Facebook Ads vs Google Ads: Which Platform Wins for Your Business?

You have an advertising budget. You want leads, sales, or both. Two platforms dominate the paid advertising world: Google Ads and Facebook Ads (now officially Meta Ads, but everyone still calls them Facebook Ads). Each one wants your money. But which one will actually give you a return?

Having managed ad campaigns across both platforms at TML Agency, we can tell you this: the platform that works best depends on your business model, your audience, and what you sell. Let us break it down with actual data and real talk.

The Core Difference: Intent vs Interest

This is the single most important concept in this entire article, so read it twice.

Google Ads captures existing intent. Someone searches "buy running shoes online." They want running shoes. Right now. Your Google ad appears, they click, they buy. You intercepted someone who was already on their way to purchase.

Facebook Ads creates interest. Someone is scrolling through their feed, looking at memes and vacation photos. Your ad for running shoes appears. They were not looking for shoes, but your creative caught their eye. Now they are interested. Maybe they click, maybe they save the post, maybe they buy next week after seeing your retargeting ad.

Intent vs interest. Demand capture vs demand generation. This fundamental difference shapes everything — costs, conversion rates, creative strategy, and ROI timelines.

Cost Comparison: CPC and CPM Benchmarks

Let us talk money, because that is what you actually care about.

At first glance, Facebook looks way cheaper. And per click, it is. But do not let the low CPC fool you. Google's higher CPC comes with higher intent, which means higher conversion rates. A Rs 50 Google click that converts at 5% is more valuable than a Rs 10 Facebook click that converts at 1%.

Let us do the math for 1,000 clicks:

• Google Ads: 1,000 clicks x Rs 50 = Rs 50,000 spend. At 5% conversion = 50 leads. Cost per lead: Rs 1,000.
• Facebook Ads: 1,000 clicks x Rs 10 = Rs 10,000 spend. At 1.5% conversion = 15 leads. Cost per lead: Rs 667.

Interesting — Facebook still comes out cheaper per lead in this example. But here is the catch: those 50 Google leads are typically higher quality. They were actively searching for your service. The 15 Facebook leads were casually browsing. The close rate on Google leads is often 2-3x higher than Facebook leads.

So the real comparison is cost per customer, not cost per lead. And that calculation varies wildly by industry.

Targeting: Different Philosophies

Google Ads Targeting

Google targeting is primarily keyword-based. You choose what searches trigger your ads. This means:

• Search intent targeting: Show ads to people searching specific phrases
• Location targeting: Country, state, city, or radius around an address
• Device targeting: Mobile, desktop, tablet
• Demographic targeting: Age, gender, household income (limited)
• Audience targeting: In-market audiences, affinity audiences, remarketing lists
• Time-of-day targeting: Schedule ads for business hours or peak conversion times

The strength: you reach people at the moment they express intent. The weakness: you are limited to people who are actively searching. If nobody searches for your product, Google Search Ads will not help.

Facebook Ads Targeting

Facebook targeting is behavior and interest-based. The platform knows an absurd amount about its users:

• Demographics: Age, gender, education, job title, relationship status, life events
• Interests: Based on pages liked, content engaged with, groups joined
• Behaviors: Purchase behavior, device usage, travel patterns
• Custom audiences: Upload your customer list and target them directly
• Lookalike audiences: Find new people who look like your best customers
• Retargeting: Target people who visited your website, engaged with your content, or watched your videos

The strength: you can reach incredibly specific audiences even if they have never heard of you. "Women aged 25-35 in Chandigarh who are interested in organic skincare and have a household income above Rs 10 lakh" — Facebook can find them. The weakness: these people were not looking for you. You are interrupting their scroll.

Creative Formats: What Works Where

Google Search Ads are text-based. Headlines, descriptions, sitelinks. There is no visual element (unless you run Shopping Ads or Display Ads). Your copywriting has to do all the heavy lifting.

Facebook Ads are visual-first. You have:

• Single image ads
• Carousel ads (multiple images/videos in one ad)
• Video ads (short-form performs best)
• Stories ads (vertical, full-screen)
• Reels ads (15-30 second vertical videos)
• Collection ads (product catalog browsing)
• Lead form ads (collect info without leaving Facebook)

If your product is visually appealing, Facebook gives you more tools to showcase it. A beautifully shot video of your product in use will always outperform a text-only Google ad for impulse purchases. But for high-intent services like "emergency plumber" or "lawyer for property dispute," nobody needs a pretty video. They need to find you fast, which is Google's domain.

Which Industries Win on Google Ads?

Which Industries Win on Facebook Ads?

