What is Meta Ads? Facebook & Instagram Advertising Guide

Always choose the objective matching your actual goal. For website purchases: Conversions. For leads: Lead Generation or Conversions. For app installs: App Installs. Meta's algorithm optimizes delivery to people most likely to complete your chosen objective — choosing the wrong one defeats this.

Primary metrics: Cost Per Result (cost per lead/purchase), ROAS (for e-commerce), and Cost Per Landing Page View (for traffic). Secondary: Frequency (impressions per person — over 3.5 indicates audience fatigue), CPM trends (rising CPM = audience saturation), and Relevance Score (ad quality indicator).

Meta Advantage+ (formerly Automated Ads) is Meta's AI-powered campaign automation suite. Advantage+ Shopping Campaigns automatically find the best audiences, placements, and creative combinations for e-commerce. It requires minimal manual targeting setup — you provide creative assets and budget, Meta's AI handles everything else. Advantage+ consistently outperforms manually-structured campaigns for e-commerce advertisers with sufficient purchase conversion data.

The learning phase is the period when Meta's delivery system optimizes ad set performance. It requires approximately 50 optimization events per ad set within a 7-day window to exit learning. During learning: costs can be higher and more variable. Avoid editing ad sets during learning (it resets the phase). Best practice: consolidate campaigns into fewer ad sets with higher individual budgets to exit learning faster.

Cold audience targeting options: (1) Interest targeting — target people who follow relevant pages or have interests aligned with your product, (2) Behavioral targeting — online buyers, frequent travelers, business decision-makers, (3) Demographic targeting — age, location, income, education, (4) Lookalike Audiences built from your customer list (most effective), (5) Broad targeting — let Meta's AI find audiences with no demographic restrictions (increasingly effective as Meta's algorithm improves).

Video consistently outperforms static images by 2–3x for conversion campaigns. Hook the viewer in the first 3 seconds; most drop off within 3 seconds if not engaged.
