BAbacklink-guard
backlink-guard checks a link source — directory, awesome list, or guest-post site — before you submit your site to it, giving each site an action (skip, look first, free only, low value, submit) and a verdict with the evidence, against Google's link spam policies. It verifies listings once live, audits your own backlink profile, and surfaces the sites linking to competitors but not to you — usable as a CLI, an agent skill, a Claude Code plugin, and an MCP server.
