What is the best and safest way to direct traffic from unused domains (about a dozen) that have traffic to a primary ecommerce website? The domains are indeed keyword rich and highly related to the product being sold on the ecommerce website. The thing is I do not want to do a straight 301 redirect because any negative seo clown could blast those with links, and I don't want to monitor inbound links for dozens of domains. I'm thinking just a short blurb of text and a couple related pics for each domain with a nofollow "example.com" non-keyword rich link pointed to the ecommerce website's homepage for each site along with a noindex tag for each domain being pointed. All the domains will be on the same IP as the main ecommerce website I want to point them to.
I don't want to hide what I am doing from Google, but want to forward the type-in traffic to the main ecommerce website so that we get the added sales. Is this risky for the main ecommerce website or should I use some different method (302 redirect, Javascript, etc.)?
