Instagram

Both are essential for most consumer brands, but they serve different goals. Instagram is better for: e-commerce (Instagram Shopping and shoppable posts drive direct purchases), established brand storytelling (high-production visual content), influencer marketing with measurable ROI, and reaching 25-45 year olds with purchasing power. Instagram's ad platform (through Meta Ads Manager) offers superior targeting and measurement. TikTok is better for: organic discovery and virality (the FYP gives any content a chance), reaching 18-25 year olds, trend-driven marketing, and building brand personality through entertainment. TikTok's ad platform is growing but less mature than Meta's. Most consumer brands run both — TikTok for organic reach and cultural relevance, Instagram for conversion and paid media.

Instagram's feed is algorithmically ranked by default, not strictly chronological. The algorithm prioritizes content based on: your relationship with the account (do you often interact?), post recency (newer posts rank higher), your interest signals (have you engaged with similar content?), and usage context (are you on mobile or desktop, browsing quickly or slowly?). Instagram introduced a 'Following' feed option in 2022 that shows only posts from accounts you follow in reverse chronological order — accessible by tapping the Instagram logo and switching feeds. Stories appear in algorithmic order (most relevant accounts first, not chronological). Reels are primarily algorithmic discovery. For businesses, this means posting consistently and encouraging engagement (saves, shares, comments) signals the algorithm to show your content to more followers.

Instagram generates revenue almost entirely through advertising — it's estimated to contribute $30-50+ billion annually to Meta's total revenue (Meta doesn't break out Instagram separately). Instagram's ad formats include: Feed ads (photo and video between organic posts), Stories ads (full-screen between user Stories), Reels ads (between Reels videos), Explore ads, and Shopping ads (product discovery in the Shop tab). Advertisers pay per click (CPC) or per thousand impressions (CPM) — typical Instagram CPMs range from $5–15 for broad audiences to $30–50+ for narrow, high-intent audiences. Meta's competitive advantage is cross-platform data: an Instagram ad can be targeted to people who visited your website on desktop, engaged with your Facebook page, or match your customer list email addresses. This makes Instagram advertising highly efficient for direct-response campaigns.
