Detartech Site Analyzer

Detartech Site Analyzer is a free Chrome extension built by Detartech and published on the Chrome Web Store; it checks the page in the open tab in one click for SEO, speed, AI visibility, sharing and privacy. It is designed for site owners, marketers and agencies: you see in a single report how a page looks to search engines and to AI bots. It is not a crawler. Each time it inspects only the one page in the tab whose icon you clicked. For installation and first steps, see the extension page.

What it checks

On the SEO side it inspects the length of the title and meta description, the number of H1s and the heading order, the canonical, noindex, robots.txt, the sitemap, the page language, image alt text and broken internal links. On the speed side it compares LCP, CLS, INP, TTFB and FCP against the Core Web Vitals thresholds, and it also lists page weight, third-party requests and DOM size.

The AI visibility section looks at whether the content is visible without JavaScript, at the llms.txt file, at whether robots.txt blocks seven AI bots (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot and Applebot-Extended), and at JSON-LD structured data. The sharing section shows the Open Graph and Twitter card tags, the favicon, and a preview of the Google result and of the share card. The privacy section summarizes tracking tools, cookie consent detection and security headers. A separate technology tab recognizes what the page is built on, and e-commerce platforms common in Türkiye such as ikas, IdeaSoft and T-Soft are on the list as well.

Scoring and your data

Each check ends as good, warning or problem and counts as 1, 0.5 and 0 points; some critical checks carry triple weight. The categories feed the overall score with weights of 30 for SEO, 30 for speed, 20 for AI visibility, 10 for sharing and 10 for privacy. A score of 80 or more shows in the green band and 50 or more in the amber band. The speed figures are not lab data: they come from the single load of that page in your own browser at that moment.

Analysis data is not sent to Detartech. The extension sends requests only to the site you are inspecting, uses no cookies in those requests and needs no account. For details, see the extension section of the privacy policy.

How we built it

Our aim was to show how a page looks to search engines and AI bots on one screen, without creating an account. That is why we wrote the extension with as few permissions as possible. It uses Manifest V3 and asks only for the activeTab, scripting and storage permissions; there is no separate access permission for websites. In other words, the extension touches no page whose icon you have not clicked.

The speed section relies on values read from the browser's own performance measurement interface and interprets them against the Core Web Vitals thresholds. This is one local measurement. It does not replace field data or a lab tool such as Lighthouse; it exists to show where a page stands at a quick glance.

For AI visibility we read robots.txt separately for each of the seven AI bots and evaluate rule by rule whether a bot can reach the whole page. We also compare the raw HTML of the page with the version rendered in the tab: the difference shows how much of the title, the description, the H1 and the content a bot that does not run JavaScript can see. We built the report as a starting point rather than a verdict, and next to every finding it says what we looked at.

In the privacy section we look for 11 tracking tools together with their identifiers, for a cookie consent notice (nine known platforms, general heuristics and the Google Consent Mode signal) and for five security headers. These do not give a definitive GDPR or KVKK verdict; they list the traces we see on the page and leave the judgement to you. In the broken-link check we look at no more than 40 internal links so that the report stays fast.

We did not base the scoring on a hidden formula: the weights and bands are fixed as written above, and the result of each check shows separately as good, warning or problem. That way you can follow from the checklist why a score dropped.

We took care to keep the extension small (about 104 KiB), the popup summarizes the results in seven tabs, we offer the interface in Turkish and English, and we let you open the report on its own page and save it as a PDF through the browser's print menu.

Limits: the extension works on Chrome 102 and later, its interface is only in Turkish and English, and it inspects a single page. Privacy findings are a hint, not a legal verdict.
