Mobile SERP Changes in Google 2017 – More Tests?

[mykoolfriend]

it looks as though Google is hot on finding the perfect SERP layout. So here’s what mobile SERP changes I’m seeing on the Galaxy S8 right now:
Key changes:

Rounded edges for each search result
URL moved to top of result and now black font
Lighter shade of blue font in title tag
Less harsh grey font in ad copy

Whats everyone else finding?

Hi mykoolfriend and welcome to WebmasterWorld [webmasterworld.com]

Don't see "Rounded edges for each search result " In fact, I'm currently not seeing any changes at all.

However, this is not out of the ordinary. Google often experiments.

This appears to be just a test. Most of the time I am seeing the standard unchanged look.

It does seem like this is a wider test than normal. I've encountered it two different times so far. I would speculate that this test style might be closer to becoming one of the 1,653 annual approved launches (aka changes) by Google's that successfully survived from their 9,800 yearly live traffic tests [google.com...] . On average Google is testing about 27 different serps every single day so I usually don't spend too much time documenting or worrying about these tests.
