Hiring an SEO company in London is a significant investment. Whether you're onboarding a new agency or evaluating your current provider, you deserve full transparency into what is being done, why, and how results are measured.
Too many businesses settle for vague monthly reports filled with vanity metrics. In 2026, the technical landscape has evolved dramatically: AI-driven search, entity-based indexing, Core Web Vitals v3, and passage-level ranking demand a new standard of accountability from any SEO agency you trust with your digital presence. A credible partner should demonstrate a transparent set of core capabilities that go far beyond keyword tracking.
A 2025 survey by the Chartered Institute of Marketing found that 62% of UK businesses felt they lacked sufficient visibility into their SEO provider's actual activities. An audit isn't adversarial — it's good governance.
Can You Show Me the Full Crawl Health Report?
Any credible SEO company in London should run regular site crawls using Screaming Frog, Sitebulb, or Lumar. Ask for raw data — not a summarised slide deck.
Look for: HTTP status code distribution, orphaned pages, redirect chain identification, canonical tag conflicts, and hreflang accuracy.
Red flag: If your agency cannot produce a crawl report on demand, they may not be monitoring your site's technical health at all.
How Are You Tracking Core Web Vitals v3?
The introduction of Interaction to Next Paint (INP) as a stable metric means performance optimisation is no longer optional.
Ask specifically: Are they using field data (CrUX) or only lab data (Lighthouse)? Which pages fail thresholds? Have they coordinated with your dev team on render-blocking resources?
What Is Your Approach to Entity-Based SEO?
Google's understanding of entities is central to how content is ranked and surfaced in AI-generated answers.
Demand details on: Schema markup (JSON-LD), Knowledge Graph alignment, use of sameAs, about, and mentions properties, and whether they're optimising for SGE.
Can You Provide a Backlink Audit With Risk Scoring?
Ask for domain-level risk scoring, anchor text distribution analysis, identification of toxic referring domains, and a disavow file with rationale.
Red flag: If the agency built links but cannot tell you where they are or how they were acquired, proceed with extreme caution.
How Do You Measure Organic Revenue Attribution?
Traffic is meaningless without commercial context. Ask about GA4 attribution modelling, CRM integration, assisted conversion tracking, and segmentation by landing page, device, and geographic market.
What Log File Analysis Have You Conducted?
Server log files reveal how Googlebot actually interacts with your site. Key insights include crawl frequency per directory, ignored pages, sitemap vs. crawl discrepancies, and crawl trap identification.
How Are You Adapting for AI-Powered Search?
With AI Overviews, Bing Copilot, and Perplexity reshaping discovery, your agency must monitor AI-generated answer visibility, content citation probability, zero-click strategy, and LLMO frameworks.
Can You Walk Me Through Your Content Decay Analysis?
Content doesn't last forever. Expect a content decay dashboard with 90-day windows, a refresh schedule, historical comparisons, and cannibalisation detection.
What Is Your Internal Quality Assurance Process?
Ask about peer review processes, staging environment testing, rollback procedures, and change logs documenting every modification made to your site.
How Granular Is Your Reporting?
The depth and frequency of reporting reflects the seriousness of account management. Demand granular, frequent, transparent reporting that goes beyond vanity metrics.

How to Conduct Your Audit
Practical Audit Framework
Request Raw Data Access
Never accept pre-filtered reports. Ask for GSC, GA4, and all third-party tool access.
Cross-Reference Claims Against Data
Verify ranking claims against Search Console performance reports.
Benchmark Against Industry Standards
Use CrUX data, HTTP Archive reports, and Ahrefs studies for context.
Evaluate Communication Quality
Can your account manager explain complex concepts clearly and proactively flag risks?
Score and Decide
Rate across all ten questions on a 1-10 scale. Below 5 on more than three = time for a serious conversation.
