Shannon Liao for The Verge:

Tumblr’s traffic has dropped nearly 30 percent since December.

Tumblr’s global traffic in December clocked in at 521 million, but it had dropped to 370 million by February, web analytics firm SimilarWeb tells The Verge. Statista reports a similar trend in the number of unique visitors. By January 2019, only over 437 million visited Tumblr, compared to a high of 642 million visitors in July 2018.

I think everyone assumed Tumblr’s traffic would drop somewhat but this is nuts. The company’s updated policy on content has obviously had an effect on users of all kind.

My usage of the site has become basically non-existent and I’ve noticed many of the people I follow doing the same, even though none of us were posting content that would now be deemed inappropriate. Between the sudden need to cast aside a large part of the community, coupled with the inaction against pages made by hate groups, I won’t be shocked if traffic continues to decline.
