Semrush is the benchmark. For teams running SEO at scale with a single platform budget, it wins the comparison more often than not — not because any single feature is the best, but because the breadth reduces context-switching.

The AEO gap is real but expected: Semrush was built for ten blue links and pivoted toward AI search as the landscape shifted. AI Overviews tracking is present but LLM citation visibility (ChatGPT, Perplexity) is absent. If AEO is your primary mandate, layer a purpose-built tool on top.

Use Semrush for your SEO foundation. Treat it as complementary to AEO tooling, not a replacement.
