This question already has an answer here:
For legal reasons I had to change my business name, and get a new site name and address (very long story).
I had to forward my old domain to this new one, but the old domain has like 200+ back-links, and the new site has zero. How does this impact SEO and what do I do in a situation like this? Do I start from scratch, or is there a way to capitalize on those back-links on the old domain name?
