A meta description is a short summary of a web page's content. It is displayed in the search engine results pages (SERPs) under the page's title and URL. Meta descriptions are meant to give users a brief preview of what a page is about, so they can decide whether or not to click through to it.
While meta descriptions don't directly affect a web page's ranking in the SERPs, they are important for driving traffic to your site. A well-written meta description can make the difference between a user clicking through to your site, or moving on to another result. This makes them an essential part of any SEO strategy.
To write a good meta description, keep it under 155 characters and focus on creating an enticing preview of your page's content that will encourage users to click through. Make sure to include relevant keywords for your target audience, as this can help improve your click-through rate.
