Over the past two years I collected quite a few PDF and other downloads about social media in general, blogging, social media marketing and SEO.

While blogs offer quick tips and overviews ebooks and white papers have the necessary depth to cover more intricate topics.

Ebooks are particularly apt for the quite abstract concepts of social media marketing and SEO. That’s why I compiled this list of 25 free social media marketing and SEO ebooks, white papers plus other downloads.

These downloads stem from highly respectable sources and are free as agencies and specialists tend to promote themselves showing off their expertise for for free to gain recognition as experts. So this is a win to win situation for the sides, you the reader as well as the authors.
