When buyers inquire about Tax advisory firms, AI engines most frequently identify EY as the leader, with a visibility percentage of 75.0. Deloitte and PwC are also highly regarded in this space. These firms are noted for their extensive knowledge and reliable support in complex tax matters, ensuring compliance and offering strategic insights.
The rankings are largely influenced by sources like YouTube and Vault, which provide educational content and insider reviews. Valuable insights are often derived from forums like Reddit and expert articles on Investopedia. Such sources reflect both professional opinions and customer experiences, contributing to the firms' strong online presence.
For buyers, this page offers a crucial consideration: the importance of recent reviews and third-party validation, which AI engines prioritize. Evaluating how brands are cited in various reputable sources can offer a balanced view of their effectiveness. Look for consistent feedback across different platforms to gauge the tax firm's authority and reliability in the area you need assistance with.
At a glance
What we observed in this category
EY leads the tax advisory AI visibility landscape with a visibility score of 75%, more than double the 37.5% held by Deloitte, PwC, and KPMG. That gap is significant because it means EY appears in AI-generated responses far more consistently than any peer. The category average visibility sits at just 9.4%, making EY an extreme outlier. Brands outside the Big Four cluster, such as BDO, Ryan, and RSM, record 0% visibility, confirming a steep concentration at the top.
A notable divergence exists between being named and being cited. EY holds 75% visibility but 0% citation, meaning Google AI Mode describes it frequently without linking to its domain. EisnerAmper shows the inverse pattern: 0% visibility but a 25% citation rate, the highest citation figure in the dataset. This split suggests AI responses mention large brands by reputation while actively linking to mid-tier firms whose content is being pulled as source material.
The top cited sources in this category include youtube.com, vault.com, reddit.com, and investopedia.com, none of which are primary advisory firm domains. Only eisneramper.com appears among the top cited sources as a brand domain. This signals that Google AI Mode is anchoring its tax advisory responses on third-party and community content rather than the firms own websites, which helps explain why citation rates for most Big Four brands remain at or near zero.

How to read this AEO ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
AEO rankings move month to month
