The Best SEO Tools

Five SEO suites compared on keyword data, backlinks, rank tracking and value — with a clear pick for most marketers.

Last updated Jul 3, 2026

An SEO suite lives or dies on its data, but the right one depends on whether you need the broadest all-rounder, the best backlink index, or the most affordable toolset for a small site. We compared the five platforms SEO professionals shortlist most and scored each on the data and features that actually move organic traffic, so you can pick by fit rather than marketing.

How we scored this

We score every tool on four weighted criteria: Keyword Research & Data (weight 3), Backlink Index & Analysis (weight 2), Rank Tracking & Audits (weight 2) and Value for Money (weight 1), because SEO decisions are only as good as the data behind them. Rankings reflect our editorial assessment against these criteria and are independent of any affiliate payout — sponsored placements, where they appear, are always labelled and never presented as an earned rank.
