Ahrefs vs Semrush
They differ on 4 of the 15 things buyers in this category actually ask about. Here is where, and what each one asks you to give up.
Ahrefs
$129The backlink index everyone benchmarks against, plus solid keyword and content tooling.
Strongest argument
The largest and freshest backlink index of any tool in this category
Biggest objection
No free trial — you commit a month before you can evaluate it properly
You pay a premium for index quality, and the seat model punishes teams rather than solo operators.
Semrush
$139.95The broadest toolkit in SEO, stretching into paid search, social and content marketing.
Strongest argument
Covers organic, paid, social and content in one subscription
Biggest objection
Add-ons mean the real monthly cost is routinely double the headline price
The all-in-one option, priced so that the all-in-one bill is a lot larger than the sticker.
The differences that matter
Where they actually diverge
Only the rows where the two disagree. Everything they both do is listed below.
Cost
What each costs at 50 people
List price only. It ignores add-ons, seat minimums and the cost of the move itself — all of which routinely dwarf the difference below.
Prices are unverified estimates — useful for comparing orders of magnitude, not for budgeting. Confirm the current figure with the vendor before you commit to anything.
Common ground

Questions
Ahrefs vs Semrush, answered
Ahrefs or Semrush — which is better?
Neither, in the abstract. Ahrefs suits you if the largest and freshest backlink index of any tool in this category matters most; Semrush if covers organic, paid, social and content in one subscription does. The honest trade-offs are: Ahrefs — You pay a premium for index quality, and the seat model punishes teams rather than solo operators. Semrush — The all-in-one option, priced so that the all-in-one bill is a lot larger than the sticker.
Is Ahrefs cheaper than Semrush?
Ahrefs is cheaper at 50 people — $129/mo against $139.95/mo, roughly $1,548 against $1,679 a year. That gap of about $131 is rarely the whole story though — add-ons, seat minimums and the cost of migrating routinely outweigh it.
Can we migrate from Ahrefs to Semrush?
Usually yes, and the difficulty depends on history, integrations and headcount far more than on the two products. Data export quality is the thing to check first: ask both vendors what you can take with you before you commit to either. Our questionnaire produces a scoped estimate for the move.
What else should we consider besides Ahrefs and Semrush?
In seo tools the other credible options are Moz Pro, Screaming Frog, Ubersuggest. Narrowing to two before you have written down your requirements is the most common way to end up with the wrong one.
