The Problem

Google Crawls Your Filters While New Listings Wait Weeks to Be Found

It shows up when Search Console reports far more discovered URLs than you have listings, most of them filters and expired items, while sellers say their new listings don't appear in Google.

  1. Filters

    Filter combinations fill the crawl with near-duplicate pages.

    Filters

    Only filters with real search demand get indexable pages.

  2. Expired listings

    Sold listings return empty pages or soft 404 errors.

    Expired listings

    Each listing state has a rule for its status code and similar items.

  3. Duplicates

    Several sellers post the same product with copied descriptions.

    Duplicates

    Duplicate offers merge into one product page with every seller listed.

  4. Empty pages

    Category pages for small towns show zero results.

    Empty pages

    Category and location pages publish only where inventory exists.

Search Console lists far more URLs than you have listings. Most are color, size, and price filter combinations, plus listings that sold months ago and now show an empty page. Several sellers list the same blender with the same copied manufacturer description. Category pages for small towns show zero results. New listings take weeks to appear in Google, so sellers blame your marketplace and post their stock somewhere else.

We start with crawl rules: which filter combinations deserve indexable pages and which stay out of the crawl, following Google's faceted navigation guidance. Sold and expired listings get a clear rule. Seller duplicates point to one product page with every offer. Category and location pages go live only where inventory exists. Our developers make the changes in your codebase, so Google spends its time on listings that can sell.

  • Crawl rules for filters

    Which filter combinations get indexable pages and which stay out of the crawl, set per category.

  • Sold and expired listings

    A rule for each listing state: sold, expired, out of stock, or removed by the seller.

  • Seller duplicates merged

    Identical products from several sellers point to one product page that shows every offer.

Our Marketplace SEO Process

From Crawl Audit to Indexed Listings in Five Clear Steps

Your product and engineering leads approve each crawl rule, your marketplace team approves seller guidelines, and each month you see indexed listings and orders or bookings by page type.

  1. We crawl a sample of your marketplace and read Search Console's indexing reports and, where available, your server logs. You get a short report on wasted crawl, duplicate listings, expired pages, and empty categories.

Projects We've Built

Marketplaces and booking platforms from our team, with listing pages, seller and host dashboards, and search filters. None is presented as an SEO result.

What's Included

What You Get With SEO for Marketplaces

A monthly program for marketplace websites: crawl rules for filters, listing lifecycle rules, duplicate handling, category and seller pages, and developer fixes in your codebase. Results are measured in indexed listings and orders.

  • Faceted navigation rules

    Indexable filter pages chosen by search demand, with the rest kept out of the crawl through robots.txt or canonicals.

  • Listing lifecycle rules

    Status codes, sold notices, and similar-item links for sold, expired, out-of-stock, and removed listings.

  • Duplicate listing handling

    One product page with offers from every seller, instead of copies competing with each other in search.

  • Seller profile pages

    Seller pages indexed once they have enough listings and reviews to help searchers, and kept out until then.

  • Category and location pages

    Pages built from live inventory and published only when they have listings to show.

  • Developer-made fixes

    Robots.txt, canonicals, markup, and sitemaps changed by our developers in Sharetribe, CS-Cart, Magento, WooCommerce, or custom code.

What Our Clients Say

What Clients Say After Launch

Feedback from teams we have built and launched websites for.

We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture

Why Marketplace Teams Trust Us With Their Search

Search work for a marketplace lives in the code, the crawl, and the seller experience at once. These habits keep every change safe to ship and every result measured in listings that sell.

  • Developers make the fixes

    Our developers change robots rules, canonicals, and templates in your codebase and send them through your review process. Recommendations that sit in a backlog don't change rankings.

  • Test on a sample first

    New crawl rules go live on one category before the whole site. Search Console data from that sample shows whether a rule helps before we roll it out.

  • Sellers kept in mind

    Listing guidelines help sellers write unique titles and descriptions without slowing them down. A rule that frustrates sellers costs you supply and fresh listings.

  • No bulk thin pages

    We don't mass-produce empty location or category pages to chase keywords. Google's spam policies target scaled pages with little value, and marketplaces are exposed.

