wisgrandma, run by Nancy Radlinger, covers the basics of online marketing from the ground up: setting up a blog properly, writing an email people will actually open, using social media on a company's behalf rather than as personal chatter, and running an article marketing campaign end to end.
The posts are organized rather than personal, each one a short guide to one piece of the puzzle: research your topic before you write about it, build a referral program instead of just asking for forwards, register your business name on Twitter and Facebook before someone else does. None of it depends on unique experience, and it reads as a competent overview more than a story.
What stands out is simply who is writing it. A grandmother working through blog creation, email campaigns, and article syndication is not the default image most people have of someone starting out in internet marketing, and that alone is worth noting even though the posts themselves stay in generalist territory.
Use this as a starting checklist for any of these individual skills, not as an account of one person's specific results.
