As an indie founder, $139.95/mo for an SEO tool is a real line item. After Adobe bought Semrush for $1.9B and expanded the keyword DB to 280B, I ran a 30-day test across audits, PPC and social. Verdict: the all-in-one coverage is genuinely strong, but entry plans are single-seat and the content tools are paywalled behind the $249.95 Guru tier.
