The short version

  • Each has a real cost: Ahrefs the April 2024 move from unlimited usage to credits was a real downgrade for existing customers: Lite meters 1,000 credits per user per month and the data tools lock when they are gone, so heavy research on the entry plan now forces an upgrade to Standard at 249 USD.; SEMrush free tier limited to 10 reports per day across all tools
  • They diverge on capability: Ahrefs covers Site Explorer, SEMrush covers Site audit.
  • 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.

Ahrefs

  • The April 2024 move from unlimited usage to credits was a real downgrade for existing customers: Lite meters 1,000 credits per user per month and the data tools lock when they are gone, so heavy research on the entry plan now forces an upgrade to Standard at 249 USD.
  • Pay-as-you-go credits are charged automatically once enabled, so a busy research month can produce an unbudgeted overage bill rather than a hard stop.
  • Every paid tier includes exactly one user, and additional seats cost 40, 60 or 80 USD a month by tier, so a three-person team on Standard pays 369 USD a month rather than 249.
  • Row caps bind before credit caps for many jobs: Lite returns at most 2,500 rows per report, which is not enough to export a mid-sized site backlink profile in one pass.
  • Ahrefs states plainly that it never runs discounts and offers no free trial of the paid plans, so evaluation means paying a full month or working from the ownership-verified free tier.
  • Rank Tracker updates weekly on every tier including Enterprise, so teams needing daily positions have to buy a separate tracker such as SE Ranking or Semrush.
  • A growing share of capability is sold as add-ons rather than included: Report Builder at 99 USD a month, Content Kit from 99 USD, Project Boost at 20 or 200 USD per project, and Brand Radar from 199 USD.

SEMrush

  • Free tier limited to 10 reports per day across all tools
  • Keyword tracking capped at 500 per month on entry tiers (SEO and Starter plans)
  • Additional users cost £45/month per user above base subscription
  • Most advanced features require Advanced plan (£455.67/month), making entry cost significant for small teams

Answered from the vendors’ own pages

Starter is 29 USD a month, Lite 129, Standard 249, Advanced 449 and Enterprise 1,499 with an annual commitment. Paying annually saves up to 17 percent, which Ahrefs describes as two months free, and it is arranged through support rather than on the site.

Semrush starts at $117.33/month for the SEO Plan with annual billing and goes up to $455.67/month for the Advanced Plan. A free tier is available with 1 demo project and basic features. Prices increase with monthly billing instead of annual.

Ahrefs: What are Ahrefs credits and when did they start?

Ahrefs replaced unlimited report usage with credits in April 2024. It meters report credits, crawl credits and API units. Lite includes 1,000 credits per user per month; Standard and above are unlimited under a fair use policy. Purchased pay-as-you-go credits last three billing months.

SEMrush: What does each Semrush plan include?

Plans scale from 5 to 40 websites monitored, 500 to 5,000 keywords tracked daily, and include progressively more features like MCP access and API access at higher tiers. Advanced Plan includes dedicated support.

Source
Ahrefs: Is Ahrefs or Moz better?

Ahrefs has the deeper and fresher link index and stronger competitive research, and it is the default for link work. Moz is cheaper at entry, owns Domain Authority as a reportable metric, and has a real local listings product. If you report DA to clients or manage multi-location listings, Moz earns its place; otherwise Ahrefs wins on data.

SEMrush: Are there add-on options for Semrush?

Yes, additional users cost $45/month, and reporting features range from $10-$20/month. Enterprise plans with unlimited projects and dedicated support are available with custom pricing.

Source
Ahrefs: Is there a free version or a trial?

There is Ahrefs Free, limited to Site Explorer and Site Audit on sites you verify you own, so it gives you no competitor data. Ahrefs states it never runs discounts and does not offer a trial of the paid plans.

Ahrefs: How many users are included?

One, on every paid tier up to Advanced. Extra seats cost 40 USD a month on Lite, 60 on Standard, 80 on Advanced and 100 on Enterprise, and unpaid additional users are billed automatically as pay-as-you-go.
