From a 70% traffic crash to 245% revenue growth — how we recovered a dental lab from a Google penalty.
What Was Holding Them Back
Puche Dental Labs had built their online presence over several years and relied heavily on organic search for new B2B client acquisition — dental practices ordering custom prosthetics, crowns, and dental appliances.
When Google's core algorithm update hit, their rankings for nearly every revenue-driving keyword collapsed. Traffic dropped 70% in two weeks. The business had unknowingly accumulated hundreds of toxic backlinks from low-quality directory spam, and their product/service pages had thin, duplicated content that failed Google's Helpful Content standards.
By the time they approached us, three months had already passed since the drop — and attempts to recover in-house had made things worse. The disavow file was applied incorrectly, blocking legitimate links alongside toxic ones.
"A core Google algorithm update wiped out 70% of Puche Dental Labs' organic traffic overnight. Revenue from organic channels collapsed. We performed a full technical and content audit, removed toxic backlinks, rebuilt content to E-E-A-T standards, and drove a 245% organic revenue increase within 6 months."
How We Solved It
Full Technical & Link Audit
We started with a complete Screaming Frog crawl paired with Ahrefs backlink analysis. The technical audit identified 89 issues: duplicate content across product pages, missing canonical tags, broken internal links, slow page speed, and improper hreflang implementation.
The backlink audit identified 156 toxic links from link farms, irrelevant foreign directories, and PBN sites. We sent manual outreach removal requests to 43 webmasters and filed a corrected disavow file with Google Search Console for the remainder.
Content Rebuild to E-E-A-T Standards
Every product and service page was rewritten from scratch by a dental industry specialist. Content was expanded from thin 200-300 word descriptions to comprehensive 800-1,500 word pages covering materials, processes, turnaround times, quality standards, and clinical applications.
Author bios were added to all informational content. A 'Why Us' page was created with team credentials, lab certifications, and years of industry experience — direct E-E-A-T signals for Google's quality raters.
Eight new long-form blog articles were written targeting informational keywords in the dental lab space — content that positioned Puche as the authority on dental prosthetics for dental professionals.
Technical Fixes & Schema Implementation
All 89 technical issues were resolved over a 6-week sprint. Core Web Vitals passed across all key pages. Schema markup was implemented for Product, Organization, and FAQ page types.
A proper canonical tag structure was implemented across 200+ product variation pages, consolidating ranking signals to the main product pages instead of splitting authority across duplicates.
