Technical SEO Recovery and Traffic Restoration After CMS Migration

Case Study: Technical SEO Recovery and Traffic Restoration After CMS Migration

1. Project Overview

Niche: E-commerce (Electronics Online Store).
Pre-launch status: The client approached us in a crisis situation. Following a migration to a new platform (CMS), organic traffic had plummeted by over 50%. The website was rapidly losing rankings across key categories, leading to a sharp decline in online sales.

2. Identified Issues Post-Migration

A comprehensive technical audit revealed critical errors made during the site transfer:

1. URL Structure Breakdown.
The new CMS altered page addresses, while old URLs returned 404 errors. Consequently, search engines were dropping the old pages from their index.

• • Problem: loss of indexed pages and link equity.

2. Meta-data Loss.
Previously optimized Titles and Descriptions were not transferred, rendering the search snippets irrelevant.

• • Problem: decreased CTR and weakened relevance signals.

3. Duplicate Content.
The new platform generated numerous technical duplicates, cluttering the index and diluting link equity.

• • Problem: wasted crawl budget and diluted ranking potential.

3. Goals and Objectives

• Restoration: Return traffic and ranking metrics to pre-migration levels.
• Indexing: Ensure search engine bots correctly crawl the new site structure.
• Growth: Exceed pre-crisis performance by fixing structural flaws within the new CMS.

4. Implementation: Step-by-Step

Step 1: Restoring Connections (301 Redirects)

The most vital step was preserving the link equity of the old pages. We prepared and implemented a massive redirection map:

• Redirection mapping: mapped over 10,000 old URLs to their corresponding new addresses.
• Implementation: set up page-by-page 301 redirects to guide users and search bots to the current pages while retaining the site’s accumulated authority.

Step 2: Optimizing Crawl and Indexing

We eliminated the technical «noise» generated by the new system:

• Robots & sitemap: revised robots.txt and sitemap.xml files, specifying priority paths for indexing.
• Canonicalization: configured canonical tags for filter and pagination pages to prevent indexing of duplicate content.
• Faster recrawling: accelerated site re-crawling using the URL Inspection tool in Google Search Console.

Step 3: Meta-data Regeneration

To restore page relevance in search results, we focused on tag optimization:

• Mass restoration: restored Titles and Descriptions for categories and product cards en masse, based on an analysis of cached site versions.
• Automation for new products: implemented automated meta-tag generation templates for new products, incorporating specific attributes (model, brand, SKU).

5. Final Results

Thanks to prompt action, the decline was halted and then fully reversed:

6. Verification Tools

• Google Search Console: a performance graph featuring a distinct V-shaped curve (sharp drop followed by steady recovery).
• Topvisor: a website visibility and average position chart confirming the keywords’ return to the TOP rankings.
