TL;DR
Google’s support for the unavailable_after meta attribute allows pages to be removed from search results after a specified date. However, if the date is updated, Google may not detect the change if it doesn’t crawl the page again before the original date. Google’s Gary Illyes suggests that dynamically extending the date is fine, but it requires Google to recrawl the page to recognize the new date.
Key Developments
- Google’s unavailable_after meta attribute can remove pages from search results after a set date.
- If the date is updated, Google might not notice unless it recrawls the page before the original date.
- Gary Illyes from Google indicates it’s acceptable to extend the date, but it depends on Google recrawling the page.
- Using unavailable_after dynamically in high-turnover environments may not have negative SEO implications.
Optimixed Analysis
The use of the unavailable_after attribute presents a potential issue for dynamic content management. While it can effectively manage content lifecycle, the reliance on Google’s recrawl schedule introduces uncertainty. This suggests a risk for content that needs to be removed or extended promptly. Professionals should consider the timing of Google’s crawls and the potential for pages to remain indexed longer than desired if dates are not updated in time.
