Your page lacks internal links.
Internal links are hyperlinks within a website that connect different pages. They are important for SEO for three reasons: they help search engines understand the website’s structure, pass authority to web pages, and assist users in navigating the site. There are various types of internal links, including navigational, footer, contextual, and sidebar links.
Here are best practices for internal links:
- Use keyword-rich anchor text in internal links.
- Link to important pages on your site to send link authority.
- Utilize a pyramid-like structure for internal linking.
- Implement contextual and structural internal links on your site.
- Use tools to analyze site indexation and optimize internal linking.
