If you only read one section, make it this one. Rows where both sides say the same thing are left out — the point is where they differ. Where each row came from is listed underneath.
| Category | Ahrefs | Semrush | Better fit |
|---|---|---|---|
| What it's built for | Its own crawler and index rather than a licensed one, which is why its backlink data is the reference point most others are compared against. | Real search data underneath the AI, so a keyword volume or a ranking is something you can check rather than something a model guessed. | Tie |
| Free plan | Yes. Ahrefs Webmaster Tools is free indefinitely, but only for sites you verify you own | Yes. Free account, capped at around ten results per report and ten reports a day | Tie |
| Cheapest way to pay | $29 a month. | $139.95 a month. | Ahrefs |

| Tie |
| What to watch out for | The free tier is Webmaster Tools and only works on sites you can verify you own — no competitor research without paying. | The free account is heavily capped — around ten results a report and ten reports a day — which is enough to evaluate and not to work. | Tie |

Ahrefs is ahead on 1 of the 6 rows compared — cheapest way to pay — and it is not about how well it does the job. On fitness for the work, it and Semrush are level. Treat this as a tiebreaker, not a recommendation.
Ahrefs
Its own crawler and index rather than a licensed one, which is why its backlink data is the reference point most others are compared against.
Real search data underneath the AI, so a keyword volume or a ranking is something you can check rather than something a model guessed.
Semrush is the better answer when the job is what it was built for rather than what the pick above does broadly.
How we know
Every row that separated these two, and where it came from. Nothing here is a hands-on test — if a line rests on a vendor’s own pricing page, it says so and links it.

The ratings
The category these two share. Marketing & Content Creation — both are listed there in the catalogue, and the fit recorded against each listing is a judgement made here, by hand.
The nine-category grid below. Derived from what each product is listed for, by one script, once per build — so the same pair always reads the same. It is a derivation, not a review.
What this is not
Neither product was run side by side to produce this page. Nobody was paid to appear on it and nothing here is ranked by commission.
To put the same question to both and read the answers yourself, run them side by side — that is a live test, and this is not.
Choose based on what you’re doing
All ten categories, including the ones where neither of these is the answer. These ratings are derived from what each product is listed for, not from running it — a rating here is a reading of the record, and the record is linked.
