1. Executive Summary & Overview

Simisso (simisso.com) is the digital e-commerce venture of Sevinç Tuhafiye, the largest wholesale haberdashery, knitting yarn, and sewing crafts distributor in the Black Sea region with over 40 years of commercial heritage. Launched in 2017 to modernize traditional wholesale distribution, Simisso offers over 30,000 unique craft SKUs (expanding to over 100,000 variants) spanning knitting yarns, textile accessories, haberdashery, and hobby craft materials.

Simisso partnered with Zeo to overcome ready-made e-commerce platform constraints, restructure its massive category taxonomy, and capitalize on high-intent craft search demand. The collaboration achieved a +259% increase in SEO visibility score and a +111% growth in traffic-generating keywords, establishing Simisso as Turkey's undisputed digital haberdashery leader.

2. Challenge & Market Context

Niche wholesale and craft e-commerce presents unique architectural and inventory challenges:

Ready-Made SaaS E-Commerce Limitations: Relying on a turnkey e-commerce SaaS architecture restricted custom server-side optimizations and advanced technical SEO modifications.
Massive Multi-Variant Taxonomy Bloat: Managing 100,000+ SKU variants (yarn weights, color codes, needle sizes) caused keyword dilution and indexing confusion across product pages.
Under-Optimized Category Hierarchies: Initial category structures lacked semantic granularity, preventing high-intent craft searches ("alize örgü ipi", "dikiş makinesi iğnesi", "tuhafiye malzemeleri") from reaching targeted landing pages.
Unaddressed High-Volume Search Demand: Extensive consumer search demand existed for crafting supplies that Simisso carried in wholesale inventory but had not properly merchandised on web landing pages.

The strategic roadmap defined actionable commercial and search targets:

Category Restructuring & Expansion: Build an intuitive, search-optimized category tree covering all major yarn brands, crafting tools, and textile accessories.
SEO Visibility Acceleration: Achieve a minimum +200% increase in overall search engine visibility score across hobby and craft verticals.
Traffic-Driving Keyword Growth: Expand the active portfolio of non-brand ranking keywords by over +100%.
Product Demand Gap Capitalization: Identify high-volume search queries for unlisted inventory and rapidly merchandise dedicated commercial hubs.

4. Strategy & Innovation
