I had an interesting conversation with a programmer whom I respect this morning who was looking at Yahoo Local and Google Maps business listings (in an industry that presumably has nearly 100% website penetration). He pointed out the following:
â€¢ Google and Yahoo seem to have almost the same name/address/phone info
â€¢ But Google has much better abstracts and web pages (i.e. web site url).
â€¢ Google has about 80-90% of its business listings associated with web pages,
â€¢ Whereas Yahoo has 52% of its business listings associated with web pages
I have found Yahoo Local’s ranking algo to be simpler than Google’s but it appears that there is more difference in the backend than just that.
