Hi:
I have installed the XML Sitemap Generator from this link
http://wordpress.org/extend/plugins/google-sitemap-generator/
I submitted the sitemap to Google using Google webmaster tools. It took one day to get most of my pages indexed by Google. After that I made a change to the plugin, to have some pages crawled every week instead of monthly.
My question is:
Do I have to resubmit the sitemap to Google again?
Or is the sitemap dynamic, and Google will be informed of the recent change to crawl the pages weekly instead of monthly?
