External Resources
External Resources lists everything off your domain that your pages reach for: third-party scripts, stylesheets, fonts, images, and the outbound links your content points to. Every external resource is a dependency you do not control — each one is a potential performance cost, a privacy surface, and a point of failure if the third party slows down or disappears. Outbound links, separately, are part of the trust profile your pages project. This view is where you audit both.
What you’ll need
Section titled “What you’ll need”- A project with a completed audit. External references are extracted from the pages the crawler fetched in the latest run.
What you’ll see
Section titled “What you’ll see”The off-domain references found across your crawled pages, grouped by kind.
| Type | What it is | Why it matters |
|---|---|---|
| Scripts | Third-party JavaScript loaded from another domain | Blocks rendering and runs code you don’t control; the most common performance and privacy cost. |
| Stylesheets | CSS pulled from an external host | Render-blocking; a slow third-party host delays your page. |
| Fonts | Web fonts served off-domain | Adds requests and can shift layout while loading. |
| Images | Images hotlinked from another domain | Outside your optimization and caching; breaks if the host removes them. |
| Outbound links | Links from your content to other sites | Part of your link profile and what you signal you endorse. |
How to use it
Section titled “How to use it”Read the resource list as a dependency inventory. Look for third-party scripts you no longer need, duplicate tools loading the same thing twice, and resources from hosts you don’t recognize — each one you remove is a request saved and a dependency dropped. For resources you must keep, confirm they load from reputable, fast hosts.
For outbound links, scan the destinations. Check that they point where you intend and that links you don’t want to vouch for carry the appropriate rel attribute (nofollow, sponsored, or ugc). Broken or redirecting external links are worth fixing so visitors and crawlers don’t hit dead ends.
