Do I need a divider here?

Is that okay to do or should I put in a clear divider between the ads and additional links?

 

I would have just done a little bit more gap.. That should do. I would have also aligned the links below the link unit to same alignment.

 

I see a lot of these. Won't do it myself. Most bloggers have trained their eyes to avoid the ad links. If you put it in a separate box, it'll look better.

 

It's not a blog. And so far revenue is up.

 

You have that AD in your links box. I believe you are violating tos. The ads should be in their own box, maybe "sponsors" or at least away from your links.
