To group different posts on different pages in Tumblr, you first need to tag your posts with categories -- you can do this when you create a post or retrospectively from the Mass Post Editor (click "Posts" from the dashboard to find it). Once your posts are correctly tagged, you can then set up a series of links through the customization screen that display posts matching a certain tag.

Step 1

Log in to Tumblr and click the cog icon at the top of the screen to enter the Settings page. Select the name of the blog you want to work with and choose "Customize" by the Theme heading.

Step 2

Click "Add a Page." On the resulting dialog choose "Redirect" from the drop-down list of options on the left, which shows "Standard Layout" by default.

Step 3

Toggle the "Show a Link to this Page" option to on and give the link a label. This should reflect the type of content that it leads to (e.g. news or photos).

Step 4

Enter any Web address into the URL box. This is merely a placeholder for the redirect link and won't actually be used, though you may want to keep it relevant to the content of the posts.

Step 5

Enter the URL "/tagged/" in the "Redirect to" box, where is the address of your Tumblr and is the tag you want to link to. Clicking the link will display all the posts tagged with .

Step 6

Click "Save" and then the back arrow (top left) to return to the customization screen. Choose "Exit" to go back to the Tumblr dashboard.
