bluelabel.jp

The bluelabel.jp domain presents a mixed bag, with a trust score of 50 and a verdict of "Caution Advised". While the domain's status code indicates a successful connection, the response time is sluggish at 2225ms. The use of Gzip compression and a moderate page size of 168KB suggest a decent approach to performance optimization.

The trust score of 50 is a concern, as it indicates a relatively low level of trustworthiness. This is likely due to the domain's use of a free SSL certificate from Let's Encrypt, which is a good start but not a guarantee of security. The lack of DMARC implementation and a moderate SPF record also contribute to the low trust score.

The domain's technology stack is relatively simple, with a single technology identified as WordPress. While this is a popular and widely-used platform, it may not be the most secure or up-to-date option. The use of TLS 1.3 is a positive, as it provides improved security over older versions of TLS.

bluelabel.jp delivers its homepage in 2225ms (server response time), which is considered slow by industry standards. The total page weight is 168 KB, and we detected 336 resource requests loading assets from 2 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 13 CSS files and 8 out of 13 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 bluelabel.jp produces approximately 0.08g 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 168 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for bluelabel.jp. 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.

The domain's infrastructure appears to be straightforward, with a single IP address (210.157.79.154) and a registrar that is not publicly disclosed. The absence of a dedicated mail server and the use of a shared mail server may increase the risk of email-borne attacks.

The homepage of bluelabel.jp contains 364 words of visible text content. This is a moderate amount of content. The page is structured with 62 H2 headings, 0 H3 headings, 0 H4 headings. The page includes 140 images. 140 images (100%) are missing alt text attributes, which is a significant concern for both accessibility and SEO.

Only 0% of images have proper alt text — we recommend adding descriptive alt attributes to all images.

Notable missing features: XML Sitemap and robots.txt. Adding these could improve search engine discoverability and rich result eligibility.

The domain's page size is moderate, with a word count of 364 and a total of 140 images. The title is a mix of Japanese characters and English text, which may not be optimized for search engines. While the page size and image count are not excessive, the lack of clear optimization strategies may hinder the domain's search engine ranking performance.
