I am a newbie to Stock and I was wondering if vets had some hint on how to improve sales.

The ones I can obviously think of:
1) produce salable images
2) apply proper keywording

What else helps?
Promoting on other website? ( I saw a post of someone who posts on flcker and links to their iStock portfolio)

I don't have enough images produced or accepted yet to make an impact, but I want to plan.

Hi
I see the term Return Per Image ( RTI ) used.  Is this image uploaded, or images in my portfolio.

As an example, I have 258 images over 8 sites, but most are the same 95 images.  Is my RTI calculated on the 258 number or the 95 number.  ( actual for me the answer will be 0.00 since I don't have any sales    )

I know it will take years to grow, but I just want to know what stick to measure myself against is...
