Today’s post will be very short but very useful for all the web marketers sharing URLs on Facebook.
You might have noticed that sometimes the info displayed via the Facebook sharer doesn’t correspond to your latest website description or illustration, which can be annoying. You need to know how to clear the meta data in Facebook cache.
There is a way to force Facebook to fetch the latest version of your website (or basically of any website).
Simply use Facebook DEBUG TOOL which you will find here.
Type in the URL for which you want to fetch a fresh version and press Debug.
Then press Fetch new scrape information.
and you will see below the latest version of your website details, as fetched by Facebook bot.
If you don’t have any header image attached to your site, Facebook will fetch one of the images contained in one of your posts / pages. If you want to force a specific image to be displayed when sharing your root URL (and not a specific article), you have to declare it in the meta tags of your site, in the <head> section.
Here is the structure of the Open Graph meta for the main image (you will find other types of meta instructions here):
<meta property=”og:image” content=”http://locationofmyimage.com/image.jpg” />
Ideally, you should use images that are at least 1200 * 630 pixels, as detailed in Facebook best practices, which you can find here.
