Linkody is a dedicated backlink monitoring tool — it tracks who links to you, alerts when backlinks are lost, and watches for toxic links pointing at your domain. StoreVitals monitors the health of your own site: SEO, security, performance, and accessibility. These tools solve completely different SEO problems.
Linkody and StoreVitals solve different halves of the SEO health equation. Linkody is the outside-in view: who is linking to your store, are they still linking, and are any of those links toxic? StoreVitals is the inside-out view: is the store itself technically healthy, secure, fast, and accessible? Most serious ecommerce stores need both kinds of monitoring, but they're complementary not competing. If you're choosing one to start: pick StoreVitals if your site has technical issues you haven't yet quantified (most stores do); pick Linkody if your onsite SEO is already solid and you've moved into link-equity management as your next growth lever. Many stores run both — they cost less combined than a single Ahrefs subscription.
