How to choose an AI SEO tool
Start from the job you need done, then compare price. Most of these tools have a free plan or a trial, so test one on your own site before you pay.
You want one tool for research, audits and rank tracking
Semrush combines keyword, backlink, audit and market data in one suite, with a free account. Its AI search tracking comes with Semrush One Starter or the AI Visibility Toolkit, sold on its own at $99 a month per domain. SE Ranking covers the same core jobs for less, and its Core plan already tracks 100 AI prompts a day. Ahrefs is our pick for backlink research; its Brand Radar AI tracking starts at $50 a month for your own prompts.
You write content and want it to rank
Surfer SEO scores your drafts as you write, from $49 a month billed yearly. Clearscope suits editorial teams, because every plan includes unlimited users. MarketMuse helps plan content topics and briefs; it has a free plan, and its paid plans are priced on a demo call. Our SE Ranking vs Surfer SEO comparison helps if you are torn between a suite and an editor.
You want to track your brand in AI answers
SE Ranking's Core plan already tracks AI answers, and Semrush adds AI tracking with Semrush One Starter or its AI Visibility Toolkit, so start there if you use them. For dedicated trackers such as Rank Prompt, Rankscale and HubSpot AEO, see our AI visibility tools page, which compares them by AI engines, prompts and price.
You want fixes applied for you
Search Atlas uses its OTTO assistant to deploy page optimizations you approve, from $99 a month on monthly billing. Alli AI applies on-page changes across several sites and serves AI crawlers a pre-rendered version of your pages. Ranked AI goes further: its team writes content, builds links and optimizes pages for you, priced per website. Our Semrush vs Search Atlas comparison weighs automation against a classic suite.
SEO, GEO and AEO: what is the difference?
SEO tools help your pages rank in Google. GEO (generative engine optimization) and AEO (answer engine optimization) tools track and improve how AI assistants such as ChatGPT, Gemini and Google AI Overviews mention and cite your brand; we compare them on our AI visibility tools page. Several suites on this page now do both, so check which AI engines a plan covers before you buy.
