The detected stack includes WordPress 7.0, WooCommerce, Google Tag Manager, Cloudflare Turnstile, Cloudflare, YouTube Embed, jQuery, Font Awesome, and WP Rocket. The primary e-commerce platform is WooCommerce. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, erdi.nl receives an overall trust score of 86/100, classified as "Very Likely Safe".

After conducting a thorough safety and legitimacy analysis, erdi.nl receives a trust score of 86/100, which places it in the "Very Likely Safe" category. This score is calculated by evaluating multiple factors including SSL certificate validity, domain registration history, email authentication protocols, security header configuration, and blacklist status across major threat intelligence databases. The analysis identified several positive trust signals: a valid HTTPS connection protecting data in transit, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, a valid SSL certificate issued by Sectigo Limited with 46 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a reject policy — the strongest available setting, DKIM (DomainKeys Identified Mail) providing cryptographic email verification, DNSSEC providing authenticated DNS responses, and a well-established domain registered for over 27.7 years, indicating long-term commitment and legitimacy. Areas of concern include: the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked erdi.nl against 8 major blacklist databases including Google Safe Browsing, Phishtank, Urlhaus, Openphish, Dnsfilter, Spamhaus Dbl, Surbl, and Virustotal. The domain passed all 8 checks with a clean status, meaning it has not been flagged for phishing, malware distribution, spam, or other malicious activities by any of the tested threat intelligence providers. The domain is registered through Metaregistrar B.V. based in NL, with a registration date of 1998-10-26.

erdi.nl delivers its homepage in 74819ms (server response time), which is considered slow by industry standards. The total page weight is 189 KB, and we detected 466 resource requests loading assets from 8 third-party domains. A high number of third-party domains can significantly impact page load time due to additional DNS lookups and TLS handshakes required for each domain. The website uses Gzip compression for text-based assets, achieving an estimated 60.0% reduction in transfer size. This reduces bandwidth usage and improves page load times, especially for visitors on slower connections. Asset minification status: 0 out of 11 CSS files and 23 out of 30 JavaScript files are minified. Minifying the remaining 18 unminified file(s) could further reduce page weight by 10-30% for those assets. Minification is a best practice that reduces download sizes without affecting functionality. From an environmental perspective, each page view of erdi.nl produces approximately 0.09g of CO₂, earning a carbon rating of A. This places the website among the cleanest on the web, demonstrating efficient use of server resources and optimized content delivery. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 189 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for erdi.nl. This typically means the site doesn't have enough real-world Chrome user traffic to generate statistically significant field data, or the domain is not included in the CrUX dataset. Core Web Vitals (LCP, INP, CLS) are important Google ranking factors that measure real user experience.

erdi.nl resolves to the IPv4 address 185.95.45.37, but does not support IPv6. IPv6 adoption is increasingly important as IPv4 address space becomes exhausted, and some ISPs and regions are transitioning to IPv6-only connectivity. The domain has 1 A record(s) configured. The domain name system is managed by 3 name servers: ns1.yourdomainprovider.net, ns2.yourdomainprovider.net, and ns3.yourdomainprovider.net. Having 3 name servers provides good redundancy — if one fails, the others can continue serving DNS queries. The choice of name servers often indicates the DNS hosting provider or CDN service being used. Email for erdi.nl is handled by Microsoft 365 with 1 MX records configured: erdi-nl.mail.protection.outlook.com. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. SPF (Sender Policy Framework) is configured, which specifies which mail servers are authorized to send email on behalf of this domain. This helps prevent email spoofing and improves email deliverability. DMARC (Domain-based Message Authentication, Reporting and Conformance) is configured with a reject policy — the strongest setting, instructing receiving servers to reject unauthorized emails entirely. DKIM (DomainKeys Identified Mail) is configured, adding a cryptographic signature to outgoing emails that receiving servers can verify to confirm the email hasn't been tampered with in transit. DNSSEC is enabled for erdi.nl, providing an additional layer of security by cryptographically signing DNS records. This prevents DNS cache poisoning and man-in-the-middle attacks that could redirect visitors to malicious websites. The domain is registered through Metaregistrar B.V. (NL). It was first registered on 1998-10-26, making it 27.7 years old. Our subdomain enumeration scan discovered 6 active subdomains for erdi.nl: ftp.erdi.nl, mail.erdi.nl, smtp.erdi.nl, staging.erdi.nl, webmail.erdi.nl, and www.erdi.nl. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The homepage of erdi.nl contains 1,728 words of visible text content. This is a substantial amount of content that provides good opportunities for search engine indexing. The page is structured with 4 H2 headings, 1 H3 headings, 2 H4 headings, 4 H5, and 0 H6 headings. The page includes 94 images. 64 images (68%) are missing alt text attributes, which is a significant concern for both accessibility and SEO. Screen readers rely on alt text to describe images to visually impaired users, and search engines use alt text to understand image content. Only 32% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 269 internal links pointing to other pages on the same domain and 6 external links pointing to third-party websites. The high number of internal links suggests a well-interconnected site structure, which helps search engines discover and crawl all pages efficiently. There are 30 external JavaScript files, 11 CSS stylesheets, and 2 iframes on the page. Notable missing features: XML Sitemap, robots.txt, and Schema.org structured data. Adding these could improve search engine discoverability and rich result eligibility. The website has social media presence across 5 platforms: Facebook (@ErdiBV), Twitter (@erdibv), Instagram (@erdi_straatmeubilair), Linkedin (@erdi-straatmeubilair-verkeerstechniek-&-wegbebakening), and Pinterest (@erdibv).
