How large is the AI search visibility market?

This research did not locate a sufficiently transparent US-only revenue series to publish a national market-size estimate with confidence. The strongest directly relevant public sizing page found was a global commercial forecast.

The publisher’s scope includes visibility tracking, content optimisation, schema/entity work, analytics and consulting or managed services. Its public page does not provide enough underlying interview, revenue-allocation or deduplication detail to reproduce the total. Confidence: low to moderate as a directional global forecast; insufficient for US budgeting or supplier market-share calculations. (marketsandmarkets.com)

Should the desk retain its earlier US estimate?

Not as a public market fact. The supplied desk notes’ $350 million–$1 billion US spending range for 2026 was explicitly a planning hypothesis. This research has not independently substantiated its buyer counts, average expenditure or allocation of existing SEO and PR budgets.

Do not apply an assumed US share to the global forecast, or add software revenue to agency billings without adjusting for bundled licences and subcontracting. A useful next market-sizing exercise would reconcile:

• US-billed specialist software revenue;
• separately contracted AI-visibility services;
• explicitly allocated AI work inside existing retainers;
• software passed through by agencies;
• duplicate purchasing across business units and platforms.

Until those inputs exist, “US expenditure not established” is more defensible than a precise-looking total.
