Facebook Post Checker analyzes text content against Facebook's posting best practices, character limits, and algorithm-friendly patterns. It checks post length (optimal 40-80 characters for engagement, max 63,206), validates link preview compatibility, counts hashtags against the recommended limit (1-3 for Facebook vs 20+ for Instagram), and flags content patterns that reduce organic reach such as engagement bait phrases that Facebook's algorithm actively penalizes.
Social media managers scheduling Facebook content, small business owners managing their own Pages, and marketing agencies handling client social media accounts. The tool runs entirely in your browser — your data never leaves your device.
