Performance audit for charging time, core web vitals and technical brakes
Measuring charging problems and understanding their causes
We check which technical causes are slowing down your website – from frontend and asset topics to rendering, caching and core web vitals. The result is a prioritized basis for meaningful optimization.
- Personal care
- Agreed scope of services
Sample order: The page start is fast, the form reacts slowly
Illustrative process · no published customer case. The binding scope is agreed in advance.
What you bring
Reproducible sequence, affected devices and existing measurements or field data.
What we are investigating
We examine selected calls and interactions to distinguish server wait time, resources, main thread work, and presentation issues.
What you continue to work with
A technical report identifies bottlenecks, measurement conditions, priority and verifiable measures for development or hosting.
Performance limits
Laboratory values are snapshots. The audit does not contain a guarantee of certain field data and does not automatically include the implementation of all recommendations.
For whom the service makes sense
- Companies with Slow Websites or Weak Web Lives
- Agencies with performance printing in customer projects
- Teams that want to understand the biggest brakes before optimization
Typical situations
- Performance is bad, but the causes are unclear
- Lighthouse and real user experience do not go together
- Mobile pages or landing pages are too slow
- Relaunch or template change has deteriorated performance
What is included
- Testing of key performance brakes and metrics
- Classification of core web vitals, rendering, assets and technical load
- Prioritisation by impact and effort
- Concrete next steps for optimization
- Optional transition to direct implementation
What they receive
- Prioritized performance finding
- Cause overview of the strongest brakes
- Recommendations for meaningful optimization order
- Basis for direct performance optimization
Expiry date

Why Seitenreport
A performance audit is helpful if not only values, but their causes are presented in an understandable and prioritized manner.
Seitenreport translates raw data into concrete levers with technical plausibility and implementation relevance.
The free main analysis and SEO tools are a good place to start. In the service, we take over classification, prioritization, action logic and, depending on the project, the concrete correction or implementation support.
Next step
Briefly describe starting position, affected pages or page types, CMS/Setup and destination. This allows you to quickly assess whether audit, optimization, troubleshooting or support is the most sensible next step.
What you can do concretely
- Measurement of representative pages and relevant page types
- Classification of PageSpeed and available core web hospitals data
- Prioritized list of causes for images, resources and page delivery
The binding scope is in the individual offer. Subsequent implementation or ongoing monitoring can be agreed separately.
What we vote before the start
The entry offer includes the investigation, no implementation. Data accesses and additional URL groups are coordinated in advance. For a broad inventory, the 360° expert analysis fits.
FAQ
Is this only for Core Web Vitals?+
No. Core Web Vitals are an important part, but a performance audit looks at the technical causes overall.
What is the difference with performance optimization?+
The audit evaluates and prioritizes. The optimization then implements the relevant improvements or accompanies them.
Does this also make sense for individual sides?+
Yes. Especially for critical landing pages or page types, this can be very helpful.
