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.
Efficiency here not only reduces CPU load but directly improves the user experience.

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 conserves the hardware resources of users.
ECOS Score Display100Performance
Best Practices
This indicator checks compliance with modern web standards. This includes security aspects, correct image formats, and the avoidance of outdated technologies. Clean best practices form the foundation for a long-lasting, efficient, and maintainable web architecture.

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 directly means less energy consumption and faster loading processes worldwide.
ECOS Score Display100Network
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 significantly faster page build, especially with 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 invisible environmental impacts of digital products transparent and evaluable.

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.
Openness thus promotes an inclusive internet and ensures that information remains equally accessible to every user group.

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 inclusive web is an open web that excludes no one through technical barriers.
ECOS Score Display100Accessible
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 openly accessible and visible to the relevant target group on the net.
ECOS Score Display100SEO
Safe
The Safe index evaluates the technical integrity and reputation of a website. It combines infrastructure analysis from AbuseIPDB and Google Web Risk to detect malware or blacklisting with an in-depth audit of HTTP security headers via the MDN HTTP Observatory. This multi-layered approach ensures that both the server's reputation and the implementation of modern encryption and protection standards are verified.

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 negative result guarantees that visitors are protected from 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)
