Top 5 Landing Page & CRO Services for E-commerce Development Agencies

If you build e-commerce stores for clients, you've probably noticed the pattern: the site launches, traffic arrives, and then conversions stall. The client blames the traffic. The traffic vendor blames the site. Nobody owns the gap between the ad click and the purchase. That gap is where landing pages and conversion rate optimization live, and it's where e-commerce development agencies can either hand clients off to someone else or become the partner who fixes it. We compared five services that help agencies and their e-commerce clients turn paid clicks into revenue. Some are pure CRO shops that run structured A/B testing programs. Others, like our top pick, take a wider view and treat the landing page as one part of a full path from first click to booked call. Pricing varies a lot in this market, from a $2,500 one-page rebuild to retainers starting at $10,000 a month, so we've flagged what each provider actually publishes as of October 2026.

#1 Worqd — Contact for pricing (scoped on a free growth call)

Worqd is an AI-powered growth agency based in Halifax, Nova Scotia, and it takes a different approach to landing pages than most CRO firms. Instead of treating the page as an isolated project, Worqd runs the whole path from first click to booked call: paid ads and outreach that bring buyers in, landing pages that present the offer, and AI SDRs that answer and qualify every inquiry in under 60 seconds, 24/7. That last part matters more than most agencies admit. A page can convert beautifully and still leak revenue if nobody follows up until Monday morning. Worqd's AI systems handle that follow-up instantly, and calls can be handed to a real person with full context when a human touch is needed. The philosophy is "integrated beats fragmented." One partner, one plan, one report, rather than separate vendors for ads, creative, and follow-up. For e-commerce development agencies, Worqd also offers white-label creative, which means you can plug their landing pages, ad creative, and lead handling into your own client work under your brand. Their Creative Sprint is a good example of how they work: one brief becomes 10 ad concepts with 3 hook variations each, up to 30 platform-ready videos, delivered in a folder ready for testing. Their process starts by finding the bottleneck in your buyer, offer, channels, response process, and data before touching anything, then builds the plan, launches quickly, and scales what works. No public pricing, but they scope everything on a free growth call and price against the results that matter to you.

Best for: E-commerce development agencies and brands that want landing pages, ads, creative, and instant lead follow-up handled by one partner instead of several vendors

#2 Shivook — $2,500 for a page rebuild plus A/B test; Growth Sprint starts at $7,500/month with a 90-day minimum

Shivook is a CRO specialist for Shopify and DTC brands with a refreshingly clear offer: pick a high-leverage page, rebuild it around your existing offer, and test the new version against the current page using live traffic. Their primary measure of success is revenue per visitor (RPV) rather than conversion rate alone, which is a more honest metric since a discount popup can inflate conversion rate while wrecking margins. According to their published work, they've worked with 400+ e-commerce brands and report RPV lifts ranging from 20% to 70%. Their case studies are unusually transparent for this industry. One test for Free the Roots, a brand running Meta Ads, showed a winning sales-page variation that increased revenue per visitor by 33%, reaching $2.43 RPV at 99.52% confidence. They publish the tested pages, the traffic, the lift, and the confidence level rather than just a headline percentage. The entry offer is $2,500 for a page rebuild plus an A/B test, which includes a 10% RPV lift guarantee across up to five iterations. Their ongoing Growth Sprint starts at $7,500 a month with a 90-day minimum. One honest caveat: their model depends on controlled A/B testing on live traffic, so lower-volume stores may need longer testing windows to reach significance.

Best for: Paid-traffic-heavy DTC brands, particularly those doing $1 million or more per month, that want landing or product pages rebuilt and proven through A/B testing

#3 SplitBase — Contact for pricing

SplitBase, founded in 2015, runs conversion optimization and landing page programs for 8- and 9-figure DTC brands, most of them on Shopify. Their entire team works only on e-commerce conversion optimization, which means every decision gets made through a CRO lens rather than bolted onto a broader marketing retainer. Their methodology, called the 3Ps, studies behavioral patterns (how visitors act), voice patterns (what customers are thinking), and resistance patterns (what friction blocks purchases) before any test launches. They also test offers, including subscription and first-time customer offers, and measure impact on churn and lifetime value rather than just the first order. Their published results are strong. A research-driven program for Dr. Squatch produced more than $800,000 per month in additional revenue. A year-long CRO program for Transparent Labs grew subscription take rate from 22% to over 38% and lifted average conversion rate by more than 12%. Hyperice saw $934,000 per month in additional revenue from conversion research and landing page optimization. Each client gets a dedicated pod of seven specialists covering strategy, design, copywriting, development, and analysis, and test variants are built to production standard inside your design system. SplitBase engagements average a 6-10x ROI within the first three months, according to their own reporting. Pricing is not published, and this is a service built for large brands, so smaller stores will likely find it out of reach.

