How to Set Expiring Document Links: A Best Practice Guide

An expiring document link is exactly what it sounds like: a shared URL that stops working after a predefined date or period. The client (or recipient) can access the document during the active window; after the expiry, the link returns an error or access denied.

For marketing agencies and fractional CMOs, expiring links are the simplest possible defence against zombie links — they make the default state "access ends" rather than "access continues indefinitely."

When to Use Expiring Links

Document type	Recommended expiry
Ongoing engagement deliverables	Engagement end date + 30 days
Time-sensitive proposals	14 days
Confidential competitive analysis	Meeting date + 7 days
Proprietary frameworks (if shared at all)	Single use / immediate expiry
Monthly reports	90 days (replaced by next month's report)
Final engagement archive	12 months (for client reference)

The key principle: expiry should be set at the point of sharing, based on how long the document needs to be accessible, not as a remediation step after problems arise.

How to Set Expiry Dates in Google Drive

In Google Workspace Business Standard and above:

1. Open the file's sharing settings
2. Click the pencil icon next to the person or group with access
3. Select "Add expiration date"
4. Set the date

This works for named-individual access. It doesn't work for "anyone with the link" sharing (another reason to use named access rather than link access).

Limitation: This requires setting expiry per person per file. For an engagement with 15 shared files and 3 client contacts, that's 45 individual expiry settings — significant overhead if done manually.

How Firma Handles Expiry at Scale

Firma's time-bomb sharing feature sets expiry at the engagement level, not the file level. When you configure an engagement's access window, all documents in that engagement's portal expire together when the engagement wraps. One decision, applied automatically to everything.

For sensitive documents that need earlier expiry than the engagement as a whole, individual document time-bombs can be set within the portal — without affecting the rest of the engagement's access window.

Building Expiry Into Your Delivery Workflow

The point of failure for most agencies is that expiry is not part of the delivery workflow — it's an afterthought (if it happens at all). The fix is simple: make "when should this expire?" a required field when setting up any document share.

If you can't answer the question when you're sharing the document, that's a signal that you haven't thought through the access lifecycle — and it's the right moment to do so, not six months later when the engagement is a distant memory.

Frequently Asked Questions

What is an expiring document link?

An expiring document link is a shared URL that becomes inaccessible after a predefined date or event. After expiry, attempting to open the link returns an access-denied response. This eliminates the need for manual revocation and prevents zombie link accumulation.

Does Google Drive support expiring share links?

Google Drive supports access expiry for named-individual sharing in Business Standard and above plans — you can set an expiration date per person per file. It does not support expiry for "anyone with the link" sharing. For link-based expiry, use a client portal that supports time-bound sharing at the URL level.

How long should a marketing agency keep a shared document accessible after delivering it to a client?

For routine deliverables: the duration of the engagement plus 30–90 days for reference. For sensitive or IP-containing documents: consider time-bombing them to expire within days of the specific purpose they served. For final engagement archives: 12 months is a reasonable default, giving the client time to reference work from the completed engagement.
