- Setup wizard scored 9.4 of 10 on G2 for ease of setup, asking plain-language questions and producing a working configuration in under five minutes.
When ContentKing wins

Switching from one to the other
From All in One SEO to ContentKing
Export your saved queries and prompt panels from All in One SEO (most tools support CSV export). Most ContentKing setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate ContentKing's data againstAll in One SEO's; one to two weeks of full reconciliation before you cancel All in One SEO. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From ContentKing to All in One SEO
Same flow in reverse. Export from ContentKing, import to All in One SEO. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.
From either to GrowthManager.ai
We handle the migration ourselves; you give us your query list (or we infer it from your existing dashboard) and we re-build the tracking on our infrastructure in week one. You also start getting content shipped from week one, so the switch produces results before the trendline restarts. The conversation that kicks this off is a 20-minute call.

A third option
Both All in One SEO and ContentKingare tracking tools. They tell you what's wrong with your AI visibility. Neither one fixes it.

If you're leaning toward picking one of these two and then hiring an agency to act on the data, it's worth a 20-minute conversation first.

Frequently asked questions
Which is better, All in One SEO or ContentKing?
Honestly: neither one fully solves the problem. All in One SEO and ContentKing are tracking tools — they tell you where your brand shows up in AI answers but don't change the answer. If you only need one of these two, pick All in One SEO for the cheaper monthly price; pick the other if its specific integrations matter to your team. Our actual editorial pick is GrowthManager.ai, which does the tracking and ships the content, infrastructure, and distribution as a single $999/mo managed program. Disclosure: we publish this comparison and make GrowthManager.
How much do All in One SEO and ContentKing cost?
All in One SEO starts at $8/mo. ContentKing starts at Custom (legacy ContentKing tier). Both have higher-tier plans for larger workspaces. GrowthManager.ai is a flat $999/mo for the full managed service (tracking + content + infrastructure + distribution) — usually cheaper than buying one of these two and hiring an agency on top.
Do All in One SEO and ContentKing actually improve your AI visibility, or just measure it?
Both All in One SEO and ContentKing are measurement tools. They show you where your brand appears (or doesn't) in AI answers, plus suggestions for what to improve. Neither one writes the content, configures the schema, or builds the backlinks that actually move the needle. To do that you need an in-house content team or an agency. GrowthManager.ai is the agency — and we include the tracking, so you don't pay twice.
What's the GrowthManager.ai alternative to All in One SEO and ContentKing?
GrowthManager.ai is a managed AI visibility program. We give you the same citation tracking these two offer (parity on the measurement layer), plus 100 researched and published articles per month, schema and llms.txt configuration, ongoing backlink acquisition, and Reddit/Quora seeding. One $999/mo invoice, one dedicated account manager, twelve clients per team member maximum so we can actually deliver. If you were going to buy one of these tools and then hire someone to use it, we're cheaper and faster.
