Semrush is the industry-standard marketing intelligence suite — exhaustive data on keywords, backlinks, ads, social, and competitors. It gives you data; you do the work. SEOArchitect uses comparable data feeds (DataForSEO live + market intelligence) but layers 12 AI agents on top to actually execute the SEO workflow under your approval.
No marketing spin — what each tool actually does in 2026.

You're a large enterprise marketing team that needs PPC tracking, social-media analytics, and white-paper-grade keyword databases more than you need execution help. You have a team of analysts already running the workflow manually.
You're a founder, solo SEO, or small agency without a 5-person research team. You want the data + the agents that turn data into briefs, drafts, and publishes — not a 50-tab dashboard you'll never fully use.
