# Recovered a 38% traffic drop after a botched JS migration

*Client: B2B SaaS Platform · Industry: SaaS · Region: Singapore · Duration: 2 weeks intensive + 30 days monitoring*

> A SaaS company's React rewrite tanked their organic traffic overnight. We diagnosed and fixed the indexation collapse in 14 days.

## Metrics

- **Traffic recovery:** +47%
- **Pages reindexed:** 1,840
- **Time to fix:** 14 days
- **Lost MRR recovered:** $22k

## Problem

After migrating to a SPA, organic traffic fell 38% in 3 weeks. Engineering didn't know why and panic was setting in.

## Strategy

- Ran log file analysis — Googlebot was hitting 1.8k pages but rendering empty content.
- Implemented SSR on all indexable routes and fixed canonical/hreflang issues.
- Added structured data + breadcrumbs to recover rich results.
- Submitted updated sitemap and monitored re-indexation daily.

## Result

Traffic recovered above pre-migration levels in 6 weeks. The team now has a pre-deploy SEO checklist that prevents this class of bug forever.
