Submit a sitemap to Google Webmaster Tools

Creating a sitemap helps search engines better crawl and categorize your site. You can easily create and verify a sitemap for any of your publicly viewable Google Sites through Google Webmaster Tools.

1. Verifying your site with Google Webmaster Tools

Before Google Sites will generate a sitemap, you must verify your site with Google Webmaster Tools:

1. Sign in to Google Webmaster Tools using the same account information you use to sign in to Google Sites.
2. Click "Add a site...", enter the base URL of your Google Site in the box that pops up, then click "Continue."
3. On the following page, select the radio button next to Add a meta tag to your site's home page.
4. Copy the meta tag (for example, <meta name="google-site-verification" content="z5mJLjVGtEe5qzCefW1pamxI7H46u19n4XnxEzgl1AU" />) from the Instructions box.
5. In a new browser window or tab, navigate to the Google Site you wish to verify. (You will need to go back to the Webmaster Tools page, so do not close it.)
6. Select Manage site from the "More actions" drop-down menu.
7. Select the General tab under the Site Setting area.
8. Paste the meta tag that you copied on the Google Webmasters Tools site in the box next to Google Webmaster Tools verification.
9. Click "Save changes."
10. Go back to the Webmaster Tools page where you copied the meta tag.
11. Click "Verify."

2. Submitting your Google Site's sitemap to Google Webmaster Tools

1. On your Webmaster Tools home page, select your site.
2. In the left sidebar, click Site configuration and then Sitemaps.
3. Click the Add/Test Sitemap button in the top right.
4. Enter /system/feeds/sitemap into the text box that appears.
5. Click Submit Sitemap.

3. Locating your sitemap for later use

You can navigate to your sitemap by adding /system/feeds/sitemap to the end of the base URL of your Google Site.
