It’s really hard to say. Anyway, I have noticed slight changes in many search results over the past few days but not much new content in those SERPs. That’s usually a sign that someone flipped a switch or tripped over a power cord or something miniscule. So it complicates any analysis of what happened with the two test queries.

Timing is everything, as someone used to tell me quite often.

Aside: what annoys me to no end are people who bury their head in the sand once they decide they believe something and insist something is true even when all the road signs point the other way. A decent SEO’s starting point when looking at any issue is healthy skepticism and the ability to play the odds (or against the odds) instead of seeing in black and white. That’s how sharks play 9-ball. You never know exactly where balls will end up but you play the odds to maximize your chance of running out. Even an open player can’t tell you what happens after a break; but an open player knows how to sink balls off the break, kill the cue ball center table and leave the 1 ball up table. Just doing that consistently will maximize your chances of stringing racks. SEO can be played the same way.
