Partner and supplier links are the most overlooked and most accessible source of backlinks. Most companies have existing relationships that can be turned into a mention: manufacturers keep lists of authorised dealers and service centres, software vendors keep lists of certified partners, and customers publish references and case studies. It is enough to reach out and ask for the entry to be added or updated with a link. Another option is a joint case study, which delivers a link and business content at the same time. These links have thematic relevance and natural context, which is exactly what has value. A practical step is to go through the list of business partners from recent years and check where the company is listed and where it could be.
