Best AI SEO agents in 2026, compared by how much they do alone.
8 agents scored on what each does without a person: picking keywords, writing, checking facts, publishing, building links and reporting. Every price and feature comes from the vendor's own pages, read on 10 November 2026. No affiliate links, no paid placements.
What is an AI SEO agent?
An AI SEO agent takes the actions itself, from start to finish: it picks keywords, writes, checks, publishes and reports without a person doing each step. An AI SEO tool helps a person do one of those steps.
Want an agent that runs the whole job and checks its own facts? The SEO Agent picks keywords, writes one article a day with every claim checked against its sources, and publishes it when you approve. Enter your site to start.
US$1 for your first 3 articles, then US$99/month.

Checked 10 November 2026 on each vendor's own pricing and product pages. Prices in US dollars as each vendor shows them. Yes: the vendor’s own page says so for its entry plan. Partly: only on a higher plan, only part of the job, or a person does the rest. No: the vendor’s page does not claim it.
How we picked and ranked these eight.
We make The SEO Agent and rank it first. Here is why, and where it is not the best pick. It is the only agent here whose entry plan checks facts against sources, which is the job we weight as heavily as writing and publishing. It does not build links, and the section after the list names three cases where another agent fits better.
The other seven are the brands Google's AI answers named for our buyer questions about AI SEO agents and daily autopilot publishing, plus Frase, which sells an AI Agent by name, and Outrank, which we pay for. Each is ordered by a score from the autonomy table: picks keywords (15%), writes (20%), checks facts (20%), publishes (20%), builds links (10%), reports (15%). A yes counts in full, partly counts half and no counts zero, and ties go to the lower monthly price. Every cell describes the entry plan and comes from the vendor's own page, read on 10 November 2026.
Each entry carries an evidence label. We pay for Outrank, so that entry is first-hand; every other vendor is marked docs and pricing only, because we read its pages and did not run it. If an agent changes its plans, the change log at the bottom records it. For the wider field of tools that help with one step at a time, including optimizers and brief tools, see the SEO automation tools roundup.
The SEO Agent
EVIDENCE: We make it
We built The SEO Agent as an AI SEO agent for one job: a researched article on your site every day, with every claim checked against its sources before it can publish. It is the only agent here whose entry plan checks facts, and the only one that holds an article with a fact problem it could not fix for your review instead of shipping it.
One plan, US$99 a month for one site and 30 articles, and US$1 for your first 3 articles. It does not build backlinks or edit your existing pages; the section after the list says who should pick something else. Price, trial, connections and limits are on our product facts page, and our ranked list of AI SEO tools covers the tools that help a person with one step.
- What it automates
- Finds keywords, plans articles, writes one a day with cited sources, checks each claim, adds images, alt text, metadata and internal links, and publishes to your CMS
- How much you do
- Connect a site, review the content plan and approve drafts. Auto-publish stays off until you switch it on.
- Price
- US$99/mo for one site and 30 articles; extra sites US$79/mo (checked 10 November 2026)
- Trial
- US$1 for your first 3 articles (3 days)
- CMS connectors
- WordPress, Webflow, Shopify, Wix, Ghost, Framer, signed webhook
- Best for
- Founders and small teams who want a daily article with every claim checked
- Limits
- Does not build backlinks or edit existing pages; more than 30 articles a month on one site is arranged by email
- Evidence
- We make it
Outrank
EVIDENCE: We pay for it
The closest peer to ours, and the one we know first-hand: we pay for it, and its unedited articles run on our Outrank lab pages so you can read real output. It picks keywords, writes 30 articles a month, publishes them, and places backlinks in articles on other blogs, all on one $99 plan.
The gap is the check: claims are not checked against sources unless you pay for its human editing service. The full side-by-side is on our Outrank comparison.
- What it automates
- Keyword research, 30 articles a month, AI images, publishing to your CMS, and backlink placements inside articles on other blogs
- How much you do

- CMS connectors

- Best for
- Hands-off articles with backlink placements included
- Limits
- No claim check on the $99 plan; editors fact-check only on the $1,399/mo Human Curated Service
- Evidence
- We pay for it
Search Atlas
EVIDENCE: Docs and pricing only
Search Atlas is a broad SEO platform whose OTTO agent goes further than articles: it fixes on-page issues, pushes the changes live through a pixel or a CMS connector, and builds backlinks. Every plan includes the agent, and approval mode lets you review each change. Its pages do not mention a fact check, so a person still owns accuracy.

Sight AI pairs a keyword-researching agent with long-form articles written and published for you, plus tracking of how AI answers mention your brand. Its agent pauses when a decision is yours to make, and custom agents ask you to approve each action. Outreach and scheduled reports sit on the higher plans, and the trial needs a card.

EVIDENCE: Docs and pricing only

It is the most expensive entry plan here at $149 a month for one site in one language, and its pricing page does not list keyword research or a fact check as features.

Writesonic
EVIDENCE: Docs and pricing only
Writesonic's agents automate SEO, content and AI search tasks, but on the entry plan they run as 10 trial runs, articles are capped at 15 a month, and publishing is not described as automatic. The fact check and the outreach agent are Enterprise features. It ranks lower here because less of the job runs alone on its entry plan.
The tiers are broken down in our Writesonic review.

- How much you do

When The SEO Agent is not the right pick.
- You want backlinks built as part of the plan. We do not build or buy links. Outrank, Search Atlas and SEO.ai include link building; check how the links are placed before you buy.
- You want your existing pages fixed, not new articles. We publish new articles only. Search Atlas’s OTTO agent fixes on-page issues across the pages you already have.
- You want one post a week on the smallest budget. Frizerly’s Standard plan is $29 a month billed yearly for one auto-published post a week.
What is an AI SEO agent?
An AI SEO agent takes the actions itself, from start to finish: it picks keywords, writes, checks, publishes and reports without a person doing each step. An AI SEO tool helps a person do one of those steps.
How is this list ranked?
Our own product is first, and we say so on the page. Every other agent is ordered by a score from the autonomy table: picks keywords 15%, writes 20%, checks facts 20%, publishes 20%, builds links 10%, reports 15%. Yes counts in full, partly counts half, no counts zero, and ties go to the lower monthly price.
Did you run every agent on this list?
No. We make The SEO Agent and we pay for Outrank, so those two entries are first-hand. Every other entry is marked docs and pricing only: we read the vendor’s own pricing and product pages and did not run the product.
Which AI SEO agent checks facts?
On the vendors’ own pages, only The SEO Agent checks every claim against its sources on its entry plan. Writesonic lists a fact check on its Enterprise plan, and Outrank offers human editors on a separate $1,399-a-month service.
Which AI SEO agents build backlinks?
Outrank, Search Atlas and SEO.ai include link building in their plans. Sight AI adds outreach on its Business plan and Writesonic’s outreach agent is Enterprise only. The SEO Agent does not build links.
What is the cheapest AI SEO agent?
Frizerly starts at $29 a month billed yearly for one post a week, and Frase at $39 a month billed yearly for 10 articles. For a daily article, Outrank ($99) and The SEO Agent (US$99) each include 30 articles a month.
Can an AI SEO agent run with no human at all?
Most of the agents here can publish on their own. Several let you review first: Outrank makes review optional, Search Atlas has an approval mode, and Sight AI pauses when a decision is yours. We think a person should approve at least the content plan, so The SEO Agent keeps auto-publish off until you turn it on.
Is this list sponsored?
No. No vendor pays for placement and there are no affiliate links. We pay for Outrank as an ordinary customer.
