The Link post type makes it easy to share links on Tumblr, with many details automatically populating into the posting form; adding links within other post types is also possible -- with the exception of Chat posts -- as is adding links to your blog's main page.
Click Link. If you've scrolled down your dashboard so the post type icons are no longer visible or you're on a different page, such as activity or settings, click the pencil to display the post type icons.
Type or paste a Web address into the text field. Tumblr automatically populates the posting form with information about the link, including a link title and, if available, a thumbnail image and brief summary; the posting form also gains additional fields.
Fill in the rest of the posting form with any additional information you wish to add and click Post.
Select the text you want to turn into a link to bring up contextual buttons with common text formatting functions and then click the Link button. This button has a diagonal infinity symbol as its icon.
Type or paste a Web address into the text field.
Click Done or press Enter.
Click the person icon and select Edit Appearance.
To add a link to a secondary blog rather than your primary, hover over the blog's title in the menu until a person icon appears and then click it to display various options for that blog, including "Edit Appearance."
Click Edit Theme to open a page displaying a list of theme options on one side and a preview of your blog's main page on the other.
Type or paste the following code into the Description field, replacing the Web address and link text with those you want to use:
<a href="http://www.google.com/">Google is great!</a>
The blog preview automatically updates to show the effect of your changes as you edit the description.
To return to the dashboard, click Exit and then click the home icon.
Tips & Warnings
- You can also edit your theme's HTML code directly to add links to any area, not just that reserved for the description (see Resources). However, this is only recommended if you're familiar with HTML code -- otherwise, there's a risk you might accidentally cause your theme to stop working altogether.
