Everyone has seen it or had it happen to them. You share a web page you know has a photo/video and Facebook does not see it. Another common issue is that you change the photo/video or edit the headline/text and Facebook does not see the changes.
Facebook Scraper to the rescue. Using this tool to clear Facebook’s cache is indispensable in my opinion. In a perfect world Facebook’s auto-scraping of your shares would precede display, but in the real world it often fails to keep up, so you need to manually reset the cache. Super easy.

Press the ‘Debug’ button
Press the ‘Scrape Again’ button (Occasionally you will have to do this several times. I had to do it 3 times for this article)

The Facebook Debugger/Scraper also shows various other Open Graph settings which may be beyond your ability to change unless you have admin access to blogging software like WordPress which allows customization of these settings.
Social media posts with good images ALWAYS get significantly more views and shares, it is a fact.
