See the page the way the ad tags do
Ad Fixer inspects how your page renders and maps where each ad placement sits. It helps you catch layout and placement issues before ad tags ship, so units render in the right place at the right size.

How it fits the platform
Ad Fixer complements the free site diagnostic: run the diagnostic to find issues, then use Ad Fixer to verify page render and the placement map before you ship changes. Start at https://sulvo.com.
