merge_type The Power of Using Both Platforms Together

The most successful advertisers do not choose one platform over the other — they use both strategically. Here is an effective cross-platform framework:

1

Awareness: Meta Ads

Use Meta's visual formats to introduce your brand to cold audiences. Reels, Stories and carousel ads build awareness at a low CPM. Target broad interests and lookalike audiences.

2

Consideration: Google Ads + Meta Retargeting

As users start searching for your product category, capture them with Google Search and Shopping ads. Simultaneously, retarget website visitors on Meta with product-specific ads to stay top-of-mind.

3

Conversion: Both Platforms

Google captures high-intent searches while Meta's dynamic retargeting shows users the exact products they viewed. Both platforms work together to close the sale.

4

Retention: Meta Ads + Email

Use Meta's custom audiences to reach existing customers with new products, upsells and loyalty offers. Combine with email marketing for maximum retention impact.

quiz Frequently Asked Questions

If people actively search for your product/service, start with Google Ads to capture existing demand. If your product is visually appealing and impulse-driven, start with Meta Ads. If budget allows, test both simultaneously with a 50/50 split for 30 days.
For meaningful data, each platform needs enough budget to generate at least 30 conversions per month. Calculate: 30 conversions x expected CPA = minimum monthly budget per platform. Starting with $1,000-$2,000/month per platform is a good baseline for most e-commerce businesses.
Google Search ROAS tends to be higher because users have explicit purchase intent. Meta ROAS reflects demand creation — it introduces your product to new audiences who were not actively searching. Both contribute to overall business growth in different ways.
While you can reuse some assets, platform-specific creative performs better. Google Search is text-based, while Meta is visual. For Shopping vs Meta product ads, the same product images work, but the surrounding copy and format should be adapted to each platform's best practices.
TikTok is a strong third platform, especially for products targeting 18-34 demographics. Add TikTok once you have Google and Meta optimized and profitable. Typically allocate 15-20% of your total ad budget to TikTok for testing. See our TikTok Ads Guide.
