Which one is for you
Pick Ahrefs if
- Fits if most of your SEO time goes on backlinks and what's ranking for rivals
- Works for site owners who only need data on their own verified site, which Ahrefs Free covers
Look elsewhere if
- Skip it if you want daily rankings, as Rank Tracker updates weekly on every plan
- Pricey if you're a small business, at about $107.50 a month for Lite even paid yearly
- Tight if you research a lot on Lite, where each user gets 1,000 credits a month; Starter gets 200
- Pricey if you add people: each plan has one user, and extras cost $40 to $80 a month, capped at 2, 5 or 10
- Watch out: AI writing tools start at $99 a month on top, and there's no trial of any paid plan
Pick OpenSEO if
- Fits if you already do your SEO work through Claude, Codex or another AI agent
- Works for developers who want to self-host or build on open-source SEO code
Look elsewhere if
- Tight if you research a lot, as $10 of usage is about 200 keyword searches and more is bought as top-ups
- Watch out: plan credits reset each billing cycle, and top-ups only work while you have an active subscription
- Watch out: the hosted service adds a 28% fee on DataForSEO requests
- Skip it if you want self-hosting to be free, as you still pay DataForSEO, with a $50 minimum top-up
- Skip it if you need AI tracking beyond ChatGPT, Gemini and Google AI Overviews

|---|---|---|
| Value for money | DLite, the plan Ahrefs aims at small businesses, is $129 a month, or $1,290 a year (about $107.50 a month) with the yearly saving.

Starter is $29, but it's monthly only with 200 credits. | A$10 a month with $10 of usage included, under 60% of this category's cheaper quarter.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
