I have a website that is about 9 months old that hosts and distributes a desktop utility/productivity tool. Never had issues with Google, but I have a continuous streak of very frustrating experience with Bing.com. The site was deindexed from the start but I was not aware of that until early summer when I added it to their webmaster tools. After my initial appeal it was added to the index (after a month of waiting), only to be removed again a few days later.
After every interaction with webmaster support team, I am only encouraged to read their guidelines, but they refuse to tell me exactly what is wrong, so I am left guessing. Website is professionally made, with some basic on-site SEO and no bad off-site SEO was ever employed. The executable is signed with an EV code signing certificate that belongs to our organization. SSL is obviously working, we got a redirect from www to non www domain and I also added canonical tags to all our pages, which is apparently a big deal for Bing in terms of duplicated content.
What make this really strange is that it used to say in webmaster tools that the site was not in index, but after 2nd removal it says now:
Indexed but cannot be served
And below:
The inspected URL has been indexed successfully but there are some issues which might prevent us from serving it to our users. Please contact Bing Webmaster support for more details.
By now I assume the contact Bing for more details is an inside joke.
I don’t know what to do anymore. I know Bing is way smaller than Google, but I was ranking well the short time it was in index and I could really use the free traffic from it. Should I move it to Azure hosting? Do I need to obtain some additional certification? I keep asking them for specifics but I never get any.
