Hey Jacob:
- Do you use Screaming Frog? would be great to double check if there's any directive with noindex that it's hurting your .be visibility (about a few of your pages are being indexed). The "site:" command it's pretty useful to use it on-the-fly, but I would recommend always to check if the URLs in the sitemap.xml are being indexed. Wait 1-2 days to see if after submiting your sitemap there's any change
- I assume you are using Wordpres in a Apache server running php, so, in your File Manager (cPanel) or your FTP software, go to the root directory (one level up to public_html), you should have a "logs" folder with a couple of compressed files. Un-zip them and open it with Notepad or any text editor. Search for Googlebot in the logs and see the most recent request from Googlebot
- Yoast it's a good plugin, I use it, but for this case, maybe should be good to deactivate this feature of the plugin and search for another than can handle hreflang, or do it manually
- Yes, maybe your .be ecosystem is pointing to the .nl site, check it with Open Site Explorer and if this is the case, request a change of domain of each site owner. If not, you should begin to build those links in a proper way
