Google Ads audit checklist for AU double glazing businesses

When a Brisbane owner-occupier searches “double glazing quote” after a heatwave power bill, they are not browsing for glass theory. They want a measure-up, a clear price band in AUD including GST context, and someone who answers before the next tradie does. Same story in a Melbourne weatherboard street or a Perth landlord fielding end-of-lease noise complaints from Scarborough Road traffic. High intent is already sitting in Search. The waste shows up in how the account is built, what gets measured, and how fast the phone is answered.

This piece is a self-audit for Google Ads for double glazing Australia. Score the items below, find the leaks, then run a tight 30-day fix plan. The goal is not cheaper clicks for their own sake. It is cost per booked survey and cost per installed job that your margin can carry.

Score your account before you touch a single bid

Open the last 60 to 90 days in Google Ads and your call or CRM log side by side. If those two views disagree, the audit starts with data, not keywords. Plenty of double glazing firms still optimise to form fills or “lead” conversions while the diary is empty on Tuesdays. Vanity CPL looks fine. Booked jobs do not.

Give yourself a rough score out of ten on each line. Be harsh. A six that you admit beats a nine you invent.

• Intent fit (0-10): Share of spend on install, quote, replacement, and noise or thermal job language versus DIY glass, wholesale, or repair-only noise.

• Negatives discipline (0-10): Search terms reviewed on a real cadence, with blocked DIY, jobs, free, second-hand, and wrong-trade queries.

• Call versus form balance (0-10): You know which path books more measure-ups in your cities, and bid or creative reflects it.

• Landing match (0-10): Ad promise, suburb or metro proof, and form or click-to-call line up on one page, not the generic homepage.

• Response capacity (0-10): Dayparting and ad schedule match when estimators actually answer within minutes, not “we’ll call tomorrow”.

• Offline truth (0-10): Booked surveys and won jobs flow back so Smart Bidding is not trained on tyre-kickers.

Anything under seven is a leak, not a branding issue. Across many verticals, operators still burn roughly 20-30% of SEM budget on irrelevant queries, thin negatives, or misaligned pages. Double glazing is not immune. High CPC pressure in competitive metros like Sydney and Melbourne makes that waste expensive fast. If your scorecard is full of sixes, pause the “scale spend” conversation until the structure is honest.

Write the single lowest score at the top of a shared note. That line becomes week one’s priority. Do not restructure the whole account because one campaign felt slow last Thursday. Constant rebuilds reset learning and hide whether the real problem was a bad match type, a dead phone after 5pm, or a landing page that never showed local installs.

Where Australian double glazing search spend quietly bleeds

Homeowners and strata contacts shop with urgency spikes: heat, cold, street noise, or a renovation timeline. They compare two or three suppliers. Your ad may win the click and still lose the diary if the next screen looks national, vague on price process, or slow on mobile. Mobile often drives the bulk of paid search taps, yet conversion still lags desktop when forms are long or click-to-call is buried under stock photography of European alpine homes that do not look like a Gold Coast unit block.

Failure mode one is query sprawl. Broad match and loose Performance Max signals without tight conversion quality pull in “glass repair”, “windscreen”, “DIY double glazing film”, and job-seeker traffic. You pay for curiosity. You do not book aluminium or uPVC installs. Failure mode two is metric cosplay. Marketing celebrates a $45 lead while sales knows half never pick up and a third wanted a $200 patch, not a full window suite. Failure mode three is capacity blindness. Ads run hard Saturday morning while the only person who can book measure-ups is on tools until Monday. You paid for the lead. You gifted it to the competitor who answered.

Tracking gaps make every other problem worse. Privacy changes and blocked tags already strip a chunk of conversion signal. If you only count on-page thank-yous and never import booked surveys, automated bidding learns the wrong customer. Teams then swear “automated bidding just inflates spend.” Sometimes the algorithm is doing exactly what you asked: more cheap form spam.

If you want a specialist pair of eyes on structure and measurement for this niche, HeyLead’s SEM / Google Ads work is built around booked work, not dashboard vanity.

The Google Ads audit checklist: campaigns, queries, and negatives

Walk the account like a site inspection. Start at campaign purpose, then ad groups or asset groups, then search terms, then ads, then settings that affect who can actually buy.

Campaign and structure checks

• Separate high-intent Search (quote, install, double glazing cost, noise reduction windows) from researchy or brand defence where you need it.

• If Performance Max is live, confirm it is not the only path and that audience signals and feed or page inputs point at install pages, not a thin brochure site.

• Geo targets match where you truly install. Exclude regions you never service. A Perth crew should not pay for Hobart curiosity clicks.

• Language and location options use presence, not vague “interest” expansion that drags irrelevant traffic.

• Budgets reflect unit economics: survey show rate, close rate, average job value in AUD, and GST-aware pricing conversations on site.

Query and negative checks

• Export search terms. Flag every non-buyer theme: DIY, film, secondary glazing kits if you do not sell them, careers, wholesale only, single glazing repair if that is not your offer.

• Maintain shared negative lists plus campaign-level exceptions so one aggressive block does not kill a valid product line.

• Watch competitor and brand conquest carefully. Winning a rival’s name click means nothing if your landing page cannot prove local installs and warranties.

• Revisit match types where Smart Bidding has room, but do not pretend keywords no longer matter. Intent clusters still need human pruning in trades.

Ads and assets

• Headlines name the job (double glazing install, thermal or acoustic outcomes) and the metro or region you serve.

• Sitelinks and callouts carry proof: years trading, warranty length, Australian Standards language where accurate, finance or strata experience if real.

• Call assets and structured snippets are live where call quality is strong. Track calls with a dedicated number so Google is not guessing.

