--- title: "CRO & A/B Testing Add-On — TechTailors" description: "We design A/B and multivariate tests, set them up, report every result, and roll out the winners." canonical: https://techtailors.agency/services/cro-testing/ --- # CRO & A/B Testing Add-On We design the A/B and multivariate tests, set them up, report every result and roll out the winners. The testing tool runs in a VWO account you own. [Price Your Build](https://techtailors.agency/pricing/calculator/) From $3,000 a month ## Experiments that find what converts From copy tweaks to full-funnel experiments, our CRO (Conversion Rate Optimization: improving the percentage of visitors who take desired actions) add-on *tests what moves your numbers*: sales, signups or whatever else you measure. We plan the experiments, run them and act on the results. **Vendor configuration required** CRO & A/B Testing requires **VWO Pro or above** in an account you own (Enterprise encouraged) as a Mandatory Minimum Vendor Configuration (Mandatory Minimum Vendor Configuration: the minimum vendor plan required for TechTailors to deliver the advertised SLA and feature set. SLA guarantees are conditional on maintaining this configuration.), plus any analytics tools your testing program needs. From Tier 3 (300K–600K visitors, 5–6 tests) up, we strongly recommend **VWO Enterprise** for advanced targeting, server-side testing, session recordings and heatmaps: VWO Pro may hit performance limits at that traffic. VWO quotes Enterprise pricing itself, and we’ll help you weigh it during onboarding. $1,000 once, any plan ## Start with a one-time CRO Audit Every plan can buy the CRO Audit: a flat **$1,000** conversion review that needs no testing platform. - **Heuristic review:** Your pages, checked against established usability frameworks. - **Funnel mapping:** From landing page to conversion. - **A prioritized fix list:** Recommendations we can act on right away, since edits are unlimited for the life of your monthly plan. Continuous A/B testing needs traffic most small sites don’t have yet: on a low-traffic page, a statistically honest test can take months to conclude. Once yours can support testing, any plan can add the retainer, and the audit’s findings become its first hypotheses. Your plan sets the support response time: 48 hours on Smart Casual, 24 on Professional, 16 on Black Tie. Reviewed monthly or bi-weekly ## What the retainer covers ### Experiments - **Experiment design:** We find high-impact test opportunities, write clear hypotheses and design A/B or multivariate (A/B testing compares two versions; multivariate tests multiple variations at once) experiments that show what drives conversions. (The wrong A/B test wastes 2–4 weeks and tells you nothing. The right one isolates a single decision moment (button copy, form field order, image or no image), so you can pin the result on the one variable you changed. That’s the difference between “we ran a test” and “we learned something.”) - **Hands-on implementation:** We work with your developers, or manage every change end to end if you’re a full-service client, so each test is set up accurately. - **Analytics included:** Built-in analytics and a managed testing workflow that plug into your other TechTailors services, with no extra tools needed to start. ### Results - **A report on every result:** Win, loss or inconclusive, you hear about each outcome, with the why behind it and the next steps we propose. - **Roadmap revisions:** Each review period, set by your tier, we revise your CRO roadmap: winning variants roll out site-wide, new experiments are queued by priority, and tests that underperform pivot or end. - **A fast pause if a test breaks:** Whatever your plan, we pause the test as soon as we spot the problem or you tell us, and your original page comes straight back. **Timeliness SLA** If we miss an update or a test deadline, our SLA (Service Level Agreement: a guaranteed commitment with compensation if missed) takes $500 off your next invoice. Every plan ## Four tiers, set by your traffic or revenue Starting at $3,000 a month We place you in a tier automatically, by a 3-month rolling average of your monthly visitors or revenue. Each tier is $1,500 more than the one below. - Tier 1: Up to 150K visitors or $75K revenue. Monthly reviews, up to 2 tests at once. $3,000 a month - Tier 2: 150K–300K visitors or $75K–$200K revenue. Monthly reviews, 3–4 tests at once. $4,500 a month - Tier 3: 300K–600K visitors or $200K–$500K revenue. Bi-weekly reviews, 5–6 tests at once. $6,000 a month - Tier 4: Over 600K visitors or $500K+ revenue. Bi-weekly reviews, 7–8 tests at once. $7,500 a month Each tier caps how many tests run at once and sets how often we send updates on results, suggestions and next steps. Pair it with [Analytics & Tracking](https://techtailors.agency/services/analytics/) and save $500 a month. ### Which plans carry it 1.

Step 2 ### Plan and launch tests We propose the order of tests, then configure and launch each one. Step 3 ### Watch each test If a test pulls ahead by a clear margin before its end date, we end it early or pivot to new variations. Step 4 ### Report and roll out We share what we learned and roll out the winning variants. If a test is inconclusive, we refine it or pivot. Step 5 ### Revisit the roadmap Each review period (monthly or bi-weekly, by tier), we reassess where your CRO roadmap stands. ## Explore more ### Related services - [**Analytics & Tracking Add-On** Smart Casual · Professional · Black Tie · White Tie](https://techtailors.agency/services/analytics/) - [**Digital Advertising Add-On** Smart Casual · Professional · Black Tie · White Tie](https://techtailors.agency/services/digital-advertising/) - [**E-Commerce Add-On** Smart Casual · Professional · Black Tie · White Tie](https://techtailors.agency/services/ecommerce/) ### From the blog Mar 5, 2026 2 min read #### [Edge-First Architecture Explained](https://techtailors.agency/blog/edge-first/) In Google's PageSpeed test, our server answers in about 10 ms and the page paints in under half a second on desktop.
