We all are aware of the cache date in Google Searches. However, the belief that it is an indicator of crawl rate of various bots has been shattered by Google’s John Mueller.
A certain Mats Tolander asked on Twitter, “Has the rate at which the index refreshes slowed down over the past 5-6 weeks? A lot of Google cache dates older than i’d expected.”
To this query, John replied in negative, saying, “Not that I’m aware of — but I’d be cautious using the cache dates for anything like that, they’re not indicative of that.”
So, all who think that if the cache date is outdated, don’t need to worry about it as it is not an indication of the bots crawling less. Google doesn’t always update the cache date in every crawl.
