Difference between urls and referring urls?

[ayrutd]

Sorry, nit new to this side of SEO

We recently discovered we have over 200 critical crawler issues on our site (mainly 4xx)

We exported the CSV and it shows both a URL link and a referring URL. Both lead to a 'page not found' so I have two questions?

What is the difference between a URL and a referring URL?

What is the best practice/how do we fix this issue? Is it one for our web developer?

Appreciate the help.

I believe "URL" is the page on your website that is 404ing/Broken, the "Referring URL" is the website someone found your URL on and clicked through to. For example, if you had a broken link on a Facebook post you did, it would show the URL as "yourwebsite.com/examply" (broken link) and the Referring URL would be "facebook.com/yourprofile".

No. The referring URL is a page on your site that has a broken link on it. These are damaging your rankings so so fix ASAP.  Go to all the referring pages and fix or remove the links with the URL in.
