Can people please no-follow their Amazon links
It's easy to forget to no-follow your affiliate links. the quickest way to check is to put your sites through the following tool:
Keyword Density Tool
It's a keyword density tool, but lists all do-follow links on your site once it's crawled it.
Do check all your pre-2007 sites too. I'm sure there are hundreds of Amazon widgets on old blogs that are do-follow.
This is quite a big community, and I'm sure if we collectively no-followed affiliate links it could have an impact (well it can't hurt can it?)
