Frequently Asked Questions
Is SAGIScan a replacement for SEMrush?
Not entirely. SEMrush is an all-in-one marketing platform (backlinks, keywords, PPC, content). SAGIScan is a specialized website scanner that goes deeper on auditing with AI — especially for AEO and GEO, which SEMrush doesn't cover. Many users use both.
Why doesn't SAGIScan include backlink analysis?
Our philosophy is depth over breadth. Building a backlink index requires crawling billions of pages — that's a different product. We focus all 175 AI agents on analyzing YOUR website's on-page, technical, AI-readiness, and compliance factors with unmatched depth.
Is SAGIScan cheaper than SEMrush?
For website auditing specifically, yes. SAGIScan costs $5/page as a one-time payment. SEMrush starts at $129.95/month. If you only need auditing (not keywords/backlinks/PPC), SAGIScan saves you $1,500+/year.
