You were really able to explain very simply what an SEO service is and why such a service is needed at all. I would never have been able to explain it so simply. However, I slightly disagree with you about whether it is worth doing SEO yourself or not. The very essence of SEO is not only to increase traffic, but also to improve the site so that people would like to visit it more often. And to improve the site, I mean to improve the performance and visual appearance of the site. Everyone can do this on their own, of course it may take a little more time, but it will be more interesting! Everyone can order press release distribution services , but not everyone can do everything on their own!
