API Sources & Independent Tests

This audit relies heavily on the following APIs. You can run these tests separately here:

Rating Categories

Efficient: Performance & Resources

The Efficient category evaluates how fast and resource-friendly a website works. A high score signals short loading times and a clean technical foundation.

The sub-score is primarily based on Lighthouse metrics for Performance and Best Practices. Additionally, relative benchmarking is performed: transferred data volume and the number of server requests are put in relation to current average values from the HTTP Archive database. This accurately measures how efficiently the site performs compared to global web standards.

Lower CPU load is a side effect — the direct benefit is a better experience for every visitor.

Performance

The Performance score evaluates the speed at which content is loaded and becomes interactive. It analyzes metrics such as the Largest Contentful Paint (LCP) and responsiveness. High performance saves time and reduces battery and CPU load on the user's device.

ECOS Score Display61Performance

Best Practices

This indicator checks compliance with modern web standards. This includes security aspects, correct image formats, and the avoidance of outdated technologies. Following best practices is the foundation for an efficient and maintainable web architecture.

ECOS Score Display100Best Practices

Data Transfer

Here, the data load is evaluated in comparison to the global average (HTTP Archive). The total size of transferred bytes and the number of server requests are measured. Less data traffic means less energy consumption and faster loading times worldwide.

ECOS Score Display62Network

Number of Requests

Every requested file creates communication overhead between the browser and the server. We put the total number of requests in relation to the median of the HTTP Archive database. Fewer requests mean less overhead and a faster-loading page, especially on slow or unstable connections.

Transferred Data Volume

The total size of the website in kilobytes is measured. This value is compared with average values from millions of websites (HTTP Archive). A low data load saves bandwidth for the user and reduces the energy required for global data transfer.

Clean: Ecological Footprint

The Clean area measures the ecological sustainability of digital operations. The focus is on the CO2 balance resulting from hosting and data transfer.

The calculation is performed using the co2.js library and considers two essential factors: the estimated energy consumption per page view and the share of renewable energy in the power grid of the respective server location (Grid Intensity).

A high score shows that the website is operated with minimal CO2 emissions and relies on environmentally friendly infrastructure. This makes the hidden environmental impact of digital products visible and measurable.

Open: Accessibility and Discoverability

The Open category evaluates how accessible and discoverable a website is for both humans and machines. Transparent structures and open standards are the decisive criteria here.

The score consists of two central Lighthouse audits: Accessibility and SEO. A high value guarantees that content is fully usable for people with disabilities and that technical hurdles do not hinder visibility in search engines.

This supports an inclusive web where content is equally accessible to all users and technologies.

Accessibility

This score indicates how usable a website is for people with disabilities. Aspects such as contrast ratios, screen reader compatibility, and logical structures are evaluated. An accessible web excludes no one through technical barriers.

ECOS Score Display80Accessible

SEO

The SEO score checks technical discoverability by search engines. It ensures that content can be correctly indexed and that metadata is present. Good SEO makes information findable for the people who are looking for it.

ECOS Score Display91SEO

Safe

The Safe score evaluates the technical integrity and reputation of a website. It combines infrastructure checks from AbuseIPDB and Google Web Risk with a security header audit from the MDN HTTP Observatory. This covers both the server's reputation and the implementation of modern encryption and protection standards.

Trust & Reputation

The integrity of the domain is checked against global databases such as Google Webrisk and AbuseIPDB. This ensures that the site is not known for malware, phishing, or fraudulent activities. This forms the essential basis for digital trust.

ECOS Score Display100Trust

Google Web Risk

This indicator matches the URL against Google's lists of dangerous web resources. It checks whether the site is known for phishing, social engineering, or the distribution of malware. A clean result confirms that visitors are not exposed to malicious content.

ECOS Score Display100Webrisk

AbuseIPDB Check

Here, the reputation of the server IP is checked. AbuseIPDB collects reports on malicious activities such as spam or DDoS attacks. A clean score confirms that the website's hosting environment is not associated with criminal activities.

Mozilla HTTP Observatory

The MDN HTTP Observatory is an analysis tool by Mozilla designed to evaluate a website's security header configuration. It helps developers correctly implement modern security standards like CSP, HSTS, and CORS to mitigate risks such as cross-site scripting and clickjacking. (HTTP Observatory Scoring Methodology)

Embed Your Audit Badge

Customize your badge below, then copy and paste the generated code into your website.

Color Theme

How "System" mode works: The badge automatically matches your website's styling. It first looks for popular dark/light CSS classes (like .dark or .light-theme) on your page. If none are found, it adapts based on the user's system preferences via CSS media queries.

Code Format

Note: The HTML format fits most use cases, including WordPress, Wix, and standard HTML pages. Choose React if you are pasting the code directly into a React component's JSX.
