Automated Internal Linking with Tag-Based Content Graphs

Why Internal Links Matter Internal links distribute page authority, help Google discover content, and keep users engaged. For 80+ articles, manual linking is unsustainable. Tag-Based Link Graph Every article has tags in frontmatter. The algorithm finds related articles by tag overlap: function buildLinkMap(articles) { const linkMap = {}; for (const article of articles) { const related = articles .filter(a => a.slug !== article.slug) .map(a => ({ slug: a.slug, overlap: a.tags.filter(t => article.tags.includes(t)).length })) .filter(a => a.overlap > 0) .sort((a, b) => b.overlap - a.overlap) .slice(0, 6); linkMap[article.slug] = related; } return linkMap; } Output Format The script generates a TypeScript file with related articles that components import for rendering. Dry Run Mode Run with --dry-run to preview changes before committing. Impact After implementing automated internal linking: Average internal links per article: 1.2 to 5.4 Pages with zero internal links: 23
