Willgate, Inc. (Headquarters: Minato-ku, Tokyo; Representative Director: Riki Kojima; hereinafter "Willgate") has announced the addition and launch of a new "Graph & Chart Creation Feature" for its AI × SEO tool, "TACT SEO".
■ Background and Details of the Feature Release
Point 1: High demand for "visual information" to aid article understanding
Previously, TACT SEO offered an "Image Generation Feature" that allowed users to create thumbnail images and inserted images with a single click. However, many users requested the ability to "create graphs and charts that specifically illustrate numerical data and comparative structures within articles."
This new feature visually represents complex information that is difficult to convey through text alone, promoting intuitive understanding for readers. By increasing the persuasiveness of the information, it facilitates smoother decision-making for readers, ultimately contributing to improved CVR (Conversion Rate).
Point 2: A seamless diagram creation flow that doesn't interrupt writing
With conventional generative AI, users had to go back and forth between tools or meticulously adjust instructions (prompts) to create the intended charts. Because this feature is integrated into TACT SEO's article editing area, the AI automatically analyzes the written content and generates optimal diagrams for the context in about 20 seconds. Colors can also be freely specified to match the media's tone. This seamlessness, which allows designer-level quality to be instantly reflected in articles, elevates both production efficiency and article persuasiveness.
Point 3: Strengthening "originality" to support Google's evaluation (E-E-A-T)
This feature makes it possible to enhance the expertise and originality of content by inserting numerical data and complex concepts as "unique diagrams." In addition to improving engagement, this secures the E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) highly valued by Google, contributing to stable search rankings.
■ Expected Effects
Utilizing this feature is expected to yield the following effects:
Improvement in read-through rates and CVR: Providing visual clarity minimizes bounce rates and encourages conversions.
Reduction in production costs: Time and outsourcing expenses previously required for diagram creation can be significantly cut, enabling a content mass-production system.
Improvement in article authoritativeness: Inserting data-driven diagrams makes the content more likely to be evaluated by Google and AI as "high-quality content" with high expertise and originality.
