PR Is the E-Commerce Growth Lever Your Ad Account Can’t Show You

How does PR support e-commerce growth beyond paid ads? A regulated consumer product e-tailer we’ve worked with for 2 years hit its most interesting data point 12  months into a new phase of the relationship. When paid ads went live, the team braced for the usual side effect: branded search terms filling up with “coupon,” “discount,” and “promo code.” That’s what happens when you turn on paid acquisition for a brand that hasn’t built trust first. Buyers show up looking for a deal because a deal is the only thing you’ve given them as reason to trust.

Instead, branded and direct visits climbed 93% year over year. Branded search paired with discount language dropped 50%. New and returning purchasers combined rose 83% year over year. The trust and reputation the brand built scaled with ads; PR brough the trust and reputation, ads brought the scale.

That’s the piece most DTC and e-commerce marketing plans miss. Paid media buys reach. PR builds the reason someone trusts what they find when they get there. Skip PR and scale paid anyway, and you get more traffic that behaves like traffic: price-sensitive, one-time, gone the moment a competitor undercuts you by $2. Plus, ads disappear when you turn them off, PR continues to build brand reputation 24/7 well after the placement appears.

Paid Acquisition Is Getting More Expensive, Not More Effective

The math on paid ads has moved against e-commerce brands for 3 years running. Average Google Ads CPCs rose 12.9% year over year, landing at $2.69 (Shopping ads specifically jumped 33.7% to $3.49). Average ecommerce search CAC now sits at $45.27, converting at 4.4%. Meta isn’t better: CPMs rose 20% to $13.48, median CPA hit $38.17, and average Shopify CAC through Facebook ads reached $58. TikTok CPMs rose 16% to $13.26 while conversion rates fell to 2.01% (Ringly, 2026).

None of that is a platform problem you optimize your way out of. iOS privacy restrictions gutted targeting precision at the same time competition for the same keywords intensified. Every DTC running the same playbook is bidding against every other DTC running the same playbook, on a shrinking pool of signal. To be clear: paid ads still work, they just buy less than they used to, and what they buy decays fast: one 2026 survey found paid conversion peaking in month 1 at 24% and falling to 8% by month 24, while earned media climbed the opposite direction, reaching 63% cumulative conversion over the same window (Baden Bower, 2026, self-reported data from 512 business owners, margin of error ±4.3%).

What Earned Media Actually Buys You

The same study found earned editorial placements delivering 4.7x the ROI of paid advertising, with an average 31% lead-to-close rate compared to 12% for paid ads and 8% for wire distribution. Trust gaps were wider still: 87% of respondents reported higher customer trust from earned coverage compared to 31% for paid ads in the same publication, and investor confidence showed a similar split, 82% versus 28% (Baden Bower, 2026). I’d treat those numbers as directional, not gospel. They’re self-reported perceptions, not audited financials. But the direction matches what I see in client accounts every year. Trust compounds. Ad spend doesn’t.

Global e-commerce is on track to hit roughly $4 trillion in 2026 (Statista, via Forbes Agency Council). At that scale, traffic alone stopped being a differentiator years ago. The brands getting this right aren’t treating PR, content, and paid as three separate budgets reporting to three separate people. They’re treating them as one system, because buyers don’t convert off a single touchpoint. They convert after a founder’s name shows up, then a product review, then a retargeting ad that finally makes sense because they already half-trust the brand.

PR First, Paid Second: What the Client Story Actually Proves

Back to that regulated e-tailer. Let’s dig deeper. Paid ads were running during the comparison period, so I can’t tell you PR alone produced an 83% jump in purchasers. What I can tell you: the brand spent close to 2 years building authority and trust through earned and owned channels before paid spend ever entered the picture. When paid finally turned on, it scaled a brand people already trusted instead of manufacturing demand from nothing. That’s why branded search behavior shifted toward the brand name and away from discount language instead of the reverse. The ads didn’t create the trust. They spent it.

That distinction matters most in regulated and competitive categories, where the advertising itself is constrained, expensive, or both. A brand that’s already built authority through earned media has something to say when paid finally opens up. A brand that hasn’t just has a bigger ad bill and the same discount-driven traffic every competitor is fighting over.

Common Questions on PR vs. Paid Ads for E-Commerce

Does PR replace paid ads for e-commerce growth?
No. PR determines what your paid budget actually buys. Skip it, and every ad dollar goes further to reach less receptive people. Build it first, and the same ad dollar converts faster, and reaches the people who already have reason to trust you. When it reaches people who don’t have reason to trust you, the authority you’ve created adds the trust missing from ads. With CAC up, the partnership between trust and scale has never been more compelling.

What’s the difference between PR and paid content or press releases?
Earned media is coverage you didn’t pay for: a journalist or publication chose to cover you. Earned media’s narrative isn’t controllable, but it carries third party credibility. Paid content isn’t as authoritative, but its narrative is controllable.

Why would branded search behavior change when PR runs before paid ads?
There are three important behaviors at play here. When people already trust a brand name, they search for the brand. When they don’t know or trust a brand, they search for a reason to trust it. If there aren’t any trust signals, then the potential customer looks for a discount. PR built before paid acquisition launches changes what people are looking for when the ads start running.

Is PR measurable for e-commerce brands?
Yes, when it’s measured against the same outcomes the business already tracks: branded search volume, direct traffic, decreased CAC, purchaser growth, and the ratio of discount-driven to trust-driven visits, not just impressions or clip counts.

Where This Goes Next

PR is not a substitute for paid acquisition, they play important and different roles. Instead, PR is a determinant of what your paid budget actually buys you. If you’re building the piece of this specific to your channel, the mechanics differ depending on whether you’re scaling as a category-defining e-commerce brand selling across multiple channels, or building a direct-to-consumer relationship with no retail intermediary at all. Both paths start in the same place: trust improves sales.
