Reading Time: ~12 minutes | By Barn2 Plugins
Discover how Katie Keith built a $1.8M WordPress plugin portfolio with 20 products serving 90,000+ websites. This guide covers her proven multi-product strategy, organic SEO tactics, and cross-selling playbook, all without a dollar of paid advertising.
Why the Multi-Product Approach Is Smarter Than You Think.
Most startup advice sounds like a broken record: pick one product, go deep, ignore everything else. And for many businesses, that’s the right call. But it’s not the only path, and for Katie Keith, it wasn’t even the best one.
Katie is the founder of Barn2 Plugins, a fully remote company that has quietly grown into something remarkable: 20 software products, $1.8 million in annual recurring revenue, and over 90,000 active installations across websites worldwide, all without venture capital, paid ads, or a single office.
The numbers tell a compelling story:
- $9.8 million in lifetime sales across the portfolio
- 90,000+ active plugin installations worldwide
- $150,000 average monthly recurring revenue
- Consistent profitability with zero outside funding
- A lean remote team managing the entire operation
This isn’t a story about luck or viral moments. Katie’s success is grounded in organic SEO, strategic cross-selling, and solving real problems for WordPress users. If you’re a developer, founder, or indie entrepreneur thinking about a multi-product business, this guide breaks down exactly how she built it, and how you can too.
The Origin Story: One Problem, One Plugin
Katie didn’t sit down one day and plan a 20-product empire. Her journey started the way most good businesses do, by noticing a gap and deciding to fill it.
Product 1: WooCommerce Protected Categories
Before writing a single line of code, Katie did her homework. She spent time reading through the WooCommerce ideas forum, a goldmine of real user frustrations, and started looking for a pattern. What did people keep asking for that nobody had built?
Her research process was methodical:
- Studied the WooCommerce ideas forum to surface frequently requested features
- Analyzed existing plugins to map gaps in functionality
- Validated demand by checking search volume and forum activity
- Identified a high-demand feature with no real solution in the marketplace
The result was a plugin that let WooCommerce store owners create password-protected or members-only product categories. Hundreds of users had asked for it. Nobody had built it yet. Katie built it.
Key Takeaway: Don’t guess at product ideas. Go where your target customers are already asking for help, then give it to them.
Product 2: "Post Table Pro" The Accidental Hit
Her second product didn’t come from forum research. It came from client work.
While building a custom solution for a client, a way to display WordPress posts in searchable, filterable tables, Katie realized this wasn’t a one-off need. Thousands of WordPress sites had exactly this problem. She polished the code, packaged it as Post Table Pro, and it became one of her best-performing plugins.
Key Takeaway: Pay attention to what your clients keep asking for. Repeated requests are a signal, and your next product might already be half-built.
The Portfolio Effect: Why 20 Products Beat One Big Bet
Managing 20 products sounds exhausting. Most founders assume it would be 20 times the work. Katie’s experience says otherwise.
How Portfolio Revenue Compounds
1. Revenue Stability Through Diversification
When one plugin has a slow month, 19 others keep the revenue flowing. Algorithm changes, market shifts, and seasonal dips that would kneecap a single-product business become minor inconveniences in a diversified portfolio.
2. Customer Lifetime Value Multiplication
A customer who buys one $79 plugin might buy three or four more over time. Katie’s data shows portfolio customers are worth two to four times more than single-product buyers. Cross-selling also keeps customers engaged longer, reducing churn in the process.
3. Shared Infrastructure Lowers Costs
One support team serves all 20 products. One marketing website drives traffic to the entire portfolio. Development frameworks and code libraries get reused across products. The marginal cost of adding a new product keeps dropping as the infrastructure matures.
4. Built-In Launch Advantage
When Katie launches a new plugin today, she’s announcing it to tens of thousands of existing customers. Her email list, SEO domain authority, and social proof are already in place. New products don’t start from zero anymore.
The Growth Timeline
| Year | Revenue | What is the difference |
|---|---|---|
| Year 1 | $50k | 1 product — learning the market |
| Year 2 & 3 | $180k | 3 products — existing customers bought new releases |
| Year 4 | $400k | 6 products — cross-selling effect kicking in |
| Year 5 | $950k | 12 products — portfolio compounding at scale |
| Now | $1.8M | 20 products — full portfolio flywheel in motion |
Finding Product Ideas: 3 Sources That Never Run Dry
After 20 products, Katie has refined her ideation process down to three reliable sources. None of them requires a flash of genius, they’re all about paying attention.
