The problem is that right on your front page I see that the estimated annual comp for a G6 engineer at Google is expected to be $226,673 salary/$212,061 stock/$50,939 bonus. The stock portion, however, includes both brand new offers and those which have benefited from many years of appreciation, making the number effectively meaningless.
Even after digging in, there is no way on the site to restrict it to only new offers.
I personally have not reported my salary on levels.fyi or any similar website because my shares were granted pre-IPO and I don't want to further distort expectations for what an average software engineer is expected to make.
