Contract Lock-In, Add-On Fees & API Rate Gotchas
Semrush hides its most powerful API capabilities behind custom enterprise quotes, making cost forecasting difficult for mid-market firms. Ahrefs uses a three-month expiration window for PAYG credits, meaning unused API units or crawl credits vanish if not consumed quickly. Both platforms charge significant premiums for additional seats, which can inflate agency overhead by 30% annually if not managed via centralized user governance.
