ONIMARU creates a copy of the target site and performs fully automatic optimization using AI.
Since the optimized site is created on a different domain from the target site, items that depend on the domain may not display correctly, or some resources may not be acquired, resulting in display corruption.
Also, if the target site uses a cache such as CDN, or if the load on ONIMARU's servers temporarily increases, the performance score may not improve.
KUSANAGI Premium Edition developer licenses allow you to test the effectiveness and customize your AI optimization strategy for free in advance.

If the speed index on the right side is low, the server may have many issues, and if the rendering index on the left side is low, the server may have many issues with resources and rendering, such as images.
The following is a summary of countermeasures for items that are often mentioned as improvement items. The key to speeding up the process is to make it lightweight and to delay loading items that are not necessary for the first view.
Delivery of images in generational format
Convert images to next-generation formats represented by WebP to reduce weight. Different browsers support different formats, so it is necessary to serve them appropriately.
Appropriately sized images
Are thumbnail images and other images being reduced in size using CSS? Deliver images in appropriate sizes to reduce loading time and data volume.
Delayed loading of off-screen images
Delay loading images that are not displayed in the first view.
Exclude resources that interfere with the rendering
Let CSS and JavaScript that are not necessary for first view display load lazily.
Leave the speeding up to AI!
It is very difficult to constantly implement all the measures listed in the improvement items for every page.
WEXAL® Page Speed Technology, a web acceleration engine, and David, a strategic AI, automatically perform optimal acceleration for each page, allowing you to focus on content and measures.
About WEXAL
Focus on Core Web Vitals
Core Web Vitals have been added to the search ranking index since June 2021.
Since Core Web Vitals is also a measure of web user experience, responding to it will lead to improved user experience, and improved user experience will lead to improved conversions, such as PV and turnover.
Therefore, this is an important change that is "directly related to revenue," especially for sites that generate revenue through media and advertising.
