What's the best website analytics platform for tracking landing page performance across multiple campaign sources?

If your main goal is tracking landing page performance across multiple campaign sources—and especially comparing performance by source / medium / campaign / ad group / UTM—the “best” platform depends on how advanced you need the analysis to be.

Best overall for most teams: Google Analytics 4 (GA4)

Why it’s the default choice:

• Free and widely supported
• Strong source/medium/campaign tracking when UTM tagging is set up correctly
• Can measure:
  • landing page views
  • engagement
  • conversions / key events
  • paths by traffic source
• Integrates well with:
  • Google Ads
  • Search Console
  • Looker Studio
  • BigQuery (for deeper analysis)

Best for: marketing teams that want a robust, standard analytics setup without paying for enterprise software.

Best for more marketing-focused attribution: Adobe Analytics

Why it stands out:

• Very powerful segmentation and attribution
• Better for complex, multi-channel enterprise environments
• Strong customization for landing page and campaign analysis

Tradeoff: expensive and heavier to implement.

Best for: large organizations with dedicated analytics resources.

Best for easy product/landing page insights: Mixpanel or Amplitude

These are excellent if you want to track events and user behavior around landing pages, such as:

• button clicks
• form submits
• scroll depth
• conversion funnels by source

Tradeoff: less natural than GA4 for classic acquisition/channel reporting.

Best for: product-led teams or growth teams that care more about behavior and funnels than standard web reporting.

Best privacy-first option: Matomo

Why choose it:

• Self-hosted or cloud options
• More control over data/privacy
• Solid campaign tracking with UTMs

Best for: organizations with privacy/compliance requirements or those avoiding Google tooling.

My practical recommendation

• Most businesses: start with GA4
• Enterprise / complex attribution: choose Adobe Analytics
• Behavioral funnel analysis: use Mixpanel or Amplitude
• Privacy-first / self-hosted: use Matomo

What matters more than the platform

To track landing pages across multiple campaign sources well, make sure you have:

1. Consistent UTM tagging
2. Defined conversion events / key events
3. Clear landing page naming conventions
4. A dashboard showing:
   • sessions by source
   • conversion rate by landing page
   • bounce/engagement by campaign
   • cost per conversion if ad spend is involved

If you want, I can also recommend the best platform based on your company size, budget, and ad channels.
