eCommerce Development Review from Undisclosed
We have been working with First Pier for almost 10 years now, beginning with the launch of our women’s boutique E-Commerce business. First Pier has been responsible for our e-commerce store design, web development, e-commerce SEO, digital strategy, online marketing campaigns and beyond ever since. As a already successful brick and mortar retailer, we saw an opportunity to reach beyond our existing customer bases in Portland, Maine & Portsmouth, New Hampshire by creating an online shopping experience accessible 24/7 and nationwide. First Pier has helped us turn that vision into reality by taking us from no online store and zero sales to a dependable thriving new channel for our business that continues to grow. Our experience with Shopify started when First Pier migrated our site from Magento to a Shopify website. Since First Pier is a designated Shopify Expert, we knew we could trust them with the daunting task of moving all of our products, accounts, and customer history to our new Shopify site. They made the transition to a new e-commerce system painless by ensuring our hands were held along the way, we were thoroughly trained, and none of the SEO ranking keywords were lost. We continue to work with First Pier on expanding our use of Google Shopping SEO and will be implementing Shopify’s Point of Sale in the coming year as part of a continued effort to deliver a unified customer experience at our stores. As a small women’s boutique based in Maine, we are now able to deliver our customer experience to tourist and seasonal customers where they are year round. We would recommend First Pier to anyone looking to build or update a Shopify store.
Shopify Review from Undisclosed
First Pier has been so helpful with the transition to shopify. After initially setting it up they provided us with great documentation on how to use the site and they've continued to support us through any issues that arise.
Shopify Review from Undisclosed
First Pier helped us move, update, and launch our online business on Shopify. As a high-traffic bakery, it was important to us that customers buying from around the country were able to view the quality of our products, feel the vibe of our Portland and South Portland shops, and trust that their order would be as special as a visit to our Maine bakery. First Pier delivered mouth-watering e-commerce product photography, an easy-to-use site, and supported us every step of the way. Our shoppable site is now optimized, accurately reflects our brand, and has poised us for growth.

They never pressured us into any 'extras' or oversold anything. They listened to what we wanted and delivered exactly that. I would recommend 1 At Bat Media for any of your website or digital media solutions.

Damian's Review Sourced from Google
We’ve worked with IMP Marketing for our hair care brand for around two years, mostly on ads and email marketing. They really took the time to understand our products and customers, which made their suggestions feel much more useful.They helped us improve our campaigns, organize our email flows better, and make our marketing feel more consistent overall. I also liked that they cared about the visuals, which is important for a beauty brand, but still kept the focus on results.The team was responsive, clear, and easy to talk to whenever we had feedback. Overall, we’re really happy with their support.

A conversion rate optimization (CRO) agency is a marketing agency that specializes in improving a website's ability to turn visitors into customers or leads. It focuses on increasing conversion rates for its clients.
A CRO agency helps increase website conversions by analyzing user behavior and adjusting the site to increase the percentage of visitors who complete a desired action, such as purchasing or signing up for a newsletter.
CRO services are most valuable for eCommerce stores, SaaS platforms, financial services, and subscription-based businesses, where even the smallest conversion lifts directly increase revenue.
They also benefit B2B companies with high-value leads, such as legal, healthcare, and enterprise tech, where optimizing forms, landing pages, and funnels boosts qualified lead generation and lowers acquisition costs.
Top-rated CRO agencies on DesignRush in 2025 are:
Conversion rate optimization companies offer services including:
Specialized CRO services:
Depending on the pricing model and the type of project, a CRO agency may charge from $2,000 to $30,000 per month.
Most businesses see initial conversion rate improvements within 4-6 weeks once testing and quick wins are implemented. Deeper, more sustained gains usually appear after 3-6 months as multiple A/B tests, UX changes, and optimization cycles compound.
Look for a CRO agency with proven case studies, data-driven methodology, and expertise in A/B testing, analytics, and UX/UI design.
Ensure they provide transparent reporting, industry experience, and a clear testing roadmap tailored to your goals. The best agencies also integrate seamlessly with your marketing stack and emphasize measurable ROI.
A CRO agency might not be the best fit if it displays the following warning signs:
Before signing a contract with a CRO agency, ask them the following questions:
Conversion rate optimization focuses specifically on turning existing traffic into leads or sales through testing, analytics, and funnel improvements. Digital marketing, on the other hand, drives traffic via channels like SEO, PPC, and social, while UX services improve overall usability and design.
CRO bridges both by using data to maximize conversions from the traffic and experiences those efforts create.
Top CRO agencies use A/B and multivariate testing tools like Optimizely, VWO, and AB Tasty, together with behavior analytics platforms such as Hotjar, FullStory, Mixpanel, and Heap to track user actions. They also rely on feedback tools for surveys and usability testing, plus onboarding optimization tools like Userpilot to refine customer journeys.
For experimentation, conversion rate optimization agencies rely on frameworks such as ICE, PIE, and PXL to prioritize tests, along with models like the Lift Framework and JTBD for structured hypothesis building.
Our goal is to provide accurate and useful information to both businesses and agencies, which is why we partnered with Mike Melen, co-founder of digital marketing agency SmartSites. He shared best practices for optimizing user journeys and reducing friction in the conversion process.
As a young entrepreneur, Mike Melen sold his first company at 19 years old. He has since led SmartSites, which has garnered eight Inc. 5000 recognitions and more than 1,000 5-star reviews. Melen’s work in the marketing field has also received honorable mentions from Forbes, AdWeek, and Inc. Magazine.
