Website Performance Monitoring and Core Web Vitals

Managed synthetic and real user monitoring, Core Web Vitals history, Lighthouse audits, performance alerts, and deployment regression analysis. Plans from $45/month.

THE CHALLENGE

Why this work matters

A single PageSpeed score cannot show when a release slowed your site or which visitors are affected. Continuous measurements connect changes in loading, responsiveness, layout stability, scripts, and third-party resources to a timeline your team can investigate.

EXPECTED OUTCOMES

What the engagement is designed to achieve

  • A historical baseline for LCP, INP, CLS, and page performance
  • Alerts against agreed performance budgets with accountable owners
  • Before-and-after evidence for releases and optimization work
  • Prioritized findings tied to user experience and affected pages
DELIVERABLES

What your team receives

  • Synthetic browser checks for agreed URLs, device profiles, and locations
  • Real User Monitoring setup with web-vitals, sampling, and privacy review
  • Core Web Vitals trends: LCP, INP, and CLS with field and lab data separated
  • Lighthouse performance audits and resource waterfall analysis
  • Regression comparisons annotated with deployment events
  • JavaScript error and script-impact diagnostics within the agreed scope
  • Third-party resource analysis for ads, analytics, and external scripts
  • Competitive benchmarks using comparable public-page test conditions
  • Performance budgets and alert routing
  • CI/CD checks and reporting integration where agreed

DELIVERY PROCESS

From defined scope to validated handover

  1. 01

    Define coverage

    Agree URLs, test frequency, devices, locations, RUM traffic allowance, retention, alert recipients, and success criteria.

  2. 02

    Install and baseline

    Configure synthetic checks and an approved RUM snippet. Separate field metrics from lab results and establish the initial baseline.

  3. 03

    Monitor and investigate

    Review trends, budgets, script impact, and release changes. Escalate findings through the agreed alert channel.

  4. 04

    Optimize and verify

    Prioritize improvements and compare measurements after changes. Implementation work and additional integrations are scoped separately.

QUESTIONS & ANSWERS

Common questions about web performance monitoring

How much does the service cost?

Starter begins at $45 USD per month and Growth at $288 USD per month. Enterprise is quoted individually. These starting prices are 50% below the published SpeedCurve Starter ($90) and Growth ($576) starting prices checked on October 9, 2026; this is a price comparison, not a claim of identical allowances or features. Taxes, setup, infrastructure, and additional implementation are confirmed in the proposal. URLs, test frequency, RUM volume, retention, and support determine the final price.

Is this a self-service SaaS dashboard?

This page offers a managed service with onboarding by consultation. It does not provide an instant monitoring account, checkout, or a live customer dashboard. Collection, access, reports, and integrations are configured after the scope is accepted.

How are synthetic monitoring and RUM different?

Synthetic tests repeat a controlled browser journey and help reproduce changes. RUM records supported performance metrics from actual visitors and reflects their devices and networks. Synthetic Lighthouse tests do not measure field INP; field and lab results are reported separately.

What access does Real User Monitoring require?

RUM requires approval to install a collection snippet on your website. We agree sampling, collected fields, retention, consent requirements, and access controls before installation; personal data collection is not assumed.

Does monitoring include unlimited optimization or guarantee good Core Web Vitals?

No. Monitoring provides evidence and recommendations. Remediation, custom development, support response times, and test capacity are bounded by the agreed scope. Results depend on the application, traffic, hosting, and third-party resources.
