What is a good free seo tool that distributes widgets to embed on own pages?

Hi There
Been looking for a way to fill a blank spot on my pages with some seo widget or badge or banner , and if possible to also look good, not like the www.alexa.com banners, that are well know and not attractive at all.
Looking for good answers.
Thank you
