I know its not exactly what you asked for but here are some of my observations over the past 6-8 month using SER and a few other things.
Out of the IMers I have on my Skype, I was the last to use SER on my sites and it was working ok until last year, I don't know anyone sucessfully using SER to rank sites now with most people having moved onto PBNs, Outreach or Paid Traffic. IMO Penguin 4 going real time has added something into the algo that totally turns link juice off from domains that go offline a whole bunch like the majority of the ones SER posts to.
In addition to this, it seems auto generated content has taken a hit too. I'm not sure if this is due to rank brain developing over time, penguin 4, Fred or something else but my money pages using auto generated content in their tiers have either not moved or fallen over time compared to those using 100% human wrote content climbing with a small number having not moved. If you are paying $2.5 for a T1 article then theres no point using SER to post it to a domain you don't have 100% control over as it can get deleted by the web master, the domain can be rolled back to before it was posted, the domain can get deindexed, the domain can go offline totally or it can go offline sparadically due to increased bandwidth requirements from people posting to it using automation.
Although my SER use has been minimal on sites for a few month with a focus more on
the bridge network concept rather than mass automation, I decided
to totally drop the tool early last month having dropped the mass automation side of it a few month before that. I still think building out bridge networks has potential, and y
ou can use SER to post to self hosted domains but Scrapebox has the ability to add media to your posts and host it on your own sites as well as post your content in the correct category making it much easier to make your bridge network/PBN domains look legit.
Although I have been deleting my rank tracker/analytic projects for my SER based stuff over the past few month as I give up on the domain, here are some screenshots of the rank tracker data for the three I still have, the deleted ones looked the same...
SER on Three Tiers, Auto-Generated Content.
Manual Web 2.0, PBN, Bridge Network - 100% unique human wrote content.
Manual Web 2.0, Bridge Network - 100% unique human wrote content.
Some of my PBN, BN, Manual web 2 domains do have SER on the T1 with a select set of engines to try an help with anchor diversification and increasing the referring domains to my pages but most of those links are already dead so I have no current plans to go back to doing that.