Source 1: Community Forums and Feature Requests
Where to look:
- WooCommerce Ideas Board, the official feature request forum
- org Support Forums, look for recurring questions with no clean answers
- Reddit communities: r/WordPress, r/WooCommerce, r/Shopify
- Facebook Groups for WordPress developers and site owners
What signals a genuine opportunity:
- Requests with 50 or more upvotes or comments
- People solving problems with messy code snippets (means no plugin exists yet)
- Features that premium themes advertise but consistently under-deliver
Real Example: WooCommerce Protected Categories came directly from a forum request that had 200+ upvotes. There was no plugin for it. Katie built one.
Source 2: Client Projects
Client work is underrated as a product incubator. When you’re building custom features for paying clients, you’re also getting paid to validate product ideas.
The process Katie recommends:
- Take on selective client work in your ecosystem (WordPress, Shopify, etc.)
- When building custom features, ask: ‘Would 100+ other sites need exactly this?’
- If yes, generalize the solution and package it as a plugin
- Use the original client as a case study for marketing
Real Example: Post Table Pro generated over $800K in revenue from what started as a single client project. Charge the client for the custom work, retain the IP, turn it into a product.
Source 3: Your Own Customer Feedback
Once you have products in the market, your customer support inbox becomes your R&D department. Every support ticket is a data point.
How Katie manages the feedback loop:
- Every support ticket is tagged as ‘feature request’ or ‘product idea’
- A monthly review surfaces the most common themes
- Features requested by 10+ customers go on the product roadmap
- Features requested across multiple products become standalone plugins
Validating Ideas Before You Build Anything
Katie has a simple rule: if she can’t find at least 1,000 monthly searches and weak competition, she doesn’t build it. Her validation checklist:
SEO Strategy: Dominating Google Without Paying for a Single Ad
Barn2 Plugins runs on 100% organic traffic. No Facebook ads. No Google Ads. No influencer deals. Just SEO done right, consistently, over time.
The Keyword Architecture That Drives Buying Intent
Each plugin targets a layered set of keywords:
| Keyword Type | Structure | Example |
|---|---|---|
| Primary | [Platform] + [feature] + plugin | WooCommerce wholesale plugin |
| Secondary | How to [achieve result] in WordPress | How to create product tables in WooCommerce |
| Long-tail | [Specific use case] + WordPress | Password protect WooCommerce categories for wholesale |
The Tutorial Flywheel
Katie’s team publishes two to three in-depth tutorials per month, each following a proven formula:
- Identify a specific use case that one of their plugins solves
- Create a comprehensive guide (2,000+ words) with screenshots and visuals
- Include a video walkthrough embedded from YouTube (boosts dwell time)
- Link naturally to related products within the content
- Update the post annually to stay fresh and maintain rankings
Targeting Low-Competition Niches First
Rather than competing head-to-head with established plugins, Katie looks for brand-new categories where competition is thin. Her approach:
- Find feature requests in forums with no existing plugin solutions
- Check the WordPress.org plugin directory, if top results have under 100 reviews, there’s an opportunity
- Search Google for ‘how to [feature] wordpress’ . If results are forum threads and code snippets instead of plugin pages, there’s a gap
Case Study: When Katie launched WooCommerce Product Table, only two competing plugins existed, both poorly maintained. Her comprehensive solution reached #1 on Google within 60 days.
What a Typical Ranking Timeline Looks Like
- Months 1–2: New plugin page indexed, ranking on page 3–5
- Months 3–4: With basic content, edges onto page 2
- Month 6: With tutorials and customer reviews, reaches page 1
- Month 12+: Dominates positions 1–3 for primary keywords
A well-optimized plugin page generates 500–2,000 organic visitors per month. Top tutorial posts pull 1,000–5,000. With 20 products, that adds up to 40,000+ monthly organic visitors, all without paying for a single click.
The Cross-Selling Flywheel: Where the Portfolio Really Compounds
If SEO is the engine, cross-selling is the turbocharger. This is where having multiple products stops being a management challenge and starts being a genuine competitive advantage.
