Is Moz data accurate, or are you acting on a stale snapshot?
Honest answer: partly. Moz reads what is on your page, but its headline metrics like Domain Authority and its link index are built from a crawl it ran earlier on its own schedule, so what you see is a snapshot that can lag the live web. On Trustpilot and G2, reviewers report that the index keeps showing pages that were deleted long ago, as if the crawler had never revisited the site, and that a score can sit unchanged for years even after the site behind it was overhauled (Trustpilot, G2). Read fairly, that is a structural trait of every tool that pre-crawls and caches, not a scandal. Here is what it means for your decisions, and where reading the live page changes the math.
What Moz users report about the data
We cannot verify individual accounts, so read these as what reviewers on public review sites describe, not as our findings. Across Trustpilot and G2, the pattern is about freshness and transparency, not about Moz being wrong on purpose (Trustpilot, G2):
- Data that does not refresh often enough. Reviewers report that the underlying data sources feel outdated and do not update frequently enough to draw timely conclusions from.
- An index that remembers deleted pages. Reviewers report the crawl still showing URLs that were removed long ago, and corrections that do not seem to take.
- Scores that sit still, with numbers you cannot trace. Reviewers report Domain Authority confusion and a lack of transparency around where the data comes from, which leaves a non-expert unable to act on the number.
Why any pre-crawl tool shows you a snapshot
Here is the part the angry reviews leave out, in fairness to Moz. Every large SEO tool works the same way at the core. It crawls the web on its own schedule, stores what it finds, and computes metrics from that stored copy. Domain Authority, link counts, and the page index are all built from that periodic crawl. That design is what lets a tool answer a question about a site it was never pointed at, and it is genuinely useful. The trade-off is baked in. The day you look, you are seeing the last time the crawler visited, not the live web. If it re-crawled your site a week ago, a page you deleted yesterday is still in there. This is a snapshot limitation shared by every pre-crawl index, from the cheapest tool to the most expensive suite. It is the cost of the model, not a defect unique to one brand.
The honest cost is acting on old data
The problem is not that a snapshot exists. The problem is deciding as if it were live. If a metric says a page still exists when you already removed it, you can waste an afternoon chasing a link that is already gone. If a score has not moved in months, you cannot tell whether your work is landing or whether the number is simply stale. For a small business owner, that is real time and real money spent on a picture of the web that has already changed. The reviewers are not wrong to be frustrated. They are describing the gap between the number on the screen and the site as it is right now, and that gap is where bad decisions get made.
Where reading the live page changes the math
We should state our bias plainly, because we built AuditLamp around this exact gap. When you run our audit, the engine fetches your page live at scan time and reads it the way Google and the AI answer engines read it (see what GEO means), then scores what is actually there right now. There is no aging index in the middle. What you see is what our crawler saw seconds ago, timestamped, not a cached estimate from a crawl that ran who knows when. To be fair about the limits of our own model: reading your live page is the right tool for on-page and AI-readiness findings, but it does not build the historical, whole-web link index that a big crawler maintains, and we do not pretend it does. For the question "is this page correct and ready today," fresh beats cached. One complete audit is $10, once, all 73 checks, no subscription and no card kept on file. More on that model in SEO tools with flat pricing and no credit meters, and if the sticker price is what pushed you to look elsewhere, Semrush too expensive? Honest alternatives.
Frequently asked questions
Is Moz data accurate?
Moz reads what is on your page, but its headline metrics and its link index are built from a crawl on its own schedule, so they are a snapshot that can lag. Treat any pre-crawl metric as an estimate. Verify against Google Search Console, which reports your own first-party data for free.
Why does Moz show pages that were deleted long ago?
Because a tool that pre-crawls the web stores what it last saw. If it has not re-crawled your site recently, its stored copy is out of date. This is a limitation of any cached index, not something unique to Moz. Make sure removed URLs return the right status codes and your sitemap is current so crawlers update faster.
Is stale data a Moz problem or an industry problem?
It is structural. Every tool that pre-crawls and caches the web, then sells you metrics from that store, shows a snapshot that can be days, weeks, or longer out of date. It is a trade-off, not a scandal. Reading the live page at scan time avoids the lag for on-page and AI-readiness findings, though it will not replace the historical link index a big crawler builds.
