Google stealthily changes a major SEO feature for websites

People have been noticing that their meta descriptions have decreased from 320 characters to about 155 characters. Other facts about meta descriptions appear to be changing as well, without any notification from Google. Two months ago, meta descriptions were 320 characters in length, however, Google has said before that the length is truncated to fit the user's device. Shorter meta descriptions make sense for mobile users. A meta description is a small snippet of information that appears in the SERPs under each link so searchers know what to expect if they click on the link. People want short, concise text when deciding if a website has what they want; 320 characters is not short and concise. If most of your traffic comes from mobile users, make the most of the first 100 or so words in your meta description. Skip your brand or company name; if people were looking for your brand, they would have used your brand name in their search query. It is vital that a meta description accurately describe a page and is not spammy. When Google sees a meta description that is just keywords that are outright spam, the search engine will ignore the meta description altogether. No matter what length meta description Google allows, write the snippet to accurately describe how the page benefits the searcher. People have short attention spans; even if you can get 320 characters to show in the SERPs, people won't read all of the description. They will read enough to know whether your page is what they want. Use a different meta description for each page of your website. Google will always do what it wants. They may show your meta description or they may not. If Google shows your meta description, it will show as many characters as will render well on the user's device. If you have good meta descriptions already, keep them as they are and focus on creating new content.
