Are you a Search Engine Optimization company or solo SEO and want to know the industry rate for online marketing? Payscale.com has a widget to let you see.
This company really tries to be tricky and insert text links in all the embeddable widgets. It looks like payscale has its own search engine optimization firm and they are helping spread the links online. Unfortunately adding individual salary listings is cumbersome and not very user friendly, especially in the wordpress editor.
