Best Google Ads Agencies for Shopify Stores (2026)

Every agency on this list will tell you they drive results. The differences that actually matter show up in four places, usually before you ever get to a case study.

Account ownership. You want the Google Ads account and Merchant Center created under your own login, with the agency added as a manager. If an agency owns the account instead, switching later means starting your conversion history over from zero.

Feed management depth. For Shopify specifically, most of the real work in Shopping and Performance Max happens in the product feed, not the bid strategy. An agency that treats Merchant Center as an afterthought will underperform one that actively manages titles, GTINs, and custom labels.

Pricing model. Percentage of spend, flat retainer, and hybrid models all show up on this list. A percentage model can create an incentive to keep raising your budget rather than your efficiency, which is worth asking about directly before signing.

Who actually touches your account. Some of these agencies run 200 or more active clients through a layered team of account managers and specialists. Others cap client count and keep the same senior person on the account for the life of the relationship. Neither structure is wrong on its own, but you should know which one you're buying.

A fast read on where each option actually fits before the full breakdown below.

Tinuiti is the largest independent performance marketing firm managing the Google, Meta, and Amazon triopoly, with more than $4 billion in digital media under management and Google Premier Partner status for the 12th consecutive year. For a Shopify store, that scale is the whole pitch: Search, Shopping, Performance Max, YouTube, and Display all run under one media operating system called Bliss Point, with the same team able to handle Amazon and connected TV if the brand sells there too.

That scale comes with a floor. Tinuiti's client roster skews toward brands like Poppi, Olly, Etsy, and Converse, businesses already spending well into six figures a month across channels. A Shopify store doing $8,000 a month in Google Ads is unlikely to get much attention here. This is the agency to call once a Shopify brand has outgrown a single-channel specialist and needs one operator across every paid channel it runs.

Common Thread Collective built its reputation as a Shopify-native DTC growth agency, and its current product, the Prophit Engine, reflects that positioning directly. Instead of selling Google Ads as a standalone service, CTC pairs a dedicated media buyer with forecasting software that tracks a brand's entire P&L, not just ad account metrics, with Google and Meta ad buying as two pieces inside one growth system alongside creative production and incrementality testing.

The client list, including Liquid Death, Native, Theragun, and Girlfriend Collective, points at brands doing meaningful revenue, generally cited in the $2 million to $30 million a year range. This is a strong fit for a Shopify brand that wants a single accountable partner across paid media and forecasting rather than an ads-only vendor, and a weaker fit for a store that just wants someone to run Search and Shopping without the broader growth-system commitment.

Disruptive Advertising manages over $300 million in annual ad spend from its Utah headquarters, with a reputation built on rebuilding accounts that are already spending real money but underperforming. Their process leans hard on account audits that isolate wasted spend before scaling anything, then layers conversion rate optimization on top of the media buy rather than treating the two as separate workstreams.

That audit-first, CRO-heavy approach suits a Shopify brand that already has real traffic and conversion data but suspects a meaningful share of the budget is being wasted. A brand new store with no conversion history yet won't get much value from an approach built around fixing what's already broken.

KlientBoost is worth including with an honest caveat: its core positioning, on its own site, is B2B and SaaS lead generation, not ecommerce. Ecommerce is one of several verticals it serves alongside Shopify, Magento, WooCommerce, and BigCommerce, and its case studies and messaging lean toward pipeline and revenue attribution rather than ROAS on a product catalog.

Where it fits a Shopify store well is the bundling. Every KlientBoost engagement includes conversion rate optimization and landing page testing alongside the Google Ads management itself, backed by 750+ five-star reviews and Google Premier Partner status. If a Shopify brand's real bottleneck is the product or landing page experience rather than the ads themselves, that bundled CRO work is the differentiator. If the brand just needs Shopping and PMax run well, a more ecommerce-native option on this list is probably a tighter fit.

SmartSites is a full-service digital marketing agency out of New Jersey, founded in 2011, with over $100 million in client revenue generated and 300+ five-star Clutch reviews. For Shopify specifically, SmartSites runs Google Shopping, Meta, TikTok, YouTube, and Performance Max alongside SEO and web design, with a Shopify partner integration list that covers most of the common ecommerce stack including Klaviyo, Gorgias, Okendo, and Yotpo.

Pricing starts in the $2,000 to $3,000 a month range, which puts it within reach of Shopify brands that have product-market fit but aren't yet at the scale where they need an enterprise operation. The tradeoff of a full-stack agency is the same as always: one team across several disciplines rather than a specialist devoted only to paid search.

OuterBox has run digital marketing since 2004, and its specific strength for a Shopify store is Google Shopping feed management. Their team handles Merchant Center integration, product data cleanup, GTIN and attribute fixes, and ongoing feed error resolution as a distinct service line rather than a side task bolted onto Search campaign management, alongside standard Search, PMax, Display, and YouTube.

That feed-first approach matters more than it sounds. A broken or thin product feed is one of the most common reasons Shopping and PMax underperform on Shopify specifically, since Shopify's native product data often needs real cleanup before it's ready for Google Merchant Center. A brand with a large or messy catalog will get more direct value out of OuterBox than a brand with 20 clean SKUs.

I'll be direct here since this is my own agency: Online Labs is a fit for a specific kind of Shopify brand, not every one. I manage a maximum of 6 clients at a time, personally, with no account managers or handoffs, the opposite structure from most of the agencies above. That model works well for a premium or high-ticket Shopify store (fine jewelry and luxury goods are where I've done the most direct work) spending $5,000 or more a month, where the person managing the account needs to understand margin, average order value, and a longer consideration cycle rather than optimizing for volume alone.

The proof point I can share without violating an NDA: I scaled a fine jewelry retailer's Google Ads account 18x, hitting a 680% peak ROAS with 4.5x sustained across the engagement. On the ecommerce side more broadly, a travel brand I worked with saw cost per booking drop 32% with bookings up 2.1x, and getting there started with fixing conversion tracking on Shopify, which is where I start on nearly every new account. If a Shopify brand wants the same senior person on the account for the life of the relationship and is spending at or above that $5,000 floor, that's the fit. Below that floor, or if you want a larger team with more channels bundled in, one of the other options on this list will serve you better. Running a jewelry or luxury store specifically? I compared the best Google Ads agencies for jewelry and luxury brands in a dedicated breakdown.

Dennis Moons runs Store Growers, and it's worth being precise about what this actually is: not a Google Ads management agency in the sense of the other seven options here, but a coaching and education business. Moons has managed Google Ads campaigns for over 13 years and more than $5 million in ad spend across 200+ clients, and Store Growers now sells courses, a paid coaching membership, and one-hour consultation calls at $400 rather than ongoing account management.

That makes it the right fit for a specific situation: a Shopify store owner who wants to run their own Google Ads account and needs structured training or an experienced second opinion, not someone to hand the account off to. If you're looking to outsource management entirely, this isn't that. If you want to learn to do it yourself with a credible teacher behind the material, it's worth the $400 for a single strategy call before committing to a full course.

Four decisions, in order, get you to the right answer faster than reading every case study on every site above.
