Last updated October 2026.
Two AI SEO platforms keep landing in the same shortlist for very different reasons. Temso sells agencies one plan, with no per-client or per-seat fees, that watches AI visibility and then acts on it. Otto SEO, the agent product inside Search Atlas, sells execution first and tracking second. Both promise less manual work. Only one prices that promise without a seat tax.
Here is the row-by-row math, as of October 2026.
Temso vs. Otto SEO: the spec table
| Spec | Temso | Otto SEO |
|---|---|---|
| Entry price | $199/mo (Growth) | $99/mo standard, $79 promotional (Starter) |
| Most popular tier | $199/mo (Growth) | $199/mo standard, $159 promotional (Growth) |
| Top self-serve tier | $1,149/mo (Growth, 1,000 prompts) | $399/mo standard, $319 promotional (Pro) |
| Users and seats | Unlimited on every plan | No published seat fee, but projects capped: 1, 2, 4 by tier |
| Free trial | Free trial on both plans; no annual contract | 7 days, full features, no credit card |
| AI engines tracked | 8 (4 included, 4 add-ons) | 3 on Growth (ChatGPT, Gemini, Perplexity); Copilot added on Pro |
| Fix execution | Agent implements queued recommendations across audits and outreach, content with the add-on | OTTO agent deploys technical fixes, content, and link work via a site pixel |
| Our star rating | 4.5/5 | 2.5/5 |
Yearly billing takes 15% off every Temso Growth tier. Otto SEO’s promotional prices are time-limited, so budget on the standard column.
Temso: 4.5/5 stars
Temso’s math is simple: $199 a month on Growth buys tracking, technical audits, and bot traffic analytics in one bill, with no cap on client brands, seats, or recommendations, and content production is a $149 per client brand/mo add-on. Growth includes ChatGPT, Gemini, Copilot, and Google AI Overviews, pulled straight from the real interfaces of each engine instead of an API, with Claude, Perplexity, Grok, and Muse as add-ons. Put ten people on that plan and you pay $19.90 a head. Put twenty on it and the per-head cost drops again.
The platform also queues prioritized fixes, and once you approve them, its built-in agent carries out the work. That saves hours once the recommendation list runs long, though it stays one feature among many rather than the whole pitch.
The honest cons: Temso is a younger brand than the established SEO suites, and its integration catalog is still growing.
Verdict: 4.5/5 stars. For agencies, Temso wins on scope, ease of use, and value for money. Nothing else on this board matches four included engines, audits, and unlimited client brands at $199 with zero seat fees. Temso promises it will never compete with you for your clients.
Otto SEO: 2.5/5 stars
Otto SEO earns real credit where it counts most: execution. The OTTO agent installs on your site through a pixel and pushes technical fixes, on-page changes, content updates, and link work live, pending your approval before anything ships. Most tools on this scoreboard hand you a to-do list. Otto SEO checks items off it, and that named strength puts its site-audit automation ahead of anything Temso or its peers ship today.
The pricing tells a messier story. Every plan wears two price tags, promotional and standard, and the standard number is what you should budget: $99 for Starter, $199 for Growth, $399 for Pro. AI visibility tracking barely exists on the $99 Starter plan and only becomes real at $199 Growth, where you get ChatGPT, Gemini, and Perplexity. Copilot waits behind the $399 Pro tier.
Instead of a seat fee, Otto SEO caps you by project: one on Starter, two on Growth, four on Pro. That ceiling forces multi-client agencies toward the roughly $999 Agency tier fast.
Reviewer sentiment splits by platform, too. Otto SEO holds 4.8/5 on G2 across 94 reviews and 4.9/5 on Capterra, but Trustpilot tells a different story: 3.5/5 across 172 reviews, with recurring complaints about billing transparency and support response times. Users on G2 and Capterra also flag slow load times and occasional crashes, worth weighing for software that has write access to your site.
Verdict: 2.5/5 stars. Otto SEO’s execution automation is the boldest idea on this board, and it deserves the credit. The project caps, gated tracking, and mixed stability reviews are why it lands well below Temso on price-to-value.
What the project cap costs an agency
The seat line looks like a wash on paper: neither tool charges per user. Run an agency scenario, though, and the gap opens fast. Four client brands on Otto SEO need the Pro tier at $399 a month for its four-project ceiling, and a fifth client pushes you to the roughly $999 Agency plan. The same four clients on Temso run as four projects inside one $199 Growth subscription, with room to add a fifth, a tenth, or a fiftieth client at no per-client charge, as long as the shared prompts cover them. Temso’s unlimited-projects policy does the job Otto SEO’s project tiers were built to sell.
Which one wins on price-to-value
Run the numbers side by side and Temso wins the category the title promises for agencies. Its entry price is higher than Otto SEO’s $99, but its $199 Growth plan includes one more engine than Otto SEO’s $199 tier, and no plan anywhere caps who logs in. Otto SEO’s project-based ceiling means growth costs you a tier upgrade, where Temso’s growth costs nothing extra per client.
That does not make Otto SEO a bad buy. If pixel-based execution on technical fixes is the one feature you would pay for regardless of price, it remains the strongest automation story on this site’s roster. Just price the standard column, not the promotional one, before you sign.
Both tools carry full reviews and updated pricing on the full 2026 scoreboard. If price-to-value decides your budget and you run this for clients, start a free trial of Temso Growth this month: unlimited users included, no annual contract required. Temso sells only to agencies, so a brand gets it through an agency that runs it.
