What Are Some SEO Tricks You Utilize?

I've recently been asking a lot of different experts about their SEO tactics and it seems many of them use the same core vitals, but when it comes to little tips and tricks all of them had their own preferences. I actually just looked through an article about SEO That Works and one of my favorite tricks I've learned is hiding keywords in photos through optimizing images, now it may seem pretty day one but I see sites that you can clearly read how they are stuffing keywords and making things sound unnatural. So I wanted to ask what are your favorite or interesting SEO tricks?
