Who it is for
People who look after their own website and want it found: a shop owner, a freelancer, a marketer in a small team. You do not need to know any code. Each issue takes one idea, explains it in plain language and ends with something to look at on your own site.
The lessons build into series, so over a month or two you cover a whole subject: first the parts of a page you control, then how search engines find and store pages, then how to choose what a page is about. If you would rather start at the beginning, the On-Page SEO series is the place.
Subscribers also hear first when a series becomes a free guide.
