It’d be hard for Google to argue with this content not adding value. After all, some of the guides have received close to 10,000 shares and have been used by the brands themselves to educate their own customers. Generally speaking, each guide takes about 40-50 hours to produce, and is benchmarked to beat the best existing piece of content on the topic in virtually every aspect (from design and share-ability, to page speed and on-page SEO).
Next, you’ll want to pick a WordPress theme from somewhere like ThemeForest, Elegant Themes or OptimizePress. This is the barebones design of your site, which you can then customize with your own branding, copy, and images. That being said, you don’t want to cheap out. It costs less than $100 to buy a theme that will make your website look professional (and you can upgrade to a completely custom design once you get the business going).
