Working with data sources and media

• Clean up unused data sources
• Do not put media items directly under the site’s Media folder and instead use the general Media Libary folder (sitecore/Media Library).
• Give site data sources meaningful names and organize site data sources in folders
• Run source field reports to help set the data source context. The Source field specifies where the user is allowed to look for the data source.

Extending SXA

• Never put custom items in SXA-controlled branches of the tree. Place custom modules in a branch that is a sibling to the Headless Experience Accelerator module root.
• Do not modify OOTB SXA items
• Create an SXA module for your custom renderings
  • Provide site/site collection scaffolding integration for your modules.
  • Include data source definitions for your components (or re-use OOTB SXA data sources).
  • Define site-relative queries for your data sources.

Base your custom templates for pages on the Page template

When you create a custom template that represents a page, you must select the Page template as your base template. Otherwise, certain functionality might not work.

Consider using existing renderings before building a new one

Limit scope of fields linking to items with queries

Sharing content

• Consider defining your rendering variants, page designs and partial designs in the shared site
• Consider creating a master site to clone for a rollout to new markets
• Consider using delegated areas for pages that share content across sites
• 
• Consider using a shared site as the exclusive style container in a site collection to avoid duplicated styles and redundancy.

Structuring pages

• Set placeholder restrictions
• Use site-specific page branches instead of standard values to set modifiable presentation details for your pages
• Use partial design inheritance
• Prioritize changing the grid settings of a rendering over using splitters to change the layout of a rendering

Enhancing SXA performance

• Limit the number of renderings on a page(<30)

Using renderings

• Use the proper rendering for the job. Avoid using versatile renderings such as Page Content, Page List, Promo, or Rich Text to render most of your page layout. 
• Make sure the Rich Text field content is fully editable

Hope this helps, Good luck!
