Benefits of Hcards in SEO
An hCard, similar to a vCard, uses XHTML to allow search engines and other bots to decipher between a random text passage on a website and an address, phone number, website, etc. by simply adding a few extra attributes to a websites XHTML. Since addresses appear all over the web without any unifying structure, this works to tie them all together with one consistent syntax. By using a consistent syntax, tools such as Google Maps’ API can pick up on these things much easier, while still providing useful markup that humans can read and understand easily.
So why should you start using the hCard format? Like most SEO best practices – for the limited amount of time needed to make the necessary changes and the possibility of future adaptation and acceptance, it can’t hurt.
To make your own hCard today, use the hCard creator. Make sure to note the warnings on the page as well.
