Update your Tumblr profile.
You can customize your Tumblr profile at https://www.tumblr.com/customize/. Here you can update your blog name and description, which is a simple first step towards building your profile.
Creating your Tumblr profile.
Set your Tumblr Title on the right-hand side of the customizer. Be sure it reflects your business and ideally matches the business name you established while planning your Social Media Strategy.
Your Tumblr Description (also on the right-hand side) can be updated to include the long social media profile description you created as part of your Social Media Strategy process.
Both your title and description will be pretty common across most social media profiles you create, but you may decide to customize it for one profile or another to appeal to that particular platform.
Updating your Tumblr profile.
Once set, your Tumblr profile details should be fairly static and not need updating, but it’s worth checking on once every few months to make sure it’s still consistent with the brand image you’re presenting across the rest of your social media profiles.