Retargeting: Both Platforms Excel

Here is a truth about digital advertising: most people do not convert on the first interaction. Studies show it takes 7-13 touchpoints before someone makes a purchase decision. This is where retargeting becomes essential.

Google retargeting (through the Display Network and YouTube) lets you show banner ads and video ads to people who visited your website. It is effective but the display network can feel "spammy" — those ads that follow you around the internet after you looked at a product once.

Facebook retargeting is more sophisticated and less intrusive. Because ads appear in the news feed (where people already spend time), retargeting ads feel like natural content. You can retarget based on:

• Website visitors (specific pages, time on site)
• Video viewers (people who watched 25%, 50%, 75%, or 95% of your video)
• Instagram/Facebook engagers
• People who opened a lead form but did not submit
• Previous customers (for upselling)

The winning strategy most businesses miss: use Google Ads to capture high-intent traffic, then use Facebook retargeting to stay in front of people who did not convert. This combination typically produces the best ROI we see across all our clients.

The Attribution Problem

Here is something nobody talks about enough: tracking is broken.

Apple's iOS 14.5 update gave users the option to opt out of tracking, and roughly 80% did. This means Facebook can no longer track conversions as accurately as before. Your Facebook Ads dashboard might show 10 conversions, but the real number could be 15 or 20. Conversely, it might inflate numbers in some cases.

Google Ads tracking is also imperfect but generally more reliable because conversions happen closer to the click. Someone clicks your ad, lands on your site, fills out a form — Google tracks that entire journey on your website.

Facebook conversions often involve a longer journey: see ad, visit website, leave, see retargeting ad, come back, convert. With tracking limitations, Facebook loses sight of people in the middle of that journey.

This does not mean Facebook is ineffective. It means you need to look at overall business metrics (total leads, total revenue) rather than relying solely on platform-reported numbers.

Budget Allocation: Our Recommended Framework

If you have Rs 50,000 per month for paid advertising, here is how we would typically allocate it:

Service business (B2B): 70% Google Ads, 30% Facebook (retargeting + brand awareness)

E-commerce (D2C): 40% Google Ads (Shopping + Search), 60% Facebook/Instagram Ads

Local business: 60% Google Ads (Local Search + Maps), 40% Facebook (local targeting + offers)

SaaS/Tech: 80% Google Ads (Search), 20% Facebook (retargeting only)

New brand launch: 30% Google Ads (brand + competitor terms), 70% Facebook (awareness + engagement)

These are starting points. After 30 days of data, you adjust based on what is actually converting. The beauty of paid advertising is that everything is measurable. Follow the data, not the theory.

The Combination Strategy That Works

The best advertisers do not choose one platform. They use both in a coordinated strategy:

1. Facebook awareness campaigns introduce your brand to cold audiences. Video content works best here. You are not trying to sell — you are trying to get noticed.
2. Google Search Ads capture the people who see your Facebook ad and then Google your brand or service. Your brand awareness campaign fuels your search campaign.
3. Facebook retargeting re-engages website visitors who came from Google but did not convert. Now they see your ad in their feed with a testimonial or special offer.
4. Google remarketing catches people across the web with display ads, reinforcing your presence.

This funnel approach typically reduces cost per acquisition by 30-50% compared to running either platform in isolation. It is more work to manage, but the results justify the effort.

Common Mistakes on Each Platform

Google Ads Mistakes

• Using broad match keywords without proper negatives (you will bleed money on irrelevant searches)
• Not using ad extensions (sitelinks, callouts, structured snippets are free real estate)
• Sending all traffic to the homepage instead of dedicated landing pages
• Not tracking conversions properly (you cannot optimize what you do not measure)
• Setting and forgetting campaigns (Google Ads needs weekly optimization)

Facebook Ads Mistakes

• Targeting too narrow (let Facebook's algorithm find your audience with broad targeting)
• Using stock photos instead of authentic content (people scroll past generic imagery)
• Not testing multiple creatives (run at least 3-5 ad variations per ad set)
• Giving up after 3 days because you did not see sales (Facebook needs 3-7 days to optimize)
• Ignoring the learning phase (do not change budgets or targeting during the first 50 conversions)

Our Honest Verdict

If you can only pick one platform and you sell services (especially B2B), go with Google Ads. The intent-based targeting means every click has a higher chance of becoming a customer.

If you sell physical products, especially visually appealing ones, Facebook and Instagram Ads will likely give you a better return per rupee spent.

If your budget allows both, use them together. The combination is more powerful than either alone.

At TML Agency, we manage both Google and Meta ad accounts for our clients. We have seen businesses burn through lakhs on the wrong platform, and we have seen Rs 10,000 budgets generate 10x returns on the right one. The difference is strategy, not just spending.
