When I found Altavista it was a game changer. Used correctly, not apt for casual users, you could find everything. And the internet was mostly content. No stores, no astroturfing, no blog pages with random words.
There were many wrong things on the internet at that time. But, SEO-fueled empty-of-content auto-generated pages was not one of them.

I am not an average user. But, the internet is getting also worse for me. And I see similar complaints here in HN.
