Reels, Stories and Feed: what each does for b2b companies

Reels — top-funnel awareness. Where cold audiences discover you. For b2b companies, focus on: Thought-leader Reels from the CEO, case-study carousels with named logos, and 'behind the scenes at [event]' Stories. Keep them 9–30 seconds, hook in the first 1.2 seconds, text on-screen for silent viewers, clear verbal CTA.

Stories — retargeting. Pixel-target Reel viewers (50%+ watch), profile visitors and site visitors with social proof, limited offers and DM-sticker prompts. Story CPMs for b2b companies run 20–35% cheaper than Feed in 2026 and almost nobody is optimising them — real arbitrage.

Feed — trust and consideration. For mid-funnel users who clicked a Reel but aren't ready yet. Use editorial-looking carousels: client quotes, numbers, case studies. Feed is where trust gets built between first Reel view and final conversion.

Peak posting windows

Creator partnerships: the 2026 credibility shortcut

A branded-content ad from a mid-tier creator (10k–150k followers in your niche) consistently beats brand-owned creative by 20–50% for b2b companies. Negotiate 30–90 days of whitelisting rights and run the creator post as a dark-post ad from your own ad account.
