Google Ads vs Facebook Ads: Which One Should You Choose?
In the era of robust digital marketing, Google Ads and Facebook Ads are dominating the market and are the top choices for Vietnamese businesses. However, many people wonder: Should you choose Google Ads or Facebook Ads to run the most effective advertising?
The article below from MIMA TRADING AND SERVICE CO., LTD will help you make a comprehensive comparison between the two platforms – from how they work, target audience, costs, goals to the level of effectiveness – to make the most appropriate decision for each type of business.
Overview of Google Ads and Facebook Ads
What is Google Ads?
Google Ads is Google's search and display advertising platform – the world's largest search engine. When a user searches for a keyword, your ad will appear at the top or bottom of the search results.
In addition, Google Ads also has the following formats:
- Search Ads: Ads that appear when users search
- Display Ads: Banners on partner websites
- YouTube Ads: Video ads that run before, during or after YouTube videos
- Google Shopping Ads: For e-commerce
What is Facebook Ads?
Facebook Ads is an advertising system that appears on the Facebook platform and linked applications (Instagram, Messenger, Audience Network). Facebook Ads does not rely on keyword searches, but on behavior, interests, and demographics to distribute content.
Popular types of ads:
- Advertising posts (image/video)
- Story Ads
- Reels Ads
- Collection & Carousel Ads
- Lead Ads (collect customer information)
Google Ads vs Facebook Ads – Detailed Comparison of Each Element
Usage Goals
| Element | Google Ads | Facebook Ads |
| Goal | Meeting specific search needs | Creating demand, brand recognition |
| Funnel Stage | Middle and bottom of funnel | Top and middle of funnel |
| Suitable for | People with clear needs | Potential customers who are not aware of the product |
👉 In summary: Google Ads targets people who are searching for products/services, while Facebook Ads reaches people who may be interested but have not searched.
Target Audience
- Google Ads: Based on keywords, location, device, time.
- Facebook Ads: Based on behavior, interests, age, gender, job, education level...
🧠 If you want to target deeply on psychology and interests, Facebook is the strength.
🔎 If you want to target direct needs, Google is a better choice.
Cost and Conversion Rate (ROI)
| Criteria | Google Ads | Facebook Ads |
| Average CPC (VN) | 1,000 – 15,000 VND | 300 – 2,000 VND |
| Conversion rate | High if targeted correctly | Good if the content is attractive |
| Starting cost | From 100,000 VND/day | From 50,000 VND/day |
💰 Facebook is cheaper but needs compelling content to attract the right customers
💳 Google is more expensive but has a high conversion rate, because users are actively searching for products.
Display Speed and Short-Term Effectiveness
- Google Ads: Appears immediately when users search for keywords → immediate impact
- Facebook Ads: Needs time to "warm up" (optimize algorithms, machine learning) → usually effective after 3–5 days of trial run
🎯 If you need to close orders quickly – Google Ads is the preferred choice
🚀 If you need to nurture a long-term customer base – Facebook Ads is a strategic choice
Remarketing Ability
Both Google and Facebook support remarketing – but the implementation is different:
- Google Remarketing: Displays banners on newspapers, YouTube, apps... after the customer has visited the website
- Facebook Remarketing: Re-displays ads when customers have viewed the fanpage, video, inbox, viewed products…
💡 Remarketing on Facebook usually has a better conversion rate, because the displayed content is more vivid and diverse.
Should You Choose Google Ads or Facebook Ads For Your Business?
Choose Google Ads When:
- Selling products/services that users often actively search for (repair services, courses, travel...)
- Want to push orders quickly, to the right hot audience
- The website has been optimized for conversion
📌 For example:
- IELTS center → Google Ads keyword “fast track IELTS course”
- Pest control service → keyword “termite control company HCMC”
Choose Facebook Ads When:
- You want to increase brand awareness
- Products need beautiful images, attractive videos
- The goal is to create demand, not close orders immediately
📌 For example:
- Fashion, cosmetics, functional foods
- Soft skills training, personal coaching
Combining Both Google Ads and Facebook Ads – The Most Effective Formula
💡 Big brands often combine both platforms to optimize:
| Funnel Stage | Platform | Goal |
| Awareness | Facebook Ads | Broad reach – Make an impression |
| Consideration | Facebook Remarketing | Video testimonial, incentives |
| Decision | Google Ads | Close orders from searchers |
🎯 This is a comprehensive strategy, helping businesses not miss any potential customers.
Some Successful Case Studies When Combining Both Platforms
🌟 Case 1: Foreign language learning center
- Facebook Ads → Attract students through reel reviews + shared content
- Google Ads → Promote the keyword "fast track IELTS preparation"
Result: Tripled the number of registrations compared to using only 1 channel
🌟 Case 2: Cosmetics shop
- Facebook Ads → Run minigames, reels first – increase interaction
- Google Ads → Remarketing abandoned carts
Result: Increased conversion rate by 27%, cost/customer reduced by 40%
