Hello! Digital marketing agency owner with clients that have a variety of industries here with my recommendations based on what works for our clients.
With Google they love content. So regardless if you are backlinking to specific parts of the content or not, given time you will start ranking for keywords within the non gated content. Just ensure you have at least 2k words on the home page and at least 750-1k words on the other pages and you will rank no issue with some quality backlink strategizing. When you do come across backlinks that will work for that nongated stuff you can still add them in without causing issue. Hope I answered your question.

In my experience, for non gated content, going back to the basics works best.

Brainstorm all the keywords you want to target. Use tools to figure out how easy/difficult it is to rank for them. Place them strategically.

Making your content concise but highly relevant works best. Try building quality backlinks and don't forget the internal links.

Study semantic SEO and learn how it works.

Hope you found the answer useful. If you have something to discuss, feel free to talk!

Hi Amer, Pillar articles + concise course pages are a good method. However, the concise pages can also support your effort. They are the pages that can get the most juice for very specific keywords that umbrella under the top level keywords on your pillar pages. So on those 'concise' pages, you can go into deeper details about some of the underlying theory and interest points related to the video for viewers who want more on htat topic before moving on, and turn that into your primary page for that video's narrow topic. From the videos, you can interlink to each other in the deep content, and up to the pillar pages. I assume you're in good shape since it's been a while since you originally asked this, but I wanted to ensure you received an answer from someone. Hit me up if you have questions.
