Google SiteMaps and You

A look at implementing Google Sitemaps, a technology developed by Google in order to help you define your site more effectively to the search-engine behemoth.

This is not a ticket to a higher Google ranking (at least not that we know about); but it is a useful tool that lets you apply RSS-like control to your website's interactions with the Googlebot.

RSS (Really Simple Syndication) is the current heavyweight of so-called "disruptive technologies" (loosely defined as those that have the effect, if not developed with the intention, of changing the way we use technology in general) and its use is skyrocketing among content providers looking for a way to get their content in front of more eyes and ears. But RSS originally stood for Rich Site Summary, a standard way of cataloging your site's content for third-party aggregators.

Google Sitemaps have a similar function, in that they are an XML-based way to describe website content in a standard, predictable way; but they differ in that Sitemaps are intended for the Googlebot's eyes only, rather than for any third-party. Think of them as an automated way to make sure Google knows about your site's content (please note, however, that Google does not guarantee inclusion of your content based solely on the presence of a Sitemap file).

This sounds like a very specific undertaking, but the importance of Google to getting your site's content noticed can simply not be overstated. And with Google's expanding reach into more and more areas of Web content presentation, chances are that you can be assured that the information your Sitemap provides will eventually find some use you haven't yet thought about. That's what disruptive technology is all about, and Google has become one of the more innovative champions of such technological advances.

Where To Start:

The first thing you should do as a website developer is create a Google Account for yourself or your company. This will allow you to do other things besides access the Sitemaps infrastructure; but we'll leave that for another day. Create the account here
( and then proceed to the Sitemaps area at (
Once you've logged in, you'll see the sparse Sitemaps interface. Don't be fooled, however, because like the simple interface to its search engine, this one hides quite a bit of information regarding the creation and use of Sitemaps, presenting it in digestible bites as you walk through the process.

There's probably more there than you need to know at this point, provided you don't have a huge site with a need for multiple Sitemaps and so on. But if you do have such a site, the information is there for creating truly complex Sitemaps and Sitemap Indices referencing many Sitemaps and you can familiarize yourself with that as needed. For now, we'll concentrate on what's required to establish a Sitemap for our site at Cafe ID (

Like creating RSS feeds, creating a Google Sitemap is as simple as putting together an XML file at the root level of your site that describes the site according to the instructions that Google has laid out. You can use any text editor for this purpose, but some editors do a better job of helping you create properly formatted XML files. We heartily recommend two that cost money, BBEdit on Mac OS X
( and Macromedia's Homesite on Windows (, but there are excellent free alternatives out there and when it comes to text editors, personal preferences take on an almost religious importance, so we won't proselytize about that here.

The Googlebot recognizes several Sitemap formats, ranging from a simple list of URLs to Sitemaps already created using something called the "Open Archive Initiative protocol for metadata harvesting", a format apparently popular with library collections. The OAI protocol is an advanced XML specification that you don't need to worry about if you don't already understand. An intermediate XML format is what we recommend, over the simple URL list, because of the additional information you can associate with each constituent URL of your site.

If you do want to just get started quickly, simply create a text file that looks like this:

making sure that the file in question does not include embedded newline characters and uses the UTF-8 text encoding (check your text editor settings). Also, your sitemap may not contain more than 50,000 URLs and all URLs must me fully-formed since they will be used directly during the Googlebot's crawl.

Getting Fancy:

The more advanced format isn't much more difficult to create and lets you specify additional information about each URL. The protocol is described fully here ( and is too detailed to explain here. Your finished file will look something like this, except (hopefully) with more URLs specified:

Your Sitemap's location dictates what URLs can be included in it. A Sitemap placed at the root level of your site can specify any URLs on that site, while a Sitemap placed at can not include URLs under, for example.

You can take as full or as little advantage of the availability of the various additional XML tags available in this format. Each needs to include at least the specification, but need not include the other three, and all URLs in a Sitemap file must be encapsulated within the tag. We recommend using at least the tag and the flag to let the Googlebot know how often it should check your site for updated content. Be sure to change the date, and maybe even the time, specified in the tag any time you actually update your site.

One more caveat is that your URL specifications must be XML-encoded, similarly to the way they're encoded under RSS. What this means is spelled out in detail here (, but essentially, what you're doing is converting a URL like>2 to look like this:>2 (Note the substitution for the HTML entities & and > for the "&" and ">" symbols.)

Done. Now What Do I Do With It?:

You're almost home. Upload the Sitemap file you create to your server and then add the URL to the file itself using your Google Sitemaps account. You don't need to use the account, but doing so will allow you to keep track of what you've uploaded.

You're welcome to compress your Sitemap file using gzip, found typically on Mac OS X, Linux and BSD (normal PC zipping won't work, although you can certainly find a third-party gzip program for your Windows box). Click the "Add Your First Sitemap" link on the main Sitemaps page after you've logged into your Google Sitemaps account, and that's all there is to it!

You can use your Sitemaps account to keep track of and receive diagnostic information about your Sitemap submissions. You don't need to create a Sitemaps account, however, and if you already have a Google account for receiving Alerts, for accessing the Web Developer APIs and so on, your existing account will work as a Sitemaps account automatically.

Google has already played a significant role in shifting the paradigm of discovering the Web from doing so by following links to doing so by searching, and the company shows no signs of slowing down. Subscribing may well be the next paradigm, based on the flexibility of the protocols that put content syndication in the hands of mere mortals, and getting your content cataloged in these formats should be among your first priorities. The web browser and operating system is adjusting quickly to this new paradigm, and you should be too.
