Apologies if this is a FAQ, but I get a (depressingly small) number of referrals from search.yahoo.com. However, when I paste the referer string into my browser I can't find the page anywhere in the SERPs, many pages don't seem to be in Yahoo at all.
As I am am accessing Yahoo from Europe, would I be right in concluding Yahoo has different data centers, with the US-based ones being more up to date? Anyone know what the "update lag" might be?
