SEO is hot topic these days with lots of people trying to figure it out.
I just learned about a great informational webinar (meaning no sales) on Search Engine Optimization for beginners being done by Anita Campbell at Small Business Trends. Anita is well respected as a publisher and has on-the-ground insights to share with other small and medium business owners. I'm sure even large company execs could learn something, too, but her focus is often on small biz owners.
There will also be a TweetChat session for those who would rather just follow the commentary. TweetChat.com is the service I personally like, although you could use many others. If you use TweetChat, just use the hashtag: #SMBTOOLS.
