BacklinksAI is a free SEO tool which simplifies backlink building using the HARO (Help a reporter out) technique. You can configure the tool to subscribe to backlink opportunities only relevant to you, using filters and rules to avoid irrelevant sites. The tool also lets you use AI to craft auto-replies to secure backlinks in articles.
Update: Sadly, BacklinksAI is no longer available as the developer has temporarily paused the project. We will update this page if we hear of any further updates to the tool.
