Ahrefs is a large toolkit for researching the whole web. Duality is a smaller tool that tracks your own sites and reports on them. Here is what each does well, and what each costs.
We make Duality, so we are not neutral. We have kept to facts that Ahrefs publishes itself, and we say where Ahrefs does more than we do.
Plenty of people use both: Ahrefs to research, Duality to keep watch and report.
Its Site Explorer and Keywords Explorer let you look into competitors' sites and keyword ideas, not only your own. On the higher plans it adds Content Explorer and Batch Analysis.
Its plans go up to thousands of tracked keywords and dozens of projects, with extra users, up to five years of history on the Advanced plan, and an API from its Lite plan.
Ahrefs Free covers sites you verify, with Site Audit, Web Analytics and a limited view of Site Explorer. It is a real way to try the brand without paying.
Every site's keywords are checked on desktop and mobile, in the country or city you choose. Search Console clicks, Analytics visits and PageSpeed scores sit in the same weekly and monthly report.
Each site gets a private share link with your logo and details and no Duality name. White label sharing is on every plan, at no extra cost. See how it works.
Plans start at £9 a month plus VAT. A monthly Site Audit with a Health Score is included in every plan, and the 21 day free trial needs no card.

Ahrefs details are from its pricing page and help centre, read on 11 October 2026. Ahrefs changes its plans from time to time, so check its pricing page before you buy.
This compares how many sites and keywords you can track. It does not compare tools: Ahrefs includes research that Duality doesn't.
| What you track | Duality, a month | Ahrefs, a month |
|---|---|---|
| 1 site | Lite: £9 plus VAT. 1 site, 30 keywords. | Lite: £99. 5 projects, 750 tracked keywords. (Its Starter plan is £23 and much smaller.) |
| 3 sites | Pro: £24 plus VAT. 3 sites, 60 keywords each. | Lite: £99. 5 projects, 750 tracked keywords. |
| 10 sites | Scale: £59 plus VAT. 10 sites, 100 keywords each. | Standard: £199. 20 projects, 2,000 tracked keywords. |
| 20 sites | Max: £119 plus VAT. 20 sites, 125 keywords each. | Standard: £199. 20 projects, 2,000 tracked keywords. |
| Thousands of keywords | Not what it is built for. Keywords are capped per site by plan. | Advanced: £359, 5,000 keywords and 50 projects. Extra keywords come in batches of 500. |
Duality prices exclude VAT. Ahrefs' pricing page doesn't say whether its prices include tax, and it shows the currency for your location, so what you see may differ. Ahrefs offers a saving of up to 17% when you pay annually.
Ahrefs counts a tracked keyword once for each location in each project. Duality's keyword numbers are per site, and each is checked on desktop and mobile. See all Duality plans.
If any of these matter to you, Ahrefs is the better fit.
Duality tracks the sites you add. It has no tool for browsing any website's links, top pages or keywords, apart from the single competitor lookup in the Keyword Research add-on.
Rankings are checked down to position 30, in English. Past that, the report says "not in top 30".
No team logins, no API and no daily rank checks. Keywords are capped per site, and the research add-ons are smaller than Ahrefs' own tools.
For one job, yes: tracking where your sites rank and reporting on it. For research on other websites, Ahrefs does far more than Duality, and we don't claim to replace that.
For tracking a few sites, usually. Duality starts at £9 a month plus VAT, and Ahrefs' list prices on its pricing page start at £23 for a limited Starter plan and £99 for Lite. The tools differ a lot, so compare what you need, not only the price.
Yes. Ahrefs can find keywords and competitors. Duality then tracks the keywords you pick and sends you and your clients a regular report.
No. You can't add a competitor to a site and follow their rankings. The Keyword Research add-on can look up one competitor's website and list the keywords it ranks for in the top 30, which counts as one of your monthly searches.
Yes, on every plan. Each site gets a private share link with your logo and details, and no Duality name on it. Read how white label reports work.
