Facebook Ads vs Google Ads: which to run first

Facebook Ads vs Google Ads comes down to where the demand is. On Google Search, the person has typed what they want and the ad competes to answer; Google Ads Help describes Ad Rank as deciding whether and where an ad shows for that search from the bid, the quality of the ad and landing page, the thresholds, the competition and the context of the query. The platform sells an answer to a stated need, which is why Search clicks cost more and convert at a high rate.

On Facebook and Instagram nobody asked. Meta's own description of its delivery system says it ranks ads by total value, the bid multiplied by the estimated action rate for this person, plus ad quality. The system predicts who is likely to act and shows your ad to them in a feed, among friends and creators. The ad has to create the want before it can collect it, which is why the creative, not the keyword, does the targeting.

The answer to which to run first follows from that. If people already search for what you sell, capture that demand first, because it is the cheapest conversion you will ever buy. If they do not, because the product is new, impulsive or visual, create demand first, and let the branded searches it produces be your reason to add Google later.

LocaliQ, with WordStream, publishes benchmarks for both platforms from its customers' accounts, which makes a same-year comparison possible. In its 2026 reports a Facebook lead campaign click costs $1.80 on average and a Search click $5.42, three times more. Facebook's CTR on lead campaigns is 2.70% against 6.64% on Search, and the two convert clicks at almost the same rate, 8.54% on Facebook against 8.18% on Google. The cost per lead lands at $27.39 on Facebook and $66.69 on Search.

Read the gap carefully. The Facebook lead usually comes from an instant form filled in the feed, by someone who was not looking; the Search lead typed the need. A cheaper lead that the sales team cannot reach is not cheaper. The only comparison that holds is cost per qualified lead or cost per order, measured in your CRM or your store, for the same month.

For ecommerce the two platforms are not even priced in the same unit. Meta is bought per thousand impressions: Databox's October 2026 median CPM is $7.26 across 2,800 companies of every objective, and Lebesgue's 2026 figure for US ecommerce audiences is $16.08. Google Search is bought per click, and Shopping clicks for European retailers cleared at a 0.36 euro median in Smarter Ecommerce's September 2026 data, against 0.43 euros for Search and 0.41 for Performance Max. The cost guides for each platform on this blog go through these figures by industry.

Facebook and Instagram win when the product is new, visual or impulsive, and when the buyer can be described better than the search can. A food brand, a fashion label, a gadget or a course rarely has search volume before it has customers; a short video in Reels can show the product in use to people who did not know it existed, and Meta's delivery system learns which of them buy.

They also win on volume at the top of the funnel and on retargeting. The people who visited your site, watched your video or bought once are an audience you can reach again, and lookalikes of your customers extend it. For lead generation, instant forms remove the landing page and produce leads at $27.39 on average in LocaliQ's 2026 data, which suits a business whose sales team qualifies by phone.

The price is creative. Because the creative does the targeting, it wears out, and a Meta account that works has a pipeline of new images and video rather than a set of keywords. The creative fatigue guide on this blog covers how to see that happening before the cost per result tells you.

• New products and categories with no search volume yet
• Visual products that sell in a video
• Retargeting and lookalikes of existing customers
• High-volume B2C leads that a sales team qualifies

Google Ads wins whenever the customer can describe the need in words: a plumber in a named town, a CRM for small teams, a running shoe by model name, a flight to a city. Search converts those clicks at 8.18% on average in LocaliQ's 2026 benchmarks, and the lead is someone who asked. For a business with a sales cycle, a $66.69 lead that requested a demo can be worth several cheaper ones that filled a form on impulse.

Google also wins on the catalog. Shopping shows the product, its price and the store before the click, so the click already compares prices, and Performance Max extends the same feed across YouTube, Display, Search, Discover, Gmail and Maps from one campaign once there is conversion data to learn from. Local businesses get location targeting and call assets built for the job.

The limit is volume. Search can only capture the demand that exists; when every relevant query is already bought, the next dollar raises your bid against the same competitors rather than finding new customers. That is the point at which a Google-first business adds Meta, to create the demand Search will later capture.

• Services and software people search for by name or category
• Known product categories, through Shopping
• Local services with a town in the query
• Branded search, to protect the demand your other channels created

The trail table applies the rule to six kinds of business. An ecommerce store with a new or impulse product starts on Facebook and Instagram and adds Search and Shopping when branded searches appear. A store in a known category starts on Shopping, where European retailers paid a 0.36 euro median per click in September 2026, and adds Meta when Shopping ROAS is stable and new customers, not just searchers, are the goal.

SaaS and local services start on Search, because the query carries the intent and the budget is spent on people who asked, and add Meta when search volume is exhausted or for retargeting and lookalikes of customers. Mobile apps and B2C lead generation start on Facebook and Instagram, where app promotion campaigns and instant forms reach people at volume, and add Google when the brand has earned searches of its own.

Two exceptions are worth naming. A business with a small budget and real search demand should still start on Search, however cheap the Facebook click looks, because the first conversions arrive faster from people who are looking. A business with no search demand and no creative should fix the creative before it buys any media on either platform.

The two platforms ask for different volumes before their delivery systems stabilize, and the first budget should be sized to reach them. Meta's learning limited help page says an ad set is marked learning limited when it is unlikely to receive around 50 optimization events in the week after its last significant edit. At LocaliQ's 2026 average cost per lead of $27.39, one ad set optimized for leads needs about $1,370 a week, roughly $5,900 a month, to be judged.

Google Ads Help recommends judging a Smart Bidding strategy over a period with at least 30 conversions, such as a month, or 50 for Target ROAS, and says the learning period usually lasts one to two conversion cycles. At the 2026 average cost per lead of $66.69, that is about $2,000 a month for a Search campaign, with the monthly charge capped by Google at 30.4 times the average daily budget.

So Google's cheaper-looking test is the Search campaign, even though its lead costs more: fewer conversions are needed and each one is someone who searched. Meta's threshold is higher in events, and it is per ad set, which is why a Meta test runs one ad set, not five. Running both on budgets that reach neither threshold is the most common way to conclude that neither platform works.

• Meta: about 50 events per ad set per week, so one ad set per test
• Google: at least 30 conversions, such as a month, per bid strategy
• Size the first budget to the threshold, not to a share of revenue
• Optimize for an earlier event when 50 purchases a week is out of reach

Once both run, each platform reports the conversions it attributes to itself, under its own window and model, and the two totals usually add up to more orders than the store recorded. The only honest read is spend on both platforms against the revenue the store or the billing tool recorded for the same dates: blended ROAS, or the marketing efficiency ratio when all marketing cost is counted. In Adrails, Analysis shows Meta, Google Ads, Shopify and Triple Whale each on its own row for the same period, with ad spend, revenue, ROAS and results in the cards, and Meta and Google Ads items can be compared together over the same dates; new Google Ads connections open once Google finishes verifying Adrails, so connect Meta now and add Google Ads when your workspace can.

If people search for what you sell, start on Google Search, or Shopping for a catalog, and size the first month at 30 times your target cost per lead. If they do not, start on Facebook and Instagram with one ad set sized at 50 times your target cost per result per week, and a pipeline of creative behind it. Judge neither before its threshold.

Add the second platform when the first has a measured cost per result to beat: branded search appearing for a Meta-first business, search volume exhausted for a Google-first one. From then on, move budget between them on blended ROAS or MER against your break-even, never on each platform's own ROAS, and let the platform whose marginal order is cheaper take the next dollar.
