Link Exchange
Link exchange refers to an agreement between two websites to link to each other. The idea is simple: "You link to me, and I’ll link to you." This practice is often used to build backlinks and improve search engine visibility.
While link exchanges were once a common SEO tactic, search engines like Google now treat them with caution. When done thoughtfully and in moderation — especially between relevant, trusted websites — they can still be helpful. However, excessive or unnatural link swapping can lead to penalties.
How link exchange works
A typical link exchange involves two webmasters or site owners who agree to include hyperlinks to each other’s sites. The links might appear in:
- Blog posts
- Resource pages
- Partner or affiliate lists
- Footers or sidebars
Sometimes, the exchange is informal. Other times, it’s a formal partnership where each site features a dedicated link to the other.
When is a link exchange considered safe?
Google's guidelines allow natural link exchanges when there’s a genuine reason to reference each other’s content. This includes:
- Citing a trusted source in a relevant blog post
- Partner websites linking to one another
- Authors or contributors linking to each other’s work
If the exchange improves user experience and is contextually appropriate, it’s unlikely to cause SEO issues.
Risks of link exchange
Overusing link exchanges — especially with low-quality or irrelevant sites — can be viewed as a manipulative link scheme. This can hurt your SEO in several ways:
- Algorithmic penalties from search engines
- Loss of link equity if linking to untrusted or spammy domains
- Reduced credibility if users see irrelevant or forced links
Google’s take on link exchanges
According to Google’s Spam Policies, excessive link exchanges can violate their rules:
“Exchanging links excessively ("Link to me and I'll link to you") or exclusively for the sake of cross-linking” is considered a link scheme and may negatively impact rankings.
HTML example of a link exchange
<!-- Site A linking to Site B -->
<a href="https://example-b.com">Check out our partner's services</a>
<!-- Site B linking back to Site A -->
<a href="https://example-a.com">Visit our trusted partner</a>
In this example, both sites are linking to each other, ideally with relevant context and value to users.
Best practices for ethical link exchanges
- Only exchange links with relevant and reputable sites
- Make sure links are contextual and useful for visitors
- Don’t automate or mass-produce link swaps
- Avoid exact match anchor text that looks manipulative
- Use nofollow if the link is not editorially earned or is sponsored
In summary, a link exchange is when two websites agree to link to one another. While it can still be a useful way to build relationships and share traffic, it must be done carefully. Focus on quality, relevance, and user value — not just SEO gains — to avoid penalties and build genuine authority.
