The other day I reported how Google said there is no such thing as the top three ranking signals despite what may have been said before. I said it is likely because some queries weigh some signals more important than others, such as QDF (query deserves freshness – Google it) and other things.
But what about having different signals with more weigh based on the industry or topic of the query? John Mueller of Google said “I think it makes total sense” to have algorithms that weigh different signals dynamically based on various of factors. He said there is no one-size fits all approach to ranking signals. He said Google “probably” does value links less in some industries that are more susceptible to link spam but he qualified that saying that was from his “limited point of view.”
