Web 3.0 is the third generation web. It is a way for people to be more connected. You are able to connect to the Internet where ever you are. Whether you be at your house, at school, or even in your car. You are able to be connected with others. Businesses like Web 3.0 because it is a way for them to personalize information for customers. It also can be like a personal assistant because it retrieves information for you and it offers suggestions that you may not have thought about yourself. Web 3.0 is more contextual which means that you are able to search for things using a phrase or keyword and it will be able to understand. No two people will have the same browsing experience. When you type something in a search engine and someone else types in the same you both will get different results.
