The purpose of meta descriptions has always been to help people decide which search results are the most useful for answering their queries. Google
claims that the point of longer, more descriptive snippets is to improve user experience. There are mixed opinions about the actions to take next, considering this is still a recent development. Most web gurus are arguing that changing every snippet to be optimized for the longer limit is a waste of time. For example, the SEO experts at Search Engine Land assert that the Google is moving towards dynamically generating snippets based on a user’s query and content found in both the meta description and the content visible on the page
. It would probably be in your website’s best interest to re-optimize the meta descriptions of only your most important, high-performing web pages for this new 320-character maximum length. In the words of Matt Southern from Search Engine Journal
, “…expanding all meta descriptions would be wasted effort, so continue to focus on more important tasks.” However, keep in mind if you have a WordPress website that the SEO firm Yoast updated the recommended meta description length on the Yoast plugin to match Google’s recent change.
