Add meta description to a page
The site and page descriptions, also called Meta description, will appear in the search results under the page url. Meta descriptions can be any length, but search engines generally will cut snippets longer than 160 characters. The description has no effect on the page ranking but can draw attention to your site in the search results. Make sure to write a clear, readable & compelling description to encourage the visitors to click on your site.
In order to edit the page meta description click on Edit this page and on Settings. In the field Meta description, write the description of the page.
