Best Practices for Content Authors

Overview

These practices help you keep Marketplace pages fast for shoppers.

The platform delivers pages quickly at the edge, and content quality controls determine how much data the browser has to download and render.

Images

• Upload images at display dimensions, not camera resolution.
• Provide a dedicated mobile image for hero sections.
• Compress images before uploading.
• Use WebP when your tooling supports it.
• Write descriptive alt text on every image.

Recommended mobile hero image guidance:

• 750 to 900px wide
• Compressed before upload

Video

• Use video only when a still image cannot deliver the same outcome.
• Keep background video files under 3MB.
• Keep loops short.
• Provide a still image fallback for mobile.

Page structure

• Keep sections flat and sequential.
• Avoid nesting sections inside sections.
• Put the most important content first.
• Treat every added section as render work the browser must complete.

Tag management

• Audit GTM regularly and remove stale tags.
• Consolidate analytics tools to reduce duplicate trackers.
• Test tags in preview mode before publishing.
• Avoid tags that inject DOM elements, which can cause layout shift.

Redirect hygiene

• Update internal links to the final destination URLs.
• Remove redirect chains as part of routine site maintenance.
