Is deleting old content good for organic search rankings? Google’s SearchLiason, Danny Sullivan, recently addressed that question on his Twitter account, stating old content is not harmful and possibly helpful:
Are you deleting content from your site because you somehow believe Google doesn’t like “old” content? That’s not a thing! Our guidance doesn’t encourage this. Older content can still be helpful, too.
He linked the tweet to a Google Search Central post, “Creating helpful, reliable, people-first content.”
