How to Construct Backlink Network by Linking Notes in Obsidian

Obsidian is a powerful note-taking app that allows you to create a network of interconnected notes using backlinks. Backlinks allow you to link your notes together, creating a web of associated ideas and allowing you to visualize connections. Constructing a robust backlink network is one of the best ways to leverage Obsidian for notetaking, research, and knowledge management.

What are Backlinks in Obsidian?

Backlinks in Obsidian refer to the bidirectional links created when you link one note to another using the double bracket [[]] Wikilink format.

For example:

In my note on [[Atomic Habits]], I discuss how small habits compound over time.

This creates a link to a note titled “Atomic Habits”. If that note doesn’t already exist, Obsidian will create it when you click the link.

Additionally, Obsidian tracks backlinks automatically. So if Note A links to Note B, then Note B will now show Note A as an incoming backlink.

Benefits of Backlinks

Backlinks provide the following key benefits:

  • Interconnectivity – Backlinks allow you to link disparate ideas together into a web of associated notes.
  • Discoverability – Backlinks make it easy to discover related content through bidirectional links.
  • Context – Backlinks show you the context in which a note is referenced in other notes.
  • Visualization – Obsidian provides graphical visualizations of backlink networks.

How to Create Backlinks in Obsidian

There are two ways to create backlinks in Obsidian:

1. Wikilinks

Wikilinks use the [[double bracket]] format:

Here is my note on [[Atomic Habits]].

To create a wikilink:

  • Type [[
  • Type the name of the note you want to link to
  • Type ]]

If the note doesn’t exist, Obsidian will create it when you click the link.

2. Markdown Links

You can also use Markdown format links:

Here is my note on [Atomic Habits](atomic-habits).

The text in the first bracket is the linked text, while the text in parentheses is the note name.

Constructing a Backlink Network

Here are some tips for systematically building a network of backlink connections:

  • Link liberally – Get in the habit of linking between notes frequently using the [[]] wikilink format.
  • Use aliases – Create [[alias|aliases]] to refer to the same note in different contexts.
  • Review backlinks – Periodically review backlinks to find opportunities to improve connections.
  • Prune judiciously – Prune extraneous backlinks, but don’t go overboard. Some redundancy is good.
  • Add context – When adding links, provide context on the relationship, don’t just link for linking’s sake.
  • Use tags – Use tags to connect notes that don’t warrant a direct link.
  • Leverage unlinked mentions – Convert unlinked mentions to backlinks to strengthen the network.
  • Visualize the network – Use graph view and backlink maps to visualize the shape of your network.

By following these tips, you can organically create a rich network of interconnected notes that forms the backbone of your Obsidian knowledge base.

Advanced Backlink Techniques

Here are some more advanced techniques for backlink networks:

Embed Notes

Use ![[]] embed links to display a live preview of the linked note:

![[Atomic Habits]]

This is great for providing context without leaving the current note.

Link to Headings

Link to specific headings within notes using #:

[[Atomic Habits#The 2-Minute Rule]]

This heading link will scroll the linked note to the heading.

Link to Paragraphs

Install the Copy Block Link plugin to copy links to specific paragraphs, then link to them:

[[Atomic Habits#^4f9b3a]]

The paragraph links won’t display nicely, but will scroll to the intended paragraph.

Transclude Notes

Use the Transclusion plugin to embed sections of other notes using <<>>:

<<[[Atomic Habits]]>>

This will embed the entire linked note. You can also target specific headings or blocks.

Link Folders

You can link to folders using [[Folder Name]]. This is helpful for navigation and attaching folders to index notes.

Conclusion

By mastering backlinks in Obsidian, you can construct an interconnected personal knowledge base that enhances discoverability, context, and visualization of your notes. Consistently linking related notes creates a network effect that increases the value of your notes exponentially. Start linking early and often to see the benefits.
