A note on methodology. This data was conducted and published by Editorial.Link, a link building agency. While the sample includes a mix of 518 SEO professionals (from agencies, freelancers, and in-house teams), the company’s business model centers on selling link building services.

• Some findings, especially those highlighting the continued importance, difficulty, or rising cost of link acquisition, could reflect the perspectives or priorities of professionals more immersed in (or reliant on) link building than the broader SEO community.
• As with all industry surveys, readers should consider the context and potential for self-selection bias when interpreting the results.
