TACT SEO Drives 3.5x Increase in Sessions in 10 Months, Securing Top 10 Rankings for High-Difficulty Keywords

In the reuse industry, the entry of major corporations has led to intensifying competition for web traffic in the second-hand market. As competitors increase, many companies are finding that traditional site updates are no longer sufficient to maintain search rankings, leading to a growing sentiment that "past success stories no longer apply."

Amidst this, the case of AlphaDea, which utilized the SEO tool "TACT SEO" and an in-house support plan to significantly recover search rankings and increase traffic through AI-driven content expansion and fundamental site structure improvements, is gaining attention. Willgate, Inc., the developer of TACT SEO, has released a case study detailing this success.
