I’ve been online since the early 90s and working on websites since 1993. I got interested in SEO as an employee at an IT support company. While employed there we realized that I was spending more time working on the website and less time doing what I was hired for. Instead of being a bad thing, this turned out to be great for the company.
A couple of years in I quit to start Local SEO Company and my former employer became a client. I have a thriving business, multiple customers, and excellent rankings for everyone involved. SEO changes monthly, sometimes weekly. There are hundreds of websites and people you need to keep up with to follow all of the changes. But it is a great job, and I genuinely enjoy the work.
