Google Ads vs Facebook Ads | Which Platform to Start With

The fastest way to lose money online is running ads on the wrong platform. You've got a limited budget, limited time, and zero room for expensive mistakes. Should you start with Google Ads or Facebook Ads?

Here's the uncomfortable truth: most micro-businesses waste their first £300–£500 testing both platforms simultaneously, spreading their budget so thin that neither campaign gets enough data to succeed. Then they conclude "paid ads don't work for us" and give up entirely.

This article forces a different approach: make one informed decision, commit 100% of your budget to a single platform for 90 days, and actually learn what works.

The decision isn't about which platform is "better"—it's about which platform matches how your customers actually buy. Are they actively searching for your solution right now (Google), or do they need to discover it while scrolling through their feed (Facebook)?

By the end of this guide, you'll know exactly which platform deserves your first test budget, why, and what minimum spend you need to get meaningful results.

What You'll Have When Done: A finalized decision on where your first £100–£300 of ad spend will go, with confidence that you've chosen the right platform for your business type. Time Needed: 30 minutes Difficulty: Confident (requires honest assessment of your business model) Prerequisites: - Defined your ideal customer (Know your audience's pain points) - Determined if paid ads are a priority (Budget allocated for testing) - Set up basic tracking (GA4 and conversion tracking are active)

Quick Start: The 3-Question Decision Flow (10 Minutes)

If you need an answer fast, work through these three questions in order. They'll point you to the right platform based on fundamental business realities, not marketing hype.

Before You Start Make sure you've completed these prerequisites: - ☐ Defined Ideal Customer – You know your audience's pain points and demographics - ☐ Decided Paid Ads are necessary – You have budget allocated for testing (previous step) - ☐ Set up Basic Tracking – GA4 and conversion tracking are active on your website Not sure you've properly set up tracking to measure conversion? NetNav's audit checks if your Google Analytics and conversion tags are firing correctly across your key pages in 60 seconds.

Question 1: What's Your Primary Goal?

Demand Capture (Google): Your customers already know they need your solution. They're typing "emergency plumber Manchester" or "divorce solicitor near me" into Google right now. You want to appear when they search.

Demand Generation (Facebook): Your customers don't know they need your solution yet. They're scrolling Instagram and you need to interrupt them with something compelling enough to make them stop and consider your offer.

Your answer: If people are actively searching for what you sell, lean Google. If you need to create awareness first, lean Facebook.

Question 2: The Intent Test

Google Check: Open Google in a private browser window. Type in 3–5 phrases your ideal customer would use when they're ready to buy. Do you see:

•Paid ads at the top?
•3+ competitors bidding on those terms?
•Search volume (use Google Keyword Planner for free estimates)?

If YES to all three: Google Ads is viable. There's existing demand.

If NO: Either the search volume is too low, or your product/service is too new. Facebook is your better starting point.

Question 3: The Creative Reality Check

Google Ads requires:

•Strong text-based ad copy (headlines and descriptions)
•Keyword research to identify what people search for
•Fast-loading landing pages that match search intent

Facebook Ads requires:

•Eye-catching images or video (you can't succeed with boring visuals)
•Detailed audience targeting based on demographics, interests, behaviours
•Scroll-stopping hooks that interrupt the feed

Your answer: Which creative format can you produce consistently? If you're better with words than visuals, Google has a lower creative barrier. If you've got strong product photography or can create simple videos, Facebook rewards visual quality.

Budget Reality Check

Minimum viable test budgets:

•Google Ads: £10–£15/day for 30 days = £300–£450 total
•Facebook Ads: £5–£10/day for 30 days = £150–£300 total

These aren't "recommended" budgets—they're the absolute minimum needed to gather enough data to make informed decisions. Anything less and you're just guessing.

Make Your Commitment

Write this down (seriously, write it):

Platform: [Google Ads / Facebook Ads]

Start Budget: £[X] per day for 30 days

Goal: [Lead / Sale / Awareness]

Validation Checklist You're ready to move forward when: - ☑ You have defined your primary goal (Demand Capture or Demand Generation) - ☑ You have assessed if your product/service is High Intent (Googly) or High Visibility (Feedsy) - ☑ You have calculated the minimum viable test budget required for the chosen platform - ☑ You have committed to the platform you will focus on in the next step Verification Method: You've written down: Platform: [Google/Facebook], Start Budget: [£X], Goal: [Lead/Sale/Awareness]

Complete Step-by-Step Guide: Making Your Final Platform Decision

This section walks through the strategic thinking behind each platform choice, so you understand not just what to do, but why it matters for your specific business model.

