Secondary listings dropped rankings

[Noise-Barrier]

I have been noticing a lot of rankings are dropping. I am particularly seeing the secondary listings dropping. For example I may have had a listing at both 2 & 3 for the same keyword search. Now the second listing (#3) is dropping to the second or third page while the first remains steady.

Is anyone else seeing this recently? Could there be an algo change in how these secondary listing are treated, perhaps allowing more diverse SERPs listings?

Could be. I can see Google seeing this as not the ideal search experience.

We have not seen this happen yet in google.es, but could be something that is spreading now.

My own sites and of all my clients did not experience any drops at least the last 18 months.
