Facebook Ads vs Google Ads: Full Comparison 2025

Yes, but you miss the users actively searching for your product. Meta Ads are ideal for creating awareness and remarketing, but they do not capture high-intent searchers. Running Meta Ads without Google Ads means competitors capture your Meta-educated audience at the search stage — a significant revenue leak.

Average Facebook Ads CPM in India ranges from ₹100–400 depending on audience, placement, and industry. Finance and insurance verticals see higher CPMs (₹300–600). Broad consumer audiences on feed placements average ₹150–250. Reels placements are typically 20–40% cheaper than feed. CPMs rise during festive seasons (Diwali, Christmas) by 50–100%.

Apple's App Tracking Transparency (ATT) framework since iOS 14.5 requires users to opt-in to cross-app tracking. Roughly 75% of iOS users opt out, reducing Meta's visibility into off-platform conversions. This affects reporting accuracy (conversions are modelled, not measured), audience targeting quality, and retargeting pool sizes. The impact is greatest for lower-funnel conversion campaigns. Meta's Conversions API (server-side tracking) partially mitigates this.

Meta requires a minimum of $1/day per ad set (approximately ₹80–85/day). However, effective campaigns need sufficient budget to exit the learning phase: at least ₹500–1,000/day per ad set to gather enough data. For meaningful results and learning phase completion, budget ₹15,000–30,000/month minimum per campaign objective.

Google Ads wins for B2B through high-intent search — decision-makers searching for solutions find your ads at the moment of need. Facebook Ads can work for B2B with detailed job title and interest targeting, but LinkedIn Ads is the specialist B2B platform. For most B2B businesses: Google Search Ads first, then LinkedIn Ads, then Meta Ads for retargeting brand-aware prospects.

Set up a unified tracking approach: install Google Tag Manager and configure both Google Ads conversion tags and Meta Pixel through it. Use UTM parameters on all ad URLs to track in Google Analytics 4. For cross-channel attribution, use GA4 data-driven attribution model which distributes conversion credit across touchpoints. For e-commerce, consider a third-party attribution tool like Triple Whale or Northbeam.
