Marketplaces reward sellers who treat them as their own discipline.

Amazon and eBay put millions of ready-to-buy shoppers in front of you, but success takes more than listing your products. We create and manage marketplace advertising that helps you stand out in crowded categories, optimise your listings and win more sales.

Marketplaces are search engines as much as shops, with their own algorithms and ad formats. We combine paid campaigns with listing and marketplace SEO so your products rank, convert and stay profitable, not just visible.

Five things that separate marketplace winners from the rest.

Marketplaces are search engines with their own rules. Retail media is booming, the buy box rewards the whole listing, and Amazon needs its own strategy.

01

Marketplaces are search engines too

Shoppers search within Amazon and eBay. Listing SEO decides whether your products appear, before any ad spend.

02

Retail media is the fastest-growing ad channel

Sponsored placements on marketplaces are growing fast. Brands that master them reach buyers at the moment of intent.

03

The buy box rewards the whole listing

Price, reviews, images, stock and content all feed visibility and conversion. Ads alone do not win it.

04

Amazon needs its own strategy

Copying a Google Ads playbook onto Amazon underperforms. The platform, formats and metrics are different and demand their own approach.

05

Data closes the loop

Sales, click-through and conversion data per ASIN and listing are what turn a marketplace presence into a profitable one.

Our marketplace and retail media services, end to end.

From Amazon and eBay advertising to listing optimisation, marketplace SEO and the analytics that keep your campaigns profitable.

What brands ask before they start.

What is marketplace advertising?

Promotional strategies sellers use to promote products within online marketplaces like Amazon and eBay. It includes formats such as sponsored products, display ads and video ads that increase visibility and drive sales, targeting keywords, demographics or shopping behaviour.

What are marketplace optimisation techniques?

Strategies to improve ad performance on platforms like Amazon and eBay: keyword research to find high-traffic terms, refined targeting, regular bid monitoring to control costs, and analysing click-through and conversion rates to keep improving.

How can I advertise on digital marketplaces?

Create a seller account, choose your ad formats, research relevant keywords, set your budget and bids, then create compelling ad copy and visuals and monitor performance. It is a lot of work, and each platform differs, which is exactly where we help.

Is it free to advertise on marketplaces?

Generally no. Most platforms use a pay-per-click model or charge for ad placements, with costs based on clicks, impressions or fixed fees. Some organic reach is possible, but paid options are usually needed to drive visibility and sales effectively.

Can I advertise on Facebook Marketplace?

Yes. While Facebook Marketplace focuses on peer-to-peer selling, businesses can list products and use Facebook Ads to promote those listings to targeted audiences, increasing visibility and driving sales.

Do you handle both ads and listing content?

Yes. We manage advertising and the listing content and marketplace SEO together, because on marketplaces the two are inseparable, your ads only convert as well as the listing behind them.
