Thanks in advance for reading this brief post. In the past, I've created a niche publication (free) that helps marketers by examining how web hosting choices can impact their marketing efforts. I'm not trying to promote that. There's no cost, no paywall, no signup form. I AM trying to find other niche guides around marketing. I know some put forth niche information in the form of courses, like Ray's Fresh Bananas SEO course. If it was an ebook instead of a course, it would be a perfect example. Can anyone point to any niche guides to marketing, perhaps how marketing is influenced/boosted by things like photography, technology, social proof, paid promotion, etc?
