Sitemaps, in simple English, are text files (see Sitemap) containing a list of all web pages that exist on your site. It is important that you create a comprehensive sitemap as it will help Google and other search engines crawl your site better and that might mean more traffic coming your way in the long run.

The Problem with Blogger Sitemap Files

Ideally, the sitemap file should contain all URLs of a site but if your blog is hosted on blogspot.com (or if you are using a self-hosted version of Blogger with a custom domain), you'll be surprised to know that the default sitemap file (see example Sitemap) contains only the 26 most recent pages of your blog.
That's a bad thing because some of your older blog pages, that are missing from the system-generated sitemap file, may never get indexed in search engines. There's however a simple solution to fix this problem.

Generate a Complete Sitemap for your Blogger Blog

Step 1: If you haven't done this already, sign-in to your Google Webmasters account and add your blog. For details, check this video tutorial on how to add a blog to Google.

Step 2: Once your blog is added to Google, open the Sitemap Generator and type the full address of your blogspot blog (or your self-hosted Blogger blog).



Step 3: What you get is list of sitemap files that contain each and every page of your blog. You now just have to ping Google, Yahoo and Bing to inform them about these XML sitemaps.
As shown in the video screencast below, you need to manually add each of the sitemap files into your Google Webmaster Tools dashboard but for Bing or Yahoo, you can simply click blue hyperlinks and these search engines will automatically download the relevant sitemap files from your blogspot site.





Once all the Sitemaps are added, your Google Dashboard should look something like this.
