Help extend your Tumblr blog's reach by submitting a site map of the blog to Google's Webmaster Tools. With the site map in hand, Google can more easily find your blog posts, making it more likely they'll get indexed and appear in search results. You can also use the free Webmaster Tools site to track the performance of blog posts in search results. Before your can submit a site map or use the other features, however, you must prove you own your blog by adding a Google verification code to your blog's theme.

Step 1

Navigate to the Google Webmaster Tools website (link in Resources) and sign in to your Google account. If you already use Webmaster Tools for another website, click the "Add a Site" button.

Step 2

Enter your Tumblr URL into the blank field. Use the format "blogname.tumblr.com" (without the quotes here and in subsequent commands). Click "Add a Site" or "Continue" to submit the URL to Webmaster Tools.

Step 3

Highlight the entire meta tag displayed on the next screen and then copy it to your clipboard. This tag contains a unique Google verification code.

Step 4

Open a new browser tab and go to your Tumblr dashboard. Click the "Customize" tab, and then click "Edit HTML" to access your Tumblr theme code.

Step 5

Find the "<head>" tag near the top of the code. Paste the verification tag from Google into a blank line just below the "<head>" tag. Click "Update Preview" and then "Save."

Step 6

Return to the Webmaster Tools page and click the red "Verify" button. Google congratulates you for adding the tag successfully. Click "Continue" to access the Webmaster Tools dashboard.

Step 7

Click the "Sitemaps" tab, and then click the "Add/Test Sitemap" button. Submitting your site map files makes it easier for Google to crawl your blog. Tumblr creates these files automatically; you just need to enter the filenames.

Step 8

Type "sitemap1.xml" into the field that appears, and then click "Submit Sitemap." This file includes a list of all your blog posts.

Step 9

Refresh the page, and then click the "Add/Test Sitemap" button again. This time, enter "sitemap-pages.xml" into the field. This second file contains a list of any custom pages you made, such as your About page.

Step 10

Click "Submit Sitemap" again.
