What are Conversion Blockers?

Modified on: Thu, 24 Mar, 2022 at 10:40 AM

Conversion blockers are insights found regarding your Google Ads landing pages that can negatively impact paid search performance and ROI.

Landing pages are discovered using the Siteimprove to Google Ads integration. Conversions blockers are then identified using Siteimprove’s crawler technology for each landing page.

The results of these checks are presented on a Page report within Siteimprove Ads along with a business impact description and advice on how to address the issues. 

Note: Siteimprove checks the active landing pages every 5 days.

The following checks are carried out on the landing pages in order to determine any conversion blockers.
