You do have an ambiguous description - so my answer here is very general. Feel free to e-mail me (see my profile page) for a deeper discussion. My instinct is that you are getting a decent amount of ad revenue, and that you might be able to get more - but it will likely require a whole bunch of experimentation to figure that part out. I would instead focus on the other opportunities: driving more users, and generating other forms of revenue. You likely will be able to 2-4x your users by experimenting with SEO and Social traffic sources. Also, 2M page views means you likely have a lot of users that you can try to get them to interact with the site more - that interaction will likely result in them coming back and getting more users (via) facebook. With regards to revenue your simplest bet could be with thinking about different affiliate programs - you might want to approach relevant companies even though they might not have an explicit program. If you have a specific niche of users, then you can likely drive up ad revenues more, but even if not you can try segmenting your users giving them a little more reason to stay and finally targeting them differently for higher ad rates.
