Is an electronic signature legally binding?

Yes. Electronic signatures are legally enforceable under the federal ESIGN Act (15 U.S.C. §7001) and UETA in most states when intent, consent, attribution, and record retention are satisfied.

Do I need a notary or witnesses for this addendum?

Generally no for commercial marketing addenda; notarization or witnesses are only required when state law or a specific transaction (e.g., deed) mandates them. Check state notary rules for exceptions.

What happens if the signer's name doesn't match records?

A name mismatch can complicate attribution and payment authorization. Use full legal names and include title and contact info to reduce identity disputes during reconciliation.

Can a consumer withdraw electronic consent?

Yes—consumer‑facing electronic records must include an ESIGN consumer disclosure and a method to withdraw consent in accordance with 15 U.S.C. §7001(c).

How should signed addenda be stored?

Store tamper‑evident signed PDFs with the audit trail in a secure repository that supports retention policies and access controls for legal and accounting purposes.

What if a platform suspends the ad account?

Document contingency plans in the addendum for account suspensions, including notification procedures, pausing spend, and responsibilities for reinstatement or refunds.

What the Marketing PPC Addendum Is and When It Applies

A Marketing PPC Addendum is a contract amendment that defines pay‑per‑click campaign specifics appended to a master services agreement or marketing contract. It documents campaign scope, budget, billing terms, tracking and reporting requirements, platform permissions, KPI targets, creative ownership, and change controls so both agency and advertiser share clear operational and financial expectations.

Why add a PPC Addendum to your marketing agreement

A focused addendum reduces dispute risk by translating campaign goals into measurable obligations, clarifies billing for ad spend and management fees, and preserves auditability for reporting and compliance.

Who typically completes a Marketing PPC Addendum

Agencies, in‑house marketing teams, and client procurement or legal teams commonly prepare and sign a PPC Addendum before campaign launch.

Digital marketing agencies that manage paid search and need documented budgets, access and KPIs.
Advertisers or brand marketing teams that require performance benchmarks and billing transparency.
Legal, procurement, or finance teams that validate indemnities, ownership, and payment terms.

Ensure the signatory has budget authority and the operational contacts listed can grant platform access and make campaign decisions.

Stepwise process to complete and execute the addendum

Follow these sequential steps to ensure the PPC Addendum is complete, authorized, and retained.

01

Draft: Populate fields with campaign scope and budget.
02

Review: Legal and finance confirm terms and billing allocation.
03

Sign: Authorized parties execute electronically or in writing.
04

Distribute: Share fully executed copy with operations and accounting.

Essential clauses to include in a professional PPC Addendum

A concise addendum focuses on measurable obligations and operational permissions. Include clauses that control spend, access, reporting, and ownership to reduce future disputes.

Budget and Spend

Specify total ad budget, allowed overspend tolerance, who pays platform invoices, and whether agency or client manages the payment method.

Scope of Services

Define campaign platforms, targeting parameters, geographic limits, ad formats, and services included such as keyword research, creative, or bid management.

KPIs and Reporting

List primary metrics, reporting cadence, acceptable measurement windows, and the format of reports provided for billing reconciliation.

Access and Credentials

State required account access levels, whether accounts are client‑owned or agency‑managed, and rules for credential transfer at termination.

Creative Ownership

Clarify ownership of ad creatives, rights to reuse assets, and any license terms for third‑party assets used in campaigns.

Termination and Amendments

Include notice periods, final accounting of spent media, and the process for amending budgets or scope mid‑campaign.

Security and compliance reminders for the addendum

Encryption: TLS 1.2/1.3 in transit; AES‑256 at rest

Authentication: Use MFA or strong signer verification

Audit Trail: Capture timestamps, IP, and action history

HIPAA Requirements: Execute BAA if PHI is processed

Legal Frameworks: ESIGN and UETA govern e‑signature validity

Certifications: SOC 2 Type II and ISO 27001 where applicable

Common preparation errors to avoid

Leaving budget and invoicing responsibilities ambiguous, which often causes double billing or unpaid platform charges and operational delays.
Failing to list required account access and permissions, delaying campaign activation while credentials are exchanged or verified.
Vague KPI definitions that omit measurement windows or attribution models, producing disagreements at reporting time.
Not specifying amendment procedures for mid‑campaign budget or scope changes, leading to informal approvals and billing disputes.

Consequences of an incorrect or incomplete PPC Addendum

Billing Disputes: Unclear fees can lead to delayed payments and contract disputes

Platform Suspension: Policy violations risk ad account suspension or penalties

Data Access Loss: Missing transfer terms can impede analytics and reporting

Regulatory Exposure: HIPAA or consumer privacy gaps can create compliance risk

Operational Delays: Credential issues delay campaign start or optimization

Contract Breach: Poorly defined deliverables increase litigation risk

A straightforward routing and signing workflow reduces friction and preserves a complete record of approvals.

Prepare Document: Author and attach scope and budget schedules
Assign Signers: Designate authorized signatories with titles
Request Signatures: Send signing links or initiate eSignature workflow
Archive: Store executed copy with audit trail
