Question 1

What is Duelly?

Accepted Answer

Duelly is a search intelligence platform that audits your website across three pillars: SEO (Search Engine Optimization), AEO (Answer Engine Optimization), and GEO (Generative Engine Optimization). We help you optimize for traditional search, featured snippets, and AI-generated responses.

Question 2

What's the difference between Free and Pro audits?

Accepted Answer

Free Audit runs a comprehensive rule-based analysis checking 50+ technical and content signals — no AI involved. Pro Audit adds AI-powered analysis using Gemini to generate specific fix instructions, deeper content evaluation, and actionable recommendations tailored to your site type.

Question 3

What does Deep Scan do?

Accepted Answer

Deep Scan crawls multiple pages across your site (up to 50 pages depending on your plan) and provides a site-wide analysis. It identifies patterns, inconsistencies, and opportunities across your entire domain rather than just a single page.

Question 4

What is Competitive Intel?

Accepted Answer

Competitive Intel lets you compare your page against a competitor's page side-by-side. It identifies stolen opportunities, strategic gaps, and provides counter-strategies to help you outperform the competition across all three pillars.

Question 5

How are scores calculated?

Accepted Answer

Each pillar (SEO, AEO, GEO) is scored out of 100 using a component-based system. Scores are weighted based on your detected site type (e-commerce, blog, SaaS, etc.) to ensure relevant factors matter most. Grade boundaries: A (90-100), B (80-89), C (70-79), D (60-69), F (<60).

Question 6

Why do my scores differ between audit types?

Accepted Answer

Free audits use rule-based analysis only, while Pro audits incorporate AI evaluation for deeper content and quality assessment. The underlying scoring components are the same, but Pro audits can detect nuances that rule-based checks miss.

Question 7

Why did my score change slightly between scans?

Accepted Answer

Pro and Deep Scan audits use AI to evaluate your content the same way answer engines and generative search actually read your site. Just like ChatGPT or Perplexity re-evaluates content every time it encounters it, our AI analysis produces a fresh assessment each scan. Minor variations of ±3 points are normal and reflect how AI perception genuinely works. Your technical checks (meta tags, schema, HTTPS, H1s) are always 100% consistent — it's only the AI quality signals that can shift slightly. This isn't a flaw — it's an honest representation of how your content will be judged in the real world.

Question 8

What are site types and why do they matter?

Accepted Answer

Duelly automatically detects your site type (e-commerce, blog, portfolio, SaaS, news, local business, etc.) and adjusts scoring weights accordingly. An e-commerce site is evaluated differently than a blog because different signals matter for each. This ensures fair, relevant scoring.

Question 9

Where is my scan data stored?

Accepted Answer

All scan history and results are stored locally in your browser's localStorage. Nothing is sent to or stored on our servers beyond the initial analysis. If you clear your browser data or switch devices, your history will be lost. Use the Export feature on the Dashboard to back up your data.

Question 10

Can I export my scan history?

Accepted Answer

Yes. On the Dashboard, you'll find Export and Import buttons next to Recent Scans. Export downloads a JSON file with all your scan history and full results. You can import this file on another device or after clearing your browser data.

Question 11

What data do you collect during a scan?

Accepted Answer

We fetch the publicly available HTML of the URL you provide, analyze it, and return the results. For Pro and Deep scans, the page content is sent to Google's Gemini API for AI analysis. We don't store your page content after analysis is complete.

Question 12

What are the plan limits?

Accepted Answer

Pro ($20): 20 audits, 10 deep crawls (50 pages each), 10 competitive intel scans. Pro Plus ($50): 60 audits, 60 deep crawls (50 pages each), 25 competitive intel scans. Agency ($100): 150 audits, 150 deep crawls (50 pages each), 50 competitive intel scans. Credits are one-time purchases — buy more when you need them. Free audits don't count against your credits.

Question 13

Do free audits count against my plan?

Accepted Answer

No. Free audits are unlimited and don't use any AI credits. Only Pro Audits, Deep Scans, and Competitive Intel analyses count against your monthly quota.

Question 14

My scan is stuck or failed — what should I do?

Accepted Answer

First, check the API status indicator in the top header bar. If it shows 'error', our analysis service may be temporarily unavailable. Try again in a few minutes. If the URL is behind authentication or a firewall, we won't be able to access it. Make sure the URL is publicly accessible.

Question 15

Why does my site score lower than expected?

Accepted Answer

Common reasons: missing meta descriptions, no structured data (Schema.org), thin content, missing alt text on images, no FAQ or Q&A content for AEO, and lack of expertise signals (author info, citations) for GEO. Check the detailed breakdown in your audit results for specific recommendations.

Question 16

The page looks different than what was analyzed

Accepted Answer

Duelly fetches the server-rendered HTML of your page. If your site relies heavily on client-side JavaScript rendering, some content may not be visible to our crawler. This is also how search engines see your page — if we can't see it, neither can Google.
