AI Landing Pages for Google Ads: The PixelWheels Case Study

PixelWheels rents mobile LED billboards in Auckland and Christchurch. They needed landing pages, ad campaigns, and a custom domain. Synter built all three in a single chat session.

The Brief

PixelWheels (pixelwheels.nz) rents mobile LED billboard trucks in Auckland and Christchurch, New Zealand. They offer three distinct services: LED screen hire for events, mobile billboard advertising for brand campaigns, and digital signage installations for retail and hospitality.

The problem was common among local service businesses: one generic website trying to rank for three different service categories. Each service has different buyer intent, different search keywords, and different objections to address. Sending all Google Ads traffic to a single homepage wastes clicks.

PixelWheels needed dedicated landing pages for each service, matching ad campaigns, and everything hosted on their own domain. Synter built all of it in a single session.

What Synter Built

Three landing pages, three Google Ads Search campaigns, and a custom domain. Here's the breakdown.

Landing Pages

Each page was generated from a chat prompt, customised with PixelWheels' brand colours (green #00FF00, secondary #00CC00), and published to a dedicated slug:

ServiceLanding Page URLFocus
LED Screen Hirego.pixelwheels.nz/pixelwheels-led-screen-hireEvents, concerts, corporate functions
Mobile Billboardgo.pixelwheels.nz/pixelwheels-mobile-billboardOutdoor brand awareness, route-based advertising
Digital Signagego.pixelwheels.nz/pixelwheels-digital-signageRetail, hospitality, permanent installations

Each page includes a clear headline, service benefits, a call-to-action with the PixelWheels phone number (0800 447 493), and responsive design for mobile visitors.

Custom Domain

Rather than using the default syntermedia.ai/lp/ URLs, the pages are served from go.pixelwheels.nz. Setting this up required a single CNAME record pointing to cname.vercel-dns.com and a domain verification call through Synter's API.

This matters for Google Ads. Ad platforms penalise cross-domain redirects, so the click URL domain needs to match the landing page domain. With a custom domain, the ads link directly to go.pixelwheels.nz/... with no redirects.

Google Ads Campaigns

Three Search campaigns, each targeting New Zealand (Geo ID 2554) with Manual CPC bidding at $3.00 NZD max CPC:

CampaignDaily Budget (NZD)Landing Page
LED Screen Hire NZ$10.67go.pixelwheels.nz/pixelwheels-led-screen-hire
Mobile Billboard Hire NZ$9.67go.pixelwheels.nz/pixelwheels-mobile-billboard
Digital Signage Hire NZ$13.00go.pixelwheels.nz/pixelwheels-digital-signage

Each campaign has a Responsive Search Ad with 8 headlines and 2 descriptions, tuned to the local New Zealand market. Keywords target phrases like "LED screen hire Auckland," "mobile billboard NZ," and "digital signage Christchurch."

Call extensions were added with the 0800 number, giving mobile searchers a tap-to-call option directly from the ad.

Why Dedicated Landing Pages Win

Sending ad traffic to a homepage is the most common mistake in paid search. Here's what happens when you use dedicated landing pages instead:

Higher Quality Score

Google rewards ad-to-page relevance. When the search query, ad copy, and landing page all align around "LED screen hire," Quality Score goes up. That means lower CPCs and better ad positions for the same budget.

Better Conversion Rates

A visitor searching for "mobile billboard hire Auckland" lands on a page that says exactly that, with pricing, photos, and a call-to-action. No digging through navigation menus. No competing messages.

Clearer Attribution

Each landing page maps to one campaign. If LED screen hire converts at 8% but digital signage converts at 2%, you know exactly where to increase budget and where to improve.

Faster Page Load

Generated landing pages are lightweight HTML. No CMS bloat, no third-party widgets, no render-blocking scripts. Fast load times improve both user experience and Google's landing page experience score.

How the Landing Page Pipeline Works

Synter's landing page system follows a strict pipeline to balance flexibility with security:

1. Generate

The AI generates a self-contained HTML page from a chat prompt. It applies the client's brand colours, adds relevant copy for the target service, and includes structured calls-to-action.

2. Sanitise

All generated HTML passes through a sanitiser that strips scripts, event handlers, and dangerous URLs. This is defense in depth, since the AI is trusted but the output is treated as untrusted.

3. Enhance

After sanitisation, trusted enhancements are injected back in: analytics beacons, approved embed scripts (YouTube, LinkedIn), and mobile sticky CTAs. Each gets a unique CSP nonce.

4. Inject Tracking

Platform pixels (Google, Meta, LinkedIn, Reddit, TikTok) are injected with nonces for CSP compliance. A first-party Synter beacon tracks page views and CTA clicks without any external dependencies.

5. Serve

Pages are served with full Content-Security-Policy headers, custom domain support via middleware rewrites, and 60-second caching for performance.

Technical Details

Custom Domain Routing

When a request hits go.pixelwheels.nz, Next.js middleware detects that the host isn't a main Synter domain and rewrites the path to /lp/custom-domain/go.pixelwheels.nz. The handler looks up the page by custom_domain + domain_verified + published flags and serves it through the full sanitise-enhance-inject pipeline.

Campaign Structure

Each Search campaign follows a simple, auditable structure:

  • 1 campaign per service with its own daily budget
  • 1 ad group per campaign with tightly themed keywords
  • 1 RSA per ad group with 8 headlines and 2 descriptions
  • Manual CPC at $3.00 NZD max for full budget control
  • Geo-targeting: New Zealand only (Geo ID 2554)
  • Call extensions with 0800 447 493 for mobile users

Manual CPC was chosen deliberately. For a new account without conversion history, automated bidding strategies like Maximize Conversions have nothing to optimise against. Manual CPC lets the business owner control costs from day one and switch to automated bidding once enough conversion data accumulates.

Brand Customisation

The landing pages use PixelWheels' brand green (#00FF00) rather than Synter's default lime (#9CFF5A). This is handled at generation time by overriding the brand colour in the prompt. The Synter badge is still present on hosted pages (it's unconditionally injected), but the page content itself is fully on-brand for PixelWheels.

What This Replaces

Building what Synter produced in this session would traditionally require:

TaskTraditionalWith Synter
3 landing pages (design + dev)1-2 weeks, $2,000-5,000Minutes, included in plan
Custom domain setupDNS config + SSL + hosting, 1-3 daysCNAME record + API verification
3 Google Ads campaignsKeyword research + ad copy + setup, 3-5 daysGenerated from chat, minutes
Tracking setupPixel installation + GTM + testing, 1-2 daysAuto-injected with CSP nonces

For a local business spending $30-35 NZD per day on ads, spending $5,000+ on landing pages and agency setup fees doesn't make sense. Synter compresses the entire workflow into a conversation.
