Google Ads vs Facebook ads: which is better for affiliates

Google Ads catches people who are already searching; Meta builds demand with creative. How cost, tracking and gambling rules differ, and which offers suit each.

In the Google Ads vs Facebook ads choice, affiliates should start from intent. Google Ads reaches people already searching, which suits high-intent verticals such as finance, betting and crypto, where Google checks compliance first. Meta's Facebook and Instagram ads create demand through creative, which suits visual, impulse offers. A common pattern is to start on one and add the other.

Audience size rarely decides it. The vertical, platform approval, the event your program pays on and your tracking set-up do. Policies checked October 2026.

Search intent vs social demand: how each platform works for an affiliate

Google vs Facebook ads comes down to whether you answer demand that already exists or build it from nothing. On Google, the query tells you what the person wants. On Meta, the delivery system picks who might want your offer before they ask.

Google Ads (formerly AdWords, renamed in 2018) sells text ads on Google Search results, plus Display, YouTube video, Shopping and App campaigns. Performance Max is a goal-based campaign that buys across all Google inventory from one setup, and Demand Gen runs visual ads on YouTube, Shorts, Discover, Gmail, Maps and the Display Network. For most affiliates the core is still Search: you pick the queries, such as sportsbook promos in a licensed state, and the click arrives with a stated need.

Meta ads run on Facebook, Instagram, Messenger, WhatsApp, Threads and the Audience Network, with placements depending on the campaign objective. There is no query to bid on: you supply creative and a conversion signal, and the system finds the people. Since Meta rebuilt ad retrieval around Andromeda, the creative itself carries much of the targeting, so the work is producing distinct angles and feeding clean conversion data back.

Google wins on intent and predictability, Meta on reach and creative leverage; both are strict with regulated offers.

Cost: CPC vs CPM and why neither is "cheaper"

Neither platform is cheaper by default, because they price different things: Google Search mostly charges per click, Meta mostly bills on impressions. On Google Search you set a maximum cost per click, and Google says the actual charge is often lower. Bid strategies such as Target CPA and Target ROAS let Google set bids toward conversions instead.

On Meta, the event you are charged for depends on the campaign objective. Impressions are the billing event available across every buying type, and some objectives allow paying per link click instead. Comparing a Google CPC with a Meta CPM therefore compares two different units.

The useful comparison of Google Ads vs Facebook ads cost is cost per paid conversion (first deposit, approved lead or sale) against what your program pays for it. We quote no benchmark CPCs or CPMs because they swing with geo, vertical and season. For Meta's pricing drivers, see how much Facebook ads cost.

Tracking and attribution

Both platforms tag the click, and an affiliate has to carry that tag through someone else's site. Google's auto-tagging appends a gclid (Google Click Identifier) to the landing URL. Meta appends fbclid; the Meta Pixel stores it in the _fbc cookie, and Meta asks advertisers to send the matching fbc value with every Conversions API event.

The affiliate's problem is that the conversion happens on the operator's or merchant's site. The usual set-up stores the click ID in a tracker subid, receives the program's postback when the player deposits or the lead is approved, and reports that conversion back to each ad platform. Without that loop, both platforms optimize toward clicks instead of revenue. Keep UTM parameters and naming identical on both.

Gambling and regulated offers on each platform

Both platforms allow gambling ads only from approved advertisers, and both apply the rule to affiliate sites. Rules checked October 2026.

Google Ads requires certification from Google before any gambling ad runs, with a valid local licence for each country targeted and a separate application per country. In the United States the policy permits ads for lotteries, horse racing, lottery couriers, sports betting and online casinos. Horse racing, sports betting and online casino advertisers must hold a state licence where the state requires one, may not target anyone under 21 or anyone outside the states they are licensed in, and must show a compulsive-gambling warning with help information in the ad or on the landing page. Affiliate and comparison sites are allowed if they inform or compare and do not offer gambling themselves. They can target only the US states listed in their certification and must link only to operators licensed in the targeted area.

Meta allows online gambling and gaming ads only once the ad account holds Meta's authorization, requested in Meta Business Suite with evidence that the activity is licensed or lawful in each territory targeted. The policy names landing pages that promote gambling "such as aggregator or affiliate sites", so a review site does not escape it. Ads may not target under-18s, and some markets are closed entirely. Sweepstakes are listed as a form of gambling. Free social casino games with no chance to win money or anything of value follow a separate, narrower set of rules on Meta (adults only, listed countries), and Google does not let affiliate or aggregator content promote them; see what a social casino is.

