Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Can you please share the website URL in the sensitive data section?
We look forward to helping you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
I checked your website on Google, most of the pages are indexed on Google, as the URL is on Google, there is technically no reason for it to not be included in Bing, unless Bing has some reason to not index a page like DMCA, copyright content, nulled content, etc.
You can contact Bing support and ask them the exact reason as from checking the page’s source code, there are no apparent issues.
You can refer to all the Webmaster Guidelines and see if your website is violating any guidelines.
I hope this helps. Looking forward to helping you.
Hi,
I have checked and followed the Bing guidelines.
I didn’t violate any of their guidelines which may lead to delisting(which I know is very rare).
I would be delighted to have you assist me further.
thanks
