Bing indexing at a tiny fraction of Google

[Porch]

I've read through other posts about this but I can't find a solution that works for us. My site is porch.com, 1M+ pages indexed on Google, ~10k on Bing. I've submitted the same sitemaps, and there's nothing different for each bot in our robots file. It looks like Bing is more concerned with our 500 errors than Google, but not sure if that might be causing the issue.

Can anyone point me to the right things to be researching/investigating? Fixing errors, sitemap crawling issues, etc. I'm not sure what to spend my time looking into...

This is normal, try some other sites you will see that same pattern.

Bing stated they don't want every page, they don't want junk, they want only the important pages.

Thanks for the response. Google isn't just indexing the pages, they're sending a significant amount of traffic to them as well. Of course, not all 1M pages are the same quality, so would it be better to have a sitemap of just the highest quality pages and see if Bing will index more of that list?
