2 min readAn original planning guide. Use the linked primary documentation for platform details and the supported procedure for your environment.
Inventory browser integrations
List analytics, chat, media embeds, advertising, forms, and other external scripts that actually load on representative pages.
Name purpose and owner
Record why each integration is present, which pages require it, and who can approve changes. Mark unknown scripts for investigation.
Measure observed work
Use browser tools to inspect requests and execution around load and interaction. Separate transfer cost from main-thread processing and layout effects.
Test a scoped alternative
Evaluate supported delayed loading, narrower placement, or removal in a controlled environment. Verify required functionality and data handling afterward.
Worked scenario
See the plan in practice.
A support widget loads on every article although the team only uses it on account pages. Review purpose and measured impact before changing placement.
