CRO & A/B Testing Add-On

Turn visitor data into real conversions — strategic A/B and multivariate experiments, hands-on implementation, data-driven reporting, and continuous optimization to find what actually converts.

How it works

From copy tweaks to full funnel experiments, our CROConversion Rate Optimization: improving the percentage of visitors who take desired actions add-on tests what actually moves your numbers for sales, signups, and whatever else you're measuring. We plan the experiments, run them, and act on the data so improvements compound over time.

Pair with Advanced Analytics for a $500/mo. discount. Works well with most other add-ons too. The retainer is available on Black Tie plans and above; the one-time CRO Audit below is available on every plan.

CRO Audit: the one-time starting point

Continuous A/B testing needs traffic most small sites don't have yet: a statistically honest test on a low-traffic page can take months to reach a conclusion, which is why the full retainer sits at Black Tie. The CRO Audit is the version every plan can buy: a one-time, flat $1,000 conversion review with no testing platform required.

You get a heuristic review against established usability frameworks, session-replay analysis using the analytics stack already in every TechTailors build, funnel mapping from landing page to conversion, and a prioritized recommendation list your unlimited edits can act on right away. When your traffic grows into testing territory, the audit's findings become the retainer's first hypotheses.

Key Features

  1. Timeliness SLAService Level Agreement - a guaranteed commitment with compensation if missed: If we ever miss an update or a test deadline, we'll credit you $500 off your next invoice.
  2. Strategic Experiment Design: We pinpoint high-impact test opportunities, create clear hypotheses, and design A/B or multivariateA/B testing compares two versions; multivariate tests multiple variations at once experiments to uncover what genuinely drives conversions.The wrong A/B test wastes 2–4 weeks and tells you nothing. The right test isolates a specific user-decision moment (button copy, form field order, image vs no-image) so the result is actually attributable to the one variable you changed. Good experiment design is what separates “we ran a test” from “we learned something.”The wrong A/B test wastes 2–4 weeks and tells you nothing.

  3. Hands-On Implementation: Our team coordinates with your developers or manages changes end-to-end if you're a full-service client, ensuring seamless, accurate test setups.
  4. Data-Driven Insights & Reports: Transparent updates on test outcomes: wins, losses, or inconclusive. We highlight the "why" behind each result and propose logical next steps.
  5. Continuous Optimization: Each period (depending on your tier), we revise your CRO roadmap. Successful variants roll out site-wide, new experiments are prioritized, and low-performing tests pivot or conclude.
  6. Basic Analytics Included: Built-in analytics and a managed testing workflow that plugs seamlessly into your existing TechTailors services, no extra tools needed to get started.

T3/T4: When to upgrade to VWO Enterprise Show less

At Tier 3 (300K–600K visitors, 5–6 tests) and above, we strongly recommend upgrading to VWO Enterprise for advanced targeting, server-side testing, session recordings, and heatmaps. VWO Pro may introduce performance constraints at these traffic levels. Pricing is custom-quoted by VWO. We'll help you evaluate during onboarding.

This add-on, like every TechTailors add-on, begins billing once we start implementing this add-on into your website: see pricing FAQs for details on how billing and onboarding work.

How we compare? Hide comparison

Our CRO ladder is $3,000 to $7,500/month in $1,500 increments. The entry price meets industry mid-tier for credibly managed CRO, and our ceiling sits well below the mid-tier ceiling. The VWO license stays on your account, not ours, so you're never paying us a markup on the testing tool. We also flag when a VWO Enterprise upgrade actually makes sense at T3+, so you don't leave advanced features on the table.

And unlike most peers, every third-party tool license (Semrush, VWO, Crowdin, Cloudflare, Stripe, etc.) sits on your account per our vendor-account-ownership architecture : no agency-marked-up tool fees, no goodbye-fee on offboarding.
