      Web Development Review from Kate Strollo

      I cannot speak highly enough of the team over at Gapstow. Shawn goes above and beyond to ensure value for his clients, as does his team of project managers and web developers. Pricing and timelines were always crystal clear, and the team overall is responsible and incredibly easy to work with. This is the first and only development agency I've truly ever felt comfortable working with. I would recommend them to anyone and would absolutely work with them again in the future.

      Shopify Plus eCommerce Review from Jessica Grant

      Bighorn has been an exceptional partner to our organization here at Sports Basement. They supported us through multiple legal and regulatory accessibility matters with a steady, knowledgeable approach, translating complex requirements into clear, actionable guidance. Throughout these engagements, their team demonstrated a strong understanding of both the legal landscape and the practical realities of building and maintaining accessible digital experiences, which gave us confidence at every step.What truly distinguishes them is that their work goes well beyond compliance. In addition to helping us identify and prioritize accessibility issues, they invested time in educating our teams on how to design and develop accessibility into our site from the start. Their recommendations are thoughtful, pragmatic, and focused on real user impact, enabling us to move from a reactive posture to a more proactive, sustainable accessibility practice.Most importantly, they operate as true partners rather than transactional consultants. Their work is clearly driven by a genuine commitment to making the web usable by all, not simply meeting minimum standards or checking a box. We would strongly recommend them to any organization looking for a strategic accessibility partner who combines expertise, integrity, and a long-term perspective.

      Web Design Review from Alex Choi

      We brought this agency in as a consultant during a major redesign initiative, and their impact was immediate.They provided clear best-practice guidance across UX, conversion strategy, and design systems helping us think beyond aesthetics and focus on structure, clarity, and performance. What stood out most was their ability to balance strategic insight with practical execution. They didn't just point out what could be improved; they offered thoughtful, actionable solutions.Throughout the process, they were collaborative, responsive, and consistently available to support our internal team. Whether it was refining layout hierarchy, improving user flows, or pressure-testing creative direction, they were a steady partner from start to finish.If you're looking for a team that combines strong design instincts with conversion-minded thinking and a consultative approach, Id highly recommend them.

      We had a fantastic experience partnering with Glide to redesign our website. From the very beginning, their team showed a genuine interest in understanding the mission and work of the Center for Child Protection. This thoughtful approach allowed them to tailor the site better to meet the needs of our diverse audiences.Their expertise in web design was evident throughout the process, and they worked closely with us to ensure the final product was impactful and user-friendly.

      Ray Watts's Review Sourced from Google

      We hired Laughing Samurai to do a refresh of an initial website they built for us a few years prior as well a proposal template design that we could use as a sales tool with new clients. We were looking to improve our overall sales funnel, improve look/feel of the website and qualify new leads with improved copy, visuals and call to actions.We started the project off with a kickoff meeting to understand all of the goals and deliverables in entirety. Once we had the website framework decided, Laughing Samurai moved into website design, copywriting assistance and website development. While the website was being developed, they helped consult on our proposal design and process and create a templated document and design for our sales team to use moving forward that reflected the look of the new website.As for the website and proposal process, we couldn’t be happier right now. The website is pulling in some attention, but most importantly, is a professional site for visitors that have been referred to us to see who they’ll be talking to. The proposals are great, and have saved a ton of time.

Conversion Rate Optimization Services FAQs

What services do conversion optimization agencies in the US provide?

They focus on improving how effectively a website turns visitors into customers. Core services include: 

  • Comprehensive website and funnel audits: Identify friction, drop-offs, and performance issues. Faster pages convert better, and one-second loads can produce up to three times more conversions than slower pages. 
  • Qualitative and quantitative research: Combine analytics and user feedback to understand intent, barriers, and pain points. 
  • User behavior analysis: Use heatmaps, click paths, and session recordings to uncover confusion or hesitation. 
  • Customer journey mapping: Redesign key steps to reduce friction and improve flow through the funnel.
  • Hypothesis development: Create evidence-based test ideas grounded in research and auditing findings. 
  • A/B and multivariate testing: Run experiments to validate high-performing variations. Strong A/B tests can lift landing page conversions by roughly 30%.  
  • Landing page and checkout optimization: Streamline product pages, forms, and checkout steps. Roughly 22% of shoppers abandon carts when the process is too long or complicated. 
  • Content and design optimization: Improve messaging, layout, and UX to guide users smoothly. A seamless experience can increase conversions by up to 200%. 

How much does conversion optimization cost in the US?

Hourly rates for conversion optimization in the US start from $55 and can reach up to $300. For per-project fees, the rates go from $5,000 to $100,000+, depending on scope, channel complexity, and program length. 

Most US-based conversion optimization companies fall into three clear cost tiers: 

  • Hourly Rates 
    • $55/hr for smaller Shopify or WordPress optimization tasks 
    • $100-$135/hr for standard CRO, UX optimization, and Shopify Plus work 
    • $300/hr for enterprise PPC or multi-channel conversion programs 

  • Project-Based Pricing 
    • Under $5,000 for small, targeted CRO updates such as landing page fixes, SEO-driven conversion improvements, or short PPC experiments
    • $5,000-$20,000 for 2-3 month optimization cycles covering audits, UX updates, and basic testing 
    • $20,000-$100,000 for full CRO programs for 3-6 months including research, journey mapping, A/B testing, and funnel optimization
    • $250,000-$1 million for enterprise, multi-channel CRO engagements spanning PPC, DTC, or large-scale eCommerce platforms over 12-36 months

When can clients expect ROI from a conversion optimization project?

The return on investment (ROI) typically follows a predictable timeline: 

  • 4-6 weeks: Early gains from fixing clear usability or funnel issues 
  • 3-6 months: Most clients see the strongest, measurable ROI within this window 
  • Ongoing: Incremental improvements as validated tests replace assumptions 

What is the typical timeline for a full optimization cycle, from initial audit to testing and rollout?

A full conversion optimization cycle typically runs 8 to 12 weeks and follows a structured sequence: 

  • 1-2 weeks of research and auditing 
  • Hypothesis development and test design 
  • A/B testing over several weeks to gather statistically reliable data 
  • Implementation of winning variations across the site 

Early improvements may appear within 30 to 45 days, but 2 to 3 months is the usual timeline to move from audit findings to fully implemented, data-backed changes. 

How often do they review performance data and adjust during an active campaign?

CRO teams follow a set review cadence during active campaigns: 

  • Weekly metric checks to identify early trends or issues 
  • Monthlydeep reviews to adjust strategy 
  • Post-test analysis immediately after each A/B test concludes 
  • Mid-test changes only when a clear issue is detected 
  • Quarterly audits to refine the roadmap and introduce new test ideas 

Which business types do conversion optimization companies most often support?

These types of agencies work with companies of all sizes. DesignRush data shows: 

  • ~50% of clients are small businesses (<50 employees) 
  • ~20-30% are mid-market (50–249 employees) 
  • ~10% are large enterprises
