12 A/B testing & experimentation stats you need to know in 2026

For many years now, digital experimentation has been moving away from isolated page tests and more broadly towards how companies make decisions. 

The companies best poised for growth are testing more consistently, integrating marketing and product more tightly, and sharing metrics that guide how the entire company operates. 

What do you ship? What do you change? What needs to be left alone? More and more, experimentation answers these crucial questions. Here are the stats that tell the story.

1. 84% of marketers run A/B tests at least monthly

24% of marketers test monthly, 38% test weekly, and 22% test daily. That’s a strong signal that more and more companies are integrating experimentation into their very culture, and it is becoming a core part of the marketer’s toolkit (source: Ascend2’s 2025 A/B Testing Report).

2. 46% of marketers say they have a comprehensive, regularly-updated testing strategy

If frequency is a strong signal, strategy is a stronger one: in the same report, almost half of marketers indicate the existence of a durable framework that is designed to help programs scale cleanly. A documented testing strategy is often the difference between isolated experiments and a true learning system (source: Ascend2’s 2025 A/B Testing Report).

3. 87% of mature experimentation programs standardize processes, documents, and test results

In Speero’s analysis of experimentation programs, standardization appears as a major marker of maturity. The teams running the strongest experiments standardize their process so other teams in the same organization can follow their lead (source: Why Mature Programs Grow Faster: Speero + Kameleoon Original Research).

4. Businesses with mature testing programs are 69% more likely to grow significantly

The same analysis found that companies are 69% more likely to grow significantly with mature testing programs. Again we see that moving away from isolated, single-page tests correlates positively with business momentum, learnings, and success (source: Why Mature Programs Grow Faster: Speero + Kameleoon Original Research). 

5. 65% of CRO agencies say their clients are shifting tests in-house

Ownership for experimentation is moving closer to the business. That indicates a genuine shift, as running experimentation in-house requires better processes, reporting, and collaboration to succeed (source: Convert.com’s 2025 CRO Agency & Vendor Ecosystem Report)

‍6. 49% of companies say web experimentation is a high-investment priority

Just under half of respondents to the 2025 Experimentation-led Growth Report listed web experimentation as a high priority, indicating that “classic” website testing is still an important part of experimentation in 2026 (source: The 2025 Experimentation-led Growth Report by Kameleoon). 

7. 47% of companies say feature experimentation is a high-investment priority

The same survey found that feature experimentation is becoming less of a specialty workflow and more common across industries. It is listed at nearly at parity with web experimentation, a clear sign of a shifting industry (source: The 2025 Experimentation-led Growth Report by Kameleoon). 

8. 35% of testing businesses have fully integrated their experimentation technology across marketing, product, and engineering teams

Perhaps the more interesting statistic is the inverse: 65% of businesses running experiments haven’t fully integrated their technologies. Disconnected tools, processes, and operations make it harder to scale experimentation across teams, channels, and use cases, and limit A/B testing to simple, page-level ideas (source: The 2025 Experimentation-led Growth Report by Kameleoon). 

9. Among companies expecting growth, 51% invest heavily in web experimentation; among those not expecting growth that number is only 23%

Investing heavily in A/B testing correlates with confidence. Organizations expecting growth are materially likelier to keep investing in web experimentation, suggesting that testing is part of how they plan to capture that growth (source: The 2025 Experimentation-led Growth Report by Kameleoon). 

10. Similarly, 50% of companies expecting growth invest heavily in feature experimentation; among those not expecting growth, that number is 15%

The gap is even sharper on the feature side, where companies expecting growth are more than three times likelier to go beyond front-end website tests and invest in feature experimentation (source: The 2025 Experimentation-led Growth Report by Kameleoon).

11. With the growing presence of AI in experimentation platforms, the use of graphic and code editors has declined by over 50%.

Kameleoon’s own internal product data highlights a trend: as AI tools like Prompt-based Experimentation (PBX) improve, the teams are moving away from traditional page editors and towards more efficient, modern practices for ideating, building, and analyzing experimentation (source: Kameleoon).

12. In a meta-analysis of 1,001 A/B tests, only 33.5% produced a statistically significant positive result‍

This is a timely reminder that most A/B tests do not produce clean winners, and that statistical design still matters enormously. Sequential methods and variance reduction approaches are becoming more and more important as mature teams need to learn faster without weakening rigor (source: Analytics Toolkit’s 1,001-test meta-analysis).
