oe1.com

We performed a comprehensive analysis of oe1.com on 2026-07-03. The website returned an HTTP 200 status code with a server response time of 11398ms. The page is served over HTTP/1.1 protocol, however no compression (Gzip or Brotli) is enabled, which means the page is transferred at its full uncompressed size. The total page weight is 176 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by WoTrus CA Limited (DV type). The connection is encrypted using TLS 1.3 with the TLS_AES_256_GCM_SHA384 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 3 domain(s) (Subject Alternative Names) and expires on 2026-07-22, which is 19 days from now. The security headers analysis reveals a score of 50/100 (moderate). The following security headers are properly configured: Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options. However, the site is missing Strict-Transport-Security (HSTS), Referrer-Policy, and Permissions-Policy, which could expose the site and its users to cross-site scripting (XSS), clickjacking, and other web-based attacks. Our technology detection scan identified 3 technologies across 3 categories powering oe1.com. The detected stack includes Nuxt.js, Google Analytics 4, and jQuery. The site uses Nuxt.js as its primary framework. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, oe1.com receives an overall trust score of 63/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, oe1.com receives a trust score of 63/100, which places it in the "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 and a valid SSL certificate issued by WoTrus CA Limited with 19 days until expiration. Areas of concern include: 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 oe1.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.

Our technology detection engine scanned oe1.com and identified 3 distinct technologies across 3 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. Framework: Nuxt.js — provides the application framework and routing for oe1.com. Analytics: Google Analytics 4 — tracks visitor behavior and provides traffic insights for oe1.com. JavaScript Library: jQuery — provides utility functions and DOM manipulation for oe1.com. We also extracted the following tracking identifiers: Google Analytics 4 Measurement ID G-GHY3YP4K6Y. These IDs can be used to identify other websites operated by the same organization.

oe1.com delivers its homepage in 11398ms (server response time), which is considered slow by industry standards. The total page weight is 176 KB, and we detected 483 resource requests loading assets from 7 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. No compression is currently enabled on oe1.com. Enabling Brotli or Gzip compression could reduce page size by 60-80% for text-based assets (HTML, CSS, JavaScript), significantly improving load times and reducing bandwidth costs. This is one of the simplest and most impactful performance optimizations available. Asset minification status: 5 out of 5 CSS files and 3 out of 8 JavaScript files are minified. Minifying the remaining 5 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 oe1.com 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 176 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for oe1.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.

oe1.com resolves to the IPv4 address 36.248.208.103, 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 5 A record(s) configured. SPF is not configured, meaning any server could potentially send emails pretending to be from this domain. This is a significant email security concern. 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 oe1.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.

The homepage of oe1.com contains 670 words of visible text content. This is a moderate amount of content. The page is structured with 0 H2 headings, 155 H3 headings, 2 H4 headings. The page includes 77 images. 4 images (5%) 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 95% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 358 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 8 external JavaScript files, 5 CSS stylesheets, and 0 iframes on the page. The site implements the following web standards and features: XML Sitemap (helps search engines discover all pages) and robots.txt (controls search engine crawling behavior). Notable missing features: Schema.org structured data. Adding these could improve search engine discoverability and rich result eligibility.

The title tag for oe1.com is good at 15 characters: "光电查-全球十万光电产品数据库". The length is acceptable, though it may be slightly truncated in some search result displays.
