What is SEO Audit Studio for?
SEO (search engine optimisation) is everything that helps Google find, understand and rank the pages of your site. Many sites lose visitors because of small invisible problems: a missing title, an error page, a site that's too slow, a setting that blocks Google…
You enter your site's address and our server actually crawls it, page after page, the way Google does. It checks 60+ points, gives a score out of 100 and ranks the issues by severity, each with a simple explanation and how to fix it. Nothing to install, and your site isn't changed: the tool only reads it.
Who is it for?

Beginners
Every point is explained simply, without unnecessary jargon.
The steps, one by one
Enter your site's address
Type the address in the "Start a new SEO audit" box (for example mysite.com). Choose the number of pages to crawl
(10 in the discovery version, up to 250 in Pro) and the depth: 2 levels = the home page, the pages linked from the home page, and the pages linked from those.
Describe your site (optional but useful)
In section 1, enter the site name, your industry and your goals. In section 4, add your keywords (the words your customers type into Google) and the address of 1 to 5 competitors. This information feeds the keyword analysis, the comparison and the AI.
Choose the checks
Section 3 lets you turn each family of checks on or off: technical, content, performance, mobile, links, structured data, security, international (multilingual sites). By default, everything useful for most sites is ticked. In Pro, tick "Measure Core Web Vitals" to have Google measure your home page's real speed.
Click "🔍 Analyse"
The progress bar shows the pages crawled. Allow a few seconds to 2-3 minutes depending on the number of pages and your site's speed.
The tool also reads robots.txt and the sitemap, and checks redirects, security headers, compression and file caching.
Fix things, starting with red
The "Overview" tab lists the 5 points to fix first. The "⚠️ Issues" tab details each point, with the pages concerned and the steps to take. After your fixes, run the audit again to watch your score go up.
robots.txt or not, include subdomains, identify as Googlebot or space out requests if your hosting is fragile.The score out of 100
Each category (technical, content, performance, mobile, links) gets a score: the more serious an issue is and the more pages it affects, the more it lowers the score. The overall score is the average of the categories. Issues are ranked in 4 levels:
- 🔴 Critical: blocks or heavily penalises your rankings (insecure site, 5xx error pages, page set to "noindex" by mistake…).
- 🟠 High: significant impact (missing or duplicate title, no sitemap, slow pages…).
- 🔵 Medium and ⚪ Low: useful improvements, to do next.
Above 75, your site is in good health; between 45 and 75, there are worthwhile fixes to make; below 45, start with the critical points.
The tabs
| Tab | What it's for |

| ⚠️ Issues | Every point, filterable by severity, with the pages concerned and how to fix it |
| 🔧 Technical | HTTPS, robots.txt, sitemap, canonical, noindex, redirects, errors, structured data, security |
| 📝 Content | Titles, descriptions, H1, text length, images, internal links, and the list of crawled pages |
| ⚡ Performance | Response time, page weight, compression, caching, CSS/JS, and Core Web Vitals measured by Google (Pro) |
| 📱 Mobile | Viewport tag and phone-friendly display |
| 🔗 Backlinks | The links on your site: internal linking, anchors, broken outbound links |
| 🔑 Keywords | Where your keywords appear (titles, descriptions, H1, home page text, density) |
| 🎯 Competitors (Pro) | Each competitor's home page scored on the same criteria as yours |
| ✨ AI (Pro) | Analysis, prioritisation, title rewrites, recommendations, roadmap, chat |
| 📤 Exports | All the reports to download (watermarked in the discovery version; data with Pro) |
AI (optional) (Pro)
- 🔍 Analyse the audit: the 3 urgent points, the quick wins, what can wait.
- 🎯 Prioritise: each issue ranked by impact and effort required.
- 📝 Rewrite titles: 2 suggestions for each page whose title is missing, too short or too long.
- 💡 10 recommendations, 🎯 competitive analysis and 🗺 30/60/90-day roadmap.
- Chat: ask your questions; the AI already knows your audit results.
- Open the ✨ AI tab and choose your provider: Agnes, OpenAI (ChatGPT), Anthropic (Claude), Mistral, Groq, Google Gemini, DeepSeek, OpenRouter or any OpenAI-compatible service.
- Create an API key with that provider (the link appears under the list; several offer free access, such as Agnes, Groq or Gemini).
- Paste your key, click "🔌 Test connection" then "💾 Save".
Exports
Reports (PDF, HTML, Markdown, client report, action plan, ZIP) are open to everyone; in the discovery version they carry a “Discovery version · Made with Yok-Kod” watermark (at the end of the document, at the bottom of each printed page and as the last line of Markdown files), even in white label, and the ZIP leaves out the data files. Pro removes the watermark. Data exports (CSV, Google Sheets, Screaming Frog, JSON) are for Pro.
- PDF report and HTML report: the full report, to print or send.
- Client report: a short summary, and action plan: the list of tasks to tick off, from most to least urgent.
- Markdown (the report as text), CSV and Google Sheets (Pro): to rework the results elsewhere. Screaming Frog (Pro): the page list in that software's format.
- Full ZIP: all the files at once. In the Exports tab, you can include the addresses of the pages concerned, the passed checks and the AI analysis, or remove the Yok-Kod credit (white label).

Common issues
- What does "Domain not found" or "Unreachable" mean?
- Check the spelling of the address and that your site is online. Local sites (localhost) or sites on a private network can't be audited.
- Why were only a few pages crawled?
- The tool follows your site's links: pages that aren't linked from anywhere aren't found (they show up as "orphans" if they're in your sitemap). Menus built only in JavaScript aren't always visible. Also increase the depth and the number of pages.
- Why does my site block the tool (403 or 429 error)?
- Some firewalls (Cloudflare, Wordfence…) block robots. Choose a 500 ms or 1 s delay in "Delay between requests", or temporarily allow the "YokKod-SEOAudit" robot.
- Why don't the Core Web Vitals show?
- They're measured by Google PageSpeed Insights, which can be overloaded or refuse certain pages. Run the audit again a few minutes later. The "INP" metric only exists for sites with enough visitors.
- Why does the AI say "invalid key"?
- Check that the selected provider matches your key, then test it again. Free keys are limited to a few requests per minute.
- Why can't I find my audit any more?
- Make sure you're using the same computer, the same browser and the same account.
