What is Meta Description?
A meta description is an HTML tag used to describe the content of a web page. This description will show up below the title and URL of your page as it appears in the search engine results. In order to remain visible within Google, it should be kept somewhere between 140-160 characters.
Since meta descriptions appear with your title and URL on the results pages, they have the power to help or hurt your results’ click through rates. Research has shown that having the keyword in the body of the meta description is a relevancy signal for search engines that can help your rankings.
It isn’t a huge signal, but it can certainly play a positive role if used naturally without keyword stuffing your descriptions. In terms of your search result, your meta description has the most real estate (two lines of text compared to one line for the title and one line for URL), so take advantage of the opportunity to sell your website with a meaningful message to searchers.
