To make a project visible to search engine crawlers, enable Search engine optimization in the Privacy tab in your project settings. After the project is published, search engines will start indexing your project automatically.
Note: in order to prevent spam projects, search engine indexing won’t be available on Free plans beginning July 10, 2019.
In the General tab, you can specify the title, description, and keywords for your project. If you are using a custom domain, make sure to enable SSL and, if needed, upload a favicon—this can be done in the Domain tab of your project settings only after the domain is successfully mapped.
Additionally, if your plan includes Sharing Settings (available with Professional and Custom plans), you can customize the title, description, and cover for each page. To do this, open your project in the page overview mode, click the wheel icon on the cover of the desired page, and go to the Sharing tab.
On all plans, you can also set up a URL for each page to display instead of its number: e.g., the link domain.com/1/ will be changed to domain.com/portfolio/. To do so, click Custom URL next to a page in the page overview mode and enter a new title.
To set <h1>, <h2>, <h3>, or <h4> tags, use Styles attributes in the text widget. You can find more information here: Text.
Note: if the metadata for your project is not shown correctly on Google, you can force reindexing using the URL Inspection Tool from Google Search Console.
