Product feed

A product feed is a structured data file in which you collect all the product information from your online shop: product name, price, image URL, description, stock status, delivery costs and unique product IDs. You submit this file in a standard format such as XML, CSV or TSV, so that external platforms such as Google Shopping, Meta Shops or marketplaces like Bol.com can automatically display your products. The feed acts as a bridge between your online shop and advertising channels, making your products discoverable to buyers the moment they start searching.

How a product feed works

Your online shop generates the feed automatically via a plugin or export function. The feed contains one line per product, with columns for the mandatory and optional attributes required by the receiving platform. Google Shopping, for example, requires at least id, title, description, link, image_link, price and availability. The feed is hosted at a fixed URL or uploaded periodically. Platforms retrieve the feed daily or hourly, ensuring that price changes and stock updates are immediately visible in your adverts. If there are errors in the feed – such as a missing GTIN or incorrect currency – you’ll receive error messages in Merchant Centre. You must resolve these before your products go live. You can find more information about feed specifications in the Google Merchant Centre Help.

Why product feeds came about and why they matter now

Product feeds came into being when comparison sites and search engines wanted to display product adverts without having to manually crawl every online shop. A standardised file made it possible to import thousands of products in one go and keep them up to date. Today, the product feed forms the backbone of performance marketing for online shops: without a feed, there is no Google Shopping, no dynamic remarketing and no synchronisation with marketplaces. The quality of your feed directly determines your visibility. An incomplete or incorrect feed leads to rejected products, a lower Ad Rank and missed sales. In a competitive market where buyers compare prices and stock in real time, an optimised feed is not a ‘nice-to-have’ but an essential requirement.

What a product feed delivers for SME online shops

With a well-structured product feed, you can reach buyers the moment they show search intent. Your products appear in Google Shopping results – often above organic search results – complete with images, prices and reviews. This increases the click-through rate and attracts motivated visitors. In addition, you can use the same feed forremarketing campaigns, in which you show visitors products they have previously viewed. For SME online shops with 200 to 5,000 products, an automated feed setup is essential: manual updates are not scalable. At Monkey Vision , we link feeds to your online shop platform and optimise titles, categories and attributes for maximum visibility in Shopping campaigns. This way, you get more value for every pound spent on advertising.

A product feed is more than just a technical file for Google Shopping. You can use the same feed for marketplaces, social commerce, remarketing and even internal analysis. Below, you’ll find four specific scenarios in which SME online shops use the feed to boost turnover, plus guidance on when a feed is – or isn’t – the right choice.

Google Shopping and Microsoft Shopping Ads

The most common use case: you upload your product feed to Google Merchant Centre and link it to a Shopping campaign in Google Ads. Your products appear in the Shopping tab and at the top of search results when someone searches for a product category or brand name. Microsoft offers a similar channel via the Microsoft Merchant Centre. For example, an online shop with 800 sports items can set up a separate campaign for each product group, with its own budget allocation and bidding strategies. The advantage: you only pay for clicks, and the buyer can see the price and image before clicking, which increases the likelihood of a conversion. Incorrect feeds will result in products being rejected straight away. Ensure that the GTIN, brand and product type are entered correctly in accordance with Google’s specifications.

Marketplaces such as Bol.com, Amazon and Zalando

Many marketplaces require a product feed to import your product range. Bol.com, for example, uses its own feed format which you can submit via the Seller API or a plugin. You automatically send product information, stock levels and prices, so you don’t have to enter each product manually. For a toy shop with 1,200 items, this saves hours of work every week. Please note: each marketplace has its own requirements regarding attributes, categories and image formats. A feed that works perfectly for Google Shopping often needs to be adapted for Bol.com or Amazon. Use a feed management tool or an API integration to customise feeds per channel without duplicating effort.

Dynamic remarketing and social commerce

You can link your product feed to Facebook and Instagram to display dynamic product adverts to visitors who left your site without making a purchase. The feed automatically populates the advert with the product the visitor viewed, including the current price and stock levels. A furniture shop can, for example, show someone who viewed an armchair an advert three days later featuring that same chair, plus additional models. This increases retention and reduces the cost per acquisition. TikTok and Pinterest now also support product feeds for shoppable content. Here, the feed is used as a personalisation engine: each channel selects the right products based on user behaviour. Without a feed, you would have to put together every advert manually, which is unfeasible when dealing with hundreds of products.

Internal analysis and product range optimisation

A lesser-known application: use your feed as the basis for internal dashboards. By combining feed data with web analytics, you can see which products get lots of impressions but few clicks, or which categories are underperforming. A DIY shop discovered in this way that products without a brand name in the title received 40 per cent fewer clicks. They adjusted the feed, added brand names and immediately saw an increase in CTR. You can also use the feed to test pricing strategies: increase the price of a product group in the feed, monitor the effect on conversion rates and revert to the original price if it doesn’t work. In this way, the feed becomes a live testing environment for product range decisions.

When a product feed is the right choice and when it isn’t

A product feed is useful if you have at least 20 products and want to actively advertise or sell via external channels. From 100 products onwards, an automated feed becomes essential. Do you have fewer than 10 products or do you only offer services? In that case, a feed is unnecessary. A feed also does not work well for fully bespoke products without a fixed price or stock: the feed expects standard attributes. In that case, landing pages with forms are more effective. Do you have a product range but lack the time or expertise to optimise feeds? Then consider an SEO strategy or content marketing as an alternative, or engage a specialist for feed management.
