Meta Tags for FB share - do I need to use regular meta tags as well? what type to use for an html5 game?

Question

I have a FB share link in a game I just published on a website, and don't really know the rules for meta tags on an html page. I have the og tags set up from looking at this document: https://developers.facebook.com/docs/sharing/webmasters/

Questions:

• Do i also need regular meta tags - like description, keywords, etc? Or if I use the fb tags, is that all that's needed?
• Do meta tags take a while to kick in? I set the og tags, and the FB share window still shows old info
• I have the type set up as "website" - is that the og type I should use for an HTML5 game?

Answer 1

• Yes, you should also provide regular metatags
• Refresh the tags in the debugger if the are not correct: https://developers.facebook.com/tools/debug/
• There is no specific game tag, so "website" should be alright: http://ogp.me/
