Ecommerce PPC Agency

The ecommerce PPC agency that turns clicks into revenue

An ecommerce PPC agency for Shopify and DTC brands. Most agencies split media buying and landing pages across two teams that never talk. We run paid search and post-click conversion as one accountable program: Google Ads, Microsoft Ads, and Performance Max feeding directly into landing pages built and continuously tested to convert that exact traffic.

  • Senior media buyers, not junior reps on a dashboard template
  • Landing pages built + tested for paid traffic specifically
  • Pay tied to ROAS, not just ad spend managed

About Conversion

A pay-on-results agency that runs media buying and landing pages as one loop

  • San Francisco, USA

    In-house team

  • Pay-on-Results

    Tied to ROAS

Conversion is a pay-on-results growth agency headquartered in San Francisco and a Shopify Plus Partner. We work with Shopify/DTC ecommerce brands, B2B companies, and healthcare practices running Google Ads, Microsoft Ads, and paid search campaigns who are tired of paying for clicks that land on pages that don't convert. Stores that need feed and Merchant Center work on Shopify specifically can start with our Shopify PPC agency service, and targets are set from margin, as our break-even ROAS guide explains.

What separates us from a generic large agency is structural: your media buyer and your landing page team are the same team, working off the same weekly data. Every dollar of spend feeds into a landing page built and continuously tested to convert that specific audience, device, and intent, using the methods in our guide to A/B testing vs multivariate testing. No handoffs, no waiting six weeks for a dev sprint to fix a broken funnel. The same team can extend the work into site-wide conversion rate optimization, an SEO program that builds organic traffic alongside paid, or a full-funnel growth marketing engagement.

Why most PPC engagements underperform

Great media buying can't fix a landing page that leaks

We've audited hundreds of paid search accounts. The same three structural problems show up whether the incumbent is a freelancer, an in-house hire, or a large agency.

  • Media buying and CRO are two vendors that never talk

    The agency running your Google Ads has no say in the landing page, and whoever owns the website has no visibility into which campaigns are sending which traffic. Nobody is accountable for the number that matters: revenue per click. We run both functions as one team with one weekly scorecard.

  • Paid budget lands on a generic homepage or PDP

    Search and Shopping traffic gets routed to the same page organic and email traffic sees: same headline, same offer, same proof points, regardless of the keyword or ad that earned the click. We build and test landing pages matched to specific campaigns, audiences, and intent.

  • You're paying for spend managed, not results delivered

    Most agencies bill a flat retainer or a percentage of ad spend. They get paid more when you spend more, regardless of ROAS. Our pay-on-results structure ties our fee to incremental revenue and ROAS, which means we're incentivized to cut wasted spend.

Our process

From account audit to compounding ROAS in 14 to 90 days

  1. Step 01

    Audit & tracking rebuild

    Full audit of existing Google/Microsoft accounts, feed health, and conversion tracking. Most accounts we inherit are undercounting conversions 15 to 40%, so we fix tracking before we touch a single bid.

  2. Step 02

    Restructure & first landing page

    Campaign architecture rebuilt around your margin and sales cycle. First campaign-matched landing page ships within 14 days, wired with a testing framework from day one.

  3. Step 03

    Test & iterate

    Weekly optimization cycle across bids, creative, audiences, and landing page variants. Every test is tied to a hypothesis and a statistically significant sample before we call a winner.

  4. Step 04

    Scale what's proven

    Budget shifts toward what's compounding ROAS: winning campaigns, winning landing page variants, winning audiences. Reporting ties every dollar to revenue.

