while websites just repeating the search phrase over and over with no answer in sight are at the top

A decade or so ago, this was a really bad problem, especially with sites like Experts Exchange et al. Content farms just grabbing your query and puking back to you. Or, sites that would take a thread on one forum, and then replicate it across 10 other sites as though they're different forums, but it's the exact same posts. But it's gotten so, so, so much worse in the last year or so. Google searches these days are like wading through a septic tank trying to find a microgram of gold.
