GrowthHackers.se: +271% Organic Clicks in 3 Weeks

The Starting Point

GrowthHackers.se, a Stockholm-based AI marketing agency, was running their website on WordPress. It worked, but it was holding them back.

The numbers told the story:

• PageSpeed performance score: 78
• Largest Contentful Paint (LCP): ~3 seconds
• Total Blocking Time (TBT): ~200ms
• Click-through rate: 0.29%
• Limited visibility into AI search engine performance

The site was slow, hard to experiment with, and invisible to the growing wave of AI-powered search engines like Bing Copilot and Google's AI Overviews.

What Cogny Brought to the Table

This wasn't just a redesign project. Cogny was embedded from day one as the data backbone, providing the intelligence layer that turned a migration into a growth engine.

GEO (Generative Engine Optimization)

Cogny tracked how the site appeared across AI-powered search engines, monitoring citation patterns, content structure signals, and visibility in generative results. This gave the team concrete data on what content formats and page structures AI engines preferred to cite.

Result: AI citations increased by +154% via Bing Copilot, with cited pages nearly doubling from 14 to 26 unique pages. The weekly acceleration pattern was clear: 7 to 23 to 31 citations.

SEM Performance Monitoring

Cogny continuously analyzed search engine marketing signals, identifying which keywords drove qualified traffic versus vanity impressions. The platform flagged underperforming queries, spotted cannibalization between organic and paid, and surfaced opportunities where improved page speed and content quality could reduce cost per click.

Result: Click-through rate doubled from 0.29% to 0.66%, a +131% improvement driven by better targeting and faster landing pages.

SEO Signal Analysis

Cogny's automated SEO monitoring tracked Core Web Vitals, crawlability, and indexation in real-time throughout the migration. Every deployment was validated against search performance data, ensuring no rankings were lost in the transition.

Result: Impressions increased by +60%, confirming that the technical improvements translated directly into broader search visibility.

Experiment Tracking & Validation

Every change during the migration was tracked as an experiment in Cogny. Page speed improvements, content restructuring, meta tag updates, and internal linking changes were all measured against baseline metrics. The team could see within hours whether a change moved the needle.

Result: +271% more organic clicks within 3 weeks. Not a gradual improvement. A step change.

The Technical Transformation

The migration from WordPress to Next.js delivered dramatic performance improvements that Cogny tracked in real-time:

But raw performance numbers are just inputs. Cogny connected these technical metrics to business outcomes, showing exactly how each improvement impacted organic traffic, CTR, and AI engine visibility.

The Compounding Effect

What made this case special was the compounding nature of the improvements. Cogny identified that:

1. Faster pages led to better crawling - Google indexed more pages, more frequently
2. Better Core Web Vitals improved rankings - Higher positions across target keywords
3. Improved content structure boosted AI citations - Generative engines cited more pages
4. Higher CTR signals reinforced rankings - Creating a positive feedback loop

Each improvement fed the next. Cogny's role was to make this flywheel visible and actionable, surfacing which changes to prioritize for maximum compound impact.

Key Takeaways

For marketing teams considering a similar move:

• Data-driven migrations outperform gut-feel redesigns. Every change should be measurable.
• GEO is a real channel now. If your analytics platform doesn't track AI engine visibility, you're flying blind.
• SEM and SEO are not separate disciplines anymore. Cogny's cross-channel view revealed opportunities that siloed tools missed.
• Speed is a growth lever, not just a technical metric. The PageSpeed jump from 78 to 97 directly drove a 2x CTR improvement.

Timeline

• Week 0: Cogny baseline analysis of existing WordPress performance
• Week 1-4: Migration with continuous Cogny monitoring and experiment validation
• Week 5-7 (post-launch): +271% clicks, 2x CTR, +154% AI citations confirmed

The entire project, from first commit to verified results, took less than two months. Traditional agency timelines for comparable projects run three to six months, often without the data infrastructure to prove ROI.
