EcoFlow’s $15K SEM Win: 400% ROAS in 2026

Understanding search engine marketing (SEM) is no longer optional for businesses aiming to thrive online. It’s the engine that drives visibility, leads, and ultimately, revenue. But how do you actually build a campaign that delivers tangible results, moving beyond just clicks to meaningful conversions? We’re going to dissect a recent campaign that did just that.

I’ve spent years in the trenches of digital advertising, and one thing I’ve learned is that theory only gets you so far. You need to see how it plays out in the real world, with real numbers and real challenges. That’s why I want to walk you through a recent campaign we executed for “EcoFlow Solutions,” a fictional B2B provider of sustainable energy consulting services based right here in Atlanta, Georgia. Their target market was commercial property managers and facilities directors within the Southeast region, specifically looking for energy efficiency audits and solar integration feasibility studies. They wanted to generate qualified leads that their sales team could then convert into proposals.

Campaign Teardown: EcoFlow Solutions’ Sustainable Energy Lead Gen

Our goal for EcoFlow was clear: drive high-quality leads for their specialized B2B services. We knew this wasn’t about mass appeal; it was about precision. We set out to prove that even with a relatively modest budget, strategic SEM could deliver a significant return.

Initial Strategy & Budget Allocation

We designed a 90-day SEM campaign with a total budget of $15,000. This was divided across several key areas:

• Google Search Ads (Branded & Non-Branded Keywords): 60% ($9,000)
• Dynamic Search Ads (DSAs): 15% ($2,250)
• Google Display Network (GDN) Retargeting: 15% ($2,250)
• Landing Page Optimization & A/B Testing Tools: 10% ($1,500)

My philosophy is always to start with the highest-intent channels. For B2B, that’s almost always Google Search. People are actively looking for solutions, and we needed to be there. DSAs were included to catch long-tail, unexpected queries that we might miss with traditional keyword research, a technique I’ve seen pay dividends for clients in niche industries.

Creative Approach & Messaging

For search ads, our copy focused on immediate pain points and solutions. Headlines like “Reduce Energy Costs by 30%,” “Expert Energy Audits Atlanta,” and “Solar Feasibility Studies for Commercial Properties” were paired with descriptions highlighting benefits: “Unlock significant savings. Certified consultants. Request a free consultation.” We used call extensions and structured snippets to showcase our services and contact info directly in the ad.

The retargeting ads on GDN were designed with a slightly different angle. For those who had visited the site but hadn’t converted, we used testimonials and case study snippets. “See how XYZ Corp saved $100k annually – EcoFlow can help you too!” This softer sell aimed to nurture prospects further down the funnel.

Targeting & Audience Segmentation

This is where we really drilled down. For our Google Search campaigns, we used a combination of exact match and phrase match keywords related to “commercial energy audit,” “industrial solar panel installation,” “energy efficiency consulting,” and even geo-modified terms like “Atlanta sustainable energy solutions.” We layered this with geographical targeting, focusing on a 100-mile radius around Atlanta, covering key business hubs like Midtown, Buckhead, and the Cumberland/Galleria area, extending into parts of North Georgia and even Alabama. We also applied audience targeting for B2B segments, looking at “business services” and “facilities management” interests where available in Google Ads, though primary targeting remained keyword-driven.

For retargeting, we created custom audiences:

• Website Visitors (30 days): Anyone who hit the site but didn’t fill out a form.
• Specific Service Page Visitors: Those who viewed the “Solar Integration” or “Energy Audit” pages.

I always tell my team, don’t just retarget everyone. Segment your retargeting audiences based on their engagement. Someone who spent five minutes on a specific service page is far more valuable than someone who bounced immediately from the homepage.

What Worked

The campaign, overall, was a resounding success. Here are the key metrics and what drove them:

Stat Card: Overall Campaign Performance (90 Days)

• Budget: $15,000
• Impressions: 1,250,000
• Clicks: 28,000
• Click-Through Rate (CTR): 2.24%
• Conversions (Qualified Leads): 1,120
• Cost Per Lead (CPL): $13.39
• Return on Ad Spend (ROAS): 350% (based on estimated lead value)

Our CPL of $13.39 was well below EcoFlow’s target of $25. This was largely due to the hyper-focused targeting and continuous optimization. The Dynamic Search Ads were a pleasant surprise. They accounted for nearly 20% of our total conversions in the first month, catching queries like “building energy performance optimization Atlanta” and “commercial property green certification consultant” that we hadn’t explicitly keyworded. This confirmed my long-held belief that DSAs are invaluable for uncovering new, high-intent search terms.

The retargeting campaign was also incredibly efficient. While it only accounted for 15% of the budget, it delivered a ROAS of over 400%, converting visitors who were already familiar with EcoFlow Solutions. The custom audiences and tailored messaging clearly resonated.

What Didn’t Work (Initially) & Optimization Steps

It wasn’t all smooth sailing, of course. No campaign ever is. In the first two weeks, we noticed a higher-than-expected bounce rate on one of our landing pages – the one for “Energy Audit Services.” We also saw some irrelevant impressions coming through for terms like “home energy audit” and “free energy audit government.”

Comparison Table: Landing Page Performance (First 2 Weeks vs. Post-Optimization)

Optimization Step 1: Landing Page Refinement. We immediately ran A/B tests on the “Energy Audit” landing page. Our initial page was a bit too text-heavy. We introduced more visual elements, clearer calls-to-action (CTAs) above the fold, and added a short, compelling video explaining the audit process. We also condensed the lead form, removing two optional fields that we realized weren’t critical for initial qualification. According to a HubSpot report, simplifying forms can increase conversion rates by up to 120%, and we certainly saw a significant improvement here.

Optimization Step 2: Negative Keyword Implementation. The irrelevant impressions were costing us. We aggressively added negative keywords like “home,” “residential,” “free,” “DIY,” and specific competitor names to our campaigns. We reviewed the search term report daily for the first month, identifying new negative keywords to add. This reduced our irrelevant impressions by about 30% within the first two weeks of implementation, saving valuable budget.

Optimization Step 3: Bid Adjustments & Ad Scheduling. We noticed that conversions were significantly higher during standard business hours (9 AM – 5 PM, Monday – Friday). We implemented bid adjustments, increasing bids by 20% during these peak times and decreasing them by 50% outside of them. We also adjusted bids for specific geographic areas that showed higher conversion rates, such as businesses located within a 10-mile radius of the Atlanta Perimeter Center, where many of EcoFlow’s target clients were headquartered.

I remember a client last year, a manufacturing equipment supplier, who insisted on running ads 24/7. Their logic was “someone might be searching late at night.” While true, the conversion rate outside of business hours was abysmal, and their sales team wasn’t available to follow up. We implemented ad scheduling, and their CPL dropped by 18% almost overnight. It’s about smart spend, not just maximum spend.
