I need a sitemap that I can submit to Google Webmaster tools.
I am talking about a website, which is showing around 39,600,000 results for "site:domain-name.com".
I know that a sitemap can contain multiple sitemaps (lets say 20 or 30 etc). This is probably what I would need to do.
Do you have an idea where would I create something like that, and preferably for free?
