I have a client who is very focused on getting ranks in Yahoo! Convincing him that focusing on Google is much more important isn't going to happen. He uses Yahoo! He ranks very well in Google, and his site is relatively well-made with no glaring on-page issues. His backlink profile is also not an issue.
I'm trying to find ways to rank specifically for Yahoo! since we're ranking well in Google and the client cares a ton about Yahoo! I know Yahoo! uses Bing's algorithm, but results aren't identical in the two engines.
Does anyone know of big, glaring difference in the two algorithms that would result in great Google ranks, but almost non-existent Yahoo! ranks?
I have him in Bing webmasters, his local SEO and citations are good, his backlink profile is good, and his on-page is decent.
