A client of mine has four separate domains (very good ones, I might add) that are all almost exact copies of each other, with only "SEO keywords" being different. While making a new site for them that's modern and responsive, I'm also consolidating to a single site to avoid duplicate content.
Should I do a bunch of individual redirects from particular urls to new, relevant ones, or should I just do a blanket redirect to the home page of the new site? For example, should I redirect
newdomain.com/contact-us, or just
newdomain.com? Does it make an SEO difference?
Secondary question: I also have an idea to have multiple landing pages. The landing pages would have localized keywords aimed at bringing in search results. For instance, I may have a landing page called
domain.com/new-york and another one called
domain.com/miami. Is this a good design decision for SEO?
