What's inside

Five disciplines, one report.

Sentinel doesn't just run a scanner. Every audit blends five separate lenses, traditional SEO, generative-engine readiness (GEO), AI-answer engines (AEO), accessibility (ADA baseline), and California privacy compliance, into a single coherent report you can hand to a stakeholder. It is informational, not legal advice.

01 · SEO

Technical + rank layer

Full-site crawl against the Screaming Frog rule set, plus live Google + Bing rank tracking on the queries that matter for your business.

  • Title, meta, canonical, heading hierarchy audits
  • Broken links, redirect chains, sitemap-vs-crawl diff
  • Security header + robots directive checks
  • Google + Bing rank tracker for your target keywords
02 · AEO

Answer-engine visibility

How the four major LLM answer engines respond when someone asks about your industry, and whether your brand shows up.

  • 10 prompts × ChatGPT, Claude, Perplexity, Gemini
  • Real citation URLs from each answer
  • Share of voice vs. up to 3 named competitors
  • Prompt bank you can add to over time
03 · GEO

GEO-16 answer readiness

16 on-page signals AI engines use to decide what to cite, scored 0-100. Grounded in the Princeton GEO study and GEO-16 framework.

  • Semantic HTML5, heading tree, chunkability
  • JSON-LD schema completeness, visible + machine dates
  • Definitions, FAQ patterns, concrete statistics, byline
  • Authoritative outbound links, inline citations, /llms.txt
04 · ADA baseline

Accessibility, checked against WCAG 2.1 AA

Automated WCAG 2.1 AA scan with axe-core, plus the 5-point ADA baseline: the issues that come up most often in demand letters. It is a scan, not a certification, and it does not make you immune to a claim.

  • axe-core WCAG 2.1 AA (alt text, form labels, contrast, semantics)
  • Keyboard walker: Tab-order + focus-visible + focus-trap detection
  • Accessibility Statement audit (page presence + footer link + WCAG cite + contact channel)
  • Report cites 8,667 federal ADA suits in 2025 as backdrop
05 · California privacy

CCPA/CPRA + CIPA compliance

The category people most often wish they had run before a demand letter arrived. Every finding cites the statute, regulation, or AG press release behind it.

  • 11 CCR § 7011, full 12-element privacy policy audit (LLM-classified)
  • Pre-consent tracker inventory + CIPA § 631 exposure ($5k/violation flag)
  • GPC honor test + DNSMPI link presence + Reject-All parity
  • Session-replay + live-chat vendor detection (Popa v. Harriet Carter Gifts pattern)

Need ongoing monitoring?

Re-scans, drift detection and monthly re-audits are scoped to the site rather than sold off a card, because what they cost depends on how many pages change and how often you want to know. Tell us what you need and we will price it.

Everything above is a one-off report. You buy it once, you get the file, and there is nothing to cancel.

Add-ons
Remediation Markdown
Bundled in All-Category and Plan Conformance. $99 one-off with any other report.
LLM/agent-ready fix file. Drop into Claude Code, Cursor, or your coding agent and the fixes are written out so your developer can apply them.
Consent banner and receipt log
Ask when you request the report
If your Legal Shield or All-Category report flags consent, we can supply the banner and the receipt storage that fixes it, under your brand or ours. Priced with the work rather than off a card.
Frequently asked

Questions we hear often.

Do I need to be logged into Google Search Console for you to scan my site?
Nope. Sentinel scans externally, the way a search engine or a competitor would. If you do grant us Search Console read access (optional, Deluxe and Executive tiers only), we'll layer in your first-party impression + click data alongside the external view. Fine either way.
Is this a compliance certification for ADA?
No. Automated accessibility scanning, including axe-core, which is the same engine Google Lighthouse uses, catches roughly 30 to 40 percent of the WCAG 2.1 AA success criteria. Full compliance always requires a human running through the site with a keyboard and a screen reader. Sentinel is the starting point that catches the machine-detectable ~40%. We'll happily quote the human portion as a separate engagement.
What if my report is thin because my site is small?
The four scanners run regardless of site size, a five-page site gets the same rigor as a five hundred-page site. Small sites tend to score higher on technical dimensions and lower on AEO (there's simply less content for AI engines to cite). The report says exactly that when it applies, no fluff.
Can I buy an audit for a domain I don't own?
Only with permission. Our terms require that you own the domain, administer it, or have explicit written permission from the owner. Sentinel only scans publicly-accessible pages, everything a search engine or a competitor could already see.
Is there a subscription option?
No. Everything here is a one-off report: you buy it once, you get the file, and there is nothing to cancel. Ongoing monitoring, drift detection and scheduled re-audits do exist, but what they cost depends on how big your site is and how often you want it checked, so they are quoted rather than sold off a card. Tell us what you need.
What's your refund policy?
If we miss the turnaround we quoted you, you get a full refund. If we deliver on time, no refunds, but if you spot something wrong in the report, tell us and we'll re-run the affected sections for free.
