I am combining the two sites into one awesome amazing job dropping e-commerce, blog and resource. I will be using the domain for Site A.
Site B, the soon to close crappy e-commerce site, does get some traffic, a bit of business and has a variety of both good and bad back links. Not all that many and the domain authority is next to nothing. My question is...
Should I bother doing a page by page redirect strategy from the old crappy Site B to the new awesome Site A?
Should I do a blanket redirect for the whole domain?
Should I just kill this domain and put all my eggs into Site A?
Site A gets a bit of traffic too but has a low DA like Site B. Mainly because I have not put any effort into this site. But we do very well in local search and I have no doubt we will rise once the new site is launched.
Also... How would I best achieve whatever your recommended advice is? The new site A is on wordpress. The old crappy site is on 3dcart.
Hopefully that wasn't too many questions and I didn't leave any important info out. I know it's a big question to ask as a newbie but I plan to participate in these forms quite a bit now.
