Greetings, What guides should I read?

Hello everyone, new member here. Curious about IM and would like to read some certified guides if possible. Did some looking around the forum but forums are always an enigma to pick through what is accurate and what isn't. If anyone/everyone wouldn't mind linking a thread that are basic guides for
-SEO
-PPC
-AdSense

or anything else worth reading that'd great! Not asking for you to teach me here, just looking for a simple links to threads on this site that are good guides for beginners. Thanks!
