See Which Pages Are Going Stale

A content freshness checker finds when each page on a site was last updated. ACME.BOT reads the lastmod date on every sitemap URL and color-codes the site by age.

A Freshness Score rates one section of a site from 0 to 100, averaged across its pages. Pages score by age: 100 under 30 days, 75 at 30-90, 50 at 91-180, 25 at 181-365, 0 past a year.

Freshness is the 6th biggest Google ranking factor, and pages updated at least yearly gain 4.6 positions on average. In AI search the effect is stronger: 76% of pages cited by ChatGPT and Perplexity were updated within 30 days.

Yes. Any public sitemap works, so a competitor's domain scans like your own. Their stale sections are where a fresher page can outrank them.

ACME.BOT still maps the structure, pages by section with counts, but the treemap renders gray because age is unknown. Most CMS platforms emit lastmod by default. If yours doesn't, check your sitemap plugin settings.

Each scan reads up to 5,000 URLs, enough for most sitemaps. Larger sites scan partially, and the report shows the total URL count it found.

Screaming Frog exports lastmod to CSV and leaves the section scores and charts for you to build. Ahrefs starts at $99/mo. ACME.BOT is free and returns the treemap and section scores in seconds.

Refresh it, merge it into a stronger page, or drop it. A refresh means new facts, current data, and a structure that matches what people search for now. Google and AI engines reward real updates, not a bumped date.
