When sharing your website on Facebook, it will show your website title, description and image to use. You can edit these in your website builder settings.
Please note that Facebook, Google and other social networks cache information, and therefore need to be updated. More instructions on this below.
Facebook caches your website title, image and description. It's very possible that if you share your website URL on Facebook often, it will show an outdated website title, image and description. To update Facebook, use the Facebook debugger to scrape recent information for your website.
Google caches your website information. If you search on Google for your website and see that the title, description, etc. are old, it's because Google has saved this information before and is using their outdated version. This is outside of ArtStation's control and all we can do is make sure the correct information is showing on your account. Google may recrawl your website at any time and you can also request a recrawl of your website to speed up the process.
