Built for SEO professionals, analysts, and teams that rely on factual timelines.
Trusted by professionals who care about accuracy
Supported: .txt, .csv, .xlsx
The Problem
Most websites don't clearly tell you when a page was actually created. When time accuracy matters, assumptions are not enough.
Published Dates Missing
Published dates are often missing, overwritten, or misleading on most websites.
Easy to Manipulate
CMS timestamps are easy to manipulate, making them unreliable for verification.
Tools That Guess
Many tools guess — or silently fail — without providing confidence levels.
Our Approach: Time Facts First
We don't guess. We analyze multiple independent time signals to determine the most reliable creation and update dates available.
