1. Executive Summary & Overview

Founded in 2013 and acquired by global fintech leader PayU in 2019, iyzico (iyzico.com) is Turkey's premier payment service provider and financial technology corporation. Offering artificial intelligence-based fraud protection, virtual POS (Sanal POS) checkout solutions, marketplace payment flows, and the consumer-facing "iyzico Buyer Protection" (iyzico Korumalı Alışveriş) ecosystem, iyzico powers secure online payment transactions for hundreds of thousands of merchants and millions of consumers.

iyzico partnered with Zeo on a multi-year technical SEO and developer documentation optimization program, successfully navigating two major site migrations and rebranding phases without ranking loss. The engagement delivered a +43% increase in organic search traffic, a -68% reduction in bounce rate, and secured permanent #1 organic search dominance for "Virtual POS" (Sanal POS).

2. Challenge & Market Context

Fintech payment infrastructure search involves steep technical transitions and intense B2B keyword competition:

High-Risk Website Redesign & Migration Cycles: The platform underwent two major website infrastructure overhauls and UI redesigns, requiring strict URL mapping to prevent organic traffic drops.
Fierce B2B Virtual POS Search Competition: Competing against traditional commercial banks and emerging fintech payment processors for hyper-competitive merchant acquisition queries ("Sanal POS", "online ödeme alma", "pazaryeri ödeme çözümleri").
Dual Audience Search Dynamics: Serving two distinct user personas simultaneously: B2B merchants and developers researching API integrations vs end-consumers seeking buyer protection and refund support.
Technical 4xx URL Hygiene: Rapid product iteration generated broken endpoints that required real-time automated monitoring.
