booksbunker.com Trust Score & Safety Analysis

🤖 AI Summary
After conducting a thorough safety and legitimacy analysis, booksbunker.com receives a trust score of 56/100, which places it in the "Caution Advised" 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 and SPF (Sender Policy Framework) email authentication preventing email spoofing. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), missing Referrer-Policy, potentially leaking URL information to third parties, the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity, and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked booksbunker.com 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.

booksbunker.com Performance, Speed & Core Web Vitals

🤖 AI Summary
booksbunker.com delivers its homepage in 25976ms (server response time), which is considered slow by industry standards. The total page weight is 44 KB, and we detected 73 resource requests loading assets from 0 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 10 CSS files and 5 out of 7 JavaScript files are minified. Minifying the remaining 12 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 booksbunker.com produces approximately 0.02g 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 44 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for booksbunker.com. 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.

booksbunker.com DNS Records, Email Authentication & Domain Registration

🤖 AI Summary
booksbunker.com resolves to the IPv4 address 37.9.175.197 and also supports IPv6 (2a00:4b40:aaaa:2009::5), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 3 name servers: ns1.websupport.sk, ns2.websupport.sk, and ns3.websupport.sk. 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 booksbunker.com is handled by websupport.sk with 2 MX records configured: mx10.websupport.sk and mx20.websupport.sk. 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 is not configured, leaving the domain vulnerable to email spoofing and phishing attacks that impersonate this domain. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is not enabled for booksbunker.com. While not critical for most websites, DNSSEC adds an important security layer by ensuring DNS responses haven't been tampered with during transit. Enabling DNSSEC is recommended for domains handling sensitive data or financial transactions. Our subdomain enumeration scan discovered 25 active subdomains for booksbunker.com: admin.booksbunker.com, api.booksbunker.com, app.booksbunker.com, apps.booksbunker.com, blog.booksbunker.com, cdn.booksbunker.com, community.booksbunker.com, and dev.booksbunker.com. Plus 17 additional subdomains. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

booksbunker.com SEO Analysis, Meta Tags & Open Graph

🤖 AI Summary
The title tag for booksbunker.com is good at 17 characters: "booksbunker.com -". The length is acceptable, though it may be slightly truncated in some search result displays. No meta description is configured for booksbunker.com. This is a critical SEO oversight — without a meta description, Google will auto-generate a snippet from page content, which may not accurately represent the page or entice users to click. Adding a unique, compelling meta description of 120-155 characters is strongly recommended. The canonical url is correctly set to https://booksbunker.com/, preventing duplicate content issues, the page language is declared as sk-sk, and the meta robots directive is set to index, follow, max-image-preview:large, max-snippet:-1, max-video-preview:-1. Open Graph meta tags are configured with 2/4 recommended fields: OG title ("booksbunker.com..."), OG type (website). These tags control how the page appears when shared on Facebook, LinkedIn, and other social media platforms that support the Open Graph protocol. A Twitter Card of type summary_large_image is configured, which controls how links appear when shared on Twitter/X. The "summary_large_image" type displays a large image preview, which typically generates higher engagement rates than the basic card type. The site implements Schema.org structured data with the following types: BreadcrumbList, CollectionPage, EntryPoint, ImageObject, ListItem, Organization, PropertyValueSpecification, SearchAction, and WebSite. Structured data helps search engines understand the page content and can enable rich results (featured snippets, knowledge panels, star ratings) in Google search results, which can significantly increase click-through rates.
