Banking A/B tests we've caught

The hero section shows at least three distinct variants across visits: Visit 1 & 4 (Safari/Edge) show 'Congrats! You're invited. / You've landed an opportunity to earn a $100 bonus.' with a 'Continue' CTA; Visit 2 (Chrome) shows 'Welcome! A good friend sent you our way. / You're getting $100 when you open a new Ally Bank account and meet the requirements.' with a 'Review & Get $100' CTA; Visits 3 & 5 (Firefox/Chrome) show 'A good friend sent you our way. / It pays to have a financial ally. $100 to be exact.' with an 'Enroll' CTA. These are clearly different hero headline, subhead, and CTA label variants appearing across multiple browsers of the same engine type, confirming a real A/B test rather than browser rendering differences.

The savings calculator/comparison section in the hero differs between variants: the control shows a 'See how you compare to other banks' interactive comparison tool with a 'View Results' CTA, while the variant shows a 'Start Saving with our high-yield rate' layout with different input fields and a 'Open an Account' CTA button. The server-side routing confirms separate funnels (high-yield-savings vs high-yield-savings4).

Visits 1, 2, and 3 (Safari, Chrome, Firefox) show a 'Get started with one of our most popular accounts' section with simple account type cards and no tab navigation, while visits 4 and 5 (Edge, Chrome) show a 'Find the Right Account for You' section with a tabbed navigation bar (Popular Accounts, Brokerage & Trading, Retirement, Education & Custodial, Banking) above the account cards. The section headline, tab structure, and layout differ meaningfully between the two groups.

The hero banner rotates through different promotional offers across visits: visits 1–4 show a Chase Sapphire Preferred '100,000 bonus points' offer, while visit 5 shows a 'Enjoy $400 – New Chase checking customers' offer. The three product cards below the hero also vary (e.g., Payment Solutions vs Chase Auto vs Travel Protection Benefits), and the mid-page promotional sections differ (e.g., $125 Zelle bonus vs $200 savings bonus vs Freedom Unlimited card). These are consistent with a rotating carousel/personalization system showing different content slates, not a controlled A/B test.

The hero section shows two distinct variants: visits 1, 3, and 4 show 'Modern banking, better benefits.' with an Ally Bank Spending Account theme and a phone mockup showing 'You just got paid 2 days sooner', while visit 5 shows 'Open both, save more.' with a different headline, subhead copy, hero image (couple laughing), and a 'Savings Round Up' widget. Visit 2 shows the same 'Modern banking' hero as visits 1/3/4 but has a different bottom CTA section ('Bank on Buckets.' WNBA partnership banner) instead of 'Chase your money dreams with an ally by your side.' Both the hero and the bottom promotional section differ across visits, consistent with an active A/B or multivariate test.

The hero banner rotates through different slides across visits: Visit 1 (Safari) shows 'Take transferring accounts off your to-do list', Visit 2 (Chrome) shows 'Invest today and plan for tomorrow', Visit 3 (Firefox) shows 'Moving money made easy', Visit 4 (Edge) shows 'Our crypto experience has you covered', and Visit 5 (Chrome) shows 'Moving money made easy'. These are different positions in a hero carousel/marquee, not a controlled A/B test.

In visit 5 (Chrome), the 'How can we help?' navigation icons show a different order: 'Credit Card', 'Personal Loans', 'Online Banking' — whereas visits 1–4 show 'Credit Card', 'Online Banking', 'Personal Loans'. This reordering appears across a second Chrome visit and is not isolated to a single browser engine, suggesting a real experiment on the order of the three product category shortcuts.
