RDFa / Microformatting:
This is hands-down, one of the most important things you can do for your website. You’ll be way ahead of the curve – and see much better local search results for your business and better indexing of eCommerce products.
You’ve heard of Web 2.0? That’s so 2008. (All kidding aside.)
Web 3.0 is known as the Semantic Web. To the end user, there’s nothing different when they visit a website. To the Web developer, it means using special tags inside the HTML code on a website to let other websites understand what is being described on the page. When most sites adopt an RDFa or microformatting on their websites, it will allow for much more powerful aggregation of content and more reliable search results.
Why RDFa / Microformatting?
Most websites are designed to be used by humans. If done correctly, a search engine or eCommerce aggregator is often able to spider through a site and index the content.
But some things that are really easy for humans, can be particularly difficult for machines to sort through.
For example:
* What is the price of the item?
* Who is the manufacturer?
* What type of product is this (i.e. category)?
A human can identify these easily. A computer trying to sort through the long strings of content on a website cannot. RDFa microformatting tags can help.
