Although I’m not sure, I’m guessing volume of sales?
An idea would be to run a blog in the lines of the product you sell. Maybe some tutorials on CSS , how to code etc. It’ll start generating organic traffic and you can put links to your products. Also, you can start earning passive income using advertising on the site.
Sadly, we can only control font smoothing from the OS/browser configs. I’m facing this very problem right now. Using a fontsquirrel font and it looks like shit in small size. Dont want to use sIFR/cufon either. Damn !
That is the estimated sales. Based on how the item has been doing in the marketplace, envato estimates the sales and earnings. In your case, that particular item ‘could’ generate 6 sales per month and make you $18 per month IF the sales trend continue as it is now.
