Are you slowing, increasing, or maintaining marketing

[Seth Holland]

I'm having trouble with the ROI on my marketing as we (I feel) near the top of the market. Everyone knows good deals are getting harder to find even if you change your strategy up a little. So the question becomes, are you decreasing, increasing, or maintaining your marketing budget while we near or hit the top of the market? When does persistence become irrational? I've only been in this game for 2 years so I've never seen marketing work on the down slope of the market.
