CRO services in Houston typically range from $3,000-$15,000 per month, depending on project scope and company size. Houston rates tend to be 10-15% lower than Austin's tech-focused market while offering comparable expertise, especially for energy, manufacturing, and healthcare clients. Most Houston agencies structure pricing in tiers: analytics audits ($2,500-$5,000), ongoing testing programs ($5,000-$10,000 monthly), or comprehensive optimization campaigns ($10,000-$15,000 monthly). Many Houston agencies also offer performance-based components where fees partially tie to conversion improvements, which is less common in Dallas or San Antonio. When requesting quotes, ask specifically about experience optimizing for Houston's diverse, multinational customer base, as this expertise justifies premium pricing.
