AI SEO Agencies for Mid-Market Clients (September 2026)

AI SEO here means being named in assistant answers, and NOVOS puts a number on it. Its Osprey program, built on SEO, digital PR and site architecture, reports share of AI answers up 21.4 points in twelve months to 72.6%, with Osprey first in six of nine tracked topics; the Heal's campaign landed 23 pieces of coverage and 20 links from 18 domains onto sofa category pages, with AI visibility reported as rising and no figure given. Wolfgang Digital's AI Search Optimisation add-on lists audits, bot-traffic analysis and fact-checking but publishes no outcome; its documented AI work is in paid search and email, such as Producthero rewriting 1,471 Shopping titles for Very Ireland in a controlled test that ran 11% higher CTR by month four. Klingit sits on this page by tag rather than by evidence: its documented work is generative campaign production, an AI-generated launch video for LOOP and a Halloween campaign for Häxan built instead of a photoshoot, which the curator describes as production, not engineering.

The sorting question for a mid-market brand is how the answer share is measured. Ask which assistants, prompt set and tracking tool sit behind any share-of-answer figure before comparing agencies, and what the retainer is priced against: NOVOS scores retainers on its own 20-point Signal framework, so agree revenue or answer-share targets you can verify independently. The documented cases here are consumer brands; a B2B company should ask for the equivalent numbers in its own category.
