The purpose was to catch more traffic for product related keywords via content blog and I succeeded in that. I am getting traffic for such keywords via content blog that my ecom site could not get. Now I want to redirect my content blog visitors to ecom site. Can anyone comment who has done this?
Personally I add links into my content. Or at the end pointing out they can find said product on this ecom site. I don't say its my ecom site. I also don't do this for every article a banner sits on the side if they wont to go there and visit. To me I don't want to get redirected automagicaly if I am looking for a specific topic one not related to purchasing.
I run an off-site blog for product releases, I always offer links back to the main ecommerce site as well as other sites, Amazon, iTunes etc.
A lot of our customers prefer to buy from Amazon. You shouldnt be worrying too much about SEO but more "what would the reader want" I think if you start redirecting visitors to your main site you'll just end upsetting people and loosing traffic. You may end up loosing all your potential customers.
