Step 1: Head over to your blogger account and click Layout.
Step 2: Next, click Add a Gadget.
Step 3: Find the gadget titled Labels. Then click on the arrow. This will add the gadget to your site. You can adjust the placement.
The photo on the left is of the site map on my site with the labels I have chosen to use so far. I have not gone through my entire blog labeling each blog post yet. The photo on the right is of the post settings box that appears as you write and edit your blog posts. This makes labeling much easier because the labels have been saved. Once you click on a saved label it is automatically placed in the box.
Can you think of any other benefits to adding a site map to your blog?
