Google Merchant Centre and Free Listings

31st Jul 2025

Google Merchant Centre

Most people who engage with us know about SEO (search engine optimisation) and its importance. However, many new customers and contacts are not aware of Google Merchant Centre (or to give it the official US English name, Google Merchant Center).

Those Realnet customers with online product catalogues and ecommerce are set up with an account as a matter of course and in this article, we explain why.

It’s Free

Since Google reintroduced free Shopping listings in 2020, GMC has become a key gateway for retailers of all sizes. Through a Merchant Centre account, businesses can upload product feeds. This provides detailed information about each item including title, image, price, availability, and more. Once verified and approved, these products can not only appear organically in Google’s Shopping tab, they can also appear in general search results when users look for relevant terms.

This means businesses can reach millions of potential customers without spending a penny on advertising. For smaller retailers, it levels the playing field against larger competitors, allowing them to benefit from Google’s massive reach and consumer trust. GMC also supports structured data, so Google understands exactly what a product is and can match it accurately with search queries.

Other Reasons to Maintain and Monitor Google Merchant Centre

Beyond unlocking free listings, keeping your GMC account healthy and up-to-date is vital for a number of strategic reasons:

Eligibility for Paid Google Shopping Ads
Google Shopping campaigns, a major driver of paid ecommerce traffic, requires a connected and compliant Merchant Centre feed. Errors or inconsistencies in product data can lead to disapprovals, reducing the reach of paid campaigns.

Performance Insights & Diagnostics
GMC provides performance metrics and issue diagnostics for your product data. This highlights problems with feed quality, pricing mismatches, policy violations, or site errors. Proactive monitoring helps keep listings live and eligible in Google while flagging up any potential problems with product data on your website.

Dynamic Remarketing & Local Inventory Ads
With a linked GMC and Google Ads account, businesses can run dynamic remarketing campaigns, showing past site visitors the exact products they viewed. For physical retailers, Local Inventory Ads show stock availability at nearby stores, directly in Google Search.

Brand Credibility and Shopping Trust
Products listed through GMC often benefit from richer, more credible presentation. Shoppers see trusted elements like ratings, seller names, delivery times, and pricing directly in results. This in turn improves clickthrough rates and conversions.

The Bottom Line

GMC now integrates with platforms like Shopify and WooCommerce, making it easier than ever to sync your inventory across Google and other ecommerce platforms.

Whatever products you are selling and whatever your size, leveraging the benefits of Google Merchant Centre should be a ‘no-brainer’! With the rise of visual shopping and Google’s growing emphasis on product-rich results, setting up and maintaining a well-optimised GMC account ensures that your business is discoverable, competitive, and ready to convert.
