HTML5 Microdata, Schema.org and Rich Snippets – Explained and a Free Tool
Author: Bob | Filed under: Build Your Website, Search Engine Optimization, Web Design / Development
Rich snippets are all the rage these days. Ever since Google started
enhancing their search results with these extra tidbits of information,
everyone is rushing to update their web sites with the metadata to
enable them. So what is the benefit of having a “rich” search result for
your site? Good question. Other than giving the search engine user a
little bit of extra bit of detail, I suppose there’s also a subtle
psychological factor that kicks in. Someone might be more inclined to
click on a search engine result that has a 5 star rating and a friendly
face than one that doesn’t. Plus, they’re just plain cool. Who doesn’t
want to add bling to their search results? But this only scratches the
surface. There’s much much more to them than that.
Instant information aggregation: It’s only a matter of semantics
Rich Snippets, as Google calls them, are actually semantic markup. The
idea of marking up some sort of document with meta information for the
benefit of machines is not a new idea. Semantic markup is as old as
information technology its self. For example, a Word document contains
metadata about its author, and a digital photo contains meta data about
the camera it was taken with. You might, for instance, store your
digital snapshots in a photo archiving program which uses this semantic
data to filter your photos by date taken, lens type, flash used, etc.
So, in essence, metadata is data about data.
It’s should be clear, then, how this “data about data” can be extremely
useful to search engines. It can provide a search engine the ability to
derive a semantic meaning from a document’s meta
information rather than having to rely purely on the abstract, human
understandable, concepts within the text of the document. Searches can
become less about keywords in text documents and more about
relationships between semantical data types.
To illustrate this point further, consider the following search: Find
all restaurants with a 3.5 star or better rating on the Las Vegas strip
that specialize in Italian OR Mexican cuisine AND are open after 11 PM
on Sunday nights AND do NOT require reservations. On the
semantic web, rather than a list of links to restaurant web sites that
may or may not match your given criteria, you might get a list of
“restaurant result objects” that DO match exactly
that criteria and never even have to visit the restaurant’s web site.
This is where the real power of semantic data lies. Instant information
aggregation.

This “semantic web”, also, is not a new idea. In fact, Tim Berners-Lee
himself envisioned the world wide web as a kind of “Semantic Network
Model” and even the earliest HTML specifications included the concept of
meta tags, which you are undoubtedly familiar with. Later iterations,
such as XHTML, took this idea a step further. Most notably is the RDFa
specification, which has been around for quite some time.



















Start by making all your links absolute and getting rid of any secondary keywords that are irrelevant. As your pages mature, you want to make sure that they have names in the format of http://www.yourwebsite.com/pagename.html. That causes your pages to boost each other in the SERPs, and ensures that if your content is copied, the links will point back to your pages, giving you another back link (hooray!).
It’s also important to remember that keyword stuffing isn’t good. It’s one of those cases where less is more. Keep it to the basics of once in the title, again in the description, and a few times on the page. And once in your h1 tags.
