Best landing page builders with A/B testing and analytics (2026)
The short answer
For small businesses running paid campaigns, Leadpages and Unbounce both build landing pages with A/B split testing; Instapage targets larger ad budgets with personalisation. Kartra suits coaches and course sellers who want pages, funnels, email and checkout in one system. Carrd is the low-cost choice for a simple one-page site without testing.

Analytics1 Score result
#1 landing page builders with A/B testing and analytics, by the Analytics1 Score: Unbounce (93/100)
Scored from vendors’ own published pages with fixed weights; partner and sponsor status are not inputs. How the score works.
How to choose
- Split testing built in saves a separate testing tool, if you have the traffic for it.
- Tracking: easy GA4 and Google Tag Manager installation, ad pixels and hidden fields that pass UTMs into the form.
- Speed on mobile: paid traffic is mostly mobile, and slow pages waste spend.
- Integrations with your CRM and email platform, so every lead lands with its source.
- Pricing limits: page, domain, visitor or lead caps.
Check the maths before you test: the A/B test calculator tells you how many visitors a test needs.
The ranking
Ranked by the Analytics1 Score, from evidence read on each vendor’s own site on 19 October 2026. Affiliate partners and sponsors are scored by the same rules as everyone else: being a partner or buying a placement has no effect on a score or a position. We have not tested these products in a live account.

Make the landing page measurable
- Install GA4 through Google Tag Manager and fire generate_lead on the thank-you page or form success, not on button clicks. See GTM form submission tracking.
- Pass utm_source, utm_medium and utm_campaign into hidden form fields so the CRM keeps the source.
- Use one landing page per campaign promise; mixing traffic hides which message works.

Questions
- Do I need a landing page builder if I have a website?
- Not always. A builder helps when you run many campaigns and want pages without developer time, plus built-in split testing. If you run one or two campaigns, a dedicated page on your existing site may be enough.
