Every GEO Platform Ranked by Domain Authority (April 2026)

There are 19 dedicated Generative Engine Optimization platforms in 2026. We pulled live backlink data on every one of them. Here's the definitive ranking by domain authority — the metric that determines whether AI search engines actually cite your tool when someone asks "what's the best GEO platform?"

5 Things That Stand Out

1. Otterly AI Leads Without Major Funding

Otterly sits at rank 413 with no disclosed venture capital. It built authority the hard way — 10,000+ users, community word-of-mouth, and consistent content. That's 14% higher authority than Profound, which raised $35M in a Series B.

2. AirOps Has the Most Raw Backlinks

At 22,015 backlinks from 2,768 referring domains, AirOps has nearly 2.5x the backlinks of #2 Profound (9,896). Yet it ranks 4th in authority (329 vs Otterly's 413). This suggests domain diversity matters more than raw volume.

3. Two Platforms Have Dangerous Spam Scores

Promptwatch (40%) and Superlines (38%) both have spam scores above 30%. High spam scores can actively hurt AI visibility — LLMs treat sites with spammy link profiles as less trustworthy. If you're evaluating these tools, this is a red flag worth asking about.

4. Goodie AI Is Surprisingly Low

Despite being positioned as a serious Profound competitor (pricing at $495/mo), Goodie AI has a domain authority of just 47 with only 36 backlinks. This suggests the product may be strong, but the web presence is nearly invisible.

5. Three Platforms Start at Zero

Gauge, Visibili, and 99Visibility all have zero or near-zero authority. For Gauge and Visibili, this limits AI search discoverability. For 99Visibility (that's us), we're publishing this study as part of building that authority from scratch — transparently.

What This Means If You're Choosing a GEO Tool

Domain authority isn't everything. A tool with rank 47 might have better features than one at rank 413. But if you're evaluating which GEO platform to trust with your AI visibility strategy, it's worth asking: can this tool be found by the AI systems it claims to optimize for?

FAQ

How often do these rankings change?

Domain authority shifts slowly — it takes months of consistent link building to move meaningfully. We plan to re-run this study quarterly. The next update will be in July 2026.

Why is 99Visibility ranked last?

Because we launched recently and haven't built backlinks yet. We included ourselves to be transparent. This study is one step toward building authority through original research rather than paid links.

What's a good spam score?

Under 10% is healthy. Between 10-30% is worth monitoring. Above 30% is a red flag that suggests low-quality or artificial link building. Two GEO platforms in our study exceed this threshold.
