Sorting Through the PPC Platform Noise

Every platform claims to be the best for PPC campaigns, yet market share numbers conflict depending on who's counting — Google Ads ranges from 62% to 73% of global paid search revenue across sources, Amazon Ads holds 14% by revenue, and Facebook leads in advertiser adoption at 76%. For service businesses like HVAC, dental, and legal, this confusion is costly: legal clicks average $8.94 CPC, and roofing leads can reach $228.15 CPL, making platform choice critical before spending a dollar. The real problem isn't just picking a channel — it's ensuring leads don't vanish after the click, since slow or missed responses lose intent regardless of where the ad ran.

Google Ads remains the dominant platform for most advertisers, capturing 47% of budgets allocated to Google Search alone and powering the highest-intent leads across industries by targeting active search queries. Microsoft Ads, meanwhile, is consistently identified as an undervalued opportunity — only 6% of paid search budgets go to Bing despite 33% lower CPCs than Google ($1.54 vs. $2.96) and comparable conversion rates, making it a high-ROI channel especially for B2B and affluent audiences. For home services specifically, Google Ads plus Microsoft Ads and Google Local Services Ads form the practical default, as LocaliQ's benchmarks are based solely on these platforms to manage CPL volatility in verticals where costs are rising for 75% of businesses.

• Google Ads controls 62–73% of global PPC revenue depending on methodology, with Amazon second by revenue (14%) and Facebook second by advertiser adoption (76%)
• Legal services face the highest average CPC of any industry at $8.94, while roofing CPLs average $228.15 — among the highest in home services
• Microsoft Ads delivers 33% lower CPCs than Google Search with comparable conversion rates, yet receives only 6% of paid search budgets

Critically, multiple sources confirm the money leaks after the click — dental call paths lose roughly a third of intent, and insurance converts at just 2.64% despite the industry's highest CTR of 9.83%. This post-click problem is where CallMyLeads intervenes: every new lead from forms, ads, chat, referrals, or missed calls gets an instant response in seconds, 24/7/365, ensuring interest doesn't disappear before a human or AI can engage. For service businesses fighting high CPCs and CPLs, fixing the response path isn't optional — it's the difference between paying for clicks and booking jobs.

The Data: Google Ads Leads, and It's Not Close

Ask ten marketers which PPC platform they use most, and nine of them will give you the same answer. Google Ads dominates pay-per-click advertising so thoroughly that the real question isn't who's #1 — it's how far the gap stretches.

The numbers vary depending on who's counting. One industry analysis puts Google's share of global paid search revenue at 62%, with 47% of advertiser budgets flowing to Google Search alone. Another estimate places Google's control of the broader PPC market at 69%, while a third source claims over 73%. The honest answer: somewhere between 62% and 73%, and no other platform comes close.

The #2 spot is where it gets interesting, because the answer depends on your metric:

• By revenue: Amazon Ads holds second place at 14% of global PPC revenue, with a 9.47% average conversion rate — roughly 3x higher than Google Search.
• By adoption: Facebook is the second most used platform, with 76% of PPC marketers running campaigns there.
• By budget share: Microsoft/Bing gets just 6% of paid search budgets despite 33% lower CPCs than Google.

So what does market share actually mean for your budget? Less than you might think. Google's dominance reflects where buyers search, not where every dollar works hardest. For service businesses — HVAC, dental, legal — Google Ads plus Microsoft Ads and Local Services Ads remain the practical default, according to LocaliQ's home services benchmarks. But costs are climbing: CPCs rose for 75% of home services businesses, and cost per lead jumped for 69%.

Here's the part market share charts won't tell you: the platform you pick matters less than what happens after the click. As one agency case study bluntly puts it, "The dental ad account is rarely the problem. The phone is." Insurance search, for instance, has the highest click-through rate of any vertical at 9.83% but nearly the lowest conversion at 2.64% — the money leaks after the click. That's why at CallMyLeads, we focus on what happens once the lead arrives: a response in seconds, every time, before interest cools.

Choose your platform based on intent and industry, then protect the lead path with everything you've got. If you're ready to stop paying for leads you never get to talk to, get every lead answered in seconds, 24/7/365.

The Platforms That Matter for Service Businesses

For home services, dental, and legal firms, the platform decision is practically made for you. LocaliQ's benchmarks for these verticals are built entirely on Google Ads and Microsoft Ads campaigns, with Google Local Services Ads (LSAs) layered on top to stabilize cost per lead. Legal carries the highest average CPC of any industry at $8.94, while roofing leads can exceed $228 each — so every click needs to count.

• Google Ads + LSAs capture active search intent and deliver the highest-intent leads across nearly every service category
• Microsoft Ads offers 33% lower CPCs ($1.54 vs. $2.96) with comparable conversion rates and an audience where 46% of households earn over $100K
• AI search advertising generated $500M+ in 2026 and is projected to hit $4.2B by 2028, with early ads seeing 2.4× higher engagement than traditional search

The data shows most advertisers are over-concentrated on Google Search, with a 16% average budget shift toward other channels last year. Bing remains the consensus undervalued channel — only 6% of paid search budgets go there despite 26% lower CPA for B2B verticals. Meanwhile, AI Overviews now appear on 37% of Google queries and have already caused an 18% CTR decline for ads below them, reframing Google as a bottom-funnel conversion tool rather than a top-funnel awareness driver.

