How was your month? Mine was lousy as both iS and SS were heavily down year-on-year. iStock, of course, because of massive pay cut they awarded me last summer, but SS was badly down too, partly due to bad luck with lack of ELs and few SoDs and partly, I suspect, because I've lost out in the latest best match lottery. With the two main agencies down, there's not much the others could do to repair matters.
DT was interesing though, it pulled in almost exactly the same as in 2013 -  less than 50c difference! - but the sales volume was 2.4 times greater (there were probably some ELs last year to help boost the RPD).  My chart shows that sales volume has been rising for all but two of the last 10 months, despite my scarcely uploading for a large part of that time, but the earnings have not followed suit, as RPD has dropped from around $1.20 to about 73c. So Jan was the fourth best month of the last year, even though DLs were 75% higher than the average for the year.
Alamy was average, which was a bit better than the previous year. DP is increasing, CanStockPhoto was normal, 123 up a little, BS was actually up a little bit on Jan 13 but still 60% below the BME. Veer made enough for a pint of beer, which is pretty good by its standards. 
So the little sites did slightly better for me, but nowhere near enough to make up for either iS or SS, DT was flat but is increasing sales as RPD falls.

I had an absolutely best month ever (like 3 to 4 times what I normally would make).

The reason for this is easily explained: I have a set of approx. 250 editorial winter sport photos in my portfolio and with the Olympics in Sochi just around the corner these photos have been selling like crazy. The funny thing is, that although the photos are on five different sites, sales skyrocketed only on SS, BS, and, to some degree, on 123RF, but were dead in the water on DP and DT.

tickstock! did I miss something? you're back?

Gillian, Ploink, Melimage!  just out of curiosity. Do you have large, medium or small portfolios at SS? with large I mean over 2000 files.

BME
Very good Alamy
Good Shutterstock
Average iStuck and Fotoliar
Dreamstime absolutely inexistant��� (they still exist??)
My first 3 sales in one year on GL

And if I compare to January 2013, the month I begun to upload on microstocks, my growth is 2261.34% !!! (But okay one year ago I had very few images uploaded)

I have around 3.300 photos there (2.200 of them editorial sports), I'm with them since 2006.

SS up to normal from the December drop and growing.
FOT also up and growing.
DT frozen in one of the low cycles since last summer.

January a bme by far for me on ss
dt pretty average

its made up for the December slump anyway 

IS dollars for January were the worst since December 2012. With correction of the payout percentage the results should look much better. I suspect I'm getting paid at 20% instead of the expected 30%. Adding half-again more income would put me in back into the "normal" income band for last year. I'm anxious for the corrections to be applied. I am highly concerned with the continuation of decreasing downloads. Percentages won't matter when downloads hit zero.

The longer view good news is that my very old portfolio did better income in 2013 than I saw in the last half of 2011 through 2012.

Alamy was an average month though my income trendline is slightly falling even as I add more images. A moving average Per Image Per Year of $0.77 from 1.5 years ago has now fallen to $0.37. I'm sure much of this is due to uploading a lot of speculative low interest RM Editorial shots just looking to see if I can discover a niche somewhere or find a lucky payday. However, falling sales prices at Alamy certainly is a factor.

Better than December, but a big drop from Jan 2013 (my BMY). Alamy, Veer, and Pond 5 were the ones who dropped the most. Veer dropped a full order of magnitude with almost just a few sub sales this month compared to plenty of regular sales and a few juicy ELs Jan 2013.

DT was pretty good after an absolutely dire December. SS ok. Nothing to get excited about, but not worth slitting my wrists either. My best Seller at SS has been pretty much removed from the search. This month sales of cold and freezing themed images made up the difference, but that won't help for the summer. Not that the image wasn't a good one, but it got to the top of the search through a glitch (and good sales) and was on the first page for a number of years 'til they changed something and bumped it to the second page overnight. It has been slowly falling since then. Search placement is king, and image quality is only part of the equation.

mine definitely qualifies as small... .

IS Exclusive; total income +22.6% compared to January 2013.

Includes PP and GI from December, and RM/Video from other outlets.  Doesn't allow for incorrect royalty rate being used for most of January, so will actually be a little more when that is corrected.

As KB says, sales numbers are somewhat down, but as long as the $$s are up, I'm rather more sanguine about that.  I'll not worry about it until it affects the income!
