We’ve just launched a free social media analytics tool. It’s called Pythia.

The free version of Pythia measures your marketing campaigns based on several metrics:

• Links pointing to your site, according to Yahoo!.
• Pages from your site in the Yahoo! index.
• Links pointing to your site, according to Technorati.
• Posts mentioning your site, according to Del.icio.us.
• And mentions of your site on Bloglines.
• Changes in all of these metrics, over time.

The paid version also adds:

• Site ranking for specific keywords.
• Changes in rankings over time.

Pythia doesn’t re-invent anything, nor is it revolutionary in the data it collects. It is, however, a great dashboard, and one of a very small handful of tools that collect and save these metrics so that you can see changes over time.

I’m very excited about this tool. I could prattle on, but instead, I’ll let you see a sample report page and say ‘go try it’. I invite any feedback you’ve got.

Here’s what it looks like:
