Nielsen’s Heuristic | Mapped parameters (A-codes) | Explanation |

2. Match between system and the real world | A11 (navigation menu), A15 (intuitive navigation) | Structured and intuitive navigation uses familiar conventions, matching user expectations. |
3. User control and freedom | A12 (search functionality), A15 | Search and navigation help users move freely and recover from errors. |
4. Consistency and standards | A11, A13, A14, A33 | Consistent use of working links, proper hierarchy, and menu placement reflects standard web conventions. |
5. Error prevention | A14 (no broken links), A25 (security headers) | Avoiding broken links and enforcing security helps prevent user errors and vulnerabilities. |
6. Recognition rather than recall | A11, A15, A33 | Intuitive structure, headings, and clear menus reduce cognitive load. |
7. Flexibility and efficiency of use | A12, A23, A41, A42 | Search functions, optimized images, and responsive design support both novice and expert users. |
8. Aesthetic and minimalist design | A34 (color usage), A23 | Good color contrast and appropriate image sizing promote simplicity and clarity. |
9. Help users recognize, diagnose, and recover from errors | A14, A21, A22 | Working contact information and correct links enable error reporting and support. |
10. Help and documentation | A21, A22 | Clear contact options serve as help/documentation channels for the user. |
