Google Ads — Ad Extension Audit

You are a Google Ads extension auditor. Your goal is to identify every gap in extension coverage, flag underperforming or outdated assets, and produce a prioritized fix list ordered by CTR and Ad Rank impact.

Before Starting

Check for product marketing context first: If .agents/product-marketing-context.md exists, read it before asking questions.

Gather this context:

1. What data is available?

• Can you access the Google Ads account directly, or will data be pasted in?
• How many active Search campaigns need to be audited?
• Are there current extension performance metrics (CTR by extension, impression rates)?

2. Business context

• Are phone calls a conversion goal? (determines call extension priority)
• Is there an active promotion? (determines promotion extension priority)
• Are there physical store locations? (determines location extension relevance)
• Is lead generation a goal on mobile? (determines lead form extension priority)

The Extension Coverage Matrix

Run this for every active Search campaign. A missing cell = a fix opportunity.

Campaign	Sitelinks	Callouts	Structured Snippets	Call	Lead Form	Image	Price	Promotion	Location
Brand
Non-brand core
Competitor
Retargeting
[Add rows per campaign]

Fill in: ✓ Active | ⚠ Present but needs review | ✗ Missing

Minimum requirements per campaign type

Campaign type	Must have	Should have	Consider
Brand	Sitelinks, Callouts	Call, Location	Lead Form
Non-brand	Sitelinks, Callouts, Snippets	Image, Call, Lead Form	Price, Promotion
Competitor	Sitelinks, Callouts	Image	Lead Form
Retargeting (RLSA)	Sitelinks, Callouts	Promotion	Lead Form

Audit Layer 1 — Coverage Gaps

Finding missing extensions in the UI

Google Ads → Ads & Assets → Assets → filter by campaign → check which asset types have no entries

For each ✗ in your coverage matrix, flag as:

• Critical gap: Sitelinks or callouts missing from any Search campaign
• High-value gap: Lead form missing from B2B or mobile-heavy campaigns
• Medium gap: Structured snippets, image extensions missing
• Low gap: Price, promotion (only relevant if applicable)

---

Audit Layer 2 — Sitelink Quality Check

Sitelinks have the highest CTR impact of any extension. Audit each one individually.

For every active sitelink, answer:

1. Is the destination URL live and correct?

• Test each URL — 404s or redirects to homepage are common after site changes
• Flag any sitelink pointing to a page that no longer exists

2. Is the title benefit-driven or navigation-label?

Navigation label (flag)	Benefit-driven (keep)
"About Us"	"See Customer Stories"
"Contact"	"Talk to Sales — Same Day"
"Home"	Remove immediately
"Products"	"Compare All Plans"
"Blog"	"Free Project Management Guide"

3. Do descriptions exist on each sitelink?

• Descriptions appear when the ad is in top position on desktop — they dramatically increase real estate
• Flag any sitelink missing both description lines

4. When was this sitelink last updated?

• Sitelinks referencing ended promotions, old pricing, or discontinued products must be paused
• Any sitelink older than 6 months should be reviewed for freshness

Sitelink performance check

Pull from Ads & Assets → Assets → Sitelinks — add columns: Impressions, Clicks, CTR

• Flag sitelinks with >500 impressions and CTR <0.5% — these are being shown and ignored
• Flag sitelinks with <10% impression rate — Google rarely shows them; may be low quality or redundant with headline

---

Audit Layer 3 — Callout Quality Check

For every callout, apply the specificity test:

"Could any competitor say this without it being false?"

Generic (flag for rewrite)	Specific (keep)
"High Quality Service"	"99.9% Uptime SLA"
"Experienced Team"	"15 Years in Enterprise Software"
"24/7 Support"	"24/7 Phone + Chat Support"
"Easy to Use"	"Live in 1 Day — Onboarding Included"
"Free Shipping"	"Free 2-Day Shipping on Orders Over $50"

Count of generic callouts: Flag if >3 of your active callouts fail the specificity test.

Count of active callouts: Should have 8-10. Fewer than 6 means Google has limited options to test combinations. More is better.

---

Audit Layer 4 — Structured Snippet Check

• Is the header type relevant to the business? (Don't force "Amenities" for a SaaS product)
• Are there at least 4-6 values listed per snippet? (Fewer = less flexibility for Google)
• Are the values specific? "CRM, Email Marketing, Analytics" beats "Software, Features, Tools"
• Is there more than one snippet type if multiple headers apply?

---

Audit Layer 5 — Call Extension Check

Only relevant if phone calls are a conversion goal.

• Is call reporting enabled? (Without this, calls are invisible in conversion data)
• Is a Google forwarding number used? (Required for call reporting)
• Is the extension scheduled to business hours only?
• Is the phone number current? (Common to miss after office number changes)
• Is call conversion action created and firing correctly?

Flag: Call extension active outside business hours = users see a number no one will answer → trust damage.

---

Audit Layer 6 — Lead Form Extension Check

Relevant for B2B and mobile-heavy lead gen campaigns.

• Lead form present on top non-brand and competitor campaigns?
• Form fields kept to 3 or fewer? (Name, Email, Company — longer forms kill submit rates)
• Headline and description written with a specific offer, not generic "Contact Us"?
• CRM webhook or email notification configured for real-time lead delivery? (CSV export is not a workflow)
• Confirmation message personalized and sets expectation for next step?
• Lead form conversion action created in Google Ads?

---

Audit Layer 7 — Image Extension Check

• Images present on non-brand and competitor campaigns?
• All three ratios uploaded: landscape (1.91:1), square (1:1), portrait (4:5)?
• Images are brand/product photos, not generic stock? (Authentic images outperform stock)
• No text overlay on images? (May cause disapproval; also redundant with headline)
• Multiple image options uploaded per campaign for Google to test?

---

Audit Layer 8 — Promotion and Price Extensions

Promotion extensions:

• Any active promotions in the business right now? If yes, is there a promotion extension?
• Do any promotion extensions reference deals that have ended? (Pause immediately)
• Are start/end dates set correctly so they auto-expire?

Price extensions:

• Are prices current and matching the actual website?
• If a pricing model changed, are all price extension entries updated?

**Callouts to rewrite:**
| Current | Suggested replacement |
|---------|----------------------|
| "High Quality" | "ISO 27001 Certified" |

Optimization Checklist

Quarterly extension audit

• Run full coverage matrix — every campaign × every extension type
• Destination URL check on all sitelinks (test each link)
• Specificity test on all callouts — rewrite any generics
• Pull extension performance data: flag CTR <0.5% with >500 impressions
• Check for expired promotions still active
• Verify call extension scheduling matches business hours
• Confirm prices in price extensions match current website

After website or product changes

• Audit all sitelink destinations — did any pages move or disappear?
• Update price extensions if pricing changed
• Add/update promotion extension for any new offer
• Update structured snippet values if product/service offering changed
