"In its simplest terms, a Sitemap is a list of the pages on your website. Creating and submitting a Sitemap helps make sure that Google knows about all the pages on your site, including URLs that may not be discoverable by Google's normal crawling process."My next project is to study their Webmaster Guidelines.
Google site Map Step by Step
First add your site to your Google Webmaster Tools account. Once you've added it, the next page will ask you to get your site verified by Google. To verify, you can either add a meta tag to your web page or upload an html file. If you don't have access to the server, then use the meta tag feature. I used the meta tag feature for my blog.
Once your site is verified, you should have the chance to add the site map. For my GalleryJuana.com website, I created a txt file . Basically, I typed out the urls for my site in notepad and saved it as a .txt file, then uploaded it to my server. Next, in the Google Webmaster tools' dashboard, I clicked on the Sitemaps section and added my sitemap url.
For my blog, it was much easier. In the Google Webmaster tools' dashboard, go to the Sitemaps section and add your RSS/Atom feed url. I entered the RSS feed url for my blog. The Atom/RSS feed url looks like this:
So mine is http://GalleryJuana.blogspot.com/feeds/posts/default
You only need to add what is missing which I think is feeds/posts/default.
Now, you just have to wait for google to update and hopefully show there are no errors.
