Text can be added in a Text Content Type near the top of a page where it will be out of the way on the Webpage.
It is recommended to Set the text to a small size and blend the color to match the background. This will hide the text from the page and allow the search results to display relevant text. You can do this through the HTML editor or via a Style and apply the Style to that text block. For example if your website background is white, add the Text and style the font to also be white, this way it does not display to users on the site, but will display for Search Results.
