Is it really necessary to constantly upload at Shutterstock to maintain sales?

Can a folio sustain sales with irregular uploading?
What are your views/personal experience on this?

There are those that say yes, they have pretty consistand downloads without uploading constantly. I would guess that they have exceptional portfolios.

I myself have not found this to be the case though.
For me it is upload or die on SS.

I didn't upload any files for a couple of months at shutterstock, and sales plummeted, last month I started uploading again, and found that my sales in March were almost 3 times what they were in February, even though I only added an extra 20 files, which equated to 10% of my existing portfolio.

What is your regularity?

I found that it is necessary to upload around 5 new photos every weekend. That seems to carry you through the week.

I stopped for a about 6 months after my surgery last spring and sales went totally down the toilet.

Im not sure if you upload new images, old ones  go on with its sales

Yes, they get mixed in with the new ones.

I didn't upload for 2 months last summer and my SS income went down roughly 15% (a lot more than the other agencies). The moment I restarted submitting, things went back up.

You really don,t need to upload that much to keep you portfolio "alive". I do believe constant uploads are the keep for maximum portfolio exposure at SS.
