Link building is an essential aspect of SEO optimization that can significantly impact your website’s ranking in search engine results pages (SERPs). As a website owner, managing multiple domains with the same content or niche, you may wonder how to link domains to improve SEO for all of them.

In this article, we’ll discuss the best SEO practices for interlinking domains and how to achieve the best possible outcomes for all websites.

Why Link Domains?

Before we dive into best practices, let’s first discuss why linking domains is important. Interlinking domains from one to another can have numerous benefits for your website’s SEO optimization. By linking domains, you create a network that allows users to navigate between related sites with similar content. Moreover, search engine crawlers can crawl and index linked pages from different domain names, which can improve the organic visibility of all linked websites in search results.

Best Practices for Linking Domains of Multiple Websites

1. Ensure Relevance and Quality

The linking of domains should be relevant, beneficial and of high quality to improve SEO ranking. Relevancy refers to the similarity of the content found on the linked sites. Therefore, before interlinking your websites, ensure that the content on the different domains is similar, if not identical. High-quality links mean that the domain linking to another domain provides quality content that is authoritative and relevant.

2. Use Anchor Text

Anchor text is a clickable hyperlink phrase that links the domains. Using descriptive and keyword-rich anchor text helps search engines understand the content of the linked site, which optimizes the link weight between domains. However, avoid overusing exact match anchor text, as it can lead to Google penalties.

3. Avoid Linking Spammy Websites

Avoid linking to irrelevant, low-quality or spammy websites, as this might negatively affect your website’s SEO ranking. When linking domains to achieve the best SEO for all of them, maintain high-quality standards and avoid linking to websites with a bad reputation.

4. Use Links in Various Forms

Use the different forms of links to link your domains effectively. The most common link types include internal links, external links, natural and contextual links, image links, and social media sharing links. Use the various forms of links to create a comprehensive SEO strategy for your website.

5. Monitor Your Links Regularly

Monitoring your linking domains regularly helps you identify any broken or low-quality links that might hurt your website’s ranking. Use SEO tools like SEMrush, Ahrefs and Google analytics to monitor your domain links’ metrics regularly.

6. Use a Good Linking Strategy

Avoid linking the same domains to each other cyclically. Instead, create a linking strategy that incorporates the batch linking technique. By batch linking, link a few domains together at a time rather than having one domain linking to all others at once.

Example of How to Link Domains of Multiple Websites

Let’s consider an example of how to link domains of multiple websites using an e-commerce site that sells clothes for women and men as a scenario. If the website sells men’s clothing on one domain and women’s clothing on the other domain, linking the domains can help improve the website’s overall SEO optimization.

For example, if you write a blog post on the men’s clothing website that talks about “the best jackets for winter,” you can link it to the women’s clothing website by using the anchor text “Winter Jackets for Women.” This helps to create an interlinked site network that improves both domains’ SEO ranking while enforcing the relevancy of topics.


Linking domains of multiple websites is an essential aspect of SEO optimization that can improve your website’s organic visibility and search engine ranking. The best practices discussed here will help you achieve the best possible outcomes for all websites. Remember to maintain quality, optimize your anchor text, use various link forms and monitor your links regularly while creating a good linking strategy. By considering these best practices, you can link domains of multiple websites for the best SEO optimization results.
