Here's what I've noticed lately with my sites:
I have noticed two sets of SERPs for me in the past 2 weeks. 1 set shows up about 80% of the time (and has been up all the time for the last week) and then 2nd set that shows up maybe for 1 day or so every like 5-7 days.
What I have noticed is that when the 2nd set SERP shows up several of my sites disappear from the page 1 for their main keyword(can't be found past the first 10 pages) while the sites that are on page 2 on the 1st SERP set show up in the top 3 of the on the first page. This is for like 5-6 sites. Then for the few sites that have been around for like 2 years or so they remain stable and are at the same position whether SERP 1 or SERP2. This movement back and forth are to sites that are about 1 or less years up.
It's funny though that when I see a group of sites reappear on the first page for their main keyword I know that the other set of sites are gone from the front page (and when I do a query for their main keyword of course that is the case).
But over the past 2 weeks the 1st SERP is there most of the time. Just today I'm getting the SERP 2 set. The problem is my traffic evens out since I lose the ones from SERP1, but gain those from SERP2. I wish the 2 sets of SERPs can be one so I can see my whole traffic.
