So - this creator has a lot going for them, but one of the biggest takeaways here is to provide value. This may not apply equally across all niches, but one thing to keep in mind, is that if you can provide value based off of your experience, then you absolutely should. These thumbnails are really good, and the titles are really good, but they're also really different. The question then becomes, what is it about this content that resonates so well with an audience. The answer? Value. Highly searchable content will be popular years after upload, and someone wanting to have a basic course can still search this as time goes on. Even if the technology ages out, it still might not matter as guides/tutorials/walkthroughs/courses/tips+tricks always tend to do well long term. Takeaway? You don't have to switch niches to provide value. Whatever your niche is, consider adding a tips/tricks video, or a course structured video to your content pillar format. Don't know what a content pillar is? just ask -I'd be happy to walk you through it