Step 1: The Fundamental Difference (Intent vs. Discovery)

The core distinction between Google Ads and Facebook Ads isn't about features or cost—it's about user intent at the moment they see your ad.

Google Ads = Demand Capture

When someone types "emergency plumber Croydon" into Google at 11pm, they have:

•High intent: They need a solution NOW
•Clear problem: A specific issue they can articulate
•Buying mindset: They're comparing options to make a decision

Google Ads (specifically Search Ads) let you appear at this exact moment of high intent. You're not creating demand—you're capturing demand that already exists.

This is why Google Ads work brilliantly for:

•Emergency services (plumbers, locksmiths, electricians)
•Professional services (solicitors, accountants, consultants)
•High-consideration purchases (insurance, mortgages, B2B software)

Facebook Ads = Demand Generation

When someone scrolls Instagram at 11pm, they're:

•Low intent: Not actively looking to buy anything
•Discovery mode: Open to interesting content, not solutions
•Passive mindset: Relaxing, entertaining themselves

Facebook and Instagram Ads interrupt this passive scrolling. You need to create interest where none existed 3 seconds ago. This requires:

•Compelling visuals that stop the scroll
•Hooks that create curiosity or desire
•Offers that feel relevant to their identity

Facebook Ads work brilliantly for:

•Visually appealing products (fashion, home décor, food)
•Lifestyle services (fitness, coaching, courses)
•New or innovative products (nobody searches for what they don't know exists)

The key question: Are your customers actively searching for your solution, or do they need to discover it?

For more context on how search-based advertising fits into your broader marketing strategy, see understanding the difference between SEM and PPC.

Step 2: Targeting Reality Check

How you find your customers differs dramatically between platforms.

Google Ads: Targeting by Keywords (What They Need)

On Google, you target keywords—the actual phrases people type into the search box. Your targeting options are:

•Search terms: "emergency plumber", "best accountant for small business"
•Location: City, postcode radius, or nationwide
•Device: Mobile, desktop, tablet
•Time of day: When your business can actually respond

This requires preliminary keyword research before you launch. You need to know:

•What phrases your customers actually use (not what you think they use)
•Which keywords have commercial intent (buying signals)
•What the competition level looks like (high competition = higher costs)

The advantage: You're reaching people who've self-identified their problem. They've literally told Google what they need.

The limitation: If nobody searches for your solution, Google Ads won't work. Period.

Facebook Ads: Targeting by Demographics (Who They Are)

On Facebook and Instagram, you target people—based on who they are, not what they're searching for. Your targeting options include:

•Demographics: Age, gender, location, language, education, job title
•Interests: Pages they like, content they engage with, hobbies
•Behaviours: Purchase behaviour, device usage, travel patterns
•Custom Audiences: Your existing customers, website visitors, email list

This requires a detailed understanding of your Ideal Customer Profile. You need to know:

•Who your best customers are (demographics)
•What they care about (interests and values)
•Where they spend time online (Instagram vs Facebook)

The advantage: You can reach people who fit your customer profile even if they've never heard of you.

The limitation: You're interrupting them. Your ad needs to be compelling enough to overcome their natural resistance to advertising.

Step 3: Creative & Logistics Requirements

The content you need to create differs significantly.

Google Search Ads: Text-Based

Google Search Ads are primarily text:

•Headlines: 3 headlines, up to 30 characters each
•Descriptions: 2 descriptions, up to 90 characters each
•Extensions: Phone numbers, site links, callouts

You need to be good at:

•Writing effective Call-to-Actions (CTAs) that drive clicks
•Matching your ad copy to search intent (what they typed)
•Creating landing pages that continue the message from the ad

The creative barrier is lower. If you can write clear, benefit-focused copy, you can create effective Google Ads. No design skills required.

