Startups in the U.S. typically invest $500–$2,500/month for foundational SEO services like on-page optimization, basic keyword research, and limited content. This is a reasonable starting range. For more comprehensive SEO (regular content, link building, technical fixes), budgets usually fall between $2,500–$5,000/month. Depending on competition, niche, or a funded growth strategy (e.g., for software or tech startups), spending can range from $2,500–$7,500/month
