What GEO, AEO, and traditional SEO each reward, and how they fit together.
The SEO stack for the AI era. 60-second audits across Google, ChatGPT, Claude, Perplexity, and Gemini. Built for founders and the teams they grow into.

Engine coverage varies by plan. See what each plan tracks.
Drop a URL. Sixty seconds later: a JustScore, a prioritized fix list, the technical detail to ship the fix yourself.
High / Medium / Low. No 200-page PDF. Just what to fix this week, ordered by impact.
Broken links, duplicate content, missing meta, indexability issues, all surfaced in one crawl.
Each issue becomes a to-do. Each to-do has a copy-pasteable fix. Ship it, mark it done.
Track up to 150 prompts your customers are typing into AI search. Watch your share of voice, sentiment, and citations move week over week, across the AI engines we track, automatically.
Share of voice is the slice of AI answers that mention you for the prompts that matter. We chart it across the AI engines we track so you watch momentum build, not a one-off snapshot.
Sero reads your latest scan and answers in plain English: which fix has the highest ROI, why this page is losing AI mentions, what to write next. AI Chat 2.0 with memory and SEO backbone, available on Max.
No generic advice. Sero sees your scan, your crawl, your AI visibility data. Answers are specific to your site.
Diff-style edits you can ship. Code blocks, schema snippets, paragraph rewrites. Not 12 paragraphs of SEO theatre.
Remembers what you fixed last week. Tells you what moved. Tells you what didn't.
