Telecoms and utilities brands running Google Ads for broadband, energy and mobile switching campaigns are increasingly flooded with spam leads that look like genuine sign-ups until a sales rep tries to call the number back. Invalid traffic on Google Ads is a big part of why: fake form fills, bot-driven clicks and automated sign-up attempts inflate lead volume without adding a single real customer to the pipeline. This page looks specifically at how that shows up for telecoms and utilities advertisers and what to do about it.

Why Are Switching and Sign-Up Leads From Google Ads So Often Fake for Telecoms and Utilities Brands?

Telecoms and utilities sign-up forms ask for exactly the data bots are built to fabricate: a name, a postcode and a service address, with no payment step to filter out fake submissions. That combination makes broadband switching, energy quote and mobile contract campaigns an easy target for automated form fills.

Per Lunio's 2026 Global Invalid Traffic Report, telecoms and utilities advertisers see an average invalid traffic rate of 14.26% across their paid ad clicks. Quote and switch forms put little friction in front of bots, click farms and competitor click activity. Lead-gen KPIs like cost-per-qualified-switch get skewed when a meaningful share of "sign-ups" never had a working phone number in the first place. That pattern is covered in more depth in Lunio's click fraud statistics by industry.

How Do You Tell a Real Quote Request From a Spam Lead in Google Ads?

The clearest signs sit in the gap between what Google Ads reports as a conversion and what your CRM shows once a rep follows up: mismatched phone numbers, repeated postcodes across unrelated leads and sign-up timestamps clustered outside normal hours. None of these show up in standard conversion counts on their own.

The table below maps the signals telecoms and utilities marketers should check against where they actually surface inside Google Ads.

Which Google Ads Campaign Types Put Telecoms and Utilities Budgets Most at Risk?

Performance Max and Display-inclusive campaigns carry more exposure than Search alone, because they extend quote-request ads across automated placements with far less visibility into where a click actually came from. Search is not risk-free either. Broadband and energy keywords are high-CPC targets for deliberate competitor click activity. The mechanics behind how Google Ads handles these clicks, including how Google classifies invalid clicks, are covered in Lunio's Google Ads spam leads guide.

Telecoms and utilities advertisers running parallel campaigns on Microsoft Ads spam leads in telecoms and utilities or Meta Ads spam leads in telecoms and utilities tend to see the same fake switching and sign-up patterns, just surfacing through different placements.

How Lunio Helps Telecoms and Utilities Advertisers Cut Spam Leads on Google Ads

Lunio monitors the ad clicks behind telecoms and utilities quote-request and switching campaigns on Google Ads, removing invalid traffic before it reaches a CRM or distorts bidding data. In a case study from Culligan Harvey, a UK water treatment manufacturer, not a telecoms or utilities company but a comparable lead-gen advertiser, Lunio lifted Lead-to-MQL rate by 10% within the first month and cut invalid traffic by 54% across Google Search, Performance Max and Meta.

FAQ

Do spam leads from Google Ads show up as conversions in Google Ads reporting?

Yes. If a bot or low-quality form-fill completes a telecoms or utilities sign-up form, Google Ads typically logs it as a conversion. That means switching or quote-request conversion counts can look healthy while sales teams are chasing contact details that never connect.

Why do energy and broadband switching campaigns attract more fake leads than other Google Ads campaigns?

Switching and quote forms ask for basic contact details with no payment step, which makes them cheap and fast for bots or click farms to complete. Combined with high cost-per-click on competitive broadband and energy terms, this makes these campaigns a more attractive target than lower-CPC, higher-friction forms.

How does Lunio help telecoms and utilities advertisers with spam leads on Google Ads?

Lunio reviews the ad clicks entering telecoms and utilities Google Ads campaigns and removes invalid traffic before it inflates MQL counts or trains automated bidding on fake sign-ups. It does not screen native lead-form content itself. It works on the click traffic that reaches the advertiser's site or landing page.
