People go online for millions of reasons but you can simplify this into three main categories: Entertainment, Information and Purchasing.
Now that you know why people are online you are probably thinking about how you can provide all three of these categories to a potential customer.
Information
Provide information to people it can be very simple or extremely complex. It is recommended not to just use text, add in photos and even videos when you can. The easiest way and the way we would recommend that you add video is on YouTube. The reason is that you can very quickly upload the video and use a simple embed code to share your video not just on your website. You can share YouTube videos on Facebook, Google+, put up a link on twitter, email it to someone and even more. The best part is that a video can be part entertainment and information so you saving yourself some extra work later!
Purchasing
I call this category purchasing but it is really much more that just that. It is being online for a purpose or to take an action. Many sites these days have added a form either to simply contact you or even more complex quoting systems or automated systems that will do things for you. This is the number one client internet marketers should be targeting and depending on your industry a great percent of these customers are doing mobile searches!
Entertainment
Entertainment is not easily defined because each person may find something else entertaining. Whatever entertains you and at least two other people will fall into this category. The obvious ones are somethings that is funny, a video, a picture, a game.
