The use of rich snippets in numbers
Eric Enge looks at both Google and Bing. And started by looking at auto-suggest:
" This data focuses on queries extracted from Google Autocomplete and Bing Suggest. These queries were mined equally from Bing and Google – we took 250, 000 from each for a total of 500, 000 queries "
" The suggested search queries are a valuable source, but by no means the only source we use, because we felt it was limiting in nature. To that end, we generated over 355, 000 additional queries to test as we detailed above "
Also with regard to lyrics:
" I (Eric Enge) did ask Google about this, and a Google spokesperson said the following: “We only show the lyrics for songs for which we have the appropriate rights”. From this statement, it seems quite likely that Google is licensing the rights to the lyrics that they do show. " ?
