One of my clients go approached by a SEO firm to purchase redirected from a website. The website curerently ranks number one in Yahoo for an expensive terms that relates to their business. The title and snippet Yahoo shows are not up-to-date and are off-topic as is the domain.
Looking at the backlinks, it appears that this SEO firm got control of a well-ranked domain in another topic area and then linked some sites they control with themes and anchor text on the expensive term.
I'm trying to figure out all of the implications if my client were to purchase this redirected traffic.
1) obviously they do not want a longtemr contract since this is dodgy at best and the seo firm could easily stop supporting the site with the expensive term
2) it seems that if they do a 301, a 302, or a client side redirect there are different implications for whether Yahoo (and other search engines) will pick-up the right titles and snippets. I do not know enough in this area though to tell what all the fine points are.
3) There might also be some concern if they really have authorized control to the domain that was once a legitimate site in another topic area
I am probably missing out on a bunch of other issues - this goes fairly far afield of my normal search marketing activities.
