Broken link checkers are one of those invisible but critical pieces of SEO infrastructure that most founders forget about until a customer reports a 404. The fact that this runs in the cloud means no plugin bloat, which is huge for site performance. The automated background scanning is smart - catching link rot before it tanks your SEO is exactly what solo founders need. One question: does the background scanner check anchor links within pages, or just external broken links? That's usually where most teams get stuck.
