Google Ads vs. Facebook Ads on a Tight Budget — Honest Breakdown After Spending $1,200 Testing Both

Alright, I promised myself I would share this once I had enough real data to make it worthwhile. Over the last four months I ran parallel tests on Google Ads and Facebook Ads for my small outdoor gear e-commerce store. Total budget split was roughly $600 on each platform. Here is exactly what I found.

The Setup

My store sells mid-range hiking and camping gear — average order value around $78. I targeted the continental US, ages 25-54, interest in outdoor recreation. Same products promoted on both platforms. I tracked everything through Google Analytics 4 with UTM parameters so there was no guessing.

Google Ads Results ($600 spent)

• Total clicks: 1,140
• Average CPC: $0.53
• Conversions: 19 sales
• Revenue generated: $1,482
• ROAS: 2.47x

Facebook Ads Results ($600 spent)

• Total clicks: 2,890
• Average CPC: $0.21
• Conversions: 11 sales
• Revenue generated: $858
• ROAS: 1.43x

My Takeaway

Facebook gave me way more clicks for the money, but Google converted significantly better. The people coming from Google were already searching for what I sell — they had purchase intent. Facebook traffic was browsing with curiosity at best.

That said, I think Facebook has real value for brand awareness and retargeting. Once I built a custom audience from Google-sourced visitors and retargeted them on Facebook, my Facebook ROAS jumped to 2.1x. The two platforms work better together than either does alone.

Would love to hear if anyone else has run similar tests. Especially curious whether product niche changes these numbers dramatically.

This is one of the most useful posts I have seen on this forum in a while, and your methodology is solid. UTM tracking plus GA4 is the right way to do this — too many people eyeball their ad dashboards and call it data.

A few things worth adding from my own experience managing campaigns for small e-commerce clients:

• Search intent is Google's unfair advantage. When someone types "best hiking boots under $100" they are 80% of the way to buying. Facebook users did not wake up wanting your product — you are interrupting their scroll.
• Your retargeting insight is the real gem here. This is called a multi-touch attribution strategy and it is what larger brands have been doing for years. Google captures intent, Facebook closes the deal or re-engages warm audiences.
• Watch your match types on Google. If you ran broad match keywords, your CPC and conversion data could look very different with phrase or exact match. Broad match can drain budget on irrelevant searches fast.

One question — did you use Shopping Ads or Search Ads on Google? Shopping tends to perform better for physical product e-commerce, and the visual format competes more directly with Facebook's visual nature.

This is so helpful, thank you EcomKing_Rex! I have been going back and forth on which platform to start with for my handmade jewelry shop and honestly I have been paralyzed by indecision for weeks.

Can I ask a basic question? When you say ROAS of 2.47x, does that mean for every $1 you spent on ads you got $2.47 back in sales? So you are still profitable even after ad spend? I want to make sure I understand before I start putting money into anything.

Also I have a really small budget, like $150 to start. Is that even worth running ads at all or should I focus somewhere else first?

Laura, great questions and do not feel embarrassed for asking — these are exactly the things most new advertisers get wrong because they jump in without understanding the fundamentals.

Yes, your understanding of ROAS is correct. A 2.47x ROAS means $2.47 in revenue for every $1 in ad spend. Whether that is profitable depends on your margins. If your product costs you $40 and sells for $78, your gross margin is roughly 49%. At a 2.47x ROAS on a $600 spend, you generated $1,482 in revenue — but you need to subtract cost of goods, platform fees, shipping, and your original ad spend to get to true profit. ROAS alone does not tell the whole story.

On your $150 budget question — here is my honest professional take: $150 is very thin for Google Search Ads. You will not gather enough data to optimize before it runs out. For that budget, I would suggest:

1. Facebook/Instagram with a tight audience — lower CPC means more data points for your money
2. Pinterest Ads — handmade jewelry performs exceptionally well there and CPCs are often lower than both major platforms
3. Organic first — build Instagram and Pinterest organically for 60-90 days, then use paid to amplify what is already working

$150 in paid ads is a learning budget, not a growth budget. Treat it as tuition, not profit generation.

Yo this thread is gold! Bookmarking immediately.

Rex your retargeting combo idea is exactly what I started doing last month for my dropshipping store and the difference is honestly crazy. Like Facebook alone was just bleeding money but once I set up the Google-to-Facebook retargeting funnel my cost per acquisition dropped almost 40%.

Also @NewbieLaura Chris is right about Pinterest!! Handmade jewelry on Pinterest is like shooting fish in a barrel. My sister does handmade stuff and she gets way more traction there than Instagram for way less effort. The audience is already in buying mode on Pinterest, it is basically a visual search engine at this point.

