The short version

  • Only Moz has a free tier, so it costs nothing to try first.
  • Each has a real cost: Keyword Insights it has no keyword research or search volume data of its own; keywords must be exported from another tool such as Ahrefs or Search Console first.; 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.
  • They diverge on capability: Keyword Insights covers SERP-based clustering, Moz covers Keyword Explorer.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Keyword Insights

  • It has no keyword research or search volume data of its own; keywords must be exported from another tool such as Ahrefs or Search Console first.
  • SERP-based clustering requires a live Google SERP pull per keyword, which is why it is credit-metered and can get expensive fast on very large keyword lists.
  • The pay-as-you-go credit tier only covers clustering; content briefs and other features require a full subscription, which is easy to miss when comparing the entry price.
  • It has no rank tracking, backlink data or technical crawling, so it is a single-purpose tool that must sit alongside a broader SEO stack.
  • As a small, specialised vendor, its roadmap and support resourcing are thinner than a full suite like Semrush that bundles clustering as one feature among many.

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.

Answered from the vendors’ own pages

Keyword Insights: Do I need another SEO tool to use it?

Yes, for keyword data. Keyword Insights clusters and classifies keyword lists you supply; it does not generate keyword lists with search volume itself.

Moz: How much does Moz Pro cost?

Starter is 49 USD a month for a single site. Standard is 99 USD a month or 79 USD billed annually, Medium 179 or 143, and Large 299 or 239. Moz lists first-year annual totals of 950, 1,719 and 2,868 USD respectively.

Keyword Insights: How is pricing calculated?

By credits, at 1 credit per keyword clustered, either through a monthly subscription with a credit allowance or a pay-as-you-go top-up.

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.

Keyword Insights: Is there a free tier?

No permanent free tier; a 7-day trial for 1 US dollar is offered instead.

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.
