The challenge

Demand-side SEO existed; supply-side was invisible. Sellers found the platform through outbound, not search.

What we did

  • Seller-intent keyword clusters and comparison hubs
  • Programmatic category pages with entity markup
  • Citation pages optimized for AI marketplace answers
Supply finally compounds the way demand already did.

Starting point

The marketplace had strong buyer-side SEO but sellers arrived through sales outreach. Supply growth stalled because vendor-intent queries were owned by competitors and directories.

Execution

We mapped seller-intent clusters — "how to sell on…", category comparisons, fee calculators — and built hubs with entity markup so both Google and AI engines could cite the marketplace as the authoritative answer.

Results after 8 months

  • ×2.4 seller signups from organic
  • +89% non-branded traffic
  • Top 5 on 19 strategic vendor queries

Takeaway

Two-sided marketplaces need two-sided SEO. Once supply content ranks, network effects accelerate without proportional ad spend.
