Sitemap Make sure you have an up to date sitemap.xml or sitemap.html page linked from your home page. This is what the search engines crawl to find your content.
Redirects If you change the URL of a page on your site, don’t leave your users or search engines hanging. Set up a 301 re-direct. This is a file that is put on the server itself and re-directs users to the new URL while also telling search engines that the page has been permanently moved and has to be re-indexed.
