SEMrush is flagging some of our pages as having broken external link even though the link is opening fine. This particular example is being flagged with http code 403 but we can open the link given on the page. Please suggest what am I missing here?
The website https://httpstatus.io/ is returning a '200' status for that page, so I suppose it is SEMrush that is mistaken.
Have you tried recrawling the page? Perhaps it was a one-off issue.
Alternatively, what did the SEMrush support team have to say about this?
