Avoid Ranking Downturns: Do this before you revamp your website
If your business runs a website that has ranked highly in search engines' results pages because it has successfully been in operation for some time with the proper search engine optimization, you need to be careful with how you redesign your website. Search engines rely on the URLs of a website's pages remaining consistent even as the website undergoes a redesign in order for those engines' promotion algorithms to keep considering that website promoted in terms of how high in search results it will appear as. If a search engine's web crawlers attempt to make one of their routine and automated check-ups of a given page's contents but do not find anything at the exact URL that page used to be located at, the engine will proceed as though the content is no longer on the Internet and will dock the website's rankings accordingly. What the search crawlers come across when a recorded URL has been changed is analogous to the 404 error message screen that any typical user of the Internet will be faced with if a URL address is typed in but nothing exists at that specific URL anymore. A website owner who is aware of this potential pitfall but nonetheless needs to restructure their website in terms of the URLs each of its pages is occupying needs to immediately implement commands that redirect outside entities toward the new URLs that are now hosting previous content. These are called 301 Redirects, and they indicate that the web page or the website itself has "moved permanently" to the location being pointed to. Search engines will parse the contents of the redirects and therefore assume that the pages being pointed to reflect what the previously recorded website's current rankings should now be driven by. Proper implementation of 301 Redirects should minimize the ranking downturn that typically occurs when a website changes either some or all of its URLs. If a redesigned site has lost some of its standing with search engines, however, it will have to reuse previously successful SEO techniques to gradually earn that back.
