Is this ok?

I have just read various sections about Google adds and it seems that 336x280 is the best ad to have under the navbar.

I have now added this to guests only here--> http://www.chatfootballforum.com (front page) http://www.chatfootballforum.com/forum.php (forum)Do you think thats ok?

Is there anything else I should change or anything as im not great with the google adds really.

Sorry for another post, but a quick question can you use the same code elsewhere on the site? I've done that a bit for one of my other ads.

Thanks

I am not great with ads, but I am pretty sure you can use the same code whereever you want on your website, but google limits the ads to three per page.
