I mean the same, although i think it is not all about user metric but site structure ( siloing ), unique content. Apparently all this reduces in some way back to user metrics.

Last week I reported that I observed about 6 sites rotating upwards through the SERPs for a certain query, to page 4, then dropping. This week, I've watched those same sites go full circle again. Yesterday, two of them dropped to page 16; today one of those two is back up to page 4 and the other is on page 9. Tomorrow, the one on page 9 will be up to page 4, and the one on page 4 will drop to page 15 or so. The other sites will rotate up in the same manner. These are all "similar" sites according to G, so I assume they are testing user metrics for those sites.
