Facebook Ads vs Google Ads: which should you run first?
A practical comparison from Saifur Saif, a Google Ads & Meta Ads Specialist whose campaigns have generated $25M+ in sales, with current benchmark data and a simple way to decide.

Short answer
Google Ads captures demand: ads appear when people search for what you sell, so intent is high and clicks cost more. Facebook Ads (with Instagram, run from Meta Ads Manager) create demand: ads reach people by interest and behaviour before they search, so clicks are cheaper but intent is lower. If people already search for your product or service, start with Google Ads. If your product is new, visual or easy to buy on impulse, start with Facebook and Instagram Ads. Most growing brands end up running both, measured with the same tracking.
The real difference: intent
The question is not which platform is better, but where your customers are in their decision. Someone typing “emergency plumber near me” into Google wants to buy now. Someone scrolling Instagram was not looking for anything, but may stop for the right product shown the right way.
That single difference explains most of the numbers. Google Ads clicks cost more because the person is closer to buying. Facebook Ads clicks cost less because you are interrupting people, and more of them need time, retargeting or a stronger offer before they buy.
Why cheaper clicks do not always mean cheaper customers
In the latest US benchmarks, the median Facebook Ads cost per click for lead campaigns was $1.80, against $5.42 for Google search ads. But what matters is the cost of a customer, not a click. A Google click from a high-intent search can convert several times better, and a Facebook lead can be cheaper but less qualified. That is why both platforms should be judged on cost per sale or qualified lead, using accurate conversion tracking.
What decides results on each platform
On Google Ads, results are driven by keyword and search term control, bidding, product feed quality for Shopping, and landing page relevance. On Facebook Ads, results are driven mostly by creative and offer: with broad audiences and Advantage+ campaigns, the ad itself decides who sees it. On both, the algorithm can only optimise toward what it is told, so the Google tag and enhanced conversions, and the Meta Pixel with the Conversions API, come first.

Which one should you start with?
Quick verdicts by business type.
Local services
Start with Google Ads. People search when they need a plumber, dentist or lawyer, and local search intent converts well.
New or unique products
Start with Facebook Ads. If nobody searches for your product yet, you need to create demand in the feed.
Lead generation
Google Ads for high-intent enquiries; Facebook lead forms for volume at a lower cost, with CRM tracking to protect quality.
B2B and SaaS
Google Ads for people searching for a solution, supported by retargeting. LinkedIn Ads can add job-title targeting.
Small budgets
Pick one platform and do it properly. Splitting a small budget across both rarely gives either enough data to learn.
How to run Facebook Ads and Google Ads together
The two platforms work best as one system. Facebook and Instagram Ads introduce your brand to new people; some of them later search for you on Google, where branded and category search campaigns capture the sale. Retargeting on both platforms brings back visitors who did not buy the first time.
To make that work, use the same conversion definitions on both platforms, compare results in one dashboard, and judge each platform on blended numbers such as total revenue against total ad spend, as well as on its own reported results. Start with the platform that matches your demand, get tracking right, then add the second once the first is profitable.

Facebook Ads vs Google Ads FAQs
Straight answers to the questions business owners ask most.
Is Facebook Ads cheaper than Google Ads?
Per click, usually yes. In the 2026 US benchmarks the median Facebook lead campaign cost per click was $1.80 against $5.42 for Google search. But Google traffic often converts better, so compare cost per sale or qualified lead, not cost per click.
Which has better ROI, Facebook Ads or Google Ads?
Neither wins everywhere. Google Ads tends to win when people already search for your offer; Facebook Ads tends to win for visual, new or impulse products. The best ROI usually comes from running both with shared tracking.
Can I run both with a small budget?
It is usually better to start with one platform, prove it is profitable, then add the second. A small budget split two ways often leaves both campaigns without enough data to optimise.
Are Instagram Ads part of Facebook Ads?
Yes. Facebook and Instagram Ads are both run from Meta Ads Manager, using the same audiences, Pixel and Conversions API. Placements such as Reels and Stories need their own creative.
Which is better for eCommerce?
Most online stores need both: Google Shopping and Performance Max for people searching for products, and Facebook and Instagram Ads for discovery and retargeting.
Which is better for local businesses?
Google Ads usually comes first, because people search when they need a local service. Facebook Ads can add awareness and offers for restaurants, gyms, clinics and shops.
