In SEO, link building is consistently one of the most crucial factors for improving website rankings. However, manually finding, analyzing, and managing links can be very time-consuming. That is why Chrome extensions have become a “powerful assistant” for SEO experts. This article will introduce the 10 best link building Chrome extensions in 2026, helping you optimize the process faster and more effectively.
