A/B Testing & Experimentation

The difference between a funnel that converts and one that doesn’t is usually a handful of decisions that nobody tested. We run systematic A/B testing and experimentation programs that replace guesswork with data — and turn incremental improvements into compounding growth.

Most marketing decisions are opinions. A/B testing turns them into facts.

Everyone on the team has a view on which headline is better, which CTA will convert more, whether the form should have three fields or six.

The problem with deciding by committee is that the highest-paid person’s opinion wins — and that person’s instincts are right about as often as anyone else’s, which is not as often as they think.

A/B testing removes the opinion from the equation. You run both versions. You measure which one produces more of what you want. You scale the winner and retire the loser. Then you do it again.

That’s the entire discipline — and when it’s done systematically across every stage of the funnel, the compounding effect on conversion rates and revenue is significant.

How we run A/B testing and experimentation

  • Testing strategy — identifying which variables to test first based on their potential revenue impact, starting with the highest-leverage decisions
  • Hypothesis development — defining what we're testing, why we believe one variant will outperform the other, and what result would constitute a meaningful improvement
  • Test build — creating the variants correctly so the test is clean and the results are trustworthy
  • Statistical validity — running tests long enough and with enough traffic to produce results you can act on with confidence
  • Results analysis — interpreting what the data actually means, including cases where the result is inconclusive or counterintuitive
  • Scaling winners — implementing winning variants across the full funnel and using the insight to inform the next test
  • Ongoing testing roadmap — maintaining a prioritized pipeline of tests so experimentation is continuous, not occasional

What we test

  • Headlines and value propositions on landing pages and homepages
  • Ad copy and creative across Google and Meta campaigns
  • CTA copy, placement, and design
  • Form length and field order
  • Email subject lines and preview text
  • Email body copy and offer structure
  • Landing page layout and content hierarchy
  • Offer framing and pricing presentation
  • Follow-up sequence timing and messaging

Who this is for

Businesses running paid media that want to improve conversion rates without increasing spend. Marketing teams that have strong intuitions about what will work but want data to validate before rolling out changes broadly.

eCommerce brands optimizing product pages, checkout flows, and email sequences. Professional service firms testing landing pages and lead capture forms. Any organization that wants marketing decisions driven by evidence rather than preference.

Experimentation as a competitive advantage

The businesses that test consistently outperform the ones that don’t — not because any single test produces a dramatic breakthrough, but because the cumulative effect of dozens of small improvements compounds into a meaningfully better conversion rate across the entire funnel. That’s the value we deliver through systematic experimentation.

We serve businesses across Philadelphia, Bucks County, and nationally.

Frequently Asked Questions

What does Weather Vane do?
Weather Vane Digital is a sales and marketing agency based in Doylestown, PA. We build end-to-end lead generation systems, manage paid media, design and develop websites, and run content and email marketing programs for professional service firms, healthcare organizations, senior living communities, nonprofits, and eCommerce brands. We don’t just run campaigns — we build the systems that generate consistent, predictable revenue.
Weather Vane Digital is headquartered in Doylestown, Pennsylvania — in the heart of Bucks County. We serve clients locally across the Philadelphia metro area and remotely across the United States.
We serve businesses across Bucks County, Montgomery County, Philadelphia, Chester County, Delaware County, South Jersey, and the greater Delaware Valley. We also work with clients nationwide and have supported brands across the United States, Canada, and internationally.
Yes. While we’re rooted in the Philadelphia region, the majority of our work is done remotely and we actively serve clients across the country. If you have a strong product or service and need a marketing system that generates leads, we can help regardless of where you’re located
A sales and marketing agency builds the systems that bring in new customers consistently — so your growth doesn’t depend on referrals, word of mouth, or hoping the phone rings. We identify where your pipeline is leaking, build the funnel that fills it, and run the campaigns that keep it full. The result is more qualified leads, shorter sales cycles, and more predictable revenue.
Weather Vane Digital specializes in law firms, business insurance agencies, healthcare groups, senior living communities, nonprofits, and eCommerce brands. We go deep in these verticals rather than wide across every industry — which means we already understand your buyer, your competition, and what works in your market before we start.
Yes — these are three of our core verticals. We have active case studies and proven results across personal injury law, estate planning, family law, independent insurance agencies, physical therapy groups, behavioral health networks, home health agencies, and more. We understand the compliance considerations, the buyer psychology, and the competitive landscape in each of these categories.
Yes. Senior living and nonprofits are two of our strongest verticals. We’ve worked with independent communities, regional operators, and national senior living brands on occupancy campaigns, local SEO, and family nurture systems. On the nonprofit side, we’ve built donor acquisition, program enrollment, and volunteer recruitment campaigns for organizations across the Philadelphia region and beyond
Yes. We work with DTC eCommerce brands on paid media, email lifecycle marketing, creative production, SEO, and Shopify development. Whether you’re scaling acquisition or fixing retention, we build the system that moves the needle on revenue — not just traffic.

Most agencies sell you a service — SEO, ads, social media — and hand you a report at the end of the month. Weather Vane Digital sells you an outcome. We build the full system — from first touch to closed deal — and we take ownership of the results, not just the deliverables. We also specialize in specific industries, which means we’re not learning your market on your dollar.

We offer lead generation, paid media management (Google Ads and Meta Ads), funnel strategy and execution, website design and development, Shopify development, WordPress development, brand strategy, content marketing, social media management, email marketing, marketing automation, SEO, conversion rate optimization, and fractional CMO services. Full list available on our services page.
Our engagements typically start at $2,000 per month for focused services and scale based on scope, channels, and the level of involvement required. Website projects are priced separately based on scope. We charge $125 per hour for project-based work and offer monthly retainer pricing for ongoing services. We’re transparent about pricing from the first conversation — no surprise fees, no bloated retainers.
It depends on the channel. Paid media campaigns typically show measurable results within the first 30 to 60 days. SEO and content marketing are longer-term plays — you’ll start seeing movement within 90 days and meaningful results within 6 months. Funnel and email work compounds over time. We set clear expectations in the first meeting so you always know what to expect and when.
A sales funnel is the system that takes a stranger and turns them into a paying customer — through a series of intentional steps that educate, build trust, and move them toward a decision. If your business depends on more than one touchpoint to close a sale, you need a funnel. Without one, leads fall through the cracks, follow-up is inconsistent, and revenue is unpredictable. With one, your pipeline runs whether or not you’re actively selling.
Yes. Many of our clients are small to mid-size businesses doing between $500K and $15M in annual revenue. We build systems that are appropriately sized for where you are right now and designed to scale as you grow. You don’t need a massive budget to work with Weather Vane Digital — you need a real problem worth solving and the commitment to build the system that solves it.
If you can’t answer these three questions — where does each lead come from, what does each lead cost, and what does each lead convert at — your marketing is not working as well as it should be. We build tracking and reporting systems into every engagement so you always have clear, accurate answers to all three. No vanity metrics. No guessing. Just the numbers that actually matter.
Lead generation is the process of attracting and capturing potential customers for your business. It works by identifying who your ideal customer is, finding where they spend their time online, putting the right message in front of them at the right moment, and giving them a clear next step — whether that’s requesting a quote, booking a call, or filling out a form. Weather Vane Digital builds lead generation systems that do this consistently and at scale, so your pipeline is never dependent on referrals or word of mouth alone.
The first step is a free consultation call. We’ll ask about your business, your current marketing, and where you’re losing leads or revenue.
