Collect build a content marketing "lexicon"

Hi! Internet is full of advices related to content marketing. I would like to gather the most important advices in a database and I need help to collect them. They should be split in categories: Facebook, Instagram, Twitter, Adwords, SEO, customer persuasion that work online, Copy writing, e-mail marketing plus some other obvious categories tha I might missed. Usually 1-4 sentences pr. advice or description are enough. It should describe both technical terms like Facebook Pixel and best advices on how to give better response on an add. Maybe someone allready have lot of information stored and like to sell it, or tools that can gather it from internet in a smart way. Feel free to choose your way to collect it. I would prefer that it is sorted in different categories. This information will only be shared with my top customers, not free online. It will be translated to Norwgian. Prefer someone with good English knowledge.
