SEO Best Practices for Academic Journals

Publish HTML Versions of Articles (Not Just PDFs)

Since the digital era began, content creators have used PDFs (Portable Document Format) to share books, articles, and other materials online. PDFs, introduced by Adobe Systems in the early 1990s, maintain graphic integrity, making them ideal for printing, storing on e-readers, and compressing.

However, PDFs have a significant limitation when it comes to SEO. They are not as effective for crawler-based search engines like Google and Google Scholar. To improve visibility, it is advisable to publish HTML versions of articles alongside PDFs.

Google and PDFs

Contrary to some beliefs, Google does index PDFs, as confirmed in 2011. However, PDFs typically rank lower in search results than HTML pages. This is because PDFs often lack structured data and metadata that crawlers use to organize content. Additionally, PDFs are not easily navigable and are less mobile-friendly.

If publishing only in PDF is necessary, ensure the text is accessible to crawlers by making it selectable (copy-pasteable). Also, host each PDF on an HTML page enriched with metadata and mobile-friendly design.

Ensure Your Journal Website and Article Pages Are Mobile-Friendly

Publishing mobile-friendly content is crucial for high search engine rankings. Since 2018, Google has prioritized mobile-first indexing, meaning mobile-friendly pages rank higher.

To ensure content is mobile-friendly, use responsive web design, allowing HTML pages to adjust to various screen sizes. If you only publish PDFs, host them on individual mobile-friendly HTML pages with in-browser PDF viewers.

Check your site’s mobile-friendliness using Google’s Mobile-Friendly Test tool. If necessary, update your site to be mobile-friendly, either by upgrading your CMS template or revising the code for custom-built sites.

Add Rich Machine-Readable Metadata to All Articles

For articles to appear in search results, they need to be accessible to both humans and machines. Search engines rely on metadata to understand article content and determine search result rankings. Metadata should be available in HTML meta tags and XML files formatted in the JATS standard for scholarly indexes.

Key metadata fields include:

  • Journal publisher
  • Journal issue details (publication date, volume/issue number)
  • Journal title
  • ISSN
  • Article title
  • Author names
  • Keywords
  • Copyright license
  • Persistent Identifiers (DOI, ORCID iD, ROR ID)

Link Article Citations to Their Sources

Search engines consider embedded links to assess content relevance and trustworthiness. Academic journals should link references and citations to their sources, preferably using persistent links like DOIs. This is easier with HTML but also possible with PDFs.

Add Published Articles to a Sitemap

Adding articles to a sitemap increases the chances of being indexed by search engines. A sitemap is a machine-readable list of important web pages, typically in XML format. Sitemaps help search engines find new and updated content quickly.

Journals can create sitemaps by coding, using generator tools, or utilizing hosting platforms that automatically include articles in sitemaps.

Publish on a Rolling Basis for Fresh Content

Frequent publishing improves the chances of being indexed by search engines. Journals should consider a rolling publishing model, releasing content as it becomes ready rather than waiting to compile issues. This model, used by journals like Survey Practice, the flagship of the American Association for Public Opinion Research, helps maintain a steady flow of fresh content for search engine crawlers.

SEO Best Practices for Researchers Writing Articles

Focus on High-Quality, Readable Content

Your primary goal when writing research articles should be to ensure high-quality content, which aligns with search engine preferences. Invitation-based academic indexes like Google Scholar only accept content from reputable sources, and mainstream search engines like Google evaluate content quality through signals such as originality, comprehensiveness, insightfulness, and credibility. Google’s sophisticated algorithms prioritize “helpful, reliable, people-first content.” Therefore, producing well-researched and helpful articles will naturally meet these criteria.

Readability also affects search rankings. Structure your article for easy scanning with clear headings and subheadings. Use bulleted lists, tables, and graphics to enhance readability and help readers quickly grasp key points.

Include Relevant Keywords in Text and Metadata

To improve search engine ranking, incorporate relevant keywords in both the article’s body text and metadata. As an expert in your field, you’ll naturally include essential keywords. For instance, an article on AI might frequently mention “Artificial Intelligence (AI)” and “Machine Learning (ML),” along with related terms like ChatGPT and speech recognition.

Creating a list of keywords before writing can help keep these terms in focus. Consider what search terms you’d use to find your article topic and test them in search engines and academic databases. Keywords should be prominently featured in your article title and abstract, as some scholarly search engines index only these sections.

For article-level metadata, start by listing your keywords and check for any missing terms before submission. If keyword suggestions are uncertain, don’t hesitate to ask the journal.

Make Your Article Title Search-Engine Friendly

Article titles are crucial for SEO. Include primary keywords and clearly communicate the article’s subject and the problem it addresses. A concise and compelling title like “A Critical Analysis of AI in Academic Writing” is more effective than a vague or pithy title. The title should convey the article’s value and encourage clicks without exaggerating its scope or findings, as Google discourages hyperbole.

Build Up Backlinks to Your Articles

Backlinks are a critical factor for search engine ranking. They signal content quality and relevance, especially when from trusted and authoritative websites. Researchers should seek opportunities to gain backlinks by contributing to relevant publications or participating in interviews that link back to their work.

In academia, citations are powerful backlinks. Search engines like Google Scholar and databases like Web of Science consider citation counts in search results. Google Scholar uses citations to identify new content for indexing and only accepts content from trusted academic sources. Learn more about how Google Scholar works here.

Share Your Articles on Social Media

Sharing your research on social media platforms like LinkedIn, Twitter, Mastodon, Facebook, and ResearchGate can significantly improve SEO. This increases visibility, attracts new readers, and can lead to more backlinks as others reference and link to your work. An example is Lajos (Lou) Balogh, Editor-in-Chief of Precision Nanomedicine, who shares his editorials on Twitter, expanding their reach and impact.

By following these SEO best practices, researchers can enhance the discoverability and impact of their articles.


Mastering SEO for academic articles is essential for increasing visibility, readership, and impact. By focusing on high-quality, readable content, optimizing titles and metadata, ensuring mobile-friendliness, and building backlinks, researchers and journals can significantly improve their search engine rankings. Additionally, publishing HTML versions of articles, adding rich machine-readable metadata, and actively sharing research on social media platforms further enhance discoverability. By integrating these best practices into your publishing strategy, you can ensure that your research reaches a broader audience and achieves greater academic influence. Embrace these SEO strategies to maximize the potential of your scholarly work in the digital age.
