Recent changes made to your website may not be displayed in Google search results because it takes some time for Google to re-crawl and re-index your site.

- under PAGES, hover over the page whose Description you would like to change and click the Settings icon that appears to the right of it:
- under PAGE SETTINGS, type the page description into the DESCRIPTION field to suggest content to appear in search results:
