• Format Author Names Consistently: Use the same format (e.g., first name, last name) across all publications and platforms. Consider using ORCID identifiers for authors.
• Use High-Quality PDFs: Create searchable PDFs with full text and avoid image-based PDFs. Embed metadata within the PDF document properties.
• Optimize HTML Pages: Make sure the HTML pages for each publication are well-structured with clear titles, headings, and body content. Include the full text of the research and relevant keywords naturally throughout the text.
• Link to Related Publications: Use internal links to connect related research on your website. This helps Google Scholar understand the context and subject matter of your publications.
