Optimizely Web Experimentation Pricing 2026 (With Sourced Numbers)

Optimizely Web Experimentation is the testing-only SKU within the broader Optimizely platform. Buying it standalone (without Personalization, Feature Experimentation, CMS, or Commerce) is the cheapest entry point into Optimizely. Vendr data shows standalone Web Experimentation contracts typically land at the lower end of the Optimizely range.

What Optimizely Web Experimentation costs

Optimizely does not publish per-SKU pricing. Buyer data from Vendr and public reviews suggests:

Pricing scales primarily with monthly tracked users (MTUs). MTUs are unique visitors who hit a page running an active experiment within a calendar month. Buyers consistently underestimate MTU consumption: a single experiment running across a high-traffic homepage can burn through a small-tier MTU allowance within days.

Annual contracts are standard. Multi-year terms (2-3 years) typically yield 20-30% off list pricing. Adding any other SKU (Personalization, Feature Experimentation, CMS) roughly doubles or more the contract value. Full TCO breakdown is in the Optimizely pricing analysis.

What Web Experimentation includes (and what it doesn't)

Included:

• A/B and multivariate testing on browser-rendered pages
• Visual editor for creating variants without code
• Multi-armed bandit (Stats Accelerator) for traffic allocation
• Statistical engine with sample ratio mismatch (SRM) detection
• Audience targeting (geographic, technographic, URL-based)

Not included (separate SKUs required):

• Personalization (audience-segment content delivery, Auto-Personalization, recommendations)
• Feature flags / server-side experimentation (Feature Experimentation SKU)
• CMS / content management (Content Cloud SKU)
• Commerce capabilities

Cheaper alternatives at the testing-only tier

VWO is the closest like-for-like replacement on testing depth. Convert.com is a strong fit for SMB teams that want flat-rate testing with all features included. Statsig fits engineering-led teams. ConversionWax covers per-banner A/B testing as part of a broader website personalization product, not as a dedicated CRO suite. Full breakdown by buyer profile is in the seven Optimizely competitors guide.

When Optimizely Web Experimentation is worth it

• Your testing program is mature and structured. 30+ tests per quarter, dedicated CRO headcount, statistical literacy on the team.
• You need multi-armed bandit and SRM detection. Stats Accelerator and Optimizely's statistical engine are deeper than VWO's or Convert's.
• Enterprise compliance matters. SOC 2, HIPAA, custom data residency, dedicated support tier.
• You plan to add more SKUs. If Personalization, Feature Experimentation, or CMS are on the roadmap, the consolidated contract makes more sense than buying separate vendors.

When the math doesn't work

• Testing volume is under 10 experiments per quarter. The platform fee per experiment becomes very high. VWO or Convert at one-tenth the cost is the better math.
• Marketing-team-led testing. If your testing program is two banner variants on the homepage, Optimizely's machinery is overkill. ConversionWax includes per-banner A/B at $99/month.
• SMB or mid-market budget. Optimizely's small-tier minimum at $40K/year is the tier most SMBs cannot or should not justify.
