Internal links take users from one of your site’s pages to another. This accomplishes a few things: First, it helps you cement authority within a given subject area by showcasing a range of related content. Second, internal linking makes your content more accessible to search engine crawlers, allowing them to index pages on your website and display them on SERPs. In addition to boosting your SEO, internal links can keep visitors on the site longer and may lead to more customer conversions.
