Still a SEO newbie.
When comes to the time need to submit sitemap to Google Web master tool, hit errors:
1. I submitted a html site map provided by marketing team. Google seems doesn’t like it.
2. Second submit was a xml file provided by marketing team as well. XML syntax not right.

Found this free xml sitemaps tool. Few simple steps and you will be able to generate a Google happy sitemap.