Facebook/Instagram Ads: Visual-First

Facebook and Instagram Ads are dominated by visuals:

•Images: High-quality product photos, lifestyle imagery, graphics
•Video: Short-form video (15–30 seconds) performs best
•Copy: Headlines and body text support the visual, but the image does the heavy lifting

You need:

•Professional-looking product photography or stock images
•The ability to create simple videos (even smartphone videos work if done well)
•Design skills or tools (Canva is sufficient for most micro-businesses)

The creative barrier is higher. Boring visuals = invisible ads. You're competing with professional content creators, influencers, and friends' holiday photos for attention.

Before you send expensive traffic anywhere, remember that paid ads rely heavily on site health and speed. NetNav can audit your core landing pages and identify speed bottlenecks or missing trust signals—factors that directly impact your ad conversion rate.

Step 4: Budget & Conversion Readiness

Both platforms require more than just ad spend—you need infrastructure to convert that traffic.

Landing Page Requirements

Sending ad traffic to your homepage is a waste of money. You need dedicated landing pages that:

•Match the promise in your ad (message consistency)
•Have one clear call-to-action (book, buy, enquire)
•Load fast (under 3 seconds on mobile)
•Build trust (testimonials, guarantees, clear contact info)

If you don't have landing pages yet, see create dedicated landing pages without hiring a developer.

Cost Per Lead Reality

Before you spend a penny, you need to calculate your required return on investment. Work backwards:

What's your average customer worth? (Lifetime value, not just first purchase)
What percentage of leads convert to customers? (Your close rate)
What can you afford to pay per lead? (Customer value × close rate = max cost per lead)

Example:

•Average customer value: £500
•Close rate: 20% (1 in 5 leads becomes a customer)
•Max cost per lead: £500 × 20% = £100

If Google Ads in your industry typically costs £50 per lead, you're profitable. If it costs £150 per lead, you'll lose money on every customer.

This calculation must happen before you launch. Otherwise, you're gambling, not marketing.

Step 5: The Final Decision Matrix

Apply these four factors to your specific business:

Choose Google Ads if:

•✅ People actively search for your solution (verified with keyword research)
•✅ You offer emergency, professional, or high-consideration services
•✅ You're better at writing than visual design
•✅ You can afford £10–£15/day for 30 days minimum

Choose Facebook Ads if:

•✅ Your product/service is new, innovative, or visually appealing
•✅ You have strong product photography or can create simple videos
•✅ You know your ideal customer's demographics and interests in detail
•✅ You can afford £5–£10/day for 30 days minimum

Still genuinely torn? Default to Google if you're a service business, Facebook if you're a product business. Then commit for 90 days before reconsidering.

Final Validation You're ready to launch when: - ☑ You have defined your primary goal (Demand Capture or Demand Generation) - ☑ You have assessed if your product/service is High Intent (Googly) or High Visibility (Feedsy) - ☑ You have calculated the minimum viable test budget required for the chosen platform - ☑ You have committed to the platform you will focus on in the next step Verification Method: You've written down: Platform: [Google/Facebook], Start Budget: [£X], Goal: [Lead/Sale/Awareness]

Troubleshooting: Overcoming Decision Paralysis

Common Problems & Fixes Problem: "I feel like I need to be on both platforms." Fix: No, you don't. Splitting a £300 budget across two platforms guarantees you'll fail on both. You need concentrated spend to gather meaningful data. Commit 100% of your limited budget to one platform for the first 90 days. Once you've mastered one channel and it's profitable, then consider expanding.

Problem: "I sell a completely new product/service—nobody searches for it."

Fix: Focus entirely on Facebook/Instagram (Demand Generation). Google Ads requires existing search volume. If your product is genuinely innovative, you need to create awareness first. Facebook's interest-based targeting lets you reach people who fit your customer profile even if they don't know your solution exists yet.

Problem: "I don't know what my Cost Per Lead should be."

Fix: Use the calculation in Step 4 to work backward from your profit margin. If the required CPA is unrealistic for paid traffic in your industry (ask in business forums or Facebook groups for benchmarks), you have two options:

Increase your prices to create more margin for customer acquisition
Wait on paid ads and focus on organic channels until you've validated your offer and pricing

Don't guess. Math doesn't lie.
