A meta description tag is the text that you enter in the coding of your pages to reflect the content of the webpage. Google doesn’t count your description as having much SEO value but it helps users to determine whether your site is worthwhile visiting. Therefore it still is very important for attracting traffic and generating sales leads.
This is what your meat description tag should look like in the coding of your webpage: <META NAME="Description" CONTENT="Your text should go here - No more than 153 characters.">
Your description meta tag should be no longer than 153 characters of text. It should accurately sum up the page content. The tag appears in search engines under the title of your webpage. I will give an example below if how a meta description can appear to a user in a search engine below.
There are lots of theories into whether or not search engines pay any attention to meta description tags. We recommend having well constructed meta description tags for two reasons:
1. If you leave the meta description tag empty, search engines will use the text on your page as a replacement. This is chosen at random and might be misleading for the user. For example, it might be the copyright text at the footer of your page.
2. It helps potential visitors to your website to determine whether your website is relevant to your search. This helps the overall process of attracting sales leads and conversions on your website.