This platform mix only works if the response side keeps up. Agency case studies show dental call paths lose roughly a third of buy intent, and insurance converts at just 2.64% despite the highest CTR of any vertical — the money leaks after the click. CallMyLeads plugs that leak by answering every lead in seconds, 24/7/365, so the platform spend you just optimized actually turns into booked jobs.

The Leak That Costs More Than Your Platform Choice

Here's the uncomfortable truth from the data: your choice of PPC platform probably isn't what's costing you money. Multiple sources in this research point to the same conclusion — the leak happens after the click, not at the ad level.

Consider insurance. According to agency case studies, insurance search ads earn the highest click-through rate of any vertical at 9.83% — yet convert at nearly the lowest rate, just 2.64%. The ads work. People click. Then the money leaks after the click, somewhere between the ad and a signed policy.

Dental tells the same story. The same research puts it bluntly: "The dental ad account is rarely the problem. The phone is. Buy intent correctly, then fix the call path that loses a third of it." Roughly a third of buying intent disappears in the call path — missed calls, slow callbacks, voicemail that never gets checked.

No platform choice fixes that. Switching from Google to Bing, or from Meta to Amazon, doesn't make anyone answer the phone faster. And the stakes keep rising: LocaliQ's benchmarks show CPCs increased for 75% of home services businesses, with cost per lead up an average of 10.51% year over year. You're paying more for every lead you fail to reach.

The pattern shows up across verticals:

• Insurance: highest CTR of any vertical (9.83%), but only 2.64% conversion
• Dental: about a third of buying intent lost in the call path
• Home services: rising CPCs mean every missed lead costs more than it did last year

This is why response speed beats platform choice for service businesses. The lead that gets a reply first usually wins — whether it came from Google Ads, Microsoft Ads, or a referral. A slow response on the "best" platform loses to a fast response on a mediocre one.

The practical fix is simple to describe and hard to staff: answer every lead in seconds, every hour of the year. Nights, weekends, holidays, peak season. For most businesses, that means either hiring two full-time people to cover the phones — or using a system like CallMyLeads, which answers every call, text, and form lead instantly, around the clock, and books the appointment before interest fades.

Because the most-used platform doesn't matter if nobody picks up. Pick your platform based on where your buyers search. Then make sure that when they click, someone — or something — is ready to respond before they move on to the next ad on the list.

Your Next Steps: Pick the Platform, Then Fix the Response

Picking the platform is the easy half. The hard half is what happens in the 60 seconds after someone clicks — because that's where most paid clicks quietly die.

Start with Google Ads, where intent is highest. Google captures 62–73% of global paid search revenue depending on the source, and it consistently produces the highest-intent leads across nearly every industry. For home services, dental, and legal readers, it's the default — even with legal CPCs averaging $8.94 and home services clicks running $7.85 on average.

Then test Microsoft Ads as a lower-cost complement. Only 6% of paid search budgets go to Bing, yet its CPCs run 33% cheaper than Google ($1.54 vs. $2.96) with comparable conversion rates. That gap makes it the most underspent high-ROI channel in PPC — a cheap way to add volume without raising your blended cost.

As you scale, fix your reporting before you fix your budget. One agency puts it plainly: stop reporting one blended cost per lead, and instead:

• Separate branded from non-branded search so you know what you're actually paying to win
• Add Local Services Ads underneath search campaigns
• Optimize to booked jobs instead of form fills — a form fill isn't revenue
• Track cost per booked job against benchmarks like $112–$216 for dental new patients or $330–$736 for HVAC

That last point matters more than it looks. The same agency found that dental ad accounts are rarely the problem — the phone is, with call paths losing roughly a third of buy intent. Insurance tells the same story: the highest click-through rate of any vertical at 9.83%, but a conversion rate of just 2.64%. The money leaks after the click.

This is why platform choice alone won't save your PPC. Costs are rising — CPC increased for 75% of home services businesses, and cost per lead climbed nearly 11% year over year — so every lead you pay for has to get answered, fast. The lead that gets a reply first usually wins, and nights, weekends, and peak-season calls don't wait for business hours.

That's the gap CallMyLeads closes. It's a done-for-you lead response and appointment-setting service that connects your forms, ads, phone lines, and chat to one system that answers every new lead in under 10 seconds — 24/7/365, with nothing going to voicemail. Response rules are set by you, bookings land in your calendar, and every lead is tracked from source to outcome. Your leads, your data, and your calendar stay yours.

So here's the plan: pick Google Ads for intent, layer in Microsoft Ads for efficiency, report on booked jobs — and make sure no paid click ever goes to waste.

Stop paying for leads you never get to talk to. Get every new lead answered in seconds, around the clock.