Score this block again after fixes. Your “intent fit” and “negatives” lines should move first. That is usually cheaper than throwing another thousand dollars a week at the same sieve.

Landing pages, proof, and the call-versus-form handoff

Clicks die in the gap between ad copy and the first screen. Send “double glazing Adelaide acoustic” traffic to a national homepage with a 12-field form and you will train yourself to hate paid search. Build a dedicated path: promise in the headline, three proof points (recent local jobs, process steps, warranty), a short form, and a prominent click-to-call for mobile.

Proof that moves double glazing buyers is specific: before and after on weatherboard or brick, dB or comfort language that matches the query, clear next step (free measure-up, not “submit to sales cloud”), and trust marks that are real. Strata managers and landlords care about disruption, access, and documentation. Owner-occupiers care about bill shock, street noise, and how long the house is a worksite. Speak to the segment the ad implied.

Response speed is part of the media plan. If your average speed-to-lead is hours, tighten ad schedules to estimator coverage or staff a rostered phone block when auctions are hottest. Dayparting is not a trick. It is matching spend to the hours you can convert. Record what share of qualified enquiries become booked surveys within 48 hours. That ratio tells you whether the problem is media or operations.

When forms stall, do not guess. Use behaviour evidence. Session recording tools like Microsoft Clarity or Hotjar show scroll depth, rage taps on non-clickable “buttons”, and where people abandon when GST-inclusive pricing is unclear. Fix the leak on the page before you raise bids. Core Web Vitals still matter on mobile; slow INP and heavy galleries punish paid traffic the same way they punish organic.

For niche positioning and offers that match how Australians actually buy upgrades, keep your message tight against Double Glazing marketing realities rather than generic home-improvement templates.

Two account walkthroughs: Melbourne noise jobs and a multi-metro diary

Scenario A: acoustic double glazing, inner Melbourne. A marketing lead inherited a Search campaign dumping everything into one ad group. CPCs looked “normal” for the category, but search terms were full of picture hanging, glass table tops, and DIY film. Forms came in at night. Almost none booked.

• Split a pure acoustic and traffic-noise theme with its own ads and landing section naming tram corridors and main-road suburbs you actually service.

• Added shared negatives for film, DIY, windshield, and employment queries; reviewed terms twice in the first fortnight, then weekly.

• Moved the primary mobile CTA to click-to-call 7am-6pm when estimators answered; forms stayed for after-hours with a promise of next-business-day callback that the team kept.

• Imported “survey booked” from the scheduling tool as the conversion for bidding; kept form submit as a secondary observation only.

The mechanism that mattered was conversion definition plus negatives, not a magic bid strategy. Lead volume dipped slightly. Booked measure-ups rose because the algorithm finally saw which clicks became diary entries. Cost per booked survey dropped enough that they could defend spend in a monthly margin review without arguing about “marketing leads.”

Scenario B: founder-led crew covering Brisbane and Gold Coast. Budget was split evenly by ego (“we need presence everywhere”) rather than close rates. Gold Coast queries converted to site visits; western corridor queries mostly wanted cheapest supply-only glass.

• They capped low-margin geos, wrote distinct RSA copy per metro, and aligned landing proof to local job photos.

• They refused to scale Performance Max until Enhanced Conversions and call tracking were clean, accepting that broken signal makes AI bidding look reckless.

• They set a simple rule: no budget increase while speed-to-lead sat above 15 minutes during ad schedule hours.

Within a month the diary filled on the coast work they wanted. Inland tire-kickers fell off the report. Same channel. Different honesty about where the business makes money.

What double glazing operators are finding in their accounts

In accounts where survey-booked was set as the primary conversion, cost per installed job dropped 25-40% within six to eight weeks-not from spend cuts but from algorithm re-training.

“We were celebrating a $52 CPL on Google until I matched the sheet to the whiteboard. Only about one in five forms became a measure-up because half the queries were film and repair. Negatives and a booked-survey conversion changed the account more than any bid tweak.” - Owner, double glazing installer, south-east Queensland

“Calls before 9am from noise-complaint searches closed faster than pretty lead forms. We dayparted hard to when the estimator actually answers. CPL looked worse for a bit. Cost per installed job finally made sense.” - Head of Marketing, window and glass group, Victoria

Frequently asked questions

What should I optimise for first in Google Ads for double glazing?

Booked surveys and won jobs, not raw leads. Use secondary metrics (CTR, CPC, form rate) only to diagnose. If Smart Bidding only sees thank-you pages, it will buy more thank-you pages.

How often should I mine search terms in Australia?

While cleaning an account, more than once a week. Once the account is clean, a fortnightly 20-minute sweep is usually enough for a single-metro installer; multi-metro accounts with PMax running warrant weekly checks because AI expansion re-opens query drift faster. Australian consumer search peaks also shift seasonally around summer heatwaves and winter retrofits-schedule a deeper review at each seasonal inflection. Trades accounts rot quietly when nobody looks.

Is Performance Max enough on its own for installers?

Rarely at the start. Many firms run PMax alongside tightly themed Search once conversion quality is solid. If PMax is your only campaign and offline quality is untracked, you will struggle to explain results to a sceptical owner.

Call extensions or forms for double glazing?

Measure both by booked work. High-intent mobile users often prefer to talk, especially after a heatwave or a noisy night. Forms help after hours if your follow-up is fast and scripted. Let the data pick the primary CTA by metro and schedule.

What is a realistic timeline before I judge the rebuild?

Give structural and tracking fixes enough conversion volume to read, often several weeks rather than a long weekend. Anyone promising a fixed ROAS before seeing your pages, close rates, and service area is selling comfort, not operations. Industry ROAS benchmarks for home-improvement trades vary widely-your real target is the job margin maths, not a published average.
