Thanks Alan,
I will continue to use the server response setting when generating other sitemaps and recommend that our Techs ditch the home grown script that assigns the single date and time in future.
II must say also, it is great to have such clear and reliable advice - very glad to have you around!
Thanks again.
My Tech lead is concerned that his use of a script to generate XML sitemaps for some client sites may be causing negative issues for those sites.
His concern centers around the fact that the script generates a sitemap which indicates that every URL page in the site was last modified at the exact same date and time. I have never heard anything to indicate that this might be a problem, but I do know that the sitemaps I generate for other client sites can choose server response or not.
What is the best way to generate the sitemap? Last mod from actual time modified, or all set at one date and time?
