Google Ads vs. Meta Ads: where should your budget go?

The split is demand capture vs. demand generation

Google Ads is demand capture. Someone types "kitchen remodeler near me" or "cost to finish a basement," and you put your offer in front of a homeowner who already decided they have the project. The intent is the targeting. You are competing for homeowners at the bottom of the funnel, which is why clicks cost more and convert faster.

Meta Ads is demand generation. Nobody opens Instagram to hire a contractor. You interrupt a scroll with a before-and-after they were not yet planning, then use audience signals and creative to build interest from cold to warm. Attention is cheaper because intent is lower. The trade is that Meta will not find demand that does not exist yet for your services, and a weak ad sinks the whole campaign.

What the numbers actually say

WordStream's 2025 benchmarks, drawn from 16,446 US search campaigns between April 2024 and March 2025, put the average Google Ads CPC at $5.26 and the average conversion rate at 7.52%, with an average cost per lead of $70.11. Costs climbed about 13% year over year, but conversion rates improved in 65% of industries, so the click got pricier and more productive at the same time.

Meta's lead-objective campaigns in the same WordStream dataset averaged a $1.92 CPC and a $27.66 cost per lead, with a 7.72% conversion rate. So Meta leads come in cheaper per record. The catch is quality: a Google lead usually raised a hand mid-search, while many Meta leads were nudged into a form they did not go looking for. Cheaper does not always mean better, and the gap shows up in close rates and sales-cycle length, not the ad dashboard.

On the high-intent end of B2B, Dreamdata's 2026 benchmarks put LinkedIn at 121% ROAS against Google Search at 67% and Meta at 51% for revenue-influenced spend. The pattern holds: the closer a channel sits to active buying intent, the better the return on each dollar, and the more it costs to get in front of that buyer.

Lead with Google when intent already exists

Pick Google as your primary channel when buyers describe your product in the search bar. High-ticket local services are the clearest case. Attorneys average an $8.58 CPC and dentists $7.85 in the 2025 benchmarks, and they still pay it, because one converted search can be worth thousands. If your category has a known search term and a quantifiable customer value, capture beats generation on day one.

Google also wins when your offer is hard to make visual or sits deep in a consideration cycle: legal help, B2B software, specialty medical, emergency trades, anything where a person is actively comparing providers. Search Ads, Local Services Ads, and retargeting against your search visitors (RLSA) let you bid up for people who already know you. The downside is a ceiling. Google can only sell to existing demand, so once you saturate the relevant queries, more budget buys diminishing returns.

Lead with Meta when you have to create the want

Pick Meta when demand is thin and your work earns attention on its own. A whole-home renovation reveal, a stunning custom build, a dramatic kitchen or bath before-and-after, and any project that looks great in a 15-second video all belong here. CPMs typically land in the $10 to $15 range for broad US audiences, so you can buy a lot of reach for a modest test budget and let the algorithm find homeowners.

On Meta, the creative is the targeting. Detailed interest options keep shrinking, and Advantage+ campaigns hand audience selection to the algorithm, so the ad does the heavy lifting. Plan to test 3 to 5 creative variants per ad set and refresh them on a schedule. Ads that run past three to four weeks without a refresh see materially higher CPMs and falling click-through as fatigue sets in. If you cannot produce a steady supply of new creative, Meta will underperform regardless of budget.

Meta's other quiet strength is retargeting. Warm-audience campaigns against website visitors, video viewers, and engagers routinely post the highest ROAS in the account, often near 4x, because you are reminding people who already showed interest rather than buying cold attention.

Most accounts should run both, in sequence

The two platforms compound. Meta builds awareness and seeds demand at the top; Google catches that demand when it converts into a search; retargeting on both closes the people who hesitated. Buyers do not stay on one platform, so splitting them weakens the funnel. A practical full-funnel split is roughly: prospecting on Meta to create interest, capture on Google for ready-to-buy queries, and 20% to 30% of budget reserved for retargeting across both.

Budget decides whether "run both" is realistic yet. Each platform's algorithm needs volume to learn. Google Smart Bidding wants roughly 30 conversions in 30 days per campaign; a Meta ad set needs about 50 conversions a week to exit the learning phase. Below that, the AI cannot find a pattern and performance stays noisy.

If your total monthly budget is under about $2,000, do not split it. Concentrate on the single platform that matches your intent profile, get one channel past its learning threshold, then expand to the second once the first is profitable and stable. WellBuilt runs paid media across Google and Meta together, sequencing the two so each platform does the job it is actually good at instead of forcing one to do both.

Measure the platforms on different yardsticks

Judging Meta by last-click conversions undersells it, and judging Google by impressions oversells it. Hold each to the metric that reflects its job. For Google, watch cost per qualified lead or sale and lead-to-close rate, since the value is intent quality. For Meta, watch blended ROAS, new-customer acquisition cost, and the lift in branded Google searches, since the value is demand you created upstream.

Track one number across both: blended customer acquisition cost against customer lifetime value. Platform dashboards both claim the same conversions and will not reconcile. A simple post-purchase "how did you hear about us" survey plus your own back-end revenue data will tell you more about the real split than either ad manager. Decide budget moves on the blended math, not on whichever platform reports the prettier in-app ROAS.
