Though web browsers are becoming more and more advanced, that doesn’t mean you should build websites that you know only the latest web browsers support, nor should you build websites that GoogleBot, Google’s web crawler, cannot fully crawl and index. That was the advice from Google’s John Mueller, when asked about Google’s status on modernizing GoogleBot to a more recent version of Chrome.
Mueller said it is of his opinion you should make your web pages “work with the status quo” of how GoogleBot currently crawls the web. He said it is best to do that than “rather than waiting for bigger changes, if you care for search.
Google is an essential traffic source for many and we need to make sure we aren’t building sites that’re so advanced that the current Googlebot can’t index them correctly. With Google it’s best to stick to the status quo.
