Definition
Reciprocal links (or link exchanges) consist of an agreement between two websites to mutually link to each other. This was a very common practice in the early web, but Google has reduced the value of these links because they are easy to manipulate. An occasional and relevant link exchange between complementary sites remains acceptable, but massive and systematic exchanges are considered a link scheme violating Google's guidelines. The Penguin algorithm detects large-scale link exchange patterns. A more natural alternative is the three-way link exchange or triangular exchange.
Key Points
- Massive link exchanges are detected and devalued by Google
- An occasional, thematically relevant exchange remains acceptable
- Three-way (triangular) exchanges are harder to detect
Practical Examples
Acceptable exchange
Two partner companies in the same sector exchange a link on their respective Partners pages. It is a natural, limited exchange that poses no problem.
Abusive exchange
A site exchanges links with 500 unrelated sites, placing all links on a dedicated 'Partners' page. Google easily detects this pattern and devalues these links.
Frequently Asked Questions
Google does not automatically penalize all link exchanges. An occasional and relevant exchange is acceptable. What is penalized is systematic, large-scale exchange for the purpose of manipulating rankings.
Prefer guest posting, digital PR, broken link building, and natural links earned through quality content. If you exchange links, limit yourself to a few thematically relevant partners.
