I haven't been able to give the site the attention it deserves, having no money to invest into it, and I've been focusing all my time on building up my website development company and doing work for clients.
Adsense pays out very little for this niche. It's almost pointless to have it there, but it's there for now since I dont have any other ideas.
What sort of things could I do (affiliate systems??) to start generating income with it? The site gets between 200-400 unique visits per day (all organic).
I've tried contacting amp manufacturers for advertising space on the site but had no luck.
Any ideas are greatly appreciated!!
