While you don’t need to be a geek to get a site up and running, getting a handle on the nuts and bolts of how a site functions can be an empowering experience. A great way to understand how a web page is created is to go to your browser’s top toolbar and go to View > Page Source in order to see the actual code that the browser reads to display the page.
Why does this matter? Search engines read code too. When a site is deemed search engine “friendly”, it means that the keywords that someone has entered into a search engine (such as Google) are easily found by “bots” that scan web pages looking for keywords that match. Sites that created with clean, easy to read HTML are easier to scan, and easier to find.
