"... pages in prototype/without downloads will not get added into the search results"
- Good to know. Thanks about that info!
"I guess one way of seeing is that if you would know it too exactly it may be abused? "
- Not sure if it would because Steam also has uncovered a lot about their algorithm and I guess it could be misused bit it's still very limited. Like games that are of very low quality will not get very many players even if they stay in "Popular" tab for weeks (at least that's my theory). You still need some substance to attract and retain players, good thumbnail, reasonably well crafted page to let the players know that you took effort into making this.
