Overview
Who this audit is for
- Your Lighthouse scores are poor and you want to know whether your tag stack is a significant contributing factor.
- You have optimised images and CSS but performance is still lagging and you want to understand if third-party scripts are the cause.
- A client, stakeholder, or SEO team has flagged Core Web Vitals as a concern and you want a quick baseline before investing in deeper work.
- You are about to add more marketing tags and want to understand the current performance baseline first.
- You are considering the paid Website Technical Performance Audit and want to see what a surface review finds first.
What the Website Performance Audit covers
- Core Web Vitals measured via Lighthouse on up to 3 representative page templates: LCP, INP, and CLS on desktop and mobile.
- A basic assessment of which third-party tags appear to have the highest performance cost based on the Lighthouse report.
- Identification of obvious tag loading issues: synchronous scripts in the head, render-blocking requests, or large third-party payloads.
- The top tag-related performance improvements most likely to move your Core Web Vitals scores.
What you receive
- A written performance summary with your current Core Web Vitals scores on desktop and mobile.
- The top tag-related performance issues identified and why they matter.
- A recommended next step for the most impactful findings.
Scope and timing
- 1-2 hours of review time, completely free.
- Up to 3 representative page templates in scope, confirmed on the scoping call.
- Lighthouse-based testing, not lab measurement under controlled network conditions. Results are directional, not definitive.
- Findings delivered in writing. This is not the same as the paid audit, which measures each tag's individual performance cost.
What makes this audit different
- We are clear about what Lighthouse-based testing can and cannot tell you versus controlled lab measurement.
- We focus on the tag stack specifically, not general web performance advice available from any Lighthouse report.
- If your tag stack does not appear to be the primary cause of your performance issues, we say so rather than overstating the findings.
- No requirement to book a follow-up call to receive the results.

Frequently Asked Questions
How is this different from the paid Website Technical Performance Audit?
The free audit is a Lighthouse-based snapshot covering the most visible issues on up to 3 pages. The paid audit measures each tag's individual contribution to LCP, INP, and CLS under controlled network conditions across 5-10 page templates, with expected gains stated per recommendation.
Is Lighthouse enough to understand my performance problems?
Lighthouse gives a reliable directional signal for LCP and CLS. INP is harder to measure via Lighthouse and is more accurately assessed with real-user interaction testing. The free audit is a starting point, not a definitive diagnosis.
Which page templates should I suggest?
Your highest-traffic pages and your most commercially important pages, typically homepage, a key product or service page, and a conversion page. We confirm on the scoping call.
Will you test on real devices?
The free audit uses Lighthouse in Chrome DevTools, which simulates mobile conditions. The paid audit includes additional device testing where the issue warrants it.
