Which GEO tools does ChatGPT recommend this week?

Semrush leads the GEO chart this week — the AI-visibility tool ChatGPT itself mentions most, with a DECA Score of 100.0 across 44 tracked brands. The table above shows the full ranking.

How is this GEO tools ranking calculated, and how often does it update?

Weekly, we ask ChatGPT what brands typically ask — how to track mentions in AI answers, which GEO platform measures AI visibility — and score every tool it names by frequency and prominence. The methodology page covers the scoring in depth.

What changed in this week's GEO tools ranking?

Writesonic climbed 8 spots to #10 — the sharpest rise of the week. Keyword.com entered the chart for the first time.

What should a GEO tool actually measure — mentions or citations?

Both, ideally. A mention is when AI names a brand in its answer; a citation is when it links a source. Strong GEO tools track the two separately — and this chart ranks GEO tools by how often ChatGPT itself brings them up.

How do I use this chart?

Signal cards first — Leader, Top Mover, New Entry — then the table: weekly movement (▲▼), DECA Score, Mention Rate. Use segment filters to narrow, the week selector to compare weeks. If your GEO tool isn't tracked, add it free and it appears next run.
