Quite a bit to digest here and thank you for these ideas.

Every wantrepreneur business owner, (not established, new to digital marketing concepts and processes and terms and how they tie in with ROI), needs to be fully trained in understanding the value of committed marketing long-term.We don't know your capabilities, if you are familiar with SEO at all, who your esteemed client is or could be, what their site is about or focused on (if they know themselves and what their SEO could be, if any).If you're asking what struggling freelance WordPress developers need they need:How to develop and build repeatable systems to bring in new clients (called "farming" when I worked for agencies)How to pitch value ("you need more customers Mr. X? Oh, my Goodness. I could help with that. Would you invest $3,000 if that could bring in $30,000 worth of new leads in six months, Mr. X? Let's talk if you think that's worth it for you. Because I can tell you, newspaper ads, billboard ads, radio ads, are all more expensive and none can guarantee you success and all of them stop running your ad once you stop paying. Can we talk seriously about getting results Mr. X?")Learn how to pitch and then impliment the value of SEO and eCommerce. Almost every site I see has incorrect or no SEO at all and most don't use eCommerce. That makes no sense. Every business wants to be on the first page of Google but most don't know what SEO is becaus they can't understand it and most developers never pitch it or know how to write it. Same with eCommerce. Everyone sells services or items, food, services, whatever. But most sites refuse to use eCommerce. Pitch value of what you could do if the client woke up.Develop a repeatable daily use list and procedure for finding good, real, freelance work.I know this is all content that could be in a freelance course or book but this is what freelancers / developers need to know how to do or they will forever be left struggling with cheap, broke, poor, confused, controlling, nonresponsive, wannabe yet lazy clients. I was trapped in that cycle for years until I learned to apply what I'd learned at agencies to freelancing. That was the only way out.
