What is content freshness?
Content freshness is one of the most underappreciated ranking factors in modern SEO. Google's Query Deserves Freshness (QDF) algorithm actively boosts recently updated pages for time-sensitive queries — and AI assistants like ChatGPT, Perplexity, and Claude show an even stronger preference for current sources when composing answers.
A blog with stale content — articles last updated 18 months ago, year references pointing to
2022, or schema markup missing dateModified
fields — signals to both algorithms and AI crawlers that the site may not be authoritative on
recent developments. This suppresses visibility exactly when informational queries spike.
This tool measures freshness the way search engines do: by checking published and modified dates, scanning article copy for stale year references, validating schema markup, and cross-referencing the Wayback Machine to detect date-bumping — where a "Last Updated" date is changed without substantive content changes.

FAQ
What is a Content Freshness Score?
A Content Freshness Score is a 0-100 metric that summarizes how current and up-to-date your blog content is. It factors in article ages, how often content is updated, the presence of stale year references in the text, and whether structured data includes accurate date signals. A score of 80+ means your content is consistently fresh; below 50 means significant portions of your blog are stale.
How is the score calculated?
The score combines four weighted signals: (1) the proportion of articles updated within the last 12 months, (2) average content age across all articles, (3) presence of stale year references in article copy (e.g., "best tools in 2022" on a page that hasn't been updated), and (4) schema markup completeness. Missing dates are penalized because search engines and AI assistants can't verify freshness without them.
What does date-bumping detection mean?
Date-bumping is when publishers change the "Last Updated" date on an article without making meaningful content changes — a tactic sometimes used to appear fresher to search engines. This tool checks your articles against the Wayback Machine's CDX API to find cases where your claimed update date is significantly later than the last actual change detected. Articles with a 60+ day gap are flagged.
