What is SEO?
AI SEO tools use AI to do the heavy lifting of search optimization — keyword research, content briefs, on-page optimization, technical audits and, increasingly, tracking how your brand shows up inside AI answers. Instead of stitching together spreadsheets and separate checkers, you get one workflow that suggests what to write, grades it against what ranks, and monitors the result.
The tools here split into a few jobs. Content-and-optimization platforms like Search Atlas, SEO.ai, Rankability and Koala AI handle keyword research, writing and on-page scoring, several with free trials. Prepostseo bundles a large set of free SEO utilities. A fast-growing group tracks AI-search visibility: Otterly.ai and LLMrefs monitor how often your brand and pages surface in AI Overviews and chat answers — a job classic rank trackers were never built for.
Picking a stack depends on your goal. If you publish a lot, a content-optimization tool that grades drafts against the SERP earns its keep. If you run an agency, platforms built for scale and reporting fit better. And if your traffic is starting to leak to AI answers, add a visibility tracker so you can see — and defend — how you appear there. Many offer free tiers or trials, so test on your own keywords before committing.
