Search visibility for SaaS companies is undergoing a fundamental shift. Traditional keyword rankings still matter, but they are no longer the only way software buyers discover new products. AI-powered search engines, large language models, and generative answers increasingly influence how decision-makers research, compare, and shortlist SaaS solutions.
As a result, SaaS companies are rethinking what they expect from SEO partners. Instead of generic optimization tactics, they are looking for agencies that understand B2B software growth and know how to position brands for visibility across both classic search results and AI-driven discovery.
Below is a roundup of SaaS SEO agencies that stand out for helping software companies adapt to an AI first search landscape.
1. MADX Digital
MADX Digital is a SaaS-focused SEO agency known for aligning organic growth with real business outcomes. Rather than treating SEO as a traffic-only channel, MADX builds strategies around the full SaaS buyer journey, from early problem awareness through to product evaluation and conversion.
A key differentiator is its focus on Generative Engine Optimization. MADX helps SaaS brands improve their visibility not only in traditional search results, but also in AI-generated summaries, comparisons, and recommendations. This includes strengthening topical authority, improving information structure, and reinforcing brand signals across the web.
For SaaS companies operating in competitive categories, MADX positions SEO as a long-term growth engine designed for both human buyers and AI-driven discovery.
2. Grow and Convert
