SEO tools let you research keywords, track rankings, audit your site, monitor backlinks and competitors, and measure visibility in AI search results. We evaluate the depth of the backlink or keyword index, the free or trial option, how the bill scales (by credit pool, tracked keywords, site count or user seat), what the AI-visibility add-on actually tracks, and whether the tool is a full platform or a single-purpose specialist.

When you compare SEO Tools tools, the fields that decide the outcome are the ones this index actually stores: whether a free plan exists and what it limits, the published entry price and how it bills (per seat, per month, per workspace), what the trial covers, which of the six index dimensions the tool scores on, when each figure was last checked against the official page, and which alternatives sit in the same category. Each tool page prints those fields with its own verification date, the SEO Tools comparison pages put two products side by side on the same fields, and the list pages rank the category against the rest of the index — so you can move from a shortlist to a decision without opening a vendor's sales page.
