Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
Semrush
Keyword and competitor research at agency depth
Semrush is the tool an SEO reaches for when they need to know what a competitor ranks for and what it is worth. Position tracking, site audits and keyword gaps are all there, along with newer reporting on how brands surface in AI answers. It costs more than most creators can justify, and the entry plan tracks five sites and 500 keywords.

Surfer
Write the page against what is already ranking
Surfer reads what currently ranks for a term and turns it into instructions while a draft is being written: length, headings, and the terms the page is missing. It now tracks how often a brand appears in AI answers alongside its position in search. The cheapest tier exists to test the workflow on a small number of documents. Anybody expecting a rank tracker or a crawler is buying the wrong tool, because this is aimed at the writing rather than the site.
Our note
Start on Discovery and only move up when the document count runs out, because the jump to Standard doubles the price for capabilities most solo publishers never open. The AI visibility tracking is the genuinely new part of this product and the reason to prefer it over the older on-page tools.
