what is semantic markupLast week, Google helped to advance the internet in another giant leap forward as they announced that they would now be making use of semantic meta-data in their search results – specifically in the form of a new kind of search category for recipes.

Recipes?! Yes – users of the US-based Google will now notice a new Recipe button in the usual sidebar search buttons, alongside News, Books, Places, Images etc. Clicking on that will give you a special view of search results, which have a small preview image, show user reviews and ingredients too.

What’s so amazingly cool about this? Why should you care?How will this one step change the internet forever? Read on to find out exactly why this matters.

What is Semantic Markup, or Meta-Data?

Meta-data is a difficult concept to grasp, but let me try to explain it simply. Meta-data is that which describes other data. So for example, here is some regular data:

(+44)208 234 5678

Of course, most of us will recognize this as a telephone number, but computer systems have no way of knowing that. They see it as a string of numbers – it could be anything! So that’s where meta-data comes in. For example, how about if I wrote it like this:

<span class=”telephone”>(+44)208 234 5678</span>

Now I’ve surrounded this in meta-data – semantic markup. Any system that knows what the “telephone” tag is can now correctly interpret that the number is indeed a telephone number, and can do with it whatever it wishes.

So…what? What does that have to do with recipes?

Well, as I mentioned – Google now uses pages with semantic markup (or what they like to call Rich Snippets) for the new Recipe view. What this means to you and I is that we can narrow down the search for a perfect recipe much more specifically and accurately by making use of this meta-data. For instance, searching for “thai food” will initially give you a huge list of random Thai recipes, which is nice but you don’t really know much about the recipe until you click through.

Now suppose we really want to make something with Tofu in it. You might add Tofu into the search term, but it’s not ideal. Instead we can simply check off Tofu – Yes from the ingredients list, which will narrow the search to all recipes that include Tofu in their meta-list of ingredients. You can also check off any ingredients you don’t want, like so:

You can also drill the list down by using the “less than preparation time” meta-info. There would simply be no way to do this with regular search, as putting “15 min” in the search would only find pages with that in the text.

In short, having web information marked up with semantic meta-data gives meaning to the information, and allows us to make use of it in new and exciting ways, as well as allowing us to find relevant information more efficiently than simply text matching.

Google IS Good Sometimes:

I’ve been a little harsh on the quality of Google results lately, but this single step is going to change the way internet pages are made forever, and I applaud them for it. In a nutshell, Google has single-handedly forced internet publishers – at least recipes publishers – to use meta-data in their internet documents if they want to be listed in the search results. Sure, it’s only for recipes at the moment, but eventually Google will roll this out to many kinds of search. In fact, they’ve already published guidelines for how to mark up:

  • Reviews
  • People
  • Events

Everyone, meet the Internet v.3 – now there is meaning to all that random data!

Further Reading:

There’s tons to read from Google about Rich Snippets, and they’ve also released a useful little tool to see how your webpage is doing right now in terms of Rich Snippets that will be used in the results. Next week, I hope to be starting a series of WordPress How-To’s where we’ll delve a little into the code behind WordPress themes, and I’ll you specifically how to add some of this rich snippet data into your blog.

You can also read about all the different “microformats” standards that are being developed as you read this over at MicroFormats.Org. Though all of these are not implemented yet, you can be sure that if you make efforts to add them now then you’ll be in good standing when Google does roll out the next changes.

    I think this is a great move by Google and should help increase the gap between content farms and useful resources. It's the next logical step in the *cringe* MVC model. Initially, it's going to require more code and more overhead in the simplest data form, but then that data actually MEANS something, which is worth the cost.

    In addition to the Reviews, People and Events you mentioned, Google also recognizes products and breadcrumbs. Breadcrumbs is an interesting one because it's so generic, but it helps Google to better understand the organization of your site.

    Looking forward to the WordPress Code for Rich Snippets.
