PrePostSEO
SEO AuditFree toolkit with 95+ basic SEO utilities and checkers
Overview
PrePostSEO positions itself as a comprehensive free alternative to paid SEO tools, offering 95+ utilities that cover most basic SEO tasks. Founded in 2017, the platform aggregates simple tools that many SEOs need occasionally but don't want to pay monthly subscriptions for. The tool collection spans technical auditing, content analysis, backlink checking, and various calculators.
The platform targets budget-conscious users, students, and small businesses who need occasional SEO analysis without enterprise-level features. While the breadth is impressive, the depth of analysis remains surface-level compared to dedicated tools like Ahrefs or Semrush. Most tools process single URLs or small batches rather than full-site analysis.
PrePostSEO's main value proposition is accessibility — no signup required for most tools, instant results, and genuinely free access to functionality that competitors charge for. However, this comes with significant limitations in data quality, processing speed, and feature sophistication.
