Google’s John Mueller mentioned in a webmaster hangout video that Google can present both the unique revealed date or the final modified date of URL of their search outcomes snippets. He mentioned they’re versatile about these dates and if the content material considerably modified, they might use the final modified date versus the primary revealed date.
He mentioned this on the dates wrong usually in search and it’s one thing they continue to work on – in reality, as you may see above, Google has a “dates team” merely dedicated to determining dates of content material on the net.
