Who Moved in September: A Monthly Sitemap Activity Read

Data filtered to URLs with a lastmod date from September 1 through October 2, 2026, from 10,459 tracked URLs across eight sites.

Two caveats matter. lastmod measures detected page activity, which can include publishing, rewriting, migration, template changes or sitemap updates. And absence of activity in the supplied file is not proof that a company has stopped publishing.

Activity overview

Raw counts are misleading this month. Skyline's 1,695 and Exhibit Experience's 173 are mostly single-day batch refreshes (Sept 30 and Sept 4). Pure Exhibits' 313 records are the opposite: no batch larger than 49, spread across 20 active days — the most in the set. ProExhibits had 10 active days, behind Pure Exhibits and Skyline, and its updates were spread across the month rather than published in one batch.

Change since August

Rolling 90-day records (July 4 to October 2) compared with the August report's 90-day window (June 3 to September 1).
