First of all happy new year to all bhw members and a big thanx as I am newbie and all these posts really help me to understand SEO. I'm thinking purchasing some domain which I found that have some decent search traffic related to my keywords(I used google keyword tool)and redirect to my main site (301). I'm wondering if this will help my main domain as it is only 7 months old and I need traffic and sales ! Do I need to build backlinks for these domain? If you have for example 10 domains which redirect to main site helps?
