Pudders looking today we dominate several keywords. The other 3 listings have nothing to do with the first. It's about as close as saying searcher A once bought a kiwi fruit and a car, so he must want a kiwi fruit mention and car from us and they dig deep to find it. In a bundle of kws it's that far off. Think searching for a particular sensor for a production line, getting that as first and then an airplane wing load tester as #2 and a blog post about the damaged a380 as #3 all from our site.
They are trying to do their own "you may also like" which IMO they are years away from having enough data. It's really unfair to our competitors who took a bath Thursday and Friday. Just because someone once bought a black widget that doesn't mean they ever want to buy one again.
This numbers thing can only go so far. We aren't robots, by nature we are erratic. Google seems to think they can break us down to 0 and 1s and will fail in trying to shape our behavior. Although we benefited financially from this change I don't like it.
All of these changes will give rise to twitter facebook, linkedin etc where WE tell the
About our interests through our friends, intersets etc. Where google assumes we have an interest because we searched on something a few times while my long lost aunt Sally was here the others know from deliberate acts.
In the instances I see this happening I can see no meaningful relation between the 3-4 but it will be useful for seo as it tells is what google thinks is relevant.
I like it financially, seems poorly executed or doesn't have enough data yet in our niche. More change for changes sake.
