If you would like to change the keywords or description of your page, and therefore how your page is displayed on Google, that can be done via the website editor.
Begin by logging into the website editor via the Intranet:
From there click on "Content":
Select the page you wish to edit (usually the home page is best used for keywords and descriptions):
Then scroll to the bottom and click on "Edit Select Page". At the next page scroll to the bottom and select "My Fields" then enter the title, description, and keywords you want. Make sure to separate each keyword with commas:
Finally click "Save" and you're done!
Please note: It can take a while before Google will pickup changes to your title, description, and keywords, so you may not see it change for several days in Google.
