The short version

  • Only Moz has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Optimizely no pricing is published and no minimum is stated
  • They diverge on capability: Moz covers Keyword Explorer, Optimizely covers A/B testing.
  • 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.

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.

Optimizely

  • No pricing is published and no minimum is stated
  • Every plan is individually packaged, so no two quotes are necessarily comparable
  • Reaching a figure requires a demo or sales conversation

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.

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