I really like numbers 3 and 5. A couple of the others look a little sloppy but those are nice and clean.
They're all way too busy, but #4 is particularly bad. A good logo has to be simple enough to reduce down to small sizes without losing its distinctive appearance. And it has to work without colours or shading so you can fax it and use it on swag. Think of the future. Colour printing is expensive and there are many occasions when it will not be worth it. By choosing logos like these, you are needlessly increasing your marketing expenditures. But really the biggest problem here is that they are ugly and clearly produced by someone totally ignorant of typography.
I like No.2 on a light background best. There is an error in your slogan "will" should be "with". If I was you I'd make the slogan shorter, perhaps; "Quality website traffic"
My favorite is the second one from the top. I'm not real crazy about it any of them, but I went into your link with the idea of seeing which one stood out the most, it was definitely the second one from the top that caught my eye. The downside to this one is that I didn't see the word "visitors" until later. Since this is included in your URL, it may need to be able to stand out a little bit more, at least. I would change the color to the blue to accomplish this.
