Meta Description

A meta description (sometimes called a meta description attribute or tag) is an HTML element that describes and summarizes the contents of your page for the benefit of users and search engines. 

Meta description tags can have a significant impact on your search engine optimization efforts.

Remember your meta description acts as "organic ad text", so when your ad ranks for a keyword, Google and other search engines will often show the meta description as a summary of the page.

The best practices for creating a good meta description are:

1. Make sure they're hyper-relevant to the content on each page; never use the same meta description across your whole site.

2. Use researched, targeted keywords in your meta descriptions.

SEO Keywords 

Keywords are very important for every website as they drive targeted web traffic to your business for free. To create content that ranks well organically and drives visitors to your site, you need to understand the needs of those visitors - the language they use and the type of content they seek.

Your goal in ranking on search engines is to drive organic traffic to your site from search engine result pages (SERPs).
