I'm gonna drop some stats here - across the board on series between a new series (launched on the new UI) to Premium to an un-updated F2R series. I haven't got data on a recently updated series on my platform yet but just to give you an idea:
To give you an idea, I took stats from 1st March, 3rd March and 5th March and it will look like [1 Mar Stat] | [2 Mar Stat] | [3 Mar Stat]. To give a matter of perspective, I have over 14k subscribers total so it's more about stats increases and decreases than concrete numbers here.
F2R - Vee - not updated since Sunday
Views: [213] | [50] | [57]
Likes: [38] | [5] | [2]
Subs: [12] | [2] | [4]
Overall, on the free-to-reads, I've noticed that there's a trend upwards on subscribers again after the initial panic over the site change. I think the initial dip is due to readers not necessarily reading over the last few days, but instead clicking about and just getting used to things/exploring and the usual mid-week dip in reading figures. I'll try updating Vee soon and see what happens on an update day for an established series. But in general, while a little worrying, I'll worry more if I don't get back to those bolded stats after a few weeks.
F2R - Dreamers of Draiocht - New under new UI
Views: [N/A] | [N/A] | [92]
Likes: [N/A] | [N/A] | [11]
Subs: [N/A] | [N/A] | [72]
If I add in today's subs as well, I think I'm almost at 90 subs in 24 hours. My last series exploded faster, but it had a much more BL heavy cover and was isekai so... All in all, new works don't seem to be affected and appear to be growing at the same rate as before with little change under the new system.
I'm not going to do a full release on my Premium series stats as I'm not sure what's considered 'business information' for Tapas, but I'll say that views are down but subscribers are up on the Premium series I checked on my account - mirroring what I found on F2R series.
It'll take a good few weeks though, to see what this data means. Right now, I just think it's evidence of people being spooked.
