The short version

  • 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.; PostHog the free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • They diverge on capability: Moz covers Keyword Explorer, PostHog covers Product analytics.
  • 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.

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier

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.

PostHog: How much data retention does PostHog provide on paid plans?

PostHog free tier provides 1-year data retention. Pay-as-you-go plans offer 7-year data retention across all projects, enabling longer historical analysis. Source: https://posthog.com/pricing

Source
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.

PostHog: What percentage of PostHog users stay on the free tier?

PostHog states that 97% of companies use PostHog for free, indicating extensive free tier adoption. However, specific per-unit pricing rates for overages on paid plans are not published. Source: https://posthog.com/pricing

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.

PostHog: When does PostHog provide priority support on paid plans?

PostHog provides email or Slack support for accounts exceeding $2,000/month on pay-as-you-go plans. Specific response times and support SLAs are not detailed on their pricing page. Source: https://posthog.com/pricing
