One month into the Greenlight, getting to the top 100 is extremely difficult without major marketing (pay marketing companies to help, or joining a bundle giving away keys for 5 cents). Some other devs even do shady crap like bribing for votes, giving away gifts/keys etc on Steamgifts/trades.
Looking at the stats for other titles on Greenlight, even really good games that don't have marketing to drive visits to the page struggle.

Tracks all the titles on Greenlight, it's accurate.
It seems the natural traffic from Greenlight itself is falling over time, now the first few days, natural viewers seem to be around 1200. If you can secure 50% of them as yes votes, that's already quite good, due to people liking different genres. But besides that, if you want more visits to your page, you have to direct them there somehow.
Good learning experience so far.
