EVIDENCE / 03

Evidence first. Unmanipulated data. Honest attribution.

Every case study is evaluated across comparable duration windows, unwarped axes, and client anonymisation. We separate observed data, implemented actions, diagnostics, attributed outcomes, and unverified hypotheses.

Evidence Standards & Client Anonymisation Protocol
Confidentiality Protocol

Client Anonymisation

Proprietary domain names, client accounts, and confidential URLs are masked with neutral labels (e.g. Website A). Raw metric relationships and time periods remain intact.

Comparable Timeframes

Before-and-after evaluations maintain strict 1:1 duration parity (e.g. 90 days pre vs 90 days post) to prevent seasonal distortion or window manipulation.

Unmanipulated Data

Charts display daily data including natural weekend dips and volatility. Axis baselines are unwarped to avoid exaggerating performance fluctuations.

Clear Attribution

Outcomes are rigorously divided into observed evidence, implemented actions, verified attributions, and unverified external hypotheses.

Crawl Architecture & Canonical Consolidation

Remediating faceted crawl traps, duplicate indexation, and crawl budget dilution across a multi-location commercial service portal.

EXECUTIVE SUMMARY

Website A operated an extensive multi-location directory where dynamic faceted filters generated over 14,000 indexable parameter permutations. Search engine bots were spending more than 40% of crawl activity on duplicate combinations rather than high-value local service hubs. By establishing strict canonical rules, refining robots crawl directives, and restructuring XML sitemaps, redundant URL indexation was eliminated while search visibility for primary regional landing pages strengthened.

Five-Dimension Honest Analysis

To ensure strict intellectual honesty, every case study separates what was directly observed, what was executed, what can reasonably be attributed, and what remains an unverified external factor.

DATA EVIDENCE

Measured performance shifts recorded directly in Search Console, crawl tools, and analytics.

  • 01Google Search Console Index Coverage report showed a reduction from 14,240 parameter URLs in the valid index down to 312 within 8 weeks of deployment.
  • 02Daily organic search clicks increased from a pre-intervention baseline average of 420 to a post-intervention average of 590 over matching 90-day periods.
  • 03Total search impressions grew from 18,500/day to 24,200/day across location service categories.
  • 04Server log analysis recorded a 64% reduction in Googlebot requests directed at query string parameters.
B2B & Professional Advisory·Anonymised B2B Advisory Website (Website B)Anonymised Case Study

Investigating Click Divergence & SERP Volatility

Diagnosing why organic impressions and average rankings remained steady while click-through rates declined following SERP layout changes.

EXECUTIVE SUMMARY

Website B observed a puzzling trend: overall organic impressions grew by 27% and average rankings improved slightly, yet total organic search clicks declined by 9%. Rather than assuming algorithmic penalty, a granular query cluster investigation revealed that Google had rolled out AI Overviews and multi-unit video carousels across 40% of top informational queries. This case study demonstrates how restructuring content for commercial decision-makers and targeting zero-click answer blocks stabilised high-intent conversions.

  • 02Average ranking position remained virtually unchanged (6.4 vs 5.9), demonstrating that visibility loss was not caused by ranking degradation.
  • 03Segmented analysis confirmed that 100% of the click drop occurred on broad informational head terms, while bottom-of-funnel commercial keywords increased click count by 18%.

Content Consolidation & Cannibalisation Remediation

Resolving keyword cannibalisation and index bloat by auditing 84 competing property investment articles and uniting equity into 14 pillar guides.

EXECUTIVE SUMMARY

Website C had amassed over 400 blog posts and property investment guides over 5 years. A comprehensive search audit revealed that multiple overlapping articles were ranking interchangeably for identical search queries on pages 2 and 3 of Google, splitting internal link equity and confusing search engines. By pruning obsolete content, consolidating 84 fragmented pieces into 14 authoritative pillars, and implementing 301 redirects, primary target terms achieved unified Page 1 rankings.
