Ad-blocking preflight checklist

1. Confirm the destination

• Use HTTPS and verify the final public URL.
• Remove unnecessary redirect hops and URL shorteners.
• Check the response on mobile and without an existing session.
• Make sure navigation and conversion still work when analytics fail.

2. Inspect delivery names

Review hostnames, script paths, iframe sources, element IDs, and CSS classes. Terms such asads, banner, sponsor, pixel, and trackingmay deserve filter-list verification, but a token match alone is not proof of blocking.

3. Reduce tracking dependencies

• Remove duplicate analytics and conversion tags.
• Keep optional measurement separate from essential page behavior.
• Document which vendor owns each third-party request.
• Test consent and privacy settings before adding campaign traffic.

4. Prepare the creative

• Make the product and offer understandable without surrounding page copy.
• Use a specific call to action that matches the landing page.
• Export platform-appropriate sizes instead of relying on automatic cropping.
• Check small-screen legibility and file weight.

5. Save evidence

Record the browser version, blocker profile, rule-list version, time, region, network trace, and screenshots. Without those details, two teams may be discussing different test environments.
