The web as we know it is just a basic version of what it could be. It represents unused potential and the future looks bright. The future is a change from the HTML format that the internet uses today. With the HTML format, the internet is very limited as far as what it can do for the user. Using a search engine with HTML you may have had a hard time finding things. Using Semantics, searches would be much more relevant and return more of what the user is looking for. The way semantics works is more through tagging the content of a site by its meaning. The way site builders can do this is through structured data and linked data.
Structured data is when a site lists contact information or anything like that that can be recognized by a search engine and returned to the user. Google has already been experimenting with structured data in searches. When you search something in Google and the links that pop up have information from the site such as a phone number, location, or other information, you are seeing structured data.
In the image to the left, structured data is shown about Rihanna, the search topic, to the right of the search as well as the image and information about the first link. The more structured data a site offers, the more relevant hits and traffic it will receive. WordPress is a great way to look at structuring data in an easy way. They make your content easily accessible and searchable in a relevant way.
Linked data is a different way of structuring data. When someone links data, they are showing a different relevant site through a link in their site. This is like structured data in many ways in that it shows the user what they are looking for, which is the main idea behind using Semantics over HTML. As we shift closer towards using non-basic markup language, the internet will become a more recognizable place for machines, which benefits users. The more the machine you are using can tell what you are really looking for, the easier it will be for you to find it.
