SEO

What are seo tools?

SEO tools span keyword research, competitor analysis, backlink monitoring, on-page audits, and rank tracking. Enterprise suites like Ahrefs and Semrush cost hundreds per month, but a thoughtful free stack gets a bootstrapped founder 80% of the insight at zero cost. This list picks tools with real free tiers — not 7-day trials disguised as free plans.

Who this list is for

Founders doing their own SEO, content marketers validating topics before writing, and operators auditing a site before hiring an agency.

How we picked

• Free tier shows real search-volume and difficulty data
• No artificial query caps that block normal research
• Exports to CSV for offline analysis
• Updated index — stale data is worse than no data

Buyer's guide

Start with one keyword tool and one site-audit tool. Run the audit monthly, research keywords weekly, and resist paying for an enterprise suite until you have content live and ranking. Most founders pay for SEO software before they have content worth optimizing.
