When you redesign your website, often you will add, rename and remove some pages as part of the restructuring that inevitably happens at the same time.

You should take care to remove your old website before uploading your new website; this will ensure any old pages aren’t left lying around for visitors to stumble upon and become lost.

Then, make sure your web developer puts in place a “redirect” for every old page to an equivalent new page (or the home page, if there isn’t a good match.) Not only will this benefit visitors who might have bookmarked a certain page, or clicked a link from another person’s website; but the search engines will use this information to update its index and make sure it displays your new pages rather than your old pages in the search results.