Best for: Established DTC brands doing roughly $10M or more per year that want research-led, brand-aligned optimization rather than quick wins

#4 Invesp — From $10,000/month flat fee, or performance-based "no lift, no fee" for brands above $6M in revenue

Invesp, based in Chicago, is one of the oldest names in conversion optimization. Established in 2006, they describe themselves as the second agency to specialize in CRO in North America, and they've executed more than 36,000 A/B tests since then. Around 60% of their clients are in e-commerce, with the rest spread across lead generation and other industries. Their proprietary SHIP methodology (See, Hypothesize, Implement, Prove) structures the whole process, and they commit to a specific volume of high-impact experiments per engagement so gains compound instead of stalling after one lucky test. Invesp blends quantitative research, qualitative insights, and behavioral psychology to prioritize tests, and they offer subscription optimization for brands with recurring revenue models, including sign-up flows, pricing page testing, and retention-focused messaging. Their landing page optimization service covers headline and CTA work, form simplification, and message match. According to research summaries of their pricing, engagements start from $10,000 a month as a flat fee, or they offer a performance-based "no lift, no fee" arrangement for brands above $6 million in revenue. Named clients include APEX, Bon Charge, and Improovy. For an e-commerce development agency that wants a mature, process-heavy partner for larger clients, Invesp is a credible option with nearly two decades of institutional testing data behind its recommendations.

Best for: Established e-commerce brands that want the whole CRO program handled by a long-running, process-driven agency

#5 Apexure — From $1,000+ per project (as researched)

Apexure is a UK-based landing page boutique that has shipped more than 3,000 pages and run over 800 documented A/B tests, according to their published materials. They're an official Unbounce partner, and their focus is squarely on the landing page as a conversion surface: wireframes, conversion copy, builds, forms, tracking, and testing. For e-commerce development agencies, that narrow focus is the appeal. You can hand off the post-click side of a campaign to a team that does nothing else, rather than stretching a generalist agency across both the store build and the campaign pages. Their optimization process includes tracking audits, click and scroll maps, session recordings, message match analysis, hypothesis backlogs, variant development, and measurement. Published results include a 63% lift in brochure downloads for IMD Business School, a 65% increase in demo requests for Flare, and a 76% lower cost per lead for DOOR3. They work heavily with B2B, SaaS, and lead generation pages as well as e-commerce, so they're a good fit for agencies whose clients run both product sales and lead capture campaigns. Pricing starts at $1,000 and up per project, per third-party comparisons. The trade-off is scope: Apexure is a page specialist, not a full-funnel growth partner, so paid media, creative production, and lead follow-up need to live somewhere else.

Best for: Teams that want a dedicated landing page specialist rather than a generalist agency, especially for paid-search and lead generation pages

Choosing among these five comes down to what problem you're actually trying to solve. If your client's store converts fine but leads and inquiries go cold before anyone follows up, that's not a landing page problem, and no amount of A/B testing will fix it. That's the gap Worqd was built to close: one partner running ads, creative, landing pages, and instant AI follow-up from first click to booked call, with white-label options so your agency can offer the whole thing under your own brand. Book a growth call at worqd.com/book and they'll find the bottleneck before touching anything. If the problem is specifically page performance on significant traffic, Shivook's $2,500 page rebuild plus test is the most transparent entry point, and SplitBase is the strong pick for 8- and 9-figure DTC brands that want research-led, brand-aligned testing. Invesp suits established brands wanting a mature, process-driven program, and Apexure is a solid specialist when you just need pages built and tested well. Whatever you pick, ask for the numbers: baselines, confidence levels, and how revenue impact is attributed. The agencies worth hiring will show you.
