Best SEO tools
A note on what is absent: Ahrefs and Semrush are tracked daily but publish their prices in ways our extraction does not yet hold as a named ladder, so they are excluded rather than guessed. Every figure below was read from the vendor's own pricing page on the date beside it. The ordering is cheapest entry price first — a basis you can check rather than a ranking you have to trust.
What “best” means on this page
“Best” is not a mood — it is whichever axis you actually care about, measured. Our record can say which tool is cheapest to start, whose free plan is real, who bills local currency and whose prices just moved; it cannot say which tool fits your work, which is what the full comparisons are for. Cheapest never means best — it means cheapest. Each verdict below names its axis, and every tool links to its own site so you can check us against the source. No vendor paid for any position.
Entry at €37/mo — the lowest published paid plan in this set. Cheap is a fact, not a verdict; the profile below says what you get for it.

Billed in another currency
These tools are in the same category but did not show us a price in EUR on our last read — they quote the currency shown. We list them rather than convert: a converted figure is not a price anyone is charged.
SpyFusite ↗pricing ↗
A competitor research tool that shows the keywords and ads rivals have bought and ranked for, historically. Paid plans start at $39/mo (Basic); no free plan is published. The ladder we hold runs 3 paid tiers, topping out at $249/mo (DATA). We read the same $39/mo in every market we check, so this vendor does not price by country. It quotes USD here rather than local currency, so your bank sets the conversion.
Mozsite ↗pricing ↗
An SEO toolset covering keyword research, link data and site audits, and the origin of the Domain Authority metric. Paid plans start at $99/mo (Standard); no free plan is published. The ladder we hold runs 3 paid tiers, topping out at $299/mo (Large). We read the same $99/mo in every market we check, so this vendor does not price by country. It quotes USD here rather than local currency, so your bank sets the conversion.
Ahrefssite ↗pricing ↗
An SEO toolset built on its own web crawler — backlinks, keywords, rank tracking and site audits. Paid plans start at $129/mo (Lite); no free plan is published. The ladder we hold runs 4 paid tiers, topping out at $1499/mo (Enterprise).