For affiliates, approval is a business gate, not a setting. Both platforms review the business behind the account, several US states also make affiliates register or hold a licence, and Google warns that serving gambling ads without certification can get an account barred from advertising. Without that approval, an affiliate cannot run operator offers on either platform. This is a summary of platform policies, not legal advice.

Which is better for affiliates? Verticals and budgets

Google is better when people already search for the offer; Meta is better when the offer has to be sold with an image, a video or a story. For some offers, approval decides the channel before demand does. The grouping below is the common view among media buyers, not a platform rule.

The offer has search demand: usually Google first

  • Finance: the buyer is already comparing options, so a query for a card or a quote is the conversion moment. Google requires financial services verification in some countries.

  • Product reviews: the query names the product, and a review page answers it.

The offer needs a visual story: usually Meta first

  • Nutra: the offer works only if the ad makes a claim believable, and Meta's Health and Wellness rules cap that claim: weight-loss ads go to adults only, sensational health claims are banned.

  • Dating and social apps: the sale is a feeling a short video can show, and branded searches for a single dating offer are rare.

  • Apps and casual games: a few seconds of gameplay demonstrate the product better than any text ad can.

The offer needs approval first: get it before you budget

  • Regulated betting and casino: search intent is high, but Google sells it only to certified advertisers in licensed states, and Meta needs its own authorization. The platform that approves you is the one you can test.

  • Crypto exchanges: for US exchange ads Google requires certification and accepts only FinCEN-registered money services businesses that are also state money transmitters, or chartered banks. Meta needs written permission backed by a licence from its country list.

Budget and skill set the threshold too. On Google the core skill is keyword, match-type and bid management. Google's "Learning" status after a major change lasts no more than seven days, though performance can take one or two conversion cycles to settle. Meta needs creative volume plus enough conversions to learn: its Help Center marks an ad set "learning limited" when it is unlikely to collect enough optimization events, a working figure being around 50 in the week after a significant edit. With a small budget and a costly event such as a first deposit, buyers often optimize toward a more frequent event such as a registration.

The verdict: if your offer has search demand and you can pass the compliance gate, start with Google. If it has no search demand but a strong visual hook, and Meta will approve it, start with Meta ads.

How to use both together

Running both works best when each channel has one job and one tracker judges them. Search answers people comparing offers or looking for a review, plus brand terms where your program allows it (many restrict brand bidding). Meta reaches people who have not heard of the offer yet, and both can retarget visitors who clicked but did not convert. For a like-for-like test of Meta prospecting, run Demand Gen, Google's visual prospecting product, against Meta.

Keep one conversion definition and one tracker, and compare the channels on cost per paid conversion, not on platform-reported numbers that each count differently. In our view, make one channel profitable before adding the second.

The same order applies to a third channel such as TikTok, Reddit or Microsoft Advertising: add it only after one of the first two pays.

FAQ

Which is better, Google Ads or Facebook ads, for affiliates?

Google Ads is better for affiliates whose offers people already search for, such as finance, regulated betting and crypto, once the account is approved. Meta is better for offers sold on creative, such as dating, apps and nutra.

Which is cheaper, Google Ads or Facebook ads?

Neither Google Ads nor Facebook ads is cheaper by default. Google Search usually charges per click and Meta usually bills on impressions, so compare cost per paid conversion against your payout. See how much Facebook ads cost for Meta's price drivers.

Is it worth running ads on Facebook?

Running ads on Facebook is worth it when you need to create demand, can supply fresh creative and send conversions back through the Pixel and Conversions API. It is not worth it for offers Meta will not approve.

How much do 1,000 clicks cost on Facebook?

The cost of 1,000 Facebook clicks has no fixed figure: most Meta delivery is billed on impressions, and click cost depends on geo, placement, audience, creative and season. A small test on your own offer gives the only reliable number.

Can affiliates run gambling ads on Google or Meta?

Only after approval. Google requires certification and, in the US, targeting limited to the states in that certification; Meta requires authorization with evidence that the gambling is licensed or lawful in each territory.

Should I run Google Ads and Facebook ads at the same time?

Running Google Ads and Facebook ads at the same time works once one channel is profitable. Starting both at once tends to split a test budget too thinly for either to learn.
