AI SEO tools by category

SEO covers several different jobs, and the tools follow those jobs. This page lists every category on SEO Opinion with the number of tools in each, so you can go straight to the part of the work you are planning. Each category page explains what that kind of tool does, what to check before you pay for one, and the questions people ask most, followed by the tools themselves.

If you are starting from nothing, begin with technical SEO and site audits, where Google's free tools live, then keyword research. Those two tell you what Google sees on your site and what your audience searches for. Content optimization and AI writing come next, once you know which pages to create or improve. Rank tracking and reporting help you see whether the work is paying off.

Links and outreach, local SEO and AI search visibility are more specialized. Local SEO matters most for businesses that serve customers in a particular area. Link building suits sites in competitive fields where the top results all have strong link profiles. AI search visibility is the newest group, for brands that want to know how assistants such as ChatGPT and Perplexity describe them.

All-in-one suites overlap with most of these categories, which is why many teams buy one suite and add a specialist tool where they need more depth. Every tool page links to the official site, where you can check current plans and features before signing up.

Every listing follows the same pattern: what the tool does in one line, who makes it, a link to the official site and a short set of facts such as a free plan, an API or a WordPress plugin, marked only when we could confirm them. Some well-known tools have a longer write-up. Use the search page to look for a tool by name, or the category pages to compare tools that do the same job side by side.
