I recently (a month ago) started optimising my pages with keywords that are more unique to each page. MSN has picked up on the changes immediately and has been visiting 3-4 times a week. My search results are mostly 1-5 and not over 12 on the lists for 10 product lines I have worked on. The results from Yahoo and Google searches are much less exciting, but are improving somewhat but are only visiting once or twice a week, if that and are slow to scan a number of the total pages.
Has anyone else noticed an engine being particularly hot about a site while being snubbed by others? Does it have to do with MSN being a newer kid on the block?
