At this moment I am working on a big update, adding a solution for the favicon problem Mike said in his post MikeJones, also adding Pages (extension) support, editing robots.txt support and a greath SEO health-check page in the admin panel. It's going to be a great update! From then on the extension will leave the beta phase!
Now, my question is, when you see the following health-checks. Do you miss something? Let me know what you think about this update! 
JasperVriends Flagrow Upload extension support or adding first image in discussion to be thumbnail on social media share
pxnji You mean, detect if there is an image in the topic and then using that image as social media image?
I tried to install the repository from the github, but after clearing the cache on the site, the admin panel files were deleted (not extensions)
Alkir I was missing the dist files in the git repo. You can try again
Ok, I'll try tomorrow
JasperVriends or at least the possibility to specify a default social image, otherwise the favicon will be taken, and it will not look good
EDIT: just saw the check "social media image", so I guess the feature is already there?
matteocontrini Yes it is already there and build in! It will be available at release
JasperVriends just pulled the GIT version of this - looks fantastic. Thanks for an excellent extension.
JasperVriends Yes, like that.
pxnji Hmm, I'm not very sure if that's good, as you cannot check the resolution of the image that's in the discussion. The good thing is that you can now set a default social media image in the new version, so forum owners are ensured that the forum (posts) will always have a quality image on social media.
But I may make an extra option to disable the social media image on topics. You can create an issue on GitHub as request https://github.com/v17development/flarum-seo/issues
JasperVriends when will the release be released?
Alkir Within a few hours

Excited to upgrade when I get home!
I'm glad you updated this plugin, which I think is very important for flarum. Thank you so much.
There's something I'm curious about. I noticed that the tags didn't produce a dynamic for
<head>
<title>tag name-forum title</title>
</head>But this is not the case for the pages.
wwwn Thank you for your kind words! 
I'll look into that, maybe you can make an issue on GitHub for this? https://github.com/v17development/flarum-seo/issues, thanks in advance!
@JasperVriends I know this extension adds some rows to the settings table, but whilst troubleshooting an issue with another extension, I removed these entries manually from the database. I'm now getting errors on this extension (I think) because the rows no longer exist in the database, but I can't seem to get them back - even by fully removing and re-adding the extension. Any thoughts ?
Thanks
