Why use Pillar Content Gap Mapper?
SEO and AEO only partially overlap. We found that only 62% of keywords where a domain ranks in Google top 10 are also cited in AI answers. Pillar Content Gap Mapper shows you exactly where the 38% gaps are in your site structure.
The tool is the only one that connects a site crawl with AI citation data per pillar section. You don't just get a list of keywords lacking AI coverage, but a structured overview of which parts of your content architecture need improvement.
Combine with Citation Gap Analyzer for deeper per-keyword analysis, or AI Topic Opportunity Finder to discover specific sub-topics you should cover. Together these tools give you a complete picture of your AI visibility.
