Mycat Inc. (Headquarters: Meguro-ku, Tokyo) has newly released a "Website Diagnosis Tool" (https://volt-web.dev/tools/site-check) on its AI Web production estimation and ordering platform "VOLT" (https://volt-web.dev).
Demand for "Website Health Checks":
According to the Ministry of Internal Affairs and Communications' "2023 Communications Usage Trend Survey," approximately 90% of companies have websites. However, only a limited number of companies regularly check quality aspects such as site display speed, SEO measures, and accessibility.
Google's Lighthouse is a powerful diagnostic engine, but it requires developer tool operations, making it a high hurdle for those other than web administrators. Many cases exist where companies feel their "site might be slow" but leave it unaddressed without understanding the problem.
Three Features of the "Website Diagnosis Tool":
1. Just enter a URL: No developer tool operations required. Simply paste a URL to start the diagnosis, and results are displayed in tens of seconds.
2. Scores 4 metrics out of 100: Evaluates performance, SEO, accessibility, and best practices based on Google Lighthouse standards. Points for improvement are clear at a glance.
3. Report with improvement tips: Provides not only scores but also specific improvement actions such as "compress images" and "add meta description."
How to Use:
1. Access the VOLT Website Diagnosis Tool (https://volt-web.dev/tools/site-check).
2. Enter the URL of the site you want to diagnose and click "Start Diagnosis."
3. Check the scores for the four metrics (performance, SEO, accessibility, best practices) and improvement suggestions.
Future Development:
VOLT will continue to develop and release tools that support the visualization of site quality and proposals for improvement, aiming to close the information gap in Web utilization for small and medium-sized enterprises.
