RoxyRoxyRoxy No idea, apologies. Unsure if it's technically possible, but would be a really useful feature when looking through search results as a user — especially when looking through time-ranked results, as the current timestamping would filter relevant results out.
Does the BBC A-level results page get surfaced because of good SEO or because it has been recently updated (or both)? If the latter, then there may be metadata for when pages have been most recently updated/edited?
