How Computo ensures Google Scholar indexing

Computo is indexed by Google Scholar, which means all published articles are discoverable through scholarly search. This page explains how we achieve this and what you can do to verify your article’s presence.

Technical implementation

Highwire Press meta tags

Google Scholar relies on machine-readable metadata to identify and index scholarly articles. The preferred format is the Highwire Press citation_* family of HTML meta tags. At minimum, Google Scholar requires three fields:

  1. citation_title – the exact title of the paper
  2. citation_author – the full name of at least the first author (one tag per author)
  3. citation_publication_date or citation_year – the publication date

Computo articles also include the following recommended tags for richer indexing:

  • citation_journal_title – “Computo”
  • citation_issn – “2824-7795”
  • citation_pdf_url – link to the article PDF
  • citation_abstract_html_url – link to the article landing page
  • citation_doi – the article DOI

The google-scholar flag

All Computo article repositories include google-scholar: true in their _quarto.yml configuration. When this flag is set, the Computo Quarto extension automatically generates the complete set of Highwire Press meta tags from the article’s frontmatter and citation: block. This happens at render time – no manual intervention is needed.

Here is what the configuration looks like in a published article’s _quarto.yml:

google-scholar: true
citation:
  title: "Article Title"
  author:
    - id: author1
      name: "Author Name"
      affiliation: "Institution"
  date: 2024-01-01
  doi: "10.57750/xxxxx"
  journal: "Computo"
  publisher: "French Statistical Society"
  ISSN: "2824-7795"
  url: "https://computo-journal.org/article-slug/"
  pdf: "article-slug.pdf"
  abstract: "..."

From this, Quarto generates HTML meta tags like:

<meta name="citation_title" content="Article Title">
<meta name="citation_author" content="Author Name">
<meta name="citation_publication_date" content="2024/01/01">
<meta name="citation_journal_title" content="Computo">
<meta name="citation_issn" content="2824-7795">
<meta name="citation_pdf_url" content="https://computo-journal.org/article-slug/article-slug.pdf">
<meta name="citation_doi" content="10.57750/xxxxx">

Additional discoverability features

Beyond meta tags, Computo articles benefit from several features that help Google Scholar’s crawlers:

  • Sitemap: Quarto auto-generates a sitemap.xml (thanks to site-url being configured in the main site’s _quarto.yml), which helps search engines discover all article URLs.
  • Open access: All articles are freely accessible without login walls or paywalls, meeting Google Scholar’s requirement for crawlable full text.
  • Stable URLs: Each article has a permanent URL on computo-journal.org and a DOI, ensuring persistent access.
  • Abstract visibility: The full author-written abstract is clearly visible on each article’s landing page.
  • PDF availability: Each article includes a downloadable PDF linked via citation_pdf_url.

Verifying indexing

Check if your article is indexed

To verify that a Computo article appears in Google Scholar:

  1. Go to Google Scholar
  2. Search for the article title in quotes, e.g. "A Python Package for Sampling from Copulae: Clayton"
  3. Alternatively, search by source: source:"Computo" or site:computo-journal.org

Check meta tags on an article page

To verify the meta tags are correctly generated on any published article:

  1. Open the article page in a browser
  2. Right-click and select “View Page Source” (or press Ctrl+U / Cmd+Option+U)
  3. Search for citation_ in the HTML source
  4. Verify that citation_title, citation_author, and citation_publication_date are present

Google Rich Results Test

You can also use Google’s Rich Results Test to check how Google sees a given article URL. Enter the article URL and review the detected structured data.

Google Scholar inclusion guidelines

For the full official documentation, see Google Scholar’s Inclusion Guidelines for Webmasters. Key requirements relevant to Computo:

  • Articles must be in HTML or PDF format with searchable text
  • Each article must be on a separate URL with a clearly visible abstract
  • Bibliographic data must be provided as HTML <meta> tags
  • The title tag must contain the paper title (not the journal name)
  • The author tag must contain only the actual authors
  • At least the title, one author, and the publication year must be provided

Observations

  • Coverage: Only ~5 out of 25 published articles (20%) are indexed in Google Scholar with computo-journal.org URLs.
  • Older articles more likely indexed: Articles from 2023–2024 have had more time to be crawled.
  • The 2026 article is not yet indexed: This is expected given the short time since publication.
  • Some articles indexed via other sources: The clayton paper is indexed via its arXiv version, not from the Computo landing page.
  • Google Scholar crawling is slow: It can take months for new content to appear.

Understanding URL selection by Google Scholar

ImportantKey finding: Most articles ARE indexed, but under different URLs

Our investigation (July 2026) revealed that articles not found under computo-journal.org URLs are often already indexed in Google Scholar under preprint server URLs (arXiv, HAL, OpenReview, etc.).

Why does this happen?

  1. Authors post preprints early: Many authors deposit preprints on arXiv, HAL, or submit to conferences (OpenReview) before or during journal review.
  2. Google Scholar discovers preprints first: Google Scholar crawls preprint servers regularly and indexes papers when first discovered.
  3. First URL wins: Google Scholar typically associates the metadata with the first URL it finds, which is usually the preprint.
  4. Merging is not automatic: Even after journal publication, Google Scholar may not automatically merge the preprint and journal versions.

What authors can do

If you want your Computo article to appear under the journal URL in Google Scholar:

  1. Update your preprint record: Add the journal DOI and a link to the published version on your preprint (arXiv, HAL, etc.).
  2. Use the published version flag: On arXiv, use the “Journal ref” field when updating your submission.
  3. Suggest a correction to Google Scholar: Use Google Scholar’s suggestion form to request merging versions.
  4. Cite the journal version: When citing your own work, use the computo-journal.org URL and DOI.

Recommendations

  1. Be patient: Google Scholar typically takes 2–6 months to index new scholarly content.
  2. Submit to Google Scholar directly: Authors can suggest their article for inclusion via Google Scholar’s suggestion form.
  3. Ensure cross-linking: Articles should be cited by other indexed papers to improve discovery.
  4. Consider registering with CrossRef: DOIs registered with CrossRef improve metadata propagation to scholarly databases.
  5. Update preprint records: If you have a preprint, update it with the journal DOI and published URL.

Troubleshooting

If an article is not appearing in Google Scholar despite being published:

  1. Check for preprint versions: Search Google Scholar for the article title — it may be indexed under a preprint URL (arXiv, HAL, OpenReview) instead of computo-journal.org.
  2. Wait: Google Scholar’s crawlers may take several weeks to index new content
  3. Verify meta tags: Check the HTML source of the article page for citation_* tags
  4. Check robots.txt: Ensure computo-journal.org/robots.txt does not block the article path
  5. Verify PDF accessibility: The PDF must be publicly accessible without authentication
