If you update your website or blog, you might want to say hello to Google. You want to let her send out a bot to check out your updates, and hopefully, index them in good time!

You can do this: Put this URL in your browser - OF COURSE, REPLACE YOURSITEMAP with your actual sitemap!

If you are using blogging software, consider an automatic sitemap plugin that will rebuild and ping every time you update.
