SEO 도구
페이지의 HTML에서 제목, 설명, Open Graph 태그, 키워드 밀도를 확인하고 검색 결과 미리보기를 제공합니다. 분석은 로컬에서 실행됩니다.
사용 방법
Paste a page's HTML — or fetch it from a URL — and press Analyze. Fourteen mechanical checks run locally: title and meta description length, H1 count, missing image alt attributes, Open Graph tags, canonical, JSON-LD and more, plus a search-result preview and, if you enter a keyword, its occurrence count and density. Enter the page URL as well so relative links can be counted as internal. All analysis runs in your browser.
참고 사항
URL fetching uses the browser's fetch, so sites that do not allow cross-origin reads (CORS) cannot be fetched — paste the page source instead. The result is a checklist, not a ranking score: the length guidelines and thresholds follow common practice, not any search engine's official criteria, and passing every check does not guarantee any position.
자주 묻는 질문
Why can't some URLs be fetched?
Because of the browser's CORS rules: unless the target site allows cross-origin reads with Access-Control-Allow-Origin, the browser will not hand the HTML to this page. This tool runs entirely in the browser and cannot bypass that.
What keyword density should I aim for?
There is no official ideal value. This tool reports the count and density as facts and does not recommend a target; unnatural stuffing can hurt rather than help.
