I attempted to look these up online before I asked the forum but I have not been able to find a solid answer (usually brings up something unrelated). I have been studying SEO to learn it for myself because of so many people BSING about how they do this that and the other. WACK! lol When it comes to Adsense and SEO what does the follow mean. CPC? CTR? BACK LINKS? SITE MAPS? LINK BUILDING? PR UPDATE? if there are any other major "lingo" I am missing please feel free to through it out there.
