Facebook "Like" icon

The Facebook JavaScript used to load and display the Facebook "Like" icon is asynchronous. It will not block any other page items from loading prior to the icon loading and being displayed.

After your page has finished loading, there may be a short delay before the Facebook "Like" icon appears. Merchants are advised that Facebook's JavaScript is approximately 112 KB in size. The loading of this icon and the time it takes to be displayed are handled by Facebook, and not Yahoo!. Because this is handled by Facebook, Yahoo! cannot change the way in which this feature loads.

The Facebook "Like" option will be cached after a customer loads a product page containing the Social Media Sharing module, and should appear almost immediately when viewing other pages that include this feature.

Note: When you add a new product, or first enable the Social Media Sharing feature for your products, you may notice a time delay between publishing your changes and when Facebook recognizes the "Like" function on the product page. This time delay issue is on Facebook's end, and because of this, Yahoo! cannot change how these updates are handled by Facebook.

When this delay occurs and a user clicks the "Like" icon on a product page, a message noting that Facebook is unable to reach the page will be displayed beside the "Like" icon. In some cases the delay lasts for only 1 to 5 minutes after publishing, and in other cases, can take an average of 15 minutes to resolve. If this does not resolve after an hour, then any errors seen as a result of clicking the "Like" icon may be as a result of a different issue.

Facebook Open Graph Meta Tags

When you provide a Facebook Application ID, Facebook Open Graph Meta Tags will be added to your store's index page. These meta tags should not affect page load time for your store.
