Publisher: +€62K/mo revenue and 178% more AI citations

Starting point

850K sessions per month sounds healthy — until RPM keeps dropping and newsletter growth stalls. The publisher had traffic without monetization: ad rates under pressure, sponsors asking for proof of audience quality, and organic flat on high-intent topics.

Strategy

We treated the site as a semantic graph, not a pile of articles:

1. 47 new hub clusters — Expanding coverage on topics where RPM and sponsor interest were highest.
2. Schema + entity markup — Making content machine-readable for search and AI engines.
3. GEO citation optimization — Pages structured to be referenced in AI Overviews and answer engines.

Results after 11 months

• +€62K/month incremental ad and sponsor revenue
• +41% newsletter signups from organic landing pages
• +178% tracked AI citation mentions

Takeaway

For publishers, GEO is the new front page. Traffic that doesn't get cited in AI answers is increasingly invisible to the next generation of searchers. Semantic depth + entity markup turned existing authority into revenue — without doubling content production.
