MediaSeek Inc. operates 'ICONIT Research,' an in-app survey service within its QR/barcode reader app 'ICONIT,' which has surpassed 36 million cumulative downloads.
In recent years, with changes in search results and the proliferation of Generative AI, the evidence supporting information reliability is being emphasized more than ever. This is where 'primary data' is gaining attention. Primary data refers to data collected or verified directly by a company rather than summaries or guesses from others, including survey results, user actual usage data, and verification data.
Primary data enhances the persuasiveness of articles, press releases, and sales materials. It serves as a differentiator for SEO and as a basis likely to be cited in AIO/LLMO (AI Optimization).
ICONIT Research offers survey outsourcing for companies and organizations, handling everything from question design to collection, tabulation, and reporting.
