Get Started

Knock 20% off of your CPC


RedBrain is a premium Google Comparison Shopping Service, so partnering with us gives you the perfect opportunity to gain hefty discounts on your Google ad spend. No strings attached.

Did you know that when you spend £1 directly with Google, the first 20p goes straight into the pockets of the Google Shopping advertising sales team? Just 80p of your £1 bid continues its journey to auction where it competes for the best ad space for your products. Using RedBrain to host your shopping feed erases this hidden fee, so, even if you change nothing else, you get a 20% discount and pay only the 80p that ends up at auction – simply by using our CSS.

The perks of CSS extend way beyond savings


An often overlooked differentiator between CSSs is their Comparison Shopping website! Using a CSS may be used to drive down CPCs through our 20% saving, however you can benefit from increased exposure on the CSS website.

Lots of CSSs have started in the last year to try and capitalise on CPC savings – but without any of the traffic that established CSSs have spent years building.

RedBrain has run CSS websites for over nine years and we have 25 million unique visitors a month just on our websites. No other CSS currently has close to that many users, and none can put you in front of so many potential customers. Why not ask your CSS provider how many visitors they will send to you from their CSS website, and then get in touch to see what we can do for you?


Want to leave the feed optimisation to RedBrain?

If you prefer a fully managed service where we handle the admin of your product feeds and shopping accounts, then our AI Shopping Service might be just what you’re looking for.


What we offer

Service, simplified


The RedBrain Hub takes our Premium CSS service to the next level. Giving you full control for billing, setup, onboarding new accounts and migrating existing ones. You can get up and running with CSS in a couple of clicks – with no complicated forms to fill out, no long delays or hour long phone calls. Just login, select the existing accounts you want to use and let RedBrain do the rest.

More to our Premium CSS service than meets the eye


Rather than creating a one-size-fits-all pricing structure, we offer additional services on top of Premium Self Service CSS access to help you take your Google Shopping further.

We’re one of only a few Premium CSS partners, meaning that RedBrain’s your best option for enhanced support alongside Google. Shopping Industry trend reporting, price benchmarks and account deep dives all come as standard, and additional services like Product Feed optimisation can take your performance to the next level.


Product feeds are the lifeblood of Shopping campaigns. While lots of companies may consult with you and tell you their opinions on how to boost performance, we spend tens of millions of pounds of our own money every year buying traffic with our product feeds.

We test optimisations, tips, tricks and industry whispers on a daily basis across 3.5 million merchant centres to ensure we get the most out of every penny spent.

From enriching products with missing attributes, to optimising titles for search impressions, or even upgrading your product images with AI – we can show you the opportunities we see in your feed and let you choose which recommendations you’d like to move forward with.

Are you keeping up with your competitors? There’s hundreds of retailers with the same product, so how do ad platforms decide the five offers to show customers and how do you make sure you’re one of them?

Price benchmarking. If your products are significantly overpriced compared to the competition then ad networks won’t show it, and even if the products are shown the chances are users will click on your competitors.

We can give you product price benchmarking across your catalogue, showing you how many clicks you’re likely missing out on due to price. We can prioritise reporting by the biggest price differential, or by the products missing out on the most clicks.

We have thousands of Google Ads accounts live and have to track changes on a daily basis. From almost a decade of running our own campaigns, we’ve developed tools and techniques to help us gauge the health of an account within moments.

We look at over 60 performance characteristics, from the % of products getting ad impressions to ROI and impression share across individual items and whole campaigns. We summarise product performance on scales from 1 to 5 so you can see potential problems as well as RedBrain recommendations on how to get more out of your existing account.

Staying ahead of your competitors is critical to successful campaigns. At RedBrain, our campaigns deliver 1 billion ad impressions weekly – with auction insights from over 25 billion bids weekly.

We will never share specific account performance, but we’re able to give you competitor analysis based on our market insights. We work with 35,000 retailers across North America and Europe, and not only monitor our own performance but that of all the competitors in auctions. We can see where you’re missing out due to bids, poor product data, or new channels like Facebook/Bing that you may not have reached with your in house campaigns.

A Comparison Shopping site should align with your brand and help drive you to increased CTR. One lesser known advantage of the CSS program is that Google has given every retailer a new ad extension to help optimise their Shopping Ad performance. If you’re a Fashion retailer, which CSS is going to bring you the best click through rate?

  • Catwalk (owned by RedBrain)
  • RedBrain (our main CSS)
  • Motormart (another RedBrain owned CSS)

RedBrain has 4,000 price comparison sites across the world. We’ve been running price comparison sites for almost a decade, so we can help you find a CSS that matches your brand and your target audience.

You may be looking for a Premium CSS partner, but there’s more to the world of shopping than just Google Ads. With RedBrain as your CSS partner, you can expand your campaigns to include Bing, Facebook, Pinterest and more!
