A few months back a couple of people put up some stats of their serials. I thought I'd do the same from the perspective of someone who has a smaller readership, as well as tying that into the visibility provided by this site.
I started my site, Tales from a Thousand Worlds, at the end of April 2015 as a place to share my short fiction in a serialised form. Given most of my short fiction is in the 8-10K range, it could be broken up into smaller parts which I felt would work well. Getting readership was hard, even with trying to advertise it in various places and readership stayed small.
Eventually with no traction being gained, I tried something new. Firstly I started a proper serial (Echo of the Ages) which, while hosted on the same site, is kept separate. Secondly I listed on here. Tales from a Thousand Worlds was listed at the end of May and Echo of the Ages was mid July.
The results were fairly instant.

The biggest spike came right after the two reviews I got, with 150 views in a single day, followed by 100 a few days later. The view rate kept up averaging 10 readers and 20-40 views a day while the reviews remained visible on the front page of TWG. However since they have been pushed off by newer ones, readership has slipped. It is still averaging more than it was pre-TWG, but no longer at the heights it was. If I was to guess, those hits are from readers I picked up during the high visibility stage and have stuck with the stories.
So it would seem that this site is effective at gaining readership and that visibility is very important, especially reviews. Getting new ones on a fairly regular basis to keep you visible is very much a key to success to those starting out, at least until such time as word of mouth begins to kick in.
