Course → Module 3: Entity Linking: Connecting Your Digital Presence
Session 6 of 6

Entity linking is not a one-time project. Profiles get deleted. Platforms change their URL structures. Businesses move, rebrand, or add new social accounts. A link that worked in January can be broken by March. A bidirectional connection can become unidirectional without you noticing.

This session establishes a quarterly audit process that catches these problems before they erode your entity authority.

Why Links Break

Understanding the common causes of broken links helps you anticipate problems before they happen:

Cause Example Effect on Entity Graph
Platform URL change Twitter becomes X; old URLs may redirect sameAs points to redirect, not canonical
Profile deletion Old Google+ links, abandoned Facebook pages sameAs points to 404; broken edge
Username change Rebranding from @oldname to @newname All references to old URL break
Domain migration Moving from example.com to newexample.com All profile backlinks point to old domain
Platform interface change YouTube moves link fields in settings Previously set links may be cleared
Team member departure Admin leaves, profile access lost Cannot update backlinks on the profile
SSL certificate change Moving from http to https All sameAs URLs with http:// are now outdated
Profile merger Facebook merges duplicate pages URL changes to the surviving page

Audit Checklist

For each profile in your entity graph, verify the following:

1. URL Resolution

Visit each URL in your sameAs array and each visible link on your website. Does it load? Does it redirect to a different URL? A 301 redirect is not necessarily broken, but your sameAs should point to the final destination URL, not the redirect source.

2. Backlink Presence

On each profile, verify that the website URL field still contains your correct, canonical website URL. Platform updates can sometimes clear fields or change formatting.

3. NAP Consistency

Check that the name, address, phone number, and description on each profile match your canonical entity data from Module 1. Pay attention to:

4. Profile Activity

An inactive profile is worse than no profile. If a social account has not been updated in over a year, it signals abandonment. Either reactivate it with fresh content or consider removing it from your sameAs and visible links.

5. New Profiles

Have you created any new profiles since the last audit? A new Threads account, a new industry directory listing? Add them to your sameAs array and visible links.

The Audit Spreadsheet

Maintain a persistent spreadsheet with the following columns:

Column Description
Platform LinkedIn, Facebook, YouTube, etc.
Profile URL The canonical URL of the profile
In sameAs? Y/N
In visible links? Y/N, and where (footer, about, contact)
URL resolves? Y/N/Redirect
Backlink present? Y/N
NAP match? Y/N (note discrepancies)
Last active Date of last post or update
Status Healthy / Needs fix / Deactivate
Audit date When this row was last checked

Fixing Common Issues

Broken URL (404)

Remove the URL from sameAs and visible links. If the profile was deleted intentionally, no further action. If accidentally, recover it or create a new one and update all references.

Redirect

Update your sameAs and visible links to point to the final destination URL. A redirect is not an error, but your links should always point to the canonical endpoint.

Missing backlink

Log into the profile and add your website URL. This is the most common issue and the easiest to fix.

NAP inconsistency

Update the profile to match your canonical data. If the profile does not allow edits (e.g., a third-party directory), contact the directory to request a correction.

Inactive profile

Either publish fresh content or, if the platform is no longer relevant to your entity, remove it from sameAs and visible links. Do not keep dead profiles in your entity graph.

Key concept: A link audit is entity hygiene. Like checking smoke detectors or changing oil, it is unglamorous work that prevents catastrophic failure. A quarterly cadence catches problems before they compound. An annual cadence lets rot set in.

Automating Parts of the Audit

Some parts of the audit can be partially automated:

The parts that cannot be automated are backlink verification (you need to log in and check each profile) and activity assessment (requires judgment about whether a profile is sufficiently active).

Audit Schedule

Set a recurring calendar event for the first week of every quarter. The full audit takes 30 to 60 minutes for a small business with 5-10 profiles. For larger entities with 20+ profiles, budget 2 to 3 hours. The time investment is small compared to the cost of letting your entity graph decay.

Assignment

Perform your first complete link audit.

  1. Create the audit spreadsheet with all columns described above.
  2. Populate it with every profile from your entity graph map.
  3. Check each row: URL resolution, backlink presence, NAP consistency, activity status.
  4. Fix every issue you find. For each fix, record what was wrong and what you changed.
  5. Set a recurring calendar event for the next quarterly audit (3 months from today).
  6. Write a one-paragraph summary of the audit findings: how many profiles checked, how many issues found, how many fixed.
