I am new to adobe stock, I uploaded some photos and didn't get any sales yet.
I was wondering if there is a way to enhance my sales or just wait until someone will purchase any of my photos.
Much like any business you need to promote it. Facebook, Twitter, Instagram, etc ...... also make sure you have lots of good keywords. Make sure your most accurate keywords are listed first. Also search for those keywords as well. The more results that show up with those keywords the less likely a sale.
because we can't look into your portfolio here, no one can give you exact advice on how to sell more of your photos. This way you only get general tips and hints which can be found in the Adobe User Guide, which of course should be read by every new contributer.
If you would like to have special advice about your photos in the portfolio, you can publish a link here and get the opinions of other providers.
In general, you should be patient, because the sales won't arrive overnight. This depends very much on the quality and number of images in the portfolio.
