How can you benefit from the CSS program for Google Shopping Ads?
Switching your Merchant Center from Google CSS to a CSS partner such as verteco.shop cuts your CPC by 20%. That's the headline, and it's true. What the discount actually does inside your campaigns is less obvious, though, so let's walk through the mechanics and the two main ways to put the saving to work. We run our own Google CSS, so these are questions we field all the time.
How the Discount Mechanism Works
Google grants CSS partners such as verteco.shop a 20% discount on CPC (cost-per-click). The point of the discount is to level the playing field against Google's own Shopping CSS. As in the rest of Google Ads, shopping campaigns are decided by an auction, and advertisers bid the cost per click they're willing to pay.
Concretely: a €0.80 bid placed through a CSS partner carries the same weight in the auction as a €1.00 bid placed through Google Shopping CSS. Turn that around and it means an advertiser bidding through Google Shopping has to go 25% higher to match a bid coming in through a CSS partner.
Where the Discount Shows Up
The question we hear most often: where does the discount actually appear in the account? The short answer is that it doesn't. Google neither refunds the 20% nor displays it anywhere in Google Ads. What you get is a bidding advantage over Google CSS, equivalent to staying with Google CSS and raising all your bids by 25%. In practice your products win better positions and enter more auctions, so your campaigns pick up more impressions.
Merchants who switch to a CSS partner like Verteco.shop tend to see clicks climb noticeably.
Better still, those extra clicks arrive while the campaigns' CPC falls.
Putting the 20% Discount to Work
You can spend the discount in one of two ways: push more revenue through your shopping campaigns, or make the same campaigns more profitable.
- Boost Revenue
Happy with your ROI (return on investment) and ROAS (return on ad spend), but hungry for volume? Leave your bids alone. Impressions and clicks will climb by themselves after the switch. One caveat: the extra volume comes from broader, less targeted search terms higher up the funnel, so expect a lower click-through rate (CTR) and a weaker conversion rate on that new traffic. This route makes sense when your ROI has some breathing room and growth is the priority.
- Enhance Profitability
If your ROI is tight and the aim is lower costs, trim your bids slightly, somewhere in the 10%-20% range, and let the discount cover the difference. Plenty of accounts have held their volume this way while paying less for it.
For most advertisers we recommend starting with strategy 2: take the profitability gain, hold on to your volume, and keep a close eye on campaign revenue while things settle.
Automated Bidding (Target ROAS / Target CPA / Smart Shopping) with a Google CSS Partner
Campaigns running on Google Ads' automated bidding (target ROAS / target CPA / Smart Shopping) receive the same bidding advantage once they move to a CSS partner like verteco.shop. The catch is control. Automated optimization leaves you fewer levers, so CPC and impressions are harder to steer than under manual bidding. Keep your CPA or ROAS target where it is, and the algorithm will adapt to the new conditions by itself, which over time means more conversions and more revenue at the same CPA or ROAS.
If you'd rather bank the saving, set a lower CPA target or a higher ROAS once you're connected to verteco.shop, and you'll reach similar conversion and revenue numbers with less spend.
One honest warning about the transition. Automated campaigns need time to adjust after the switch, and the early results can be disappointing. The algorithm doesn't instantly register that its bidding power has changed, so impressions and clicks often spike right after the move. Then it starts compensating and spends a while searching for the right bids. Don't be alarmed if the campaigns wobble before they find their balance again.
Also worth remembering: automated bidding only ever chases the goal you set, ROAS or CPA. That makes the effect harder to spot than under manual bidding. CPC might not visibly drop. Volume might not visibly rise. The system decides where the advantage goes, and given a little time it converts the extra bidding power into additional conversions or revenue, in line with your ROAS or CPA goal.
The short version: a CSS partner such as verteco.shop gives your Google Shopping campaigns a real edge. Spend the 20% CPC discount on growth or on margin, whichever your goals and your ROI demand. Automated campaigns benefit just as much from the switch. They simply need that adjustment window before the results come through.
Whatever you optimize for, watch your campaigns closely and adjust your bids as the data comes in. Growth, profitability, or a bit of both: the CSS program hands you a competitive advantage that keeps working for your Google Shopping Ads over the long run.
