When adding a new section to the page, always title that new section with a heading. To create a heading, type the title of the new section like you see in the image below, highlight the text and select ‘Heading 2’ from the drop down. This will organize your content and provide a better user experience. Google also scans Headings, so if possible use keywords in your headings.
After adjusting your different levels of Headings, be sure to hit 'Save changes' followed by 'Publish'.
Tip: If a word is identified as misspelled by your Firefox browser, you can switch to Source mode (top left button of your content editor window) to right click on the misspelled word and either add it to your dictionary or select the correct spelling.
