By default, the website will be accessible to search engines but for you to configure how it will appear on Google results, you have to configure this in the SEO section of every page and the overall SEO settings.

To get started to configure the SEO of every page (and how it will appear on Google results & & Social Media preview) go to the Pages section (in the admin area).

Then click on edit. (Not HostFiti Builder).

Then scroll down to the section labelled SEO.
