I have also seen an increase in foot traffic at my location. Recently I had a couple from Oregon and a family from Texas find me via Google while they were in town.I highly recommend working with this group. They will be a partner in your journey and will do what it takes to help make sure you succeed.
connor st louis's Review Sourced from Google
Working with WIT Group Marketing has been one of the best business decisions I’ve made. From the first consultation, their team took the time to truly understand my goals, budget, industry, and they didn’t try to push cookie-cutter solutions. Instead, they crafted a marketing strategy that felt custom-built for my business and stage of growth.The website they designed looks sharp and performs, fast load times, and drivesconversions. Within the first two months of launching our Google Ads campaigns we started seeing a consistent uptick in qualified leads. All they while they constantly checked in with proactive suggestions to improve performance, not just reacting after the fact.I worked closely with Josh Magnum during this process and found him to be responsive, knowledgeable, and solution-oriented. Any time I had a question or requested changes whether it was tweaking the ad copy, updating the website, or routing form submissions to a different inbox he made it happen quickly and kept me in the loop.What really stood out was their accountability. They regularly shared reports, explained the data in plain English, and helped me make smarter decisions on ad spend. There were never any surprise fees, and they even suggested ways to save money on campaigns without sacrificing performance.If you’re a small business owner looking for a marketing partner that treats your business like their own who’s transparent, committed, and easy to work with, WIT Group is the team to trust.

Honestly, these guys are incredible. We run a shipping company handling cargo over to the Dominican Republic, and since partnering with Miami SEO Nerdz, our shipments have absolutely skyrocketed. Our phones are ringing constantly and the warehouse has never been this busy. It is rare to find people who actually deliver on what they promise instead of just sending over confusing charts and reports. If you want more customers and real business growth, just call them. Best investment we have made.
Julio B JB's Review Sourced from Google
I was skeptical at first because I've been burned by SEO guys before who promise the world and disappear after you pay. A friend of mine who does HVAC referred me to Miguel and honestly I'm glad he did. Within a couple months I started getting calls from people who found me on Google. Nothing crazy but enough to notice. He's straightforward, doesn't talk in circles like most of these marketing people, and actually knows the roofing business which surprised me. If you're a contractor in Miami looking for someone who gets it, give him a shot.

I applied for an SEO Specialist position and received a rejection email without any interview or initial discussion.

I appreciate the response but was disappointed not to have the opportunity to discuss my experience and skills.
Mario Inchausti's Review Sourced from Google
Perhaps there are other things they do well. We hired 829 to build our website & it was by far one of the most ridiculous experiences I’ve ever faced. Staff was incompetent & condescending for good measure. They took a year and change to deliver a site that is horrifyingly unstable. Horrible.Edit: so many 5 star reviews should make one suspicious. They gave me more attention in an effort to get me to delete this review than when we genuinely needed it. Really horrible organization and I use my experience with them often as a cautionary tale. To recap: 829 offered services they were unqualified to deliver, overcharged for those and spent more time trying to upsell and pad their team with as many warm bodies as they could charge us for. Still salty about it…
Caitlin Walker's Review Sourced from Google
Our team chose 829 after interviewing many agencies for the complete rebrand, new website build, SEO improvements, and PR guidance and strategy. Collaborating on the design of the website was surprisingly productive, we needed one or two additional rounds then was first planned and we ended up with a design we all agreed delivered on the requested notes. From brand to website, clean and fresh aesthetic. Our SEO performance was immediately light years improved and continued to grow. The team brought excellent ideas forward and worked well with our opinionated colleagues with clear vision and preferences. I personally enjoyed the 829 staff assigned to our projects and appreciated the ease of working with them through delivery and post delivery management. I would hire them again and I would recommend them without hesitation.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
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.
