Many non-technical folks are too nervous to try things that might be slightly technical. Search Engine Optimization is one of those things. It is not too hard to imagine that a person with no or little technical knowledge might think of SEO for rocket science. Basic SEO can be done by anyone, and I mean anyone who is patient enough to do the basic things. Fixing the structure of a page, changing the meta tags, creating contents that have a certain keyword density, can all be done by a non-technical person. Even keyword analysis, to a certain degree can be done by someone with no or limited technical knowledge. Should you do SEO yourself? It depends. While anyone can do SEO, the results might come later than sooner if you choose to do it yourself. Good Professional SEOs often no shortcuts to getting better rankings and traffic to a site, so if your site is mission critical and vital to your business, then you might want to outsource its SEO. If your site is just a hobby for you, then you can probably search optimize your site and have fun while doing it.
