The Bottom Line
Semrush is the category benchmark for keyword research, backlink analysis, and large-scale technical site auditing. If you depend on a 24B+ keyword database, deep backlink intelligence, content marketplace, and PPC research in one suite, Semrush at $139.95/mo earns the seat. The new AI Visibility Toolkit and AI PR Toolkit add credible AI search coverage to that workflow.
Foglift is the better choice if AI search readiness is your primary use case rather than a bolt-on. Foglift ships native GEO + AEO scoring from the free tier, an AI Crawler Tracker (which Semrush doesn't offer at any price), Claude and Gemini coverage with no per-engine fees, and a developer surface — REST API, CLI, MCP server — that's included on every paid tier rather than billed as a separate per-credit API plan.
The honest cost comparison for combined SEO + AI search isn't Foglift's $49/mo vs Semrush's $139.95/mo — it's $49/mo vs the $238.95/mo Pro + AI Visibility Toolkit bundle that Semrush itself recommends for this use case. That's a 79% reduction in monthly cost for the same job.
Best of both worlds: many teams pair them. Use Semrush for keyword/backlink/PPC research where it leads the category, and Foglift for the optimize-index-monitor-analyze-improve loop on AI search where Semrush's coverage is still bolt-on. Foglift Launch ($49/mo) added to a Semrush Pro account is cheaper than adding Semrush's own AI Visibility Toolkit, with broader engine coverage and an AI Crawler Tracker Semrush doesn't ship.
