Every week someone asks: "Why should I pay for a developer when Wix has AI that builds websites in 3 minutes?"
Fair question. AI website builders have gotten impressive. Wix ADI, 10Web AI Builder, Durable, Framer AI — they're all fast, cheap, and produce something that looks like a website.
But after building 25+ websites for real businesses and testing 12 AI builders, here's what actually happens when businesses choose AI vs a real developer.
What AI Builders Are Actually Good At
Let's start with what works. AI website builders excel at:
- Speed: You can have a site live in under an hour
- Low barrier: No technical knowledge needed
- Templates: They generate decent-looking layouts based on your industry
- Basic content: AI can write placeholder text that's 70% usable
If you need a quick landing page for a side project, a portfolio to show 3 samples, or a placeholder while you build something real — AI builders are fine.
Where AI Falls Apart (And Costs You Customers)
The problems appear after launch. Here's what we see when clients come to us from AI builders:
1. SEO That Doesn't Work
AI builders generate generic meta descriptions and H1 tags. They don't understand local SEO, schema markup, or how to optimize for "dentist Birmingham" vs "Birmingham dental services."
Result: You rank on page 3-5 for searches your competitors dominate. Google traffic: 20-40 visits/month instead of 200+.
2. Mobile Performance Issues
Most AI sites score 40-60 on Google PageSpeed Mobile. That's bad enough to hurt rankings. Real developer sites we build average 90+.
The difference? A slow site loses 53% of mobile visitors within 3 seconds (Google data). That's half your potential customers gone.
3. Cookie-Cutter Design
AI builders have 50-100 templates. Your competitors use the same ones. When 3 plumbers in Manchester have identical Wix layouts, differentiation dies.
4. Hidden Costs Pile Up
- Wix: £17-30/month (£204-360/year)
- 10Web AI: $10-30/month ($120-360/year)
- Durable: $15-25/month ($180-300/year)
After 2 years, you've spent £400-720. A custom developer site costs £250-650 once and you own it.
5. You're Locked In
Try moving your Wix site to another platform. You can't export the design. You have to rebuild from scratch. AI platforms know this — that's their business model.
The Real Cost Comparison
Let's compare a UK restaurant needing a 5-page website with online ordering:
AI Builder (Wix):
- Setup: £0-50
- Monthly fee: £25 × 24 months = £600
- SEO plugins: £15/month × 24 = £360
- Total 2-year cost: £960-1,010
- Result: Generic template, poor SEO, 40-80 visitors/month
Real Developer (Us):
- One-time cost: £300-500
- Hosting: £8/month × 24 = £192
- Total 2-year cost: £492-692
- Result: Custom design, local SEO, 200-400 visitors/month
The AI builder costs 50-100% MORE over 2 years. And gets worse results.
When AI Builders Make Sense
Three scenarios where AI is the right choice:
- Testing an idea: You're not sure if the business will work and need something live in 24 hours
- Temporary placeholder: You're building a real site but need something now
- Zero budget: You literally have £0 and can't wait 2 weeks for a developer
That's it. For any real business expecting to be around in 12 months, a developer makes more financial sense.
What About AI-Assisted Development?
Here's where it gets interesting. We USE AI tools (GitHub Copilot, ChatGPT, v0) to build sites faster. But a human developer:
- Writes proper SEO schema
- Optimizes images for mobile
- Fixes accessibility issues AI misses
- Integrates real payment systems
- Customizes everything to your brand
AI assists. Humans verify, optimize, and deliver results that actually generate leads.
The Lead Generation Test
We ran an experiment. Same business (landscaping, Birmingham), two websites:
Site A: Built with Wix ADI in 1 hour Site B: Built by our team in 5 days
After 60 days:
- Site A: 12 enquiries, 2 conversions
- Site B: 47 enquiries, 9 conversions
Site B cost 3× more upfront. Generated 4.5× more revenue. ROI isn't close.
Bottom Line
AI website builders are impressive technology. But they're solving the wrong problem.
The hard part of a business website isn't "can it exist?" — it's "does it generate customers?" AI builds sites. Developers build lead generation systems.
If you want a website that looks professional, ranks on Google, and converts visitors into paying customers, you need a human who understands SEO, copywriting, and local search behavior.
That developer doesn't have to be expensive. But they do have to be real.
