I have been no.1 for a while for a competitive search term in yahoo but I receive little traffic from it (5-10 hits per day). Yesterday however, this keyword produced 200 hits! Today, it is back to normal and has produced only 5 hits today!
I have asked friends on different IPs and PCs to run the search and I am still position 1 for everyone who has tried!
Does anyone have any idea why there should have been a boost in traffic yesterday! If I didn't know better I would assume google had gone down!
