Hey that is a really nice site.
Its very bare as in terms of ads which is probably why you are not making that much. For one thing, its a quality site if that content is 100% unique so the last thing you want is to spoil it by going mad with ads.
Ever heard of affiliate program
Chitika? If not go check out if your country is supported and join up if it is.
Do you follow
Problogger at all? Make sure to read though Darren's blog, he is right in your niche with the
Living Room. He gives out some great tips on Adsense and chitika, among other things.
Is the majority of your visitors repeat visitors? If not you could be missing a lot of bounce traffic. These are the people who stumble into your site and jump back out again probably trying to find a specific thing. The majority of them will come in from a Search Engine and do a quick scan looking for that info either on or off your site.
Your regular visitors are not likely to click your ads anyway. Their purpose for being there is catching up on what you have added until moving on to their next favourite site. Even know they don't pay the bills they do bring a lot of value to your site. They make it look busy which gives the site a buzz and in turn attracts popularity.
Look at your traffic stats and find out where people are coming from, what % are repeat but also what pages are the most popular.
More importantly study Problogger.net from the start. I don't think anyone could advise better than Darren as I said, he is in your niche.
