We are noticing drop of income too. First few months were average, now we are way under last year May.

May was BME for me by a very good margin

Fourth  best month out of the last 12 on SS and within spitting distance of a couple of months that beat it, so not bad. However, a handful of $20+ sales were needed to keep it on track, without those it would have been weak.
Other sites, not so good.

Way down. Most sites slightly down, others average but collapse at SS.

Somehow managed to become my BME on SS (2 years submitting) - I was lucky to get several big sales there (the biggest was 80$) which makes a difference as I have a small port.
FT was good
10$ on BS which was good for BS
DT  - I didn't have a single sale for 2 months, wrote to the support just out of curiosity, they said I should've uploaded more, but then the sales came back
123 was the worst performer of my agencies

I believe I should write an email to DT every day then :-)

For me May was average. Not good and not bad.
I expected more as I uploaded many new images

Hmmm, i also do not understand why my shutterstock portfolio link below does not work... can anyone help?

My May at SS was BME, FT avg, 123rf way down, Alamy 0 sale

How about you guys?
I have 250k images

250k images on SS?  Geez.

Between the worst and the best for May for SS.

Above average overall, but rather poor performance for SS. Very good for FT, IS, P5 and 123, instead.
Maybe customers are churning away from SS, towards its competitors.
If 123 was ~1/10 of SS, about one year ago, now it is ~1/4. Interesting shift!

Overall back to the pretty poor level things have been at for the last year or so minus the last 3 months (mostly due to good or great Alamy sales).

SS continues to be about 50% of where they were. I haven't had a sale over 2.85 in ages (one video last July and some 4.35s last June). It used to be glaringly obvious what days were weekends looking at the monthly earnings report - now not so much and it isn't because the weekend sales are up.

Also a number of the lower sellers were 0 sales last month - FP, SF, GL.

Of course I have no idea about IS, but a few .01 sales won't make much difference.

May started out absolutely fantastic and then declined just as fast.

Sadly, others were even worse.

Good month, 2nd BME
