Thankfully we already know that Content and Links are the most powerful signals along with RankBrain. However, its always nice to have Google reconfirm their signals whilst they evolve their algorithm.
During a live Q&A from WebPromo with Andrey Lipattsev, the Search Quality Senior Strategist at Google Ireland, SEO expert Ammon Johns suggested to Lipattsev that, knowing what we know about RankBrain, it would surely be beneficial to everyone if we also knew what the other two signals were. And surprisingly, Andrey Lipattsev, obliges… “It’s content and links pointing to your site.” There you go. I think what’s most surprising about this reply is Lipattsev’s candour. It’s a straight answer with little hesitation, that has an air of “look, you know this already” about it. And to be honest, we did. It’s just nice to have the confirmation.
