One for the record. I find it rather annoying that Tumblr haven’t bothered to make Tumblr as a platform more optimized for Search. Wordpress is better optimized, every single post will get a unique friendly URL, page title and H1 - not so with Tumblr!
But Wordpress? Oh my, export Tumblr into Wordpress it’ll take an age to customise each post to get all the imagery and video displaying right - oh and then there’s the missing titles. So in the end you spend more time formatting - where as in Tumblr you’d spend less time formatting and more time discovering and interacting - much more productive.
It would still be better if Tumblr was better optimised. EVERY post should have a title - regardless.
