Which of the last twenty clicks on your Google Ads account came from a landlord whose panel just died, and which came from a student pricing up a GSM system for a houseshare? If you can’t answer that from the dashboard in front of you, you’re buying clicks, not buyers.
That gap costs more than it looks like on a spend report. Every pound chasing a browsing homeowner who wants a ballpark figure is a pound not spent putting an engineer in front of a managing agent with three blocks and a fire door interlock that needs sorting before the next inspection. Add a website that doesn’t say clearly whether a price includes VAT, and you’ve got callers who argue on the phone before they’ve even booked a survey. More spend doesn’t fix any of that. A faster quote form doesn’t either. The leak is almost always somewhere specific and almost always fixable in an afternoon, once you know where to look.
A tactics list won’t find it for you. What finds it is going through the account the way you’d check a faulty panel: point by point, pass or fail, no guessing and no “it’s probably fine.” Below is the audit we run for intercom companies before we touch a single bid or ad.
Audit scorecard
-
1Residential and commercial traffic sitting in one campaign
A homeowner replacing a video doorbell and a facilities manager tendering a maintenance contract across six blocks are not the same buyer, and they shouldn't be bidding against each other inside one campaign. When they're lumped together, your Smart Bidding averages out to something that serves neither well, and your ad copy ends up generic enough to miss both.
-
2VAT shown inconsistently between the ad and the page it lands on
If you're quoting a price to a consumer, it needs to include VAT. Quote a managing agent or a commercial client and the convention flips: prices are normally shown excluding VAT, with the rate added separately on the invoice. Check your sitelinks, your landing page copy, and your quote form all agree on which audience they're talking to. A caller who feels misled on price before they've even met your engineer rarely books.
-
3Install, repair, and maintenance contract keywords lumped into one ad group
Someone searching "intercom not working" wants an engineer today, not a brochure. Someone searching "video door entry system cost" wants a quote they can compare. A managing agent searching "intercom maintenance contract" wants a tender document. One ad group serving all three means two of those three people see the wrong message and bounce.
-
4No negative list catching DIY, careers, and model-number research
Searches like "how to wire an intercom myself," "intercom engineer jobs," or someone just comparing a Comelit panel against a Paxton reader without any "install" or "repair" attached are not jobs waiting to be won. If your negative keyword list hasn't been reviewed in a few months, you're almost certainly funding some of this.
-
5One landing page carrying five different jobs
Video door entry, audio-only systems, GSM/wireless units, access control integration, and fire door interlocks are different sales with different proof points. A single "intercom services" page forces every visitor to self-qualify, scroll past content meant for someone else, and most won't bother. Each system type deserves its own page, even if it's short.
-
6The survey booking form lags on mobile
Only 55.9% of web origins pass all three Core Web Vitals checks, according to Google's own Chrome UX Report data from May 2026, and a caretaker standing outside a block with a dead panel on his phone isn't going to wait for your form to load. If your page fails this on mobile, every click you've paid for is already fighting your own site.
-
7Calls and WhatsApp enquiries not tied back to the keyword that won them
A growing share of first contact now arrives as a WhatsApp photo of a broken panel rather than a form submission, especially from managing agents forwarding on a resident's complaint. If that enquiry isn't logged against the campaign and search term that produced it, you've no idea which keywords actually turn into booked jobs versus which ones just generate calls that go nowhere.
-
8Conversion counted at the form, not at the booked survey
If Google counts a conversion the moment someone submits a form, your bidding algorithm will chase form fills, not real demand. Set up a second, more meaningful conversion action for a confirmed site survey, and watch how differently the keyword report reads once it's optimising toward that instead.
-
9No offline conversion import from signed job back to the ad account
A survey that turns into a quote that turns into a signed job weeks later is the actual outcome you care about, but Google Ads has no idea that happened unless you tell it. Importing offline conversions lets the account learn from real revenue instead of a vanity count of form submissions.
-
10Google Business Profile neglected while "intercom repair near me" spikes
A lot of emergency repair searches convert straight off the map pack before anyone clicks a paid ad at all. If your profile's opening hours, service area, and recent reviews aren't current, you're losing jobs to a competitor who simply answered that search better, not cheaper.
-
11Targeting radius wider than your engineers can actually reach
Bidding across an entire county because the targeting box was never tightened means you're paying for clicks from postcodes you can't service same-day. Match the radius to real travel time for your van team, not an optimistic guess at coverage.
-
12No nurture sequence for the managing agents comparing three quotes
A homeowner replacing a broken buzzer decides in a day. A managing agent tendering a maintenance contract across several blocks takes weeks and talks to two other installers in the meantime. If your only follow-up after a quote is silence, you're relying entirely on being remembered.
How to score each line, and which fails to fix first
Go through the twelve points above and mark each one pass, weak, or fail. Pass means you could show a stranger the evidence right now: a screenshot, a report, a working form. Weak means it technically exists but you wouldn’t bet money on it. Fail means it’s either missing or actively working against you. Most accounts we look at land somewhere around four passes, five weak, and three outright fails, and the fails are rarely where the owner expected.
Not every fail deserves equal urgency. Fix tracking before you touch scale: if items 7, 8, and 9 are weak or failing, every other decision you make is built on bad data, and adding budget just multiplies the noise. Fix intent before budget: items 1, 3, and 4 are about making sure the right searcher sees the right message, and no amount of extra spend compensates for the wrong ad copy reaching the wrong buyer. Fix speed before creative: if item 6 is failing, a better headline or a new offer won’t matter, because the visitor never gets far enough to read it.
There’s a reason this order matters more than it seems. Plenty of agencies will tell an intercom company to run more ads, test new copy, or raise bids when the account looks underpowered. That advice is nearly always wrong if the tracking underneath is broken, because you’ll be optimising toward numbers that don’t reflect what actually happened on site. Get the plumbing right first, even though it’s the least exciting work on the list, and the campaigns you already have will start performing differently before you spend another pound on reach.
If you want a second pair of eyes on the landing page itself rather than just the campaign settings, our HeyLead Insights team can show you exactly where visitors stall on a survey booking form, scroll past the pricing section without reading it, or abandon halfway through typing a postcode. Reading that behaviour tends to settle arguments about which page needs fixing first a lot faster than guessing.

