When reviewing a specific page within the Optimization section of Page Performance, you will notice metrics in the left-hand menu, including Inbound Links and Internal Links. While both metrics show links to your pages, they are each definied and calculated differently:
- Inbound Links are links from other websites to yours. These are first calculated by HubSpot and Moz when your HubSpot account is initially created. After the initial crawling of your website, we do not continue to pull in data from Moz (you can see a similar Moz report for inbound links to your domain by checking out their Open Site Explorer). However, we will still continue to update your inbound links and referral data within HubSpot's Sources Report (Reports > Sources > Referrals). As visitors click on links from other sites to yours, we will verify the link and add it to your Inbound Links data.
- Internal Links are links to your page from other pages on your own domain. Page Performance crawls pages based on your Target Domain (Reports > Reports Settings > Target Domain).
