Less than 10 searches, but it's bringing in money

Inspired by the warm reception of my training videos within wealthy affiliate I decided to create a new course and publish it on udemy.com. I checked on Jaaxy using the search term "gutenberg course". Dang! Less than 10 searches using that phrase.
But I knew I was onto something. Even if no one was interested now, I knew that people would want to learn more about Gutenberg as the release date approached. So I planned the course and submitted a test video.
For the first course I did for udemy.com I had to submit a test video four times before I got one approved. I've learned a lot since then and this video passed with flying colours within hours.
There was only one other course on the same subject at udemy.com, and because I figured my course was better I priced it slightly higher than the competition.
To give the course a jumpstart I gave out a few free coupons hoping to get some five-star reviews. Thank you friends. Every review counts and every star counts. This is the way that new students determine which courses they are going to take.
11 days later the course is attracting new paying students. But not through my efforts, udemy is finding the students for me. This is almost passive income. Promotion is not my strong suit, I much prefer creating the videos. So having udemy find students for me is awesome.
I'll keep updating the course as changes are made to Gutenberg. So it's not completely passive income.
The videos at udemy.com are different to the videos I've done for Wealthy Affiliate. If you haven't seen them already, the WA videos are:
WordPress Gutenberg: Create a New Post using WordPress 5.0 Gutenberg
WordPress Gutenberg: Add Headings to Your Post using WordPress 5 Gutenberg
WordPress Gutenberg: Add Images to Your Post using WordPress 5 Gutenberg
WordPress Gutenberg: Available Blocks in WordPress 5 Gutenberg
WordPress Gutenberg: Add Links to Your Text and Images
WordPress Gutenberg: Other Common Blocks
WordPress Gutenberg: Formatting Blocks
WordPress Gutenberg: Embeds and Videos
Now I'm looking for bright ideas for a subject for my next udemy course. What would you like to learn about?
PS I still have a few coupons available, you can contact me by private message.
I really think you are fantastica creating all these clever courses and videos, such a help for all of us.

p.s. I think you missed my meeting with Michelle and Loes, here comes. Happy Meeting with Michelle and Loes, a special Holiday
I'm looking into the Sitemap: AIO SEO, Yoast, & Google Search console, Child theme, and the custom CSS training. I have to say the child theme and the custom CSS are too advanced for me right now but I will spend more time on them in the future. :)

Honestly, I think if I had to pick a topic that keeps aggravating me, it's finding a theme. How to pick the right theme. What are the best themes for different niches like health, etc.
It's so frustrating to pick a theme and then discover that it doesn't do what you need it to do. Then have to go chasing down plugins, which can cause more problems. That may be too much to cover in a video course. I don't know.
Thanks for all of your training Marion. It keeps me sane. :-)
