The main purpose of a meta description is to get people to click on your link and visit your webpage.
While meta descriptions used to be used by Google as a ranking factor, they are no longer a ranking factor for Google. For this reason, many people don’t enter a meta description for their pages.
However, meta descriptions play an important and indirect role in boosting your site’s SEO! Writing meta descriptions is not a step you should skip, as Google considers the click-through rate (CTR) of your pages as one of its ranking factors.
