Not exactly. Mostly what I'm doing with "SEO" is making sure pages show up correctly on each search engine, such as the text previews and what pages come up if you just search for my client's name. If you don't format your webpage correctly, it can look pretty bad on some search engines. For Kagi specifically, it seems to pull the appropriate content and text previews from my client's sites most often, if that makes sense.

Since I'm self taught and self employed I don't do any of the shady things (at least, I hope) that actual SEO community might be doing, and I definitely can't afford to "pay off" any company to get better results.
