Two Free SEO Traffic Websites
However There are wonderful SEO sites that have as much useful information as any paid course and provide free eBooks to download, as well as many other resources that are there for you to use for free.
A in my research experience, a few of the most notable are searchengineland.com, seobook.com, searchenginewatch.com. Of course,
Also I must admit that Google itself has some webmaster tools you can use to do direct research once you get started.
Thanks
