 years old those domain has page rank 4 . one of my friend who does SEO job he advised me to redirect both domain to my video site and he think that will improve my rank and indexing . my question is which method would be better ? 1. create a backlink in those domains ? 2. use 301 redirection method to redirect both domain into video site ? please suggest what option would be better. thanks
