Introduction

In the ever-evolving landscape of digital marketing, understanding and optimizing your website's SEO (Search Engine Optimization) is crucial for standing out among competitors. On July 13, 2026, Web Writer Pro, a Tokyo-based company, introduced S Check, a groundbreaking and free SEO diagnostic tool designed to evaluate a website's potential for high Google search rankings simply by inputting its URL.

What is S Check?

S Check stands out by offering a comprehensive evaluation based on 80 distinct metrics across ten categories, examining both substantive content quality and technical aspects of SEO. Users do not need specialized knowledge nor registration, making it an accessible option for business owners and web managers looking to understand their site’s current SEO standing.

Key Features of S Check

1. Dual-layer Scoring System

S Check visually presents the foundation of SEO through a dual-layer scoring system, separating the fundamental aspects—like content originality and E-E-A-T (Experience, Expertise, Authority, Trustworthiness)—from technical elements, which include indexing capabilities and crawl design. This differentiation allows users to accurately identify specific areas for improvement.

2. Prioritized Improvement Metrics

The tool scores the diagnosed areas with grades from S to E and offers detailed metrics across 80 parameters. This allows users to see at a glance where their website may be falling short, facilitating targeted optimization efforts.

3. Instant Improvement Code Samples

For any weak areas identified, S Check automatically generates actionable code examples for improvements, covering essentials like robots.txt files, XML sitemaps, structured data (JSON-LD), canonical tags, and meta descriptions. This practical support ensures that users can implement suggested changes efficiently.

Background to the Service

As many site operators struggle with low search ranks and uncertainty regarding the causes, the need for a straightforward and effective solution has become evident. Comprehensive SEO tools can often be expensive and complex, while free options may lack depth.

Given this backdrop, S Check aims to bridge the gap between sophisticated analysis and user-friendliness. Unique to S Check is the ability to pinpoint whether issues lie in content quality or technical execution, making it easier for users to comprehend their site's SEO status.

Differences from Existing Tools

What sets S Check apart from other SEO tools is its focus on delineating problems into essential and technical spheres. This separation is crucial as it allows even non-experts to navigate their website's optimization journey with clarity.

The diagnostic process operates by gathering publicly available HTML, ensuring that there is no need to transmit page contents to external AI services. Leveraging the expertise gained from producing over 30,000 SEO-focused articles, Web Writer Pro has distilled its evaluation criteria into these 80 concise rules.

User Demographics

S Check is designed for business operators and web managers seeking to reassess their website's SEO foundation, irrespective of their CMS platform, be it WordPress, Webflow, or custom development.

Development Goals

The ambition behind S Check is clear: to empower users to harness both strong content creation skills and technical aptitude, thereby fostering better SEO outcomes. As stated by Daichi Fujikura, CEO of Web Writer Pro, “SEO cannot be successful through quality writing or technical adjustments alone; both must be in sync. We created S Check to offer clarity and direction to users.”

FAQs

1. Is S Check really free?

2. What insights will I gain?

3. How does this tool compare to others?
Unlike many other high-functioning tools, S Check specializes in identifying SEO foundations, allowing non-experts to grasp where enhancements are needed.
