Frame with no title
What it means
An <iframe> with no title is announced as just "frame". Someone navigating by frame has no way to tell the video from the map from the advert.
How to fix it
Add title describing what the frame contains: "Office location map", not "iframe". A frame that is purely decorative or offscreen should carry aria-hidden="true" instead. WCAG 4.1.2.
Finding it in CrawlStat
After a crawl, open Issues and pick Frame with no title. Click Show all in Pages to filter the Pages table to the affected pages, or Export affected to hand the list to whoever owns the fix. Audit ID: a11y_iframe_without_title.
