Internal Linking

What is Internal Linking and Why is it Important for SEO?

Internal linking is hyperlinks that are given from one page within a website to another page. For example, linking from within your blog post to a product page on your site is an internal link. Unlike external linking (links to other sites), internal links are completely under your control and are a very important part of your SEO strategy.

SEO Benefits of Internal Linking

1. Crawlability & Indexing:
   • Search engine bots (such as Googlebot) use internal links to explore your site and index new pages. A robust internal link structure allows bots to reach all the important pages on your site and crawl them more efficiently.
   • If you want a newly published page to be quickly indexed, it is quite effective to internally link to that new page from an existing high-authority page.
2. Authority Distribution (Link Equity/PageRank Flow):
   • The “link juice” or “authority” (PageRank) that a page has is distributed to other pages through all internal links that leave that page. When you link from a page with higher authority, to a page with less authority but important, you increase the authority of that page. This can help that page rank better in search results.
3. Keyword Rankings:
   • Anchor Text: Link texts (clickable words or phrases) used in internal links give search engines clues as to what the linked page is about. For example, when you link to a page with the word “SEO strategies”, you indicate that the page is about SEO strategies.
   • Using relevant and natural link texts without keyword stuffing can support your ranking on related keywords.
4. User Experience (UX):
   • Well-structured internal links make it easier for users to navigate your site. Links to related content or products help users find the information they are looking for and encourage them to stay on your site longer.
   • Longer stay time and less bounce rate signal search engines that your site is valuable and useful.
5. Site Architecture and Hierarchy:
   • Internal linking clearly shows the hierarchy of your site and your most important pages to search engines. Usually, the home page has the highest authority, and this authority spreads to other pages of the site with internal links coming from the main page.

Best Practices for Internal Linking

• Natural and Related Links: Place links in such a way that they are always useful to the user and relevant to the content. Instead of just linking for SEO, put user experience first.
• Avoid Over-Optimization: Avoid repeatedly linking from the same page with the same link text. Also, do not do keyword stuffing. Let your link texts be natural and varied.
• Link to Authorized Pages: From pages with high PageRank or authority, link to pages that are less powerful but want to increase their ranking.
• In-Content Links: Within your blog posts or articles, provide links to other related blog posts, product pages, or category pages. This is one of the most effective types of internal linking.
• Check for Broken Links: Regularly check and fix your broken internal links. Broken links negatively affect both user experience and SEO.
• Navigation and Footer Links: Links in the main menu (header navigation), sidebar, and footer are also an important part of internal linking. These should usually be directed to the most important pages of your site.
• Pay attention to the number of links: Too many internal links from a page can lead to excessive distribution of link water. Try to provide a reasonable number of links (depending on the length and complexity of the content, usually 5-15 is a good starting point) for each page.

Internal linking is a powerful tool that is in your control, which can significantly affect the SEO performance of your site. When used correctly, it allows both search engines to understand your site better and users to have a better experience.
