Images showing up as pages in Google

We reviewed several of the URLs in question and do see that there are attachment pages among the URLs that are appearing in Google’s results. For example we found:

https://www.commink.com/casestudieslanding/concord-academy-case-study/cilogo/
https://www.commink.com/casestudieslanding/concord-academy-case-study/ca-ebook2/

Also, we checked on your attachment sitemap at https://www.commink.com/attachment-sitemap.xml and confirmed that URLs were listed.

We would first recommend ensuring that the attachment URL redirect setting is set to redirect to the attachment. To set attachment URLs to redirect to the attachment itself you would need to perform the following actions:

In WordPress go to SEO>Search Appearance>Media
Set ‘Redirect attachment URLs to the attachment itself?’ to Yes
Click ‘Save Changes’

We also have more information on redirecting media attachments and this setting in the following article: https://yoast.com/media-attachment-urls/

Thanks, I actually did install the search index purge plugin, and it pretty quickly cleared out most instances of attachment pages being listed. A few remain, but hoping they will eventually be cleared out also.
