Have you ever been part of any SEO conference ? It happens here every now and then. Some of them are good, by reputed names. Some just need to collect attendence fee.
Most of the good conferences talk about busting common myths and introduce tools which people can use to improve ranking or analyse data.
Most of them are for taking your money. So are some webinars. But there is a good thing. You get to meet peers and learn from them. Improve your contacts and other benefits of meeting the community in person.
