Just a quick one as I forget that people are not aware of this tool.
After any major update or build of your website you usually want to show it off in Facebook. Only to find that the website Facebook shows in the post is your old one.
This happens because of something that Facebook calls scraping. When a website is URL is entered into a post or a messenger post then Facebook ‘scrapes’ that website and stores a copy of it. This is to reduce time and data for the future. But as anything in a cache this can go stale. So what can you do? Just wait? NO!
You can force Facebook to re-scrape your site. And in at the same time check for other problems.
