Blogspot seo How to submit a XML sitemap

In Google Webmaster Tools in the submit Sitemap where after your blog name you see the  "My Sitemap url is" blank, type this:

Steps of 100
atom.xml?redirect=false&start-index=1&max-results=100 (If you have up to 100 posts)
And if you have more than 100 articles or posts, then you have to add more sitemaps, after you have already added the previous one, like these:
atom.xml?redirect=false&start-index=101&max-results=100 (If you have up to 200 posts)
atom.xml?redirect=false&start-index=201&max-results=100 (If you have up to 300 posts)
atom.xml?redirect=false&start-index=301&max-results=100 (If you have up to 400 posts).

or you can try this with steps of 500

atom.xml?redirect=false&start-index=1&max-results=500
next sitemap:
atom.xml?redirect=false&start-index=501&max-results=500
and similarly next:
atom.xml?redirect=false&start-index=1001&max-results=500

Bei Problems Change atom.xml with rss.xml (keep rest of the link-tag same)
i.e.
rss.xml?redirect=false&start-index=1&max-results=100
If again error is detected, then instead of starting from 1, do it from 10, like this:
atom.xml?redirect=false&start-index=10&max-results=100