One thing I would add for tiny budgets — do not sleep on Google Performance Max campaigns. They are automated, they pull from all Google surfaces (search, shopping, YouTube, display), and for small budgets they can be surprisingly efficient once they get enough conversion data. Took about 3 weeks to optimize on mine but now it just runs.

Excellent thread. I want to build on what ConsultantChris said about ROAS versus true profitability because this distinction is critical and I see small business owners get burned by it constantly.

There is a metric called MER (Marketing Efficiency Ratio) that gives a more honest picture of overall advertising health. It is calculated as:

Total Revenue / Total Ad Spend (across ALL channels)

When you look at each channel in isolation, you will almost always over-attribute to whatever channel gets the last click. The customer who converted on Google may have seen your Facebook ad three days earlier. Attribution is messy and most small business dashboards do not capture it accurately.

For practical purposes, I recommend anyone running both platforms to:

• Track a weekly MER number to see overall marketing health
• Use a 7-day click, 1-day view attribution window on Facebook rather than the default
• Set up Google Analytics assisted conversions report to understand which channels assist versus close sales
• Consider a simple post-purchase survey asking customers where they first heard of you — self-reported data is imperfect but adds useful color

EcomKing_Rex, your data is genuinely useful. The one caveat I would raise is that four months is a good test but seasonal factors in outdoor gear (spring gear-up, holiday gifting) can skew platform performance significantly. Would be worth revisiting the same test in Q3 to see if the gap narrows or widens.

DigitalDave_Pro — great catch on the match types. I ran a mix: mostly phrase match with some exact match on my highest-intent keywords. I deliberately avoided broad match after getting burned by it early on when I was running ads for the first time two years ago. Broad match on a small budget is a black hole.

And yes, I used Google Shopping for the product campaigns and Search only for branded and category-level keywords. Shopping definitely pulled the heavier load on the conversion side.

MarketingMaven_Tara — the MER concept is something I had not put a name to but instinctively felt. You are right that looking at channels in isolation creates a false picture. I am going to start tracking that weekly number. And the seasonal point is well taken — I launched the test in November through February which is not exactly peak outdoor season. Would be interesting to rerun this April through July.

Sam glad the retargeting combo is working for you too. 40% drop in CPA is massive. What audience size were you retargeting? I found under 1,000 warm visitors the Facebook algorithm struggles to optimize properly.

Okay I have been lurking on this thread long enough, I have to jump in because this is exactly the conversation I needed this week!

I run a small social media management agency and most of my clients are small e-commerce businesses with budgets between $300-$800/month. The Google vs Facebook question comes up literally every single onboarding call and I always say the same thing: start with where your customer already is in the journey.

If your product solves a specific problem people actively search for — go Google first! If your product is more of an impulse or lifestyle purchase where people do not know they want it yet — go Facebook/Instagram first and build desire before you ask for the sale.

Handmade jewelry (hi Laura!) is actually interesting because it spans both. People do search for gifts, for specific styles, for occasions. But they also impulse buy when they see something beautiful in their feed. So honestly for jewelry I would test both with even $75 each and see which one your specific audience responds to!

Also this whole thread should be pinned. This is exactly the kind of real-world data and strategy talk that is hard to find anywhere that is not trying to sell you a course!

Good data. One thing nobody has mentioned yet — ad fatigue on Facebook is real and it compounds fast on small budgets. Your creative needs rotating every 2-3 weeks minimum or your CPM climbs and your results tank even if the audience and targeting stay identical. Google does not have this problem to the same degree because the trigger is keyword intent, not creative novelty.

Factor creative production time and cost into your actual Facebook budget math. It is never just the ad spend.

Wow thank you everyone, I genuinely did not expect this much help when I posted that question! ConsultantChris and BrandingBee especially — the idea of treating $150 as tuition rather than profit is a really healthy mindset shift for me.

I am going to take the advice and start organic on Pinterest and Instagram for the next two months, build up some content, and then use a small paid budget to boost what is already getting traction. That feels way less overwhelming than jumping straight into ads blind.

Will report back with results. Fingers crossed!

QuietObserver_Mike raises a point that is worth expanding on because it catches a lot of advertisers off guard.

Facebook frequency — the average number of times one person sees your ad — is the metric to watch. Once frequency climbs above 3.0 for a cold audience, performance almost always deteriorates. You start paying the same or more to show your ad to people who have already seen it and ignored it twice. The algorithm keeps spending your budget regardless.

For a small budget advertiser this can happen within days, not weeks. Narrow audiences plus limited creative variety equals high frequency fast. The fix is either broader audiences, more creative variations, or shorter campaign flights with pauses in between.

Good thread Rex. This is the kind of platform-level detail that saves people real money.
