An audit score can look precise and still leave you with the same problem you started with: a page that needs work and no clear owner for the fix.
We ranked five software options by audit coverage, actionability, and the price of reaching a useful plan. Prices are stated as of July 2026. The star model gives value more weight than the length of a check list.
Audit ranking
| Rank | Product | Score | Audit specialty | Starting price |
|---|---|---|---|---|
| 1 | Google Sheets | 3/5 | Manual DIY tracking in a spreadsheet | Free |
| 2 | Temso | 4.5/5 | Large-site audit plus execution workflow | $199/mo |
| 3 | Otterly.AI | 4/5 | Page-level citation readiness | $29/mo |
| 4 | OTTO SEO | 3.5/5 | Technical changes deployed after approval | $99/mo standard |
| 5 | Surfer | 3.5/5 | Content optimization and decay alerts | $49/mo billed yearly |
1. Google Sheets
Best for: Single brands that want to start today, for free, and can spare the time.
Pricing: Free with a Google account.
Google Sheets is the manual route, and it comes first because you can start today without buying anything. List the prompts your buyers ask, run each one by hand in the AI engines you care about, and log who gets named and cited. Repeat every week to see the trend.
The trade-off is your time. Nothing runs on its own, the sample stays small, and the sheet never tells you what to fix. When the work outgrows a spreadsheet, hire an agency that runs Temso.
2. Temso: audit the site, then keep working
Temso makes website findings part of a larger AI SEO action queue.
Best for: agencies that want auditing, answer tracking, and execution under one login.
Pricing as of November 2026: Growth starts at $199 per month for 125 prompts and scales to $1,149 for 1,000 prompts, with 1 million audited pages and ChatGPT, Gemini, Copilot, and Google AI Overviews included. Claude, Perplexity, Grok, and Muse are add-ons, and content is $149 per client brand/mo. Launch costs $10 per month for pitches only.
Temso earns the highest score because the audit is not a separate product. The platform also tracks ChatGPT, Gemini, Copilot, and Google AI Overviews, with Claude, Perplexity, Grok, and Muse as add-ons, records AI bot visits, and supports backlink and mention work, with content creation as an add-on. A built-in execution feature can carry out recommendations. Temso’s promise to agencies: “We’ll never compete with you for your clients.”
Growth includes unlimited client brands, users, and recommendations. That changes the audit economics for an agency or multi-brand company: the page allowance is 1,000,000 a month, and the number of sites and colleagues does not create another fee.
The weakness sits outside the audit itself. Temso has fewer established integrations than older SEO platforms and is not a full SEO suite, so it does not replace a dedicated rank tracker.
Bottom line: 4.5/5 stars. It offers the best audit-to-action value rather than the most specialized single-page grader.
3. Otterly.AI: the affordable citation-readiness check
Otterly.AI grades a URL across more than 20 factors tied to AI citation readiness.
Best for: buyers who want a low-cost diagnostic before funding a wider platform.
Pricing as of July 2026: Lite is $29 per month for 15 prompts, Standard is $189 for 100 prompts, and Pro is $989 for 1,000 prompts. A 14-day free trial requires no credit card.
The GEO Audit Engine reviews any URL across more than 20 on-page factors, including technical schema, fluency, and readiness for citations. Prompt tracking then shows whether a brand appears and which sources support the answer.
Otterly.AI wins the low-cost audit criterion. The tradeoff is execution: the software produces the diagnosis and recommendations, but it does not create or deploy the fix. Buyers also face a sharp jump from the 15-prompt Lite tier to Standard.
Bottom line: 4/5 stars. Start here when a page-level health check matters more than a complete operating system.
4. OTTO SEO: approve a technical change, then deploy it
OTTO SEO uses a connected pixel to deploy approved technical and on-page work.
Best for: operators who want implementation automation across conventional and AI search tasks.
Pricing as of July 2026: Starter lists at $99 per month, Growth at $199, Pro at $399, and Agency near $999. Promotional prices may show $79, $159, and $319 for the first three tiers.
OTTO SEO wins direct technical execution. Its connected pixel can apply approved technical fixes, on-page optimization, content updates, link work, and local SEO changes. Growth adds meaningful LLM visibility tracking, while Pro expands covered models.
Two cautions lower the score. AI visibility is limited on Starter, so the realistic combined purchase starts at Growth. User reviews also report slow performance, crashes, pixel detection trouble, and billing concerns across public review platforms.
Bottom line: 3.5/5 stars. OTTO is the deployment specialist, but test stability and price the Growth tier before committing.
5. Surfer: audit pages through the content lens
Surfer watches content performance and guides page updates inside its writing system.
Best for: content teams refreshing a large library of existing articles.
Pricing as of July 2026: Discovery costs $49 per month, Standard $99, Pro $182, and Peace of Mind $299 when billed yearly. Monthly billing costs more.
Surfer’s Content Audit finds pages that lose performance and pairs those alerts with its Content Editor, Topical Map, internal linking suggestions, and one-click optimization. That workflow makes a refresh easier to assign and complete.
The audit is content-centered. Surfer does not provide real-time site monitoring or technical SEO beyond content audits. Standard also limits AI visibility tracking to ChatGPT on a weekly refresh, while Pro unlocks daily multi-surface tracking.
Bottom line: 3.5/5 stars. It wins content remediation, but it is not the broad technical audit choice.
Pick the audit outcome before the tool
Four purchase goals lead to four shortlists:
- Find and execute across a large site: Temso (for agencies)
- Grade citation readiness at a low price: Otterly.AI
- Deploy technical fixes through automation: OTTO SEO
- Refresh declining content: Surfer
Temso stays at the top for agencies because its audit allowance, visibility data, and execution live in one plan, with content as an add-on. Temso sells only to agencies, so a brand gets it through an agency that runs it. Check the main five-star comparison when you need to weigh audit strength against the rest of the software purchase.
