This is my first question here so I take the opportunity to say hi to all of you!
I'm a mac user and a Seo student :)
At the moment I'm using several tools to check my progress on a particular website, like: senseo firefox extension, website grader, etc.
Unfortunately there is no SEO suite for mac like Webseo or IBP (actually there is one from link-assistant but I'm not a fan of it) to have all the results at glance.
Looking at the price of these programs do you really think they are worth it? Do you think there are any free alternatives especially for mac users?
