A Couple Returns to work as a Web Master Team 10 years later

Hi Guys! We are Alexander & Kate, Web Dev, and Designer since school time. 90'

We worked elsewhere and now we are back in programming and graphics. Passion and ability are not lacking, but restarting isn't easy. We became digital nomads in Europe because tourism jobs with fast contract deadlines kept us to a minimum profit. (now with covid19, tourism is in a BAD WAY).

Last summer 2019 we went into the freelance world as a full-time digital worker. We started to make xxx,oo$/month after months, from various freelance platforms about design. But we learned to stay away from many dangerous Scam Marketplace, they steal your artwork and keep your money! I won't tell names for privacy, but we do it for the nice revenue place only as: Fiverr, Amazon Turk and Freelancer.

Since the beginning of 2020 I have been dedicated to 1amazon affiliate website that is making less than $10 p/mo. Amazon asked me to change the disclosure and reactivate the account from zero, everything ok until I redo for the 2nd time the "3rd sold item" for the review of the site. I do 1 post/week but the main source of clicks on the associated site are social, which generate sales, thanks to my wife as social media marketing makes 100followers /week. Now with yoast ahref and similar, I am trying everything to like at google eyes and He will increase the serp rank for me. I hope to don't miss anything because I'd like to sell my site to $ 2/3k as soon as the view rises.

So we would like to receive advice and share experiences like before! The trouble is that we would like to have more revenue in a short time, as everyone obviously ! But luckily we know that here is full of people more experienced than us.

Can we start with 1 easy question? THAAAAAANKS!

What about If we open 1 + 1blog + 1vlog to increase the keyword on our Portfolio sites?
We know that the vlog on youtube makes much revenue by CPM higher than the classic banners of websites, and of course, the time to make 10 min videos require less effort compared to a 1000word article well written!

Thanks for reading and for your kind answers!
