Google SiteMaps - Get ALL your pages listed!
by Robert Fuess


Google has a new trick! Don't get left behind! It's the hottest thing since RSS.

I was working on my Google AdWords campaign for SchoolAndTeacher.com and I noticed that Google had a new feature called "Google Sitemap". It was a perfect fit with my needs. I was concerned with how deep Google would be able to get into my site. Teachers are able to have homework posted daily on my site but will Google see the daily changes? Now they can. When a new teacher signs up, how many months will it be before Google recognizes it? With Google Sitemap, Google can be informed about new pages quickly and when a page last changed.

If you have a website and want Google to know about ALL the pages in your site, build a Google Sitemap. That's it. Keep reading, since I will show you how to do so, and where it proves most useful.

Webmasters (like me) have been frustrated by the slow methodological way in which Google gradually finds the pages in your site. If your site starts out big and has a lot of dynamic pages, then this is unacceptable. Hurray for Google! They are listening.

Many webmasters like using DHTML menus, but are concerned about the search engines finding all the pages. This will help Google to find them. (In reality, I would still recommend having a regular site-map to help the other search engines find the rest of your pages. Google may drive the most traffic but customers coming in through any search engine are welcome. Don't throw this away.)

DO WE KEEP OUR OLD SITE MAPS?

Yes! The Google Sitemap is not useful to your normal human user just to Google. (It is in XML format, not HTML.) Also remember that other search engines (like Yahoo and MSN) don't use this type of site map yet. Hopefully they will.

WHAT DOES A GOOGLE SITEMAP LOOK LIKE?

It is XML. For XML gurus, here is the schema: http://www.google.com/schemas/sitemap/0.84/sitemap.xsd.

But if you are new to XML, here is a sample. I will go through it. Don't let the tags scare you.

<?xml version="1.0" encoding="UTF-8" ? >
<urlset xmlns ="http://www.google.com/schemas/sitemap/0.84" xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation ="http://www.google.com/schemas/sitemap/0.84 http://www.google.com/schemas/sitemap/0.84/sitemap.xsd">

<url>
<loc>http://www.SchoolAndTeacher.com/OneClass.aspx?ClassId=1</loc>

<lastmod>2005-7-4</lastmod>

<changefreq>monthly</changefreq>

<priority>0.7</priority>

</url>

<url>

<loc>http://www.SchoolAndTeacher.com/OneClass.aspx?ClassId=2</loc>

<lastmod>2005-7-1</lastmod>

<changefreq>monthly</changefreq>

<priority>0.5</priority>

</url>

</urlset>

EXPLANATION OF TAGS:

<?xml version="1.0" encoding="UTF-8" ? >

This should be at the top of the document. It states that this is an XML document and what version of XML is being used.

<urlset xmlns="http://www . . . ">

This tag is the wrapper for all the URLS in the sitemap. Just copy it from the full example above. If you are new to XML, don't fret. Just recognize that this is how GOOGLE wants it.

<url> .. </url>

This wraps the set of XML elements (pair of opening and closing XML tags) for each URL you want to tell Google about.

<loc>YourUrl</loc>

Here is where you put the URL to the webpage you want Google to know about. Try to avoid extra spaces.

<lastmod>YYYY-MM-DD</lastmod>

This tells Google when you last modified your web page. This is a really important tag. (You can put the time in also if you feel the need to.)

<priority>#.#</priority>

This tells Google what you feel is the most important to crawl. These are relative numbers from 0.0 1.0, with 1.0 being the most important. The default value is 0.5 (even if you leave the tag out). THIS HAS NO IMPACT ON PAGERANK!!! This is just a relative weight for Google to crawl YOUR site. If you have all of them at .9 it would be no different than all of them being .1

Look at it this way. If Google was super busy one day and had time to crawl only 3 pages in your site, which ones should it crawl? I would want them to crawl the three with the highest priority (to me) that have changed recently.

BUT I DON'T WANT TO USE XML

You can just provide a text document with the list of URL's. This will help Google find your pages, but will not help Google effeciently decide on what to spider. I would strongly encourage you to build an XML version of google sitemap.

BENEFITS OF USING THE XML VERSION:

Google can know what pages have changed and not have to re-crawl those pages that haven't changed.

If you have a lot of pages and Google doesn't have time to crawl all of your pages all right away, it will focus on the ones that changed according to your priority.

Google is your friend.If they want information on how to efficiently crawl your site give it to them.

WHAT TO SUBMIT?

You may submit a sitemap, or an index of your sitemaps. Either will do. Google has documentation on both. (Don't worry about the index yet. That is addressed at the end of this article.)

I BUILT ONE - NOW HOW DO I SUBMIT IT?

First TELL GOOGLE IT EXISTS

Upload your Sitemap to your site to the highest folder in your website.
Sign into Google Sitemaps with your Google Account. (Use this link: Google Sitemap Login )

Click on "Add a Sitemap" link.
Type the URL to your Sitemap location.
Congratulations! Google now knows about it!

Now tell Google whenever something changes. It will check this sitemap to see where the changes are.

Quick and Easy Way:

Type the following into the address section of your browser:

http://www.google.com/webmasters/sitemaps/ping? sitemap=http://www.YourDomain.com/YourSitemap.xml

Of course, you should replace the YourDomain.com with your domain and YourSitemap.xml with your sitemap.

If you have a dynamically built site then you would want to automate this using screen scraping techniques.

HOW OFTEN TO SUBMIT?

Ideally, it should be submitted when changes are made. Personally, I would avoid doing so more than once per day. However, we will look to Google as they may provide further guidance on this. Search engines are our friends, and we should be respectful of abusing any service they provide or making them process things needlessly.

WILL THIS IMPROVE MY GOOGLE RANKING?

Google doesn't make any promises of this. This is mainly a way for Google to find your pages, and to efficiently know what pages need to be re-crawled on your website. If your site makes frequent changes, this feature helps Google to know about them more quickly. It won't have to spider through your whole site to find the changes.

HOW MANY URLs CAN I HAVE IN A GOOGLE SITEMAP?

According to Google documentation, you may have up to 50,000. If you anticipate more than this, then you should build several sitemaps and use a Google Sitemap Index. This Index will point to the several sitemaps. If you want more information on the Sitemap Index, go to