Frequently asked

PPC conversion optimization questions

What does a PPC conversion optimization agency actually do?
A PPC conversion optimization agency runs paid search media buying and the landing pages that traffic lands on as one connected program, instead of splitting them across two vendors. That means Google Ads, Microsoft Ads, and Performance Max campaign strategy, bidding, and creative sit in the same room as landing page design, copy, and A/B testing, so every dollar of spend is judged on post-click conversion rate as well as click-through rate and cost-per-click.
How much does PPC management cost?
In the US market, standalone PPC management typically runs $2,500 to $8,000/month for accounts spending under $20K/month in media, and $8,000 to $20,000+/month for larger accounts, often billed as a flat fee or 8 to 15% of ad spend. Add landing page CRO (design, dev, and a continuous testing program) and a fully connected PPC + CRO engagement usually runs $6,000 to $25,000/month depending on account complexity, number of landing pages in test, and platforms covered. Conversion offers a pay-on-results structure tied to incremental ROAS for qualifying accounts. Get a fixed quote in 48 hours after a 30-minute call.
What's a good ROAS for a paid search campaign?
It depends on your margin structure. As a rough band: ecommerce brands with healthy margins typically target 4 to 6x blended ROAS across the account, with branded search often clearing 10x+ and cold prospecting campaigns running 2 to 3x while they build a remarketing pool. B2B and healthcare lead-gen accounts usually aren't judged on ROAS at all. Cost-per-qualified-lead and lead-to-close rate matter more. We set your target off your contribution margin and CAC payback window in the first strategy call.
Is there a minimum ad spend to work with your agency?
Most of our PPC + CRO engagements start with accounts spending $15,000+/month in combined Google and Microsoft Ads media (separate from our management fee), since that's roughly the volume needed to run statistically meaningful landing page tests alongside the media program. We make exceptions for high-intent B2B and healthcare accounts where lead value is high even at lower click volume. Under that threshold, our Shopify Marketing Agency retainer is usually a better fit since paid search is one of several channels running in parallel.
How does landing page CRO improve paid media ROI, and do you build the pages?
Paid search ROI is a function of two numbers: cost per click and post-click conversion rate. Most agencies only control the first one. A landing page built and continuously tested for the specific traffic segment it receives (matching ad copy to headline, cutting form or checkout friction, reordering proof and objection-handling for that audience's intent) routinely lifts conversion rate 20 to 60% without touching bid strategy. We build the pages ourselves: our designers and developers ship landing pages directly on Shopify, WordPress, Unbounce, Webflow, or a headless stack, with the testing infrastructure wired in from day one.
Should we build an in-house PPC team or hire an agency?
In-house makes sense once you're spending $75K+/month in media and can justify a senior media buyer, a CRO/design resource, and an analytics hire as full-time roles. Otherwise you're paying full salaries for part-time attention. An agency gives you senior-level media buying and landing page CRO from day one, cross-account pattern recognition across multiple advertisers, and no hiring risk. Many of our clients run a hybrid model: an in-house marketing lead who owns strategy and brand, with our team executing media buying, landing page builds, and testing.
Do you manage Microsoft Ads (Bing) as well as Google Ads?
Yes. Microsoft Ads is underpriced traffic for most advertisers: lower CPCs, less competition, and an audience that skews older and higher-income in several verticals, especially B2B and healthcare. We run it as a standard part of the program, typically allocating 10 to 20% of search budget there once Google campaigns are stable, and scaling it further where the CPA data supports it.
How long until we see results?
Conversion tracking and account audits are typically complete in week one. New or restructured Google/Microsoft campaigns start serving in weeks 2 to 3. The first landing page test usually goes live within 14 days of kickoff. Statistically significant lift in ROAS and post-click conversion rate is usually visible by day 60 to 90, once we've cycled through 3 to 5 landing page test iterations and the account has enough conversion data to bid efficiently.
What's the difference between this and the Shopify Marketing Agency service?
Our Shopify Marketing Agency service is a full-funnel program for Shopify and Shopify Plus DTC brands: Meta and TikTok ads, Klaviyo email/SMS, SEO, and CRO all running together, with paid search as one channel inside that bundle. This PPC Conversion Optimization service is for brands on Shopify or any other platform, DTC or B2B or healthcare, who need dedicated paid search management and landing page CRO as their own accountable program. If you're on Shopify and want everything under one roof, start with Shopify Marketing. If you need a focused PPC + landing page team, this is the right page.
How do you handle conversion tracking and attribution?
Every engagement starts with a tracking audit and rebuild: GA4 configuration, server-side tagging via Google Tag Manager server container or a CAPI-style setup for Google and Microsoft, offline conversion imports for sales-assisted and B2B pipelines, and a documented attribution model everyone agrees on before we optimize a single campaign. Most accounts we inherit are undercounting conversions by 15 to 40% due to broken client-side tags, ITP/cookie loss, or missing offline conversion import. Fixing that alone often changes which campaigns look profitable.
Do you work with B2B lead-gen accounts, or only ecommerce?
Both. Roughly half our PPC book is ecommerce (Shopping, Performance Max, dynamic remarketing) and half is B2B and healthcare lead-gen (Search, call tracking, form and booking conversion optimization). The media buying principles are similar. The conversion event, sales cycle, and landing page psychology are very different, and we structure campaigns and pages around whichever one your business runs on.
