Marketplace SEO

Marketplace SEO is the practice of optimizing a site based on its inventory (supply) so that potential buyers (demand) land directly on your marketplace when they are about to make a decision, like booking a flight or scheduling an appointment.

Marketplaces are platforms that connect supply and demand, and Kevin calls them “SEO Aggregators.” The work is heavy on the technical and product side because you manage hundreds of thousands, sometimes millions, of programmatically generated pages.

For marketplaces, good SEO is the result of product growth, not just website optimization. Organic search brings the majority of new users, so SEO is the growth engine rather than a side channel, and low per-user revenue often makes paid acquisition too expensive to scale. That pushes the work toward page quality, crawl efficiency, and internal linking across the whole inventory.

Imagine a mid-market marketplace connecting tutors with students. It has 200,000 tutor pages, but only 40,000 are indexed because of thin profiles and wasted crawl budget. Improving profile completeness and internal linking gets 150,000 indexed and lifts organic sessions 60% in 2 quarters, without adding a single editorial article.

Treat marketplace SEO as a product function: Prioritize supply quality and the system that generates pages, not one-off content. Fix the technical foundations that matter at scale, crawl efficiency, internal linking, and page quality. Use user-generated reviews to build trust, relevance, and long-tail keyword coverage. Plan for AI eroding the moat by diversifying page types and defending brand demand.
