SEO, or search engine optimization, is how websites are discovered by the search engines. It consists of many different facets including keywords on the web pages, how many there are, where they are placed, are graphics are optimized, how many sites are linking to you and much more. If you want your website to get good positioning, then SEO is a must learn process. Many of the tactics can be learned and implemented by yourself with a bit of practice. It's finding a good mentor that keeps up on the changes that is really important.
See, search engines need to constantly change the way they search for websites. That's because if website owners can figure out how they do it, they could "game" the system and get top rankings easily. Gaming is not how it's done. A complete and well thought out system needs to be established solely for your kind of site. Setting up long term strategies based on sound SEO principles will keep your site at the top of the searches.
Search engines may change the way the search for sites periodically, but the main system doesn't change. They just tweak it a little. And a good SEO mentor knows how to create different pages of your website that will come up high on certain weeks and some pages will come up high on other weeks when the search engines change their algorithms... keeping your site in perfect balance week after week. Trying to chase the search engines around with tricks doesn't work. In fact it can get your website banned. You need a well balanced and whole view of how you use SEO.
