GEO Snapshot vs MozBar: Domain Authority vs AI Readiness

MozBar and GEO Snapshot answer different questions about the same page, one about authority, one about access.

Why MozBar still matters after fifteen years

MozBar is built around Moz's Domain Authority and Page Authority scores, an estimate of how likely a page or domain is to rank well based on its link profile, and it has stayed a fixture in SEO toolkits since it first shipped. The guest tier, no account needed, covers on page elements, general attributes and internal link detail. A free Moz account unlocks DA and PA, and Moz Pro subscribers get Spam Score, page optimisation and keyword ranking queries on top. Version five added schema markup identification, hreflang and robots.txt checks, and sitemap discovery, so the toolbar has moved some way toward technical auditing beyond authority scores alone.

Domain Authority measures links, not GEO readiness

DA and PA are link based metrics built for one purpose, estimating traditional search ranking potential. They say nothing about whether a page's content can be read and lifted by a generative answer. MozBar's robots.txt and sitemap checks confirm the files exist, but they do not parse robots.txt by AI crawler group, so a page can pass MozBar's check while still being invisible to the specific bot that fetches a page at the moment it might be cited in an AI answer.

Everything MozBar leaves unchecked

GEO Snapshot compares a page's served HTML against its rendered version, the check that catches JavaScript built content that looks complete to a person and is empty to a crawler. It groups robots.txt results by AI product rather than treating access as a single pass or fail, and validates schema against the required properties for its actual type rather than just confirming markup is present. All of it free, with no account tier to unlock further checks.

What a Moz Pro subscription buys you

GEO Snapshot has no paid tier at any point, all twenty eight checks, no account. MozBar's guest tier is free with no login. A free Moz account adds Domain Authority and Page Authority scores. Beyond that, Moz Pro subscriptions, which unlock Spam Score, keyword tracking and page optimisation recommendations, start at around 49 dollars a month for the entry Starter plan as of 2026, rising through Standard, Medium and Premium tiers for agencies tracking more keywords and running multi site campaigns.

Pick a lane, or run both

Most teams end up running both rather than choosing.

Agency reporting Domain Authority to clients. Keep MozBar and the underlying Moz Pro subscription, DA remains a widely recognised shorthand in client conversations even though it is Moz's own metric rather than a Google signal. Add GEO Snapshot to answer the AI visibility question that is increasingly part of the same client conversation.

Single site owner with no SEO budget. GEO Snapshot first, it needs no account or subscription for any of its checks. MozBar's free guest tier is worth adding for a quick look at on page basics, but DA and PA specifically require signing up for something.

In house marketing team already on Moz Pro. Keep the subscription for keyword tracking and reporting, run GEO Snapshot alongside it for AI crawler access. Neither check overlaps with what the other does.

MozBar and GEO Snapshot, compared properly

Before you install either, some answers

Does MozBar check AI crawler access? No. Its robots.txt and sitemap checks confirm the files are present, not whether specific AI crawlers are allowed or blocked.

Do I need a Moz account to use MozBar? No for the guest tier. A free account adds DA and PA, a paid Moz Pro subscription adds further metrics starting at around 49 dollars a month.

Is Domain Authority relevant to AI search visibility? Not directly. DA estimates ranking likelihood in traditional search based on links. It says nothing about whether a page's content is readable by an AI crawler.

How much does Moz Pro cost? Plans run from around 49 dollars a month for Starter up through Standard, Medium and Premium tiers, scaling with keyword tracking volume and number of sites.

Can GEO Snapshot replace MozBar? No, they measure different things. GEO Snapshot has no link authority metric at all.

Which is faster for a quick check? Both run in one click. MozBar for authority at a glance, GEO Snapshot for the full AI readiness picture.

Should an agency drop Moz Pro for GEO Snapshot? No. Clients still ask about Domain Authority by name, so it stays useful as a reporting metric. GEO Snapshot covers a genuinely different question and sits alongside it rather than replacing it.
