So... search engine optimization? On other sites like Envato this can make or break your clip that you're selling. So does anyone have any knowledge on how does P5 search engine work? Does it look for the file names related to search terms first, or tags? Do the freshly added files get shown higher in search results? Lets figure out what we know!

From what I've noticed, files with a relation of highest views/sales get shown first. I might be mistaken, feel free to share your own findings and analysis results.

I knew one fellow, who said you live and die by it. I am starting to look it more carefully.
