Hi everyone,
There have been some questions lately about using Google Sitemaps for
submitting commercial websites. We will be adding something to our FAQ
soon to address this. In the meantime, the short answer is that YES,
it's okay to submit commercial websites to Google Sitemaps. The
official answer will be:
Can I use Google Sitemaps to submit URLs for commercial websites?
Yes, the Google Sitemaps program would like to know about all the URLs
you would like included in the Google index, including commercial
websites.
Hope this helps!
