I often use google to search specific sites, because of this reason.

The simple issue is that people who make money from being first page on Google can afford the money it takes to game the index to their benefit.

This would be true of other search engines too if they were as popular as Google, so I don't blame them for it. Nor do I envy their task. I imagine making SEO gaming harder would be in Google's benefit, so they could sell more advertising.

Commerce has ruined Google's results consistently for years now. It is just what commerce does to everything, when there is money to be made from it. You can't even fly on a plane you paid to be on without being advertised at as thanks for your patronage.
