Bing: 90% Or More Of Their Core Ranking Algorithm Uses Machine Learning

Bing Machine Learning

Yesterday at SMX West, I did a panel named Man vs Machine covering algorithms versus guidelines and during the Q&A portion, I asked the Bing reps Frédéric Dubut and Nagu Rangan what percentage of the core ranking algorithm is AI or machine learning based. To my surprise, they guessed over 90%.

I know Bing is proud of AI for rankings but I didn't expect it to be 90%+. I would have thought closer to 20% or so.

Here are some tweets from the conference about it:

The second one is from the speaker.

So Bing is not shy about this figure. I've asked Google this question numerous times, and they always shy away from the answer. The closest thing I got was that we don't need to worry, the algorithm won't run away by itself, Google still needs to be able to debug ranking issues and if it is all ML/AI based, it is too hard to do that.

So I then used that tweet to get Google to answer the question - fast forward, it didn't work - yet. But we did get some responses:

Will Google ever share that number? If they do, how high do you think it would be? I still would guess when it comes to core ranking of the "ten blue links" we would be at about 20% or so. But I was totally off when it came to Bing.

Why does it matter as Gary from Google said above? I guess it doesn't but it is interesting to see how much each search engine trusts AI.
