Which page on your website is the homepage? Simple enough question, right? Well, maybe not. Most businesses think their website does a pretty good job of communicating what they do to customers, right? However, they're assuming that every visitor enters the website from the front door, the homepage. Except that's not usually how it happens. Most visitors come to your site thanks to search engines, not thanks to you. And search engines don't give a stuff about home pages. You don't get to decide on which page your visitor enters your website. Google and the rest are deciding which page on your website is the "home page" for the visitor based upon the search terms they've entered. It means that every page on your website needs to be strong enough to stand on its own. It must not rely on the visitor stumbling around your site and finding the information that they want by accident. There's no place like home, wherever that may be.
