Sales and Marketing is around 60% of revenue at 47 million a year. Advertising is around 5 million a year, so the rest of the spend looks like sales costs, content production, and maybe event marketing.
The media spend seems to be mostly adwords: "The effectiveness of our online advertising has varied over time and may vary in the future due to competition for key search terms, changes in search engine use, and changes in the search algorithms used by major search engines."
Also, they only have 5000 FB likes - if they were spending $100k+ a month on FB these likes would be higher as a byproduct of the paid spend. I do a ton of B2B/SMB FB advertising, my guess is that they could move some spend to FB from AdWords and see better ROI.
