需要改善的項目 12 項
| 重要度 | 類別 | 項目 | 內容 |
|---|---|---|---|
| 需要處理 | Link Structure | Internal Links | There are no internal links. This cuts off both user navigation and crawl paths within the site. |
| 需要處理 | Meta Information | Meta Description | There is no meta description. It is recommended since it becomes the description text shown in search results. |
| 尚有改善空間 | Page Quality | Body Text Length | The body text is a bit thin. Expanding on the topic with more detail tends to be evaluated more favorably. |
| 尚有改善空間 | Server Settings | HTML Size | The HTML is fairly large. Consider trimming unnecessary markup or inline code. |
| 尚有改善空間 | Server Settings | Compression | gzip / brotli compression is not enabled. Turning it on can significantly reduce transfer size. |
| 尚有改善空間 | Meta Information | Canonical | No canonical tag is set. If duplicate URLs exist (with/without www, different parameters, etc.), setting one is recommended. |
| 尚有改善空間 | Meta Information | Language Attribute (lang) | Specify a language, e.g. <html lang="en">. |
| 尚有改善空間 | Meta Information | Character Encoding Declaration | Add <meta charset="UTF-8"> near the top of the head section. |
| 尚有改善空間 | Meta Information | Favicon | No favicon is set, reducing visibility in browser tabs and search results. |
| 尚有改善空間 | Meta Information | OGP (Social Sharing) | OGP is not set up, so no title or image will appear when this page is shared on social media. |
| 尚有改善空間 | Page Quality | Text-to-HTML Ratio | The body text is small relative to the HTML — most of the page is markup, styling, or scripts. |
| 尚有改善空間 | Page Quality | Structured Data | Adding schema.org structured data can improve how this page appears in search results. |
