This is apropos...<p>Google's old link-based authority algorithm, pagerank, isn't alaysing the same web anymore. I think there's barely any signal in links these days.<p>The first major event was Google itself. Once you use something as a metric, it becomes currency. SEO vs anti-spam became a defining cat and mouse game. This kind of stuff was born then, and antispam was meant to curb it.<p>The second major event was user generated content. The old link pages and blogrolls die slowly. Comments, twitter, and such become the way links are shared. High signal, but extremely spam prone. Google tapped out of this early, and mostly ignore user generated content.<p>The third major event is facebook, and facebook like ways of doing things. This made most regular people's content unindexable. Search for esoteric keywords used to return a lot of forum results. Still does, to an extent. The thread is usually years, or decades old. What's left on the open web is a subset, a non random subset.<p>Wikipedia is one of the last sites that does "hypertext" the way pagerank assumes the web works.<p>In any case, I feel like search (or what search used to be) is in decline. There isn't as much web to search anymore, in a sense. The broad brush way of doing antispam (eg user generated content is just ignored) makes more sense. Why deal with all that noise/spam, just to search what's left of the old web.<p>What's left? User behaviour, a la analytics. That's makes for more feedback loops and winner takes most dynamics. Localisation became localisation to your bubble. Meanwhile "officialness" measures aren't against google's ethic/aesthetic anymore. They got burned by the "fake news^" crisis, and the quick fix was officialness. In for a penny. In for a pound.<p>Meanwhile, web search is increasingly just another thing that google search does. It searches "your" data, content of your devices, search history and NN generated whatnot. It searches news, ads, returns answers to questions, does math... There's nothing new about seo scams, antispam just isn't Google's primary solution anymore. Just default to other ways of returning results.<p>I'm calling it. Web search is dead. Long live the new websearch.<p>^Circa 2015 usage, not the current
