Google “AI Overviews” Ranking Factor: Evidence of String Match Bias

It’s been a while since I took a stats course so I wanted to confirm these were terrible correlations and happened on an interesting finding that reinforces the idea of trying to win in the long tail maybe. ​

Here AIO says “0.4” is “weak”, and basically string match on the source used (right hand side)…

Meanwhile “0.40” (same number) is considered “moderate”​ and similarly, basically a match on two decimal places on the right for the range of 0.20 to 0.39. And this holds when searching for “is 0.4 spearmans a weak correlation?” vs “is 0.40 spearmans a weak correlation?”
