Google Ads agency for Shopify stores: revenue that pays off

A Google Ads agency for online shops works with different levers than an agency for service businesses: it manages orders with basket value, margin and return rate, not enquiries. Rankist runs Google Ads for Shopify shops in Switzerland, Germany and Austria, together with SEO, Meta Ads and email from one team.

Why a Google Ads agency works differently for shops than for service businesses

A dental practice books search ads on a handful of terms and measures phone calls. A shop with 400 products has 400 landing pages, 400 prices and stock levels that change every day. That is why a large share of revenue comes from Shopping ads with image, price and shop name directly in the search results. The foundation is the product feed from Shopify, which is checked in Google Merchant Center. Performance Max builds on that: Google distributes your budget automatically across Search, Shopping, YouTube, Display and Gmail. This requires clear signals, otherwise the algorithm optimises for cheap clicks instead of profitable orders.

Search campaigns remain important, but targeted: for your brand name, so no competitor bids on it, and for category terms such as "buy leather handbag", where users do not yet have a specific product in mind. A Google Ads agency for online shops keeps these levels separate instead of putting everything into one campaign.

Google Shopping agency: the feed decides your success

A Google Shopping agency spends more time in the feed than in the ad copy. Google only shows your products if title, GTIN, brand, price, availability and shipping costs are passed on correctly. Typical mistakes we see in practice: product titles start with the brand name instead of the search term, variants share one image, shipping costs in Merchant Center do not match the checkout.

We add missing attributes directly in the Shopify product data, so that feed, shop and SEO draw on the same source. Organic visibility, which our Shopify SEO agency looks after, benefits from clean product titles as well.

What a Google Ads agency sets up before the first campaign

Most accounts we take over do not have a reporting problem but a tracking problem. Browsers block cookies, users decline consent, and Google only sees a fraction of the orders. Clean Google Ads conversion tracking for Shopify therefore runs server-side through a dedicated tagging server, respects the consent decision and passes on the order value correctly in CHF or euros.

Before the first franc of budget is spent, we check these points:

• Conversion tracking with server-side tagging, Consent Mode and reconciliation against Shopify orders
• Feed quality in Merchant Center: disapprovals, missing GTINs, price mismatches
• Campaign structure by margin and product range rather than by what is convenient in the account
• Negative keywords for terms such as "free", "used" or "instructions"
• Targets based on contribution margin: a product with a 15 percent margin can carry different bids than one with 60 percent

The last point matters most. If you only give Google revenue as a target, you get revenue, even at a loss. If you build margins into the controls, you get orders that pay off.

Google Ads agency and SEO from one team

Google Ads brings revenue from day one, SEO takes months and then keeps growing in the background. Each channel delivers data the other needs: from the campaign search terms we see which categories convert, and build content there. From the rankings we see where organic visibility already carries its weight and budget can be shifted. If the two channels sit with different agencies, this exchange is lost.

At Rankist, Ads, SEO, Klaviyo and shop development sit in one team. A landing page built for SEO becomes the destination for Shopping campaigns, and newsletter subscribers from Ads purchases bring repeat orders without click costs.

Google Ads management: what happens every week

Google Ads management is not a setup followed by silence. Every week we review search terms, move budget between campaigns, pause products that are out of stock and test ad copy. Seasonality matters more for shops than for service businesses: bids for winter products rise in October, gift ranges need reach in November, and on Black Friday click prices double in many categories.

The reporting shows orders, contribution margin per campaign and new customer share, reconciled with Shopify Analytics. One Shopify Plus brand managed by Rankist grew from 9 to 34.7 million euros in revenue within twelve months following this logic, an increase of 285 percent according to Shopify Analytics. Google Ads was one part of that, alongside SEO, email, product range and a shop rebuild. Results like these cannot be promised, the way of working can.

Where a Google Ads agency hits its limits: CBD, nicotine, alcohol

Google heavily restricts or bans advertising for certain product groups. CBD and hemp products, nicotine such as snus and vapes, and alcohol in many countries can hardly be advertised through Shopping and Performance Max. We say this openly in the first conversation instead of setting up an account that gets suspended after three weeks. For these industries the path is organic visibility plus email: with Shinygram, Heimat, Green Passion, Canapuff and Snus-Shop we manage several brands that grow without Google Ads. Our page on the SEO agency for CBD shops describes how this works.

Google Ads costs: what determines the effort

Google Ads costs consist of the ad budget, which goes directly to Google, and the effort for setup and management. Both depend on your situation: how many products and variants does the shop have, in how many countries and languages do you advertise, is there already tracking and a clean feed, how competitive is your category? In the first conversation we look at your account or your starting position and give you an assessment of budget and management effort.

Google Ads agency Switzerland: bids in CHF, three languages, clear target regions

A Google Ads agency in Switzerland has to solve some things differently than in Germany. Bids and conversion values run in CHF, so Performance Max does not calculate with exchange rate noise. A campaign for French-speaking Switzerland needs French ads, keywords and landing pages, not translated German ones. If you only ship within Switzerland, you exclude Germany as a target region, even if the search terms are identical. If you sell into the EU, you separate campaigns by country because of customs, shipping costs and prices. TWINT in the checkout, prices with rounding to 5 Rappen and correct shipping details in Merchant Center are details Swiss buyers expect. As a Shopify agency we implement these points directly in the shop, not just in the ad account.
