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.
SimilarWeb
- Browser extension data accuracy is lower than full platform
- Full platform pricing is not transparent and requires quote-based inquiry
