I'm still seeing what I reported last - a traffic boost that's holding, but all based on such long tail phrases that I rarely see the same ones twice.
However, I've noticed a pattern: exact keyphrases may not be repeating, but the concepts are. I'm getting repeat visitors for keyphrases that are differently worded, but mean the same thing. And I don't just mean rearranging the words, but synonyms and... well, just VERY different phrases to express the same query.
It's almost like they're using my site as a test to see if their machine learning understands the concepts behind words - and it does. I'm getting very few non-targeted searches where it's obvious to me that the visitor won't be satisfied with the page Google sent them to, and I used to get a lot of those.
I'm not sure what this means, or maybe it's just some odd fluke on my end, but it strikes me as very interesting.
