404 error for unknown URL that Moz is finding in our blog

[MessinaGroup]

I'm receiving 404 errors on my site crawl for messinastaffing.com.  They seem to be generating only from our blog posts which sit on Hubspot.  I've searched high and low and can't identify why our site URL is being added at the end - I've tried every link in our blog and cannot repeat the error the crawl is finding.  For instance:

Referer is:  http://blog.messinastaffing.com/take-charge-career-story-compelling-cover-letter/

404 error is:  http://blog.messinastaffing.com/take-charge-career-story-compelling-cover-letter/www.messinastaffing.com

I agree that the 404 error URL doesn't exist but I can't identify where Moz is finding it. I have approximately 75 of these errors - one for every blog on our site.

Hi Beth,

Did you check all the URLs that might be relative as well? It feels like one of your outgoing links might be missing the http:// part which makes crawlers think that the URL is relative.

Agree with Martijn - this is almost always caused by a link not properly including the http(s):// at the beginning..

Since it's occurring an all blog posts, it's likely a link in the navigation/sidebar/footer or other templated area of the pages.

You'll need to look in the pages' source code to find it.

[UPDATE] Yup, it's an incorrectly formatted link on line 100 of the page - part of your header menu.

• class="hs-menu-item hs-menu-depth-1 hs-item-has-children"><a <span="" class="html-attribute-name" data-mce-mark="1">href</a><a <span="" class="html-attribute-name" data-mce-mark="1">="</a>www.messinastaffing.com">Staffing Divisions

  You can see the href is missing the _http.
