Papercupco - Profile

I have been on siteexplorer and SEOmoz but I was only able to use it 3 times free as it is asking for me to pay for it now.

Does anyone know any free tools to help me do SEO on a website about printed paper cups which has recently been redone?

We make our own videos in-house and then upload them to our Youtube channel. We have found video testimonials to be great and we have had a lot of views since they were put on our website The Printed Cup Company. We don't have the budget to pay anyone to do these videos for us at present, we are happy making our our videos at present but we could do with adding a new video a month and getting some new ideas!