The Email Sequence That Turns Buyers Into Portfolio Customers
| Timing | What Happens |
|---|---|
| Day 0 | Welcome email with setup guide and support resources |
| Day 7 | Cross-sell email: 'Customers who bought [A] also love [B]' — 50% off for 7 days |
| Day 14 | Educational email on advanced use cases; subtle mentions of complementary plugins |
| Day 30 | Feature announcement for purchased plugin + 25% off related product in the P.S. |
| Day 90 | Customer success story featuring multiple plugins; bundle offer (3 plugins for price of 2) |
In-Product Cross-Promotion
Katie’s plugins also promote each other from inside the product:
- Settings page banners: ‘Using Plugin A? You might also need Plugin B for [specific benefit]’ click-through rates of 8–12%
- Documentation links that reference complementary plugins in context
- Onboarding wizards that suggest additional tools during plugin activation
- Early-access invites for new products sent exclusively to existing customers
The Bundle Strategy
Three bundle types drive a significant share of revenue:
- Theme Bundles — All plugins for a specific use case (e.g., ‘Restaurant Bundle’)
- Pro Bundles — 5 most popular plugins at 40% off
- All-Access Pass — Entire portfolio with one year of updates for $599
The result: 15% of customers eventually buy a bundle, with an average value of $299 versus $79 for a single plugin. About 35% of customers own two or more plugins within 18 months of their first purchase.
The 2026 Playbook: Katie's 5-Step Framework for Building Your Own Portfolio
If Katie were starting from scratch today, here’s exactly what she’d do, in order.
Step 1: Start Inside Your Existing Expertise
The biggest rookie mistake is trying to build for a market you don’t understand. The ecosystem learning curve alone can cost you six months. Start where you already have depth.
- List every platform or ecosystem you know well, WordPress, Shopify, Webflow, Notion, Chrome
- Map your current skills: PHP, JavaScript, design, no-code tooling
- Choose the ecosystem with the largest addressable market where you already have knowledge
Step 2: Research 5–10 Ideas with Overlapping Audiences
The portfolio effect only works when your products serve related customer bases. That overlap is what makes cross-selling possible. Build a spreadsheet and rate each idea by: search volume, competition level, estimated price, and most critically, what percentage of your Product A customers would also need Product B.
Target: Find 5–10 ideas where at least 30% of customers would need more than one product.
Step 3: Launch Product 1 — Go Deep Before Going Wide
Your first product is the foundation everything else gets built on. Don’t rush to product #2 until product #1 is earning consistent revenue. Katie’s threshold: $2,000/month or 100 active customers before moving on.
Step 4: Launch Product 2 — Activate the Cross-Sell
When choosing your second product, let your existing customer base guide you. Look at your support tickets, your feature requests, and the adjacent problems your Product #1 customers are trying to solve. Your second product should make your first product more valuable, not compete with it.
Step 5: Scale the Portfolio Systematically
By the time you reach 5–6 products, the flywheel should be spinning. Each new product gets a warm audience on launch day, built-in cross-sell potential, and a distribution channel that already exists. At this stage, the focus shifts from building individual products to managing and optimizing the portfolio as a system.
10 Core Principles from Katie's Journey
Distilled from years of building, these are the principles that matter most:
- Start small, think portfolio: Your first product doesn’t need to be perfect, it needs to be the foundation.
- Overlapping audiences multiply revenue: Choose products that serve related customer bases for maximum cross-sell potential.
- SEO beats paid ads for longevity: Organic traffic compounds over time. Paid traffic stops the moment you stop paying.
- Customer feedback is your R&D: Your best product ideas come from the people already using your products.
- Cross-selling is the secret weapon: Portfolio revenue grows faster than linear product additions.
- Launch fast, iterate forever: Ship the MVP, then improve based on real user feedback.
- Niche dominance beats broad competition: Be the #1 solution for a specific problem rather than #20 for a general one.
- Infrastructure should scale: Use tools and systems that work for 1 product or 100.
- Focus on your top performers: Not all products deserve equal time and attention.
- Build for the long term: Katie’s oldest plugins still generate revenue 8+ years later.

Final Thoughts: The AI Era and the Portfolio Advantage
In 2026, AI tools have made building software faster and cheaper than at any point in history. That lowers the barrier to entry, but it also raises the stakes for differentiation.
“In the age of AI, anyone can build software. But they can’t easily build trust, audience, and customer relationships. That’s what a portfolio gives you, multiple touchpoints to prove your value and multiple opportunities to serve your customers.” Katie Keith, Barn2 Plugins
Katie’s real competitive moat isn’t the code; it’s the customer relationships, the SEO authority built over the years, the cross-selling infrastructure, and the brand trust that compounds with every product launch. Those things are genuinely hard to replicate quickly.
Her journey from zero to $1.8M didn’t happen overnight. It took consistent execution, a willingness to learn from every product, and the patience to let the portfolio effect do its work.
“Stop waiting for the perfect idea. Just launch something. Once you get something into the world, opportunities start coming your way. Your second product will be better than your first. Your fifth will be better than your second. But you can’t get to five without starting with one.” Katie Keith
The path forward is clear: pick one idea, spend 30 days building an MVP, and launch it. Everything else, the second product, the cross-sells, the bundles, the SEO authority, follows from that first step.
