gmvlySelf serve CSS for PPC leads
Work towards growing your gross merchandise value with more auction bidding power. Make your existing Shopping budget work harder while your PPC team keeps control of campaigns, bids and product feed. Moving from Google Shopping CSS removes its bid margin, giving you more auction bidding power at the same bid. You continue to fund your ads; GMVLY provides the CSS connection at a predictable price.

The CSS bidding advantage
Moving from Google Shopping CSS removes its 20% bid margin. Choose how to use that advantage: reduce your bid, or keep your previous bid and put more of it into the auction.
Your starting point with Google Shopping CSS
£1.00
Your previous bid
− £0.20
20% Google Shopping margin
= £0.80
Effective auction bid
Option 1 · Lower your bid
20% less
Bid £0.80 through GMVLY instead of £1.00 through Google Shopping CSS. The same £0.80 enters the auction.
(£1.00 − £0.80) ÷ £1.00 = 20% lower bid
Option 2 · Keep your previous bid
25% more
Keep your £1.00 bid through GMVLY. The full £1.00 enters the auction, compared with £0.80 previously.
(£1.00 − £0.80) ÷ £0.80 = 25% more bidding power
Two ways to use the same advantage; the percentages do not add together. The 20% reduction illustrates the bid needed for equivalent auction value, rather than a guaranteed 20% reduction in your actual CPC. Actual click costs and results depend on auction conditions and bidding strategy. Another independent CSS may already provide this advantage. Read Google’s CSS explanation.

Use both
Keep your existing CSS for core campaigns and add GMVLY as another CSS to fund campaigns aimed at long-tail demand. If you choose to run your own campaigns through GMVLY Self serve CSS too, its standard subscription price applies to your own campaigns.
Combined option
Your own campaigns + GMVLY-managed campaigns
You fund your own ads; GMVLY funds the campaigns we run. You pay the agreed CPA on completed GMVLY-managed sales. If Managed CSS is active, Self serve CSS is billed separately at its standard price.
Compare all optionsYour team or agency continues to manage campaigns, bids, ad spend, reporting and product feed. GMVLY supports the CSS connection. For GMVLY-funded campaign management, explore Managed CSS.
You may already receive the same auction advantage. Compare subscription price, support, account requirements and terms when deciding whether to switch.
GMVLY staff activate billing after the CSS switch is verified and a payment method is saved. That activation starts the initial 30-day trial. Saving a card or reaching Verified status alone does not start it. The first subscription charge follows the trial. Additional Merchant Centers update your subscription rather than starting another trial.
Verified direct admin access to the Merchant Center is required to submit a self-service switch request. We confirm the account and connection steps before making changes.
Contact us to arrange subscription cancellation and account exit steps. Cancelling billing does not automatically move your Merchant Center to another CSS. We confirm the relevant terms before activation.
The products are billed separately. Self-service uses its standard subscription price; Managed CSS uses an agreed commission on completed sales from the campaigns GMVLY runs.
Tell us about your Shopping targets, current CSS and Merchant Center. We will confirm whether switching to GMVLY fits your setup. If you want us to fund and manage a separate sales route, ask about Managed CSS.
