What Are Link Building Sites and Why They Matter

Link building sites are online platforms that allow businesses and individuals to create profiles, share content, or submit their websites to gain backlinks. These backlinks act as endorsements from other trusted sources — signaling to Google and other search engines that your website is credible, valuable, and authoritative.
