When the home page is set to be a page, not a post or series of posts, the sitemap date entry for the home page doesn't change when the page has changed. So even though I've changed SEO configurations and the text etc in the chosen page, the sitemap entry for the homepage is stuck at seven days ago. I think this is why Google is not updating, despite the fact the googlebot is doing its thing and the plugin is notifying google. If it's told the index page hasn't changed in a week, it doesn't bother updating, why should it?
I'd rather not move things around to fake it, but what can I do to jig the revised date of the homepage in the sitemap?
Thanks for your time
