Internal links in WordPress are clickable links that connect one piece of content on your site to another piece on the same domain. When you link from a blog post to your services page, or from one article to a related guide, that's an internal link. WordPress makes adding them straightforward through the built-in link button in the block editor or classic editor. From an SEO perspective, internal links serve two critical functions. First, they help search engines discover and crawl your content. When Googlebot lands on your homepage, it follows internal links to find your other pages. Without proper internal linking, pages can end up orphaned and invisible to search engines. Second, internal links distribute link equity (PageRank) throughout your site. When you link from a high-authority page to a newer or weaker page, you're passing some ranking power to help that page perform better. In WordPress specifically, you have several ways to create internal links: - Manual links added through the editor when writing posts - Navigation menus configured under Appearance > Menus - Widget links in sidebars or footers - Related post plugins that auto-generate contextual links - Category and tag archives that automatically link to tagged content The key is using descriptive anchor text that tells users and search engines what the linked page is about. Avoid generic "click here" or "read more" anchors. If you're linking to a page about local SEO, use anchor text like "Ottawa local SEO strategies" rather than vague phrases. At Ottawa SEO Inc., we typically aim for 2-5 contextual internal links per blog post, linking to pillar content, service pages, or related articles. We also run quarterly audits across our 500+ domain portfolio to identify orphaned pages and fix broken internal links. WordPress plugins like Yoast or Rank Math can help track internal linking, but manual strategic linking based on topic clusters usually outperforms automated approaches for competitive keywords.