  • Measured in orders

    Reports track indexed listings and the orders or bookings they bring, not just traffic. You see which page types earn the crawl they get.

  • Your code, your accounts

    Every change lives in your repository, and Search Console stays under your company's login. If you stop working with us, nothing needs to be undone.

Good fit

  • Product marketplaces with many sellers

    Your marketplace lists products from many sellers, and you need SEO for marketplace sites that stops filter URLs and duplicates from eating the crawl.

  • Rental and service marketplaces

    Your platform connects renters or customers with local providers, and you want marketplace SEO services that build location pages only where providers exist.

  • Marketplaces after a replatform

    You moved from a custom build to Sharetribe or CS-Cart and lost traffic, and you need a marketplace SEO expert to find what the migration broke.

  • B2B and wholesale marketplaces

    Your buyers search by part number and spec, and you want marketplace SEO optimization services that turn supplier catalogs into findable product pages.

  • Agencies building marketplaces

    Your agency builds marketplace platforms, and you need a marketplace SEO agency to handle crawl and listing rules under your brand.

Not a fit

  • Selling on Amazon or Etsy

    You sell on someone else's marketplace, such as Amazon or Etsy, rather than running one. Listing optimization on those platforms isn't a service we offer.

  • Marketplace not built yet

    You still need the marketplace itself. Our Multivendor Marketplace Development service builds it with search rules in place from the start.

  • Single-brand online store

    You run one store selling your own products. Our Ecommerce SEO Services page fits a single-seller store better.

  • Budget under $900 a month

    Your catalog is small enough for a one-time cleanup. Our Technical SEO Services page offers one-time fixes, and we'll tell you before we quote if that's enough.

FAQ

Frequently Asked Questions

Straight answers on marketplace search: what it is, cost, timing, filters, expired listings, duplicates, audits, and ownership.

  • Marketplace SEO is search work for websites where many sellers list products or services, such as multi-vendor stores, rental platforms, and service directories. It focuses on crawl control, listing and category pages, seller pages, and duplicate offers. Most of the work happens in templates and code, not on single pages.

  • A marketplace has far more URLs it doesn't write itself: listings from many sellers, filters, seller profiles, and listings that expire daily. A single store writes its own product pages. Marketplaces need rules that work at scale, plus guidelines that help sellers write listings worth indexing.

  • Our plans start at $900 per month for crawl rules, listing lifecycle fixes, and developer changes on one marketplace. Inventory Pages at $1,450 per month adds category, location, and seller pages plus duplicate merging. Scale Program at $2,300 per month adds monthly log analysis, hreflang, and pages that recruit new sellers.

  • Developer fixes ship within 4 to 6 weeks of the audit, and crawl stats in Search Console usually shift within a few weeks after that. Indexed listings and organic orders build over 3 to 6 months. Large marketplaces often see crawl changes first, because Google revisits their busiest sections often.

  • Give indexable pages only to filter combinations with real search demand, such as category plus brand or category plus city. Keep the rest out of the crawl with robots.txt rules, as Google's faceted navigation guidance recommends, and return a 404 for combinations with no results. Keep filter order and URL separators consistent.

  • It depends on whether the item can return. A listing that is out of stock or likely to be relisted stays live with its availability marked. A one-off item that sold can keep its page with a sold notice and similar listings, or return a 404 or 410 once it has no value. We set one rule per listing type.

  • Point every seller's offer to one product page that lists all the offers, instead of letting copies compete. Product markup on that page can describe offers from several sellers. Listing guidelines then help sellers add their own details, such as condition or bundle contents, without creating a new page.

  • They cover crawl waste, indexing gaps, duplicate listings, expired pages, empty categories, and links between categories, listings, and sellers. Where you share server logs, the audit shows which URLs Googlebot actually spends its time on. You get a ranked list of fixes with the developer effort for each.

  • Index seller pages once they have enough active listings and reviews to help a searcher. New or empty seller pages add little and can look like thin content, so they stay out of search until they qualify. The threshold is set per marketplace and applied automatically in the template.

  • You do. Every change lives in your repository and goes through your review process, and Search Console, analytics, and sitemaps stay under your company's accounts. If you leave, you keep the written crawl and listing rules and the audit history, so your developers can maintain them without us.
