I have a trading/investment site that's been up for a few months now. It gets about 30 uniques a day and earns between $1-2 per day. CTR is about 5%. The traffic is 80% from search engines (mostly google), and the rest comes from a couple forum links. I'm just wondering where I should concentrate my efforts to get more traffic. Where could I invest the couple bucks a day from adsense to help the site grow?
I would work on more links to the site. You can also use some social bookmark sites for more traffic. You can buy ads on clicksor and adenage but if site has adsense on it i would not. Some sites might have publishers with paid sites and adsense will bann your site.
If you want to get listed on more search engines then try Dequba out It's free to join and they have a search engine that you can advertise on, plus many other benefits, If you pm me I can walk you through how to get your advertising set up through DeQuba, its really easy, just like other search engines you include your site, then your key words and how much you want to spend for each word. Mind you it won't cost you a dime in order to get listed, and or get started.
You should concentrate on writing some really cool content for your site and try to get the larger blogs to link to it. What is your url? I can probably offer some advice.
