Crawl Budget Recovery, Render Remediation & Indexation Defence.

For enterprise sites with six-figure URL sets. We parse server logs, diagnose JS render decay, and eliminate the crawl waste, canonical drift, and indexation bleed that quietly erode commercial-keyword rankings and inflate paid acquisition cost.

Core Value

Your site is infrastructure — instrumented, profiled, and engineered to protect revenue-generating URLs from crawl decay, render regressions, and Core Update volatility.

Strategic Features

Built on verifiable execution.

Core Web Vitals Remediation

LCP, INP, and CLS regressions traced to server response, render-blocking resources, and layout instability — remediated at the edge with ticketed dev-ready fixes.

Server Log-File Analysis

Parse hundreds of millions of log lines to map exactly how Googlebot spends your crawl budget — reallocating it from parameter noise to revenue-generating templates.

Schema Markup Deployment

Custom JSON-LD — product, article, FAQ, breadcrumb, organisation — engineered for rich result eligibility on commercial-intent queries at scale.

JS Framework Render Diagnostics

Render decay traced across React, Next, Angular, and Vue apps. Hydration, SSR, and dynamic rendering decisions made on data — not framework defaults.

Canonical & Faceted Navigation Fixes

Canonicalisation, parameter handling, and faceted navigation solved at the code layer — not brittle noindex bandaids that leak equity across templates.

Indexation Forensics

Detect orphan pages, soft-404s, duplicate canonicals, and stale indexed URLs that leak authority and dilute commercial-keyword ranking signals.

Execution Framework

How we deliver, end to end.

01 — Diagnose

Deep Technical Audit

Full crawl, log parse, render trace, and CWV profile — every bottleneck surfaced with pipeline-value-weighted prioritisation.

02 — Engineer

Ticketed Remediation Roadmap

Dev-ready tickets with code samples, acceptance criteria, and QA checklists your engineering team can ship without translation overhead.

03 — Verify

Regression Monitoring

Automated CWV, crawl-stat, and indexation regression checks — protecting deployed gains against release-cycle decay.
