1. What’s going wrong? Your website is getting traffic. Shoppers are browsing, clicking, even typing into your search bar — but... they leave without buying. You know something’s off. You suspect the problem lies somewhere between “they arrive” and “they convert.” But what exactly? It’s your on-site search. That humble little box is costing you thousands in lost revenue every month. When your search doesn’t return relevant results, misreads keywords, or dead-ends the shopper journey, people bounce. Even worse? High-intent buyers walk away because they can’t find what they’re trying to buy. You’ve tried: Rewriting product descriptions Adding more filters or sorting options Manually fixing PDP tags or meta fields But it’s not scalable. And the problem keeps resurfacing. The reality? Most ecommerce platforms and plugins aren’t optimized for behavior-driven discovery. And your catalog complexity is now working against you. It’s not that you don’t have the product — it’s that your customer can’t find it. 2. Why is this happening? Here’s what’s likely going wrong: Problem #1: Your tagging and product data are inconsistent. If 10 variants of a product are described differently, your search engine gets confused. When your tagging taxonomy lacks rules, search results become chaotic or irrelevant. Problem #2: Your site search engine isn’t trained for your catalog. Tools like Algolia and Unbxd are powerful, but only if configured right. Without synonym mapping, category weightage, and exclusion logic, they act blind. Problem #3: You’re not analyzing what people are actually searching for. Search queries are a goldmine of customer intent — but most brands don’t have dashboards that track, segment, or respond to this data in real time. This isn’t your fault. Most ecommerce teams aren’t trained in on-site behavior diagnostics. But once you connect search patterns to catalog logic and user experience? The payoff is huge. 3. What you probably want? You want a site that sells to people who want to buy. You want: Relevant, smart search results that reflect shopper language Tagging and synonyms that make sense to humans, not just machines A system where site search teaches your team about customer needs You want fewer bounces. More conversions. Higher average order values. And a content/catalog setup that feels like an asset, not a liability. 4. Why Me? I’m Prathyusha Kokku — and I’ve cleaned, optimized, and restructured search + product tagging systems for some of the largest retail platforms in India and MENA. I’ve: Audited and optimized 127,000+ SKUs for search accuracy, leading to a 12% lift in search-to-cart conversion at Lifestyle Rebuilt product tagging hierarchies and set keyword guardrails to standardize content across massive catalogs Implemented synonym enrichment across 40+ apparel and non-apparel categories Built Power BI dashboards tracking top 1,000 queries, null results, and behavior drop-offs Collaborated with teams using Algolia, Unbxd, and GA4 to create a full feedback loop between CX, content, tech, and merch I bring brand logic, behavioral understanding, and analytical precision — not just search engine tech. If it’s not converting, it’s not working. And I fix that. 5. What is the Offer? The Search Conversion Fix A structured search and catalog optimization sprint + ongoing advisory, designed for high-SKU brands losing money from poor discoverability. Who it’s for: Ecommerce/D2C brands with 500+ SKUs Retailers with search engines like Algolia, Unbxd, or default search plugins Businesses seeing high bounce or low conversion post-search Teams with a product/content ops lead who can help implement recommendations Team requirements: 1 product/catalog manager 1 content writer or tagging resource 1 dev or platform admin to implement tech-side changes MVP: Search Performance Diagnostic (2 Weeks) A rapid diagnostic for brands who want clarity, not complexity — perfect if you’re not ready for a full overhaul, but want to stop bleeding sales. You get: Audit of top 250 search queries (volume, exits, nulls) Zero-result report + suggested tagging/content fixes 1 category synonym starter set 3–5 UX recommendations (filters, labels, logic) Lite dashboard (Google Sheet or Power BI snapshot) Time Commitment: 1x 60-min kickoff call 1 async handover after 10 working days Optional 30-min review call OPTION A: Monthly Retainer (3-month minimum) Search Performance Advisor 1x site search + bounce report each month 1 new synonym/category rule update per month Monthly merch/content sync with insights from top queries Quarterly tagging audit + evolution roadmap Time Commitment: 1x 45-min call/month 1–2 hours async collaboration/week
