劈材解释了,
Any time you type in a keyword, as Google we have gone out and crawled and stored copies of billions of [websites’] pages in our index. And we take the keyword and match it against their pages and rank them based on over 200 signals — things like relevance, freshness, popularity, how other people are using it. And based on that, at any given time, we try to rank and find the best search results for that query. And then we evaluate them with external raters, and they evaluate it to objective guidelines. And that’s how we make sure the process is working.
我猜下边这个解释更着边,
News outlets reported on the Trump “idiot” results
earlier this year. If you search the term now, in fact, you’ll mostly get pictures from stories explaining why it happened. It appeared to be the result of
outside parties gaming Google’s search results, a
well-known tactic known as “Google bombing.”
