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.
SpyFu
Every keyword a competitor has bought or ranked for
SpyFu is built around one question: what is the other site doing. It keeps more than a decade of history on which keywords a domain ranked for, which ads it ran and what it paid, which is the part the general SEO suites treat as a side feature. For research on a competitor rather than maintenance on your own site, it is the cheaper specialist.
Our note
SpyFu is the cheap way to answer one question well: what is the competition ranking and bidding on. Pair it with a free rank tracker rather than treating it as a replacement for a full SEO platform.
Only on this side
- Covers research & trends
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.
