Best free SEO tools (and where SEOHub fits)

“Best” depends on the job. Here’s an honest split between free research, free technical checks, and when a paid crawl is worth it.

The honest take

For a weekly health check of your own site, start with SEOHub’s free homepage preview and technical tools — no account.

For deep backlink or enterprise keyword research, free tiers of large suites (Ahrefs, Semrush) are limited; paid research seats still win there.

Pair free Google Search Console + Analytics with a crawl checklist so you fix what you measure.
