Locally installed WordPress

Incoming links show sites that are linked to your websites URL. Your local install address is (presumably) https://localhost/wordpress/ (just like the thousands of other people who’ve installed locally). Since that address is commonly referred to across the internet it appears in your incoming links section. It doesn’t mean anyone has actually linked to posts you’ve written on your locally installed blog. That would be impossible since no one but you can see it. Did you even check the “incoming links”? I don’t think so because if you had, you’d have seen that they’re associated either with gibberish or articles/questions/etc about installing locally.
