Context must justify the reference
A contextual link should help a reader continue a relevant task, verify a point or access a useful resource. It should not be inserted merely because an article has authority or traffic.
Review the existing article
Read the whole section, confirm the topic, check the quality of existing external references and identify a natural location. The independent website must approve the addition.
Validate the destination and anchor
The destination should be live, secure, relevant and accurately described. Use a natural anchor. A website operator may adjust wording or link attributes for editorial or disclosure reasons.
Confirm current conditions
Availability, article suitability, price, timing and future retention can change. Confirm them in writing before payment.
Know the limits
No insertion guarantees ranking, traffic, indexation, conversions or permanence. Requests for restricted, deceptive or unlawful destinations are declined.
