for a long time whenever you did a search for "Best X" Google always sent you to a short list of spammy review sites. Google kicked most of them to the curb but for some reason left the Wirecutter.
Before Google decided to hand the keys to Forbes though there was a vibrant market in competitive spammy sites for topics like that but at one point Google decided that Forbes and The Wirecutter should win all the time so since then we've had uncompetitive spammy sites and no way you can make a better spammy site and win market share.
