A Comprehensive Analysis of Facebook and Google Ads: How to Scientifically Allocate Budgets Across the Two Platforms

In marketing strategies, Facebook and Google are like two different weapons, each with its own strengths; the key lies in how to use them in combination. Many marketers have experienced this: once Facebook ads find suitable creative materials, they can go viral very quickly, with surprisingly impressive initial data. However, this explosive growth is often difficult to sustain. Why do Facebook and Google exhibit such different performance? Vaxelabs will objectively analyze the characteristics of these two platforms to help advertisers better develop their campaign strategies.

User Intent: The Inherent Differences Between Social and Search Scenarios

Facebook users primarily engage in content browsing, social interaction, and entertainment. Google users, on the other hand, tend to search with specific needs. This fundamental difference leads to distinct conversion characteristics between the two platforms. Industry data shows that Google search ads have a relatively high average conversion rate, while Facebook excels in brand exposure and user engagement. From a user psychology perspective, Google ads capture proactive needs; users only search when they have a specific need. Facebook ads, however, stimulate latent needs, reaching users who might be interested in the product through precise audience targeting.

Material fatigue: Different challenges on two major platforms

Facebook does indeed face the challenge of creative fatigue. A high-performing creative may have a limited lifespan, requiring continuous updates and optimization. To address creative fatigue, Facebook advertisers require weekly updates to some ad creatives and the timely removal of ads with declining performance. The first few seconds of video content are crucial, needing to quickly grab the user’s attention. Google Ads also faces ad fatigue, but in a different form. Search ad keyword quality scores fluctuate with click-through rates, and display ads also require regular creative updates. However, unlike Google Ads, search ads rely more on keyword strategy and bid optimization, with relatively lower dependence on creative content.

Data capabilities: Attribution analysis in different ecosystems

Following the update to iOS’s privacy policy, all advertising platforms face challenges in data tracking. While Facebook’s Conversion API offers some solutions, data integrity remains compromised. Google has an advantage in this area, capable of building relatively complete user journey analytics based on user behavior within the Google ecosystem. Google Analytics 4 provides cross-platform data insights to help advertisers better understand the user journey. Notably, both platforms are continuously improving their data analytics and attribution models; Facebook has launched new aggregated event measurement tools, and Google has enhanced its conversion modeling capabilities. Objectively speaking, both are adapting to the new privacy environment and striving to provide more accurate performance evaluations.

Ecosystems: The Different Values ​​of Closed and Open Systems

Google’s advertising ecosystem is indeed more diverse, encompassing search, display, YouTube, Maps, and other products, reaching users across various scenarios. Facebook’s (Meta) ecosystem is equally vast, including platforms like Facebook, Instagram, and WhatsApp, covering multiple aspects from social to commercial. Both ecosystems have their value: Google can capture the entire user journey from need generation to decision-making; Facebook, on the other hand, can effectively deliver brand information and product value within users’ social and entertainment contexts.

Scientific allocation: Budget strategies based on product type and marketing objectives

Based on objective data analysis, we recommend advertisers allocate their budgets according to their business characteristics:
* **Brand Awareness Enhancement:** Facebook and Instagram ads excel at quickly building brand awareness.
* **Potential Demand Discovery:** Facebook’s similar audience and interest targeting effectively reach potential customers.
