Hi Prizelud,
Welcome to the forum.

Not made any money with adsense, gee.

Are you getting much traffic to your sites from search engines, or better yet, are they indexed?
I took a look at your site in your post, I notice there's a few things you could do with this.
Firstly, your link text unit, top left corner. Make the text links black so they look like your left navigation menu links - so they blend in.
Your title text <title> tags, take out Find Biz Info, and home page and leave the rest in there: business marketing information
In your keywords meta tag, take out these words: business , marketing , information.
They're not really needed because you already have them: business marketing information. Use that only. This will increase the keyword density of your meta tag.
Here you have your H tag, <H1 align=left><FONT size=4>Instant Business Marketing Information Strategies Any Business Owner Can Use</FONT></H1>
change that for this:
<H1 align=left title"Business Marketing Information"><FONT size=4>Instant Business Marketing Information Strategies Any Business Owner Can Use</FONT></H1>
Notice I added the title attribute there next to align=left
Also, take out your meta description tag, it's not needed, allow the search engines to pick out the paragraphs as needed, by having the meta description tag there you are reducing the potential visitors to that page.
I see you have a large square adsense unit, swap it for one that only inserts 3 ads in there. These pay more.

Don't forget to add these in your header tags
<meta http-equiv="pragma" content="no-cache">
<meta name="abstract" content="INSERT YOUR KEYWORD HERE">
<meta name="resource-type" content="document">
<meta name="distribution" content="global">
<meta name="robots" content="index,follow">
<meta name="googlebot" content="index,follow">
<meta name="msnbot" content="all" />
This not only allows most search engine bots to visit you, but also informs them what your site is about.
Where possible, in your articles, hyper link one of the keywords there to one of your other pages, and use the nofollow attribute on each of your nav links except for the home page. Then on the page that you linked up in your article, that article page, remove all except for the page file link itself.
like:
home page
article page 1 = nofollow
article page 2 = nofollow
article page 3 = nofollow
then on the article page 1 page,
home page
article page 1
article page 2 = nofollow
article page 3 = nofollow
Then on article page 2 page,
home page
article page 1 = nofollow
article page 2
article page 3 = no follow
Then on article page 3 page,
home page
article page 1 = nofollow
article page 2 = nofollow
article page 3
and so on, what this does is that it doesn't assign a page rank to that page. For instance, if your home page is a PR5, it will ONLY assign a page rank to the page that doesn't have the nofollow attribute on the hyper link. When that page is assigned a page rank, it'll more or less give it the same value of PR.
This reduces page rank bleeding and increases the full potential assignment of a page rank to the pages that you want.

Then go off to social bookmarking sites, and add your pages to those places. I've got a list of them that I'm going to put in my ebook, hope to have it finished in about 3 weeks or so that talks about this and a lot more. Once I'm done with that I'll start building traffic to this forum.
Hope this helps.

All the best
Loz
