I have a domain ranking #3 for my main keyword, I also have 3 other domains in that niche but none of them are ranking in the top 10 the next closest is ranking on page 20 but I never do any SEO for it but it has a page rank of 1 and is about 2 years old now. I am wondering if I place a backlink for my #3 site to one of my other domains will that other domain shoot up to #1 since there both in the same niche? I have read that a niche related backlink is more powerful then non niche related links and I am looking for a way to secure #1 ranking. Any help would be appreciated. Basically I want to know if I use that #3 ranking as a push to secure #1 ranking for another site will that work?
