Adding sitemap to your blogger or blogspot site

I am checking my blogs and realized that my blogspot sites do not have identified sitemaps. I check the web on how to do it since we all know that we cannot really upload a file in blogspot. Check it out:

go to google sitemap after add your URL blog then verify your blog
it will generate code for you
you have to put in in your blog >>setting >>edit HTML
Put the code below [head] then click verify

After that go to add sitemap

select add general web sitemap

then fill xttp://xxx.blogspot.com/atom.xml YOu have to fill atom.xml
then fill xttp://xxx.blogspot.com/rss.xml YOu have to fill rss.xml
then click submit

* trying gsitecrawler is a good option too
