I'm a newbie too. (<1 month) I loaded about 40 photos initially, added keywords, etc. Then I acted like a buyer to see if I could find my own photos and if so, would I buy them. I found that my photos were lost in the millions (i.e. tree silhouette during foggy dawn, old farm equipment at sunset, dog with ball) of similar photos. So, instead of trying to get noticed by shear volume, I decided to hold back and develop a unique sense of style and perspective that might be marketable. So, I'm not discouraged. I'm going refocus, so to speak, and work on marketability versus me-too.
