Pricing

Backlinko's own SEO tools and articles/guides/templates are presented as free. The site separately promotes a 14-day free trial of Semrush's paid tool suite (55+ tools, described as 'free access for core features'), but that trial and pricing belong to Semrush, not to a Backlinko-branded paid plan.
