Any suggestions to improve the search ranking ?

Good evening,
in your opinion what are the main factors to improve the ranking of your product in the search system of ThemeForest ?

What affects the search for Envato?

On other posts I read that are very important tags in the items,
but also affect

  • the title
  • The product description. Better SEO oriented to ThemeForest or just for Google?
  • Tags
  • Description in Images (not all author insert this)
  • Other factors (TF years, the level author)

What is the search algorithm, What affects ?
Any Suggestions based in your experience ?

Thank you so much
