Dynamically swap landing page hero images with UTM parameters. Boost CTR, cut bounce, and increase ROAS by matching ad creative to landing visuals.
Generic landing pages kill performance.
When a user clicks an ad for “50% off running shoes” but lands on a page with a generic lifestyle image, the disconnect creates friction.
The result: lower CTR, higher bounce rates, and wasted ad spend.
Digital ads work because they’re hyper-specific. But if your landing pages don’t reflect that same specificity, your ROAS tanks. Marketers can’t afford to lose clicks at the finish line.
ConversionWax makes every landing page feel like an exact extension of the ad.
The result: every user sees the exact creative that matches the ad they clicked. No disconnect, no wasted spend.

These gains happen because personalization reduces the gap between what the user expects and what they see. Friction disappears, intent flows into action.
A mobile-optimized image uses a mobile-friendly aspect ratio (e.g., 4:5, 3:4, or 1:1), keeps the CTA visible in the first viewport, preserves subject focus in crop, and uses modern formats (WebP/AVIF) with sensible fallbacks. ConversionWax then auto-optimizes delivery per device.
Run until you reach adequate sample size and statistical confidence (commonly 95%). As a rule of thumb, 1–2 weeks with steady traffic is a good baseline—avoid stopping early due to variance.
Automatic optimization equalizes file weight across variants so you primarily measure layout and messaging—not bytes. If you want to test heavy vs. optimized assets as the variable, run a separate experiment.
Yes. Use URL variable targeting with UTMs to scope the experiment to paid cohorts and compare against organic traffic.
Use multi-linking personalization so each variant/device has a unique destination URL parameter. This preserves attribution through your analytics platform and ties conversions to the exact creative.
Often, yes. Start with the mobile image showdown. Once you have a winner, layer location-based or time-based personalization to find high-performing pockets such as specific cities or morning vs. evening visitors.
Match your layout. For full-bleed mobile heroes, common ratios are 4:5, 3:4, or 1:1. Keep key content and CTAs in safe zones and validate across common device breakpoints.