The 30-day repair order
This isn’t a new strategy. It’s the order we’d work through the list above if we inherited your account tomorrow, starting with the items that corrupt everything downstream and ending with the ones that only matter once the foundation is solid.
30-day fix plan
- 1Set up a second conversion action for "survey booked," separate from the form submission, and tell Smart Bidding to optimise toward it once you've got a week or two of data.
- 2Add call tracking and WhatsApp tagging so every enquiry channel reports back to the keyword and campaign that produced it, not just "website" or "phone."
- 3Split your residential and commercial traffic into separate campaigns, even if it means pausing the combined one for a day while you rebuild it.
- 4Pull the last 60 days of search terms, sort by spend, and build a negative list that strips out DIY, careers, and pure model-number research.
- 5Build or rebuild dedicated landing pages for your two or three highest-volume system types, each with a price range, a photo of the finished install, and a survey form above the fold.
- 6Test the mobile booking form on an actual phone on a 4G connection, not a desktop browser resized smaller, and fix whatever takes more than a couple of seconds to appear.
- 7Set up offline conversion import so a signed job, even one that closes six weeks after the first click, feeds back into the account and teaches it what a real customer looks like.
DIY tools for this section
If reading through that list makes you want to hand it to someone and have it actually happen rather than sit in a spreadsheet, that’s a reasonable reaction. Running this properly across campaign structure, landing pages, and tracking at the same time is close to a part-time job on top of running the business. Our Google Ads management team builds and maintains exactly this kind of account for trades businesses, so the fixes above happen on a schedule instead of whenever there’s a spare afternoon.

What intercom company owners say when the leads stop converting
“We’d get a call from a managing agent two months after they first enquired, and nobody on our side could say whether that lead ever came from the Google account or just found us on the council’s approved contractor list. We were paying for clicks and had no idea if they were the reason the phone rang.”

FAQ
Do I need separate campaigns for residential and commercial intercom work? Yes, in almost every case. The buyers have different timelines, different decision-makers, and different proof they need to see before they’ll call, and bidding them together usually means your budget quietly favours whichever group clicks more often, not whichever group is more profitable to win.
Should my ad prices include VAT? If you’re advertising to homeowners, the price shown should include VAT. If you’re targeting managing agents, facilities managers, or other commercial clients, it’s standard to show prices excluding VAT and add it separately. Mixing the two on the same page is where most of the confusion, and the abandoned quote forms, come from.
How long before Google Ads shows a real return for an intercom business? Expect the first month to be mostly data collection and cleanup, especially if tracking wasn’t set up properly before. Most accounts we work on start showing a clearer picture of which keywords actually produce booked jobs, rather than just form fills, somewhere around the eight to twelve week mark, once there’s enough offline conversion data flowing back in.
What’s the single most common mistake you see in intercom company accounts? Counting every form submission as a win. A homeowner filling in a form to get a rough price and a managing agent submitting a tender enquiry look identical in most dashboards, but they’re worth completely different amounts, and treating them the same teaches your bidding to chase the wrong one.
Is it worth running ads for “intercom repair near me” if my Google Business Profile already ranks well organically? Usually yes, because the map pack and the paid ad occupy different space on the results page, and for an urgent repair search, most people click whichever answer looks fastest. If your profile is strong but your ad copy is weak, you’re still losing some of that traffic to a competitor’s better-written ad.
Putting it to work
Start this week by pulling the last 60 days of your Google Ads search terms report and tagging each one by intent: install, repair, maintenance contract, or none of the above. It takes about an hour for most accounts and tells you more about where your budget is actually going than a month of watching the dashboard. If a third or more of your spend sits in the “none of the above” column, you’ve found your first fix before you’ve spent a penny more.
The gap between a lead that looks like a win in Google Ads and one that actually turns into a booked survey and a signed job is exactly the kind of ongoing, detail-heavy work HeyLead takes off an intercom company’s plate, from campaign structure and tracking through to the landing pages that have to hold up once the click lands.
