Retain session replay recordings for at least 90 days to cover standard ad platform chargeback windows. For high-risk verticals or complex fraud investigations, extend this to 2–3 years to align with legal and audit requirements. This recommendation balances the practical need to dispute invalid clicks with the cost and compliance burden of storing sensitive user data.
Why Retention Windows Matter for Fraud
Session replays serve as the "evidence dossier" in your fight against invalid traffic. When you identify bot activity, click fraud, or pixel poisoning, you need more than just a log entry; you need the visual proof of the session to win disputes with ad platforms like Google or Meta. If your retention window is too short, you lose the ability to build a case once the fraud is discovered in your CRM or billing reports.
Fraud is often not detected immediately. A bot network may operate for weeks before you notice a spike in bounce rate or a drop in conversion quality. By the time you run a deep analysis, the session data may already be gone. That is why a 90-day baseline is not just a convenience—it is a minimum safety net.
The 90-Day Baseline
For most digital advertisers, 90 days is the functional minimum. This window aligns with the typical timeframe for identifying discrepancies in ad spend and filing manual refund requests. If you wait longer than three months to audit your traffic, the likelihood of successfully reclaiming budget from major ad platforms decreases significantly.
Industry standards for chargeback windows—such as those used by credit card processors and ad platforms—often fall between 60 and 120 days. A 90-day retention period covers most of these windows. It also gives you enough time to run monthly or quarterly audits without overburdening your storage systems.
However, 90 days is not a universal rule. Some platforms allow refund claims for up to 180 days, and certain legal proceedings may require data from earlier periods. Always check the specific terms of your ad platform and consult with legal counsel to confirm the minimum for your jurisdiction.
High-Risk and Legal Considerations
If your business operates in a high-risk vertical—such as finance, insurance, or healthcare—or if you are managing large-scale enterprise ad budgets, you should consider a 2-to-3-year retention policy. This ensures that if a fraud investigation escalates to a legal or regulatory audit, you have the historical data required to prove the nature of the traffic that hit your conversion pixels.
Regulated industries often face record-keeping mandates that extend beyond typical business needs. For example, financial institutions may need to retain evidence of transaction integrity for several years. Session replays can serve as supporting documentation in such cases.
"Session replays are your strongest evidence in a refund dispute," says a fraud analyst at BotRefund. "If you delete them too early, you lose the ability to prove invalid traffic. For high-risk accounts, we recommend keeping them for at least two years—you never know when a legal question will surface."
Legal counsel can help you determine the exact retention period based on applicable laws, industry regulations, and the statute of limitations for fraud claims. In some cases, you may need to preserve data longer if a dispute is already in progress or if you anticipate litigation.
How to Structure Your Retention Strategy
Effective data management requires balancing storage costs with the need for actionable evidence. Use this framework to decide your policy:
- Standard PPC Campaigns: 90 days. This covers the typical window for identifying and disputing invalid clicks.
- High-Volume/Enterprise: 1 year. Allows for quarterly audits and long-term trend analysis of bot behavior.
- Regulated Industries: 2–3 years. Consult with legal counsel to ensure your digital evidence aligns with industry-specific record-keeping mandates.
When setting your policy, consider the cost of storage versus the potential loss from an unresolved fraud claim. A single successful refund can cover years of storage fees. Also, think about the format: compressed video files and metadata logs are cheaper to store than raw, high-resolution recordings.
Automate the process. Use tags to flag suspicious sessions and move them to a separate, longer-term archive. This way, you do not have to keep everything for years—only the sessions that matter.
Trade-offs and Limitations
Longer retention is not always better. Storing session replays for years increases your data footprint, which raises costs and expands your compliance obligations under privacy laws like GDPR and CCPA. You must ensure that your storage is encrypted and that you have a clear policy for purging data once the retention period expires.
Another limitation is data accuracy. Session replays are only useful if they are complete and correctly attributed. If you fail to log the GCLID or FBCLID alongside the video, the replay loses its evidentiary value. Similarly, if your recording tool misses certain interactions, you may have gaps that weaken your case.
Finally, consider the risk of data breaches. The longer you hold sensitive user data, the longer it is exposed to potential theft. Implement strict access controls and regular security audits to mitigate this risk.
Common Mistakes in Data Retention
Many advertisers make the mistake of treating all session data equally. Avoid these pitfalls:
- Deleting Flagged Sessions Too Early: If a session is flagged as suspicious by your bot detection tools, move it to a "long-term evidence" folder rather than letting it expire with standard traffic.
- Ignoring Data Residency: Ensure your storage provider complies with local data privacy laws, especially if you are collecting data from users in the EU or specific US states.
- Lack of Metadata: Storing the video is not enough. Ensure you are also logging the GCLID or FBCLID alongside the replay so you can link the video directly to the specific ad spend.
- Not Automating Retention: Manual deletion is error-prone. Use automated policies that apply different retention periods based on session flags and risk levels.
Key Facts for Fraud Evidence
| Feature | Benefit for Fraud Investigation |
|---|---|
| Behavioral Logs | Provides proof of non-human patterns like robotic mouse movements or superhuman input speeds. |
| GCLID/FBCLID Tracking | Links specific session replays to the exact ad click for easier refund disputes. |
| Automated Flagging | Reduces manual review time by highlighting sessions that lack human tremor or natural scroll patterns. |
Follow-up Questions to Ask Your Team
Before finalizing your retention policy, ask these questions:
- What is the maximum refund claim window for each ad platform we use?
- Are there any pending or anticipated legal disputes that require longer preservation?
- How quickly can we detect fraud in our current workflow? If detection takes longer than 90 days, we need a longer baseline.
- Do we have the storage infrastructure to support a 2–3 year policy without breaking the budget?
- Have we documented our retention policy and communicated it to all relevant stakeholders?
Frequently Asked Questions
Does storing more data increase my risk?
Yes. Retaining data longer increases your compliance burden. Always ensure your storage is encrypted and that you have a clear policy for purging data once the retention period expires.
Can I use session replays for legal disputes?
Yes, provided the data is collected in compliance with privacy regulations. They act as powerful visual evidence in billing disputes with ad platforms.
What happens if I don't have proof?
Without client-side behavioral proof, you are reliant on the ad platform's internal filters, which often fail to catch sophisticated residential proxy bots.
How do I know if my retention is sufficient?
If you are consistently losing refund disputes because you lack "evidence dossiers," your retention window or your data collection process needs to be extended.
Can I extend retention for specific sessions?
Yes. Use automated rules to flag suspicious sessions and move them to a longer-term archive. This is a cost-effective way to keep evidence without storing everything for years.
What about privacy regulations like GDPR?
You must have a lawful basis for storing session replays. Typically, this is legitimate interest in fraud prevention. Ensure you disclose the retention period in your privacy policy and offer a way for users to request deletion where required.
