Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Moz

Moz refreshes its link index less often and discovers fewer links than Ahrefs, so a new backlink frequently appears in Ahrefs days before it shows up in Link Explorer, which matters if link acquisition reporting is your job.
Rank tracking is weekly on every tier, so a site watching a volatile SERP or validating a same-week change cannot see daily movement without buying a separate rank tracker.
The Standard plan allows only 150 keyword queries a month, which a single afternoon of research exhausts, and the jump to a workable 5,000 queries means paying 179 USD a month rather than 99.
Almost every limit is separately metered and separately billable: extra seats are 49 USD each, campaigns 10 USD, tracked keywords 20 USD per 200, crawl capacity 15 USD per 50,000 pages, so the real bill drifts well above the plan price.
Domain Authority is a Moz score, not a Google ranking factor, and teams that optimise for it directly are optimising for a proxy that its own vendor sells.
Moz Local is a separate subscription per location, so a business with twenty sites is buying a second product at twenty times the per-location price on top of Moz Pro.

VWO

Growth plan restricted to 1 workspace and 0 custom attributes
Single Sign-On (SSO) and API access limited to Enterprise tier only

Moz: Is Moz or Ahrefs better?

Ahrefs is the stronger choice for backlink depth, index freshness and competitive research, and its Lite plan is 129 USD against Moz Standard at 99. Moz is the better buy if you need Domain Authority as a reportable metric, if local listings management matters, or if 49 USD a month for a single site is the budget.

VWO: Are there limits on users or metrics?

Run unlimited optimization at scale with no limit on variations, account users, metrics, session recordings, or integrations.

Moz: What do the Moz free tools give you?

Free Domain Analysis with Domain Authority, limited Keyword Explorer and Link Explorer queries, Competitive Research, a Brand Authority check and MozCast volatility tracking. Campaigns, site crawls and rank tracking all require a paid plan.

Moz: Is Domain Authority a Google ranking factor?

No. It is a Moz model that predicts ranking strength on a 1 to 100 scale. Google does not use it. It is useful as a comparative shorthand, not as a target.

Moz: How often does Moz update rankings?

Weekly on every Moz Pro tier. Competitors such as SE Ranking update daily as standard.
