Facebook now includes viral shares in pages’ People Talking About This counts, the company tells us.

This means that when fans share a page’s post, any subsequent Likes, comments, or re-shares will be counted in a page’s PTAT. Previously, actions that users’ friends took on a shared post were not added to PTAT. The new calculation is likely to be more representative of the actual number of people talking about a page.

Some pages have already seen a large increase in PTAT as a result of the change, which went into effect last week. The most significant increases can be seen on pages that receive a lot of shares. For example, George Takei and Jesus Daily are among the top talked about pages on Facebook. These pages regularly get thousands of shares per post and sometimes more than 30,000 shares on a single photo. PTAT is indicated by the green line below.

The same trends can be seen among pages like “Amor não se escolhe. Acontece” and “Pra toda mulher,” which get fewer shares per post, but make dozens of posts each day that receive hundreds or thousands of shares.

However, brand pages with the most Likes have not necessarily seen PTAT grow the same way, since these pages do not post as frequently and receive far fewer shares.
