I have also a 30-35K monthly pageviews niche blog and my experience says that is very difficult to monetize a website like this. I never made more than 90€/month (including all sources of income) with an average of 60€/month. Anyway my two cents are: - donations: forget about it. Before put ads up I tried paypal donations. That only got me $5 despite remembering readers about it every couple of weeks for 5 months. - ads (adsense): ugly and annoying but is the most important and stable source of income my blog has. 80% of all income. - amazon affiliates: margins are low but with some work (and luck) you can get a decent source of monetization. Probably depends also on your niche market. 20% of my blog income. - email marketing: since recently I have been collecting emails but didn't use it yet. Anyway my market target is mostly students so the potencial income will be low.
