It's impossible to say if it's enough without more details... 10k would be awesome if I had a 10% conversion rate on a product that profited me $100 per sale. It would, however, suck if I had a 1% clickthrough rate on that same traffic with a 3 cent adsense ad. It's all relative.. And, on a side note, there is no such thing as 'enough' in my book...
