Indexation Research Project
September 2021 – present
Crawl or No Crawl
Indexzilla is the culmination of over three years of intensive research into search engine indexation systems, spearheaded by forensic SEO expert and technology researcher Carolyn Holzman. Through methodical testing, data analysis, and deep technical investigation of how search engines discover and process content, Carolyn identified critical patterns and opportunities in the indexation process.
Starting in December 2025, Crawl or No Crawl reports are now exclusively for the paid customers of Indexzilla’s indexing platform. (An $18/month value added to your subscription.)This is now available exclusively to you.
