What to look for in a SaaS SEO agency

• Can they show experience with product-led SEO, comparison pages, alternative pages, and use-case pages?
• Do they understand topic clustering, search intent, and bottom-of-funnel content?
• How do they measure success: traffic, conversions, assisted revenue, or pipeline?
