The following are the top four best practices for SharePoint 2019
- Plan the information architecture: In SharePoint 2019, every site is a site collection and can be associated with a hub. A hub is a flat collection of sites which share navigation, branding, and other elements.
- Personalize the page banner: Use good text descriptions and use quick links for the most relevant material. Show long text in the form of collapsible sections.
- Evaluate site performance: Use the site performance feature to evaluate the performance of a SharePoint site.
- Keep the content up-to-date: Ensure that the content is up-to-date and relevant to the intended audience.
