I feel like Google would do better by letting users register filters. For example I'd filter out ranker, vulture, and similar sites. That would seem like more signal for Google than not having that user preference. More signal = better searches = more searches = more money.

You can easily add that filters by yourself: just append "-site:ranker.com -site:vulture.com" to your search query, e.g. by setting the search URL to: "https://www.google.com/search?q=%s+-site%3Aranker.com+-site%..."
