The meta description is an HTML tag which tells Google about a product/service. It is a brief snippet of a webpage content which allows users to get an idea about what they are going to find inside. Meta descriptions are useful in getting visitors from search engines to click on a link for a particular web page, thereby generating more clickthroughs.
If the meta tag is not included in the page, Google fetches the content for the meta description automatically from the particular web page to display in search results. The ideal length of a meta description is around 110-150 characters.
Meta Description HTML Tag:
<meta name="description" content="This page will provide the information about your x product"/>
