helps avoid potential negative consequences in your rankings in Google Search.
Links can provide more context on a topic, both for users and search engines, which may help
demonstrate your knowledge on a topic. However when you're linking to pages outside of your
control, for example content on other sites, make sure you trust the resource you're linking to.
If you can't trust the content and you still want to link to them, add a
`nofollow` or similar annotation
to the link to avoid search engines associating your site with the site you're linking to. This
helps avoid potential negative consequences in your rankings in Google Search.
