The document states, "OTS must be specific to a particular channel. I completely agree with that.

The document further in the same paragraph states, “For Facebook it is the number of fans to a page."

In shortly engagement will increase OTS beyond the number of fans by drawing from the Friends of Fans “network. Further, paid promotion on Facebook will greatly increase the OTS and provide (beyond the paid OTS) a natural organic viral spread of the message which is 100% EARNED; thus the OTS shouldn't be limited to just the number of Fans.

Here are my thoughts in more detail.

Limiting OTS (on facebook) to fans of a page is fundamentally flawed, albeit easy to compute. There are several reasons why this is flawed, but primarily three major considerations which impact OTS on Facebook. The first issue is the percent/dollar value (if any) of paid promotion. The second reason is the impact of EdgeRank. Thirdly, there is the complex relationship on Facebook of engagement, EdgeRank and OTS

This third issue is highly complex. A fan page with 5700 fans may have a "friends of fan" network of more than 1.6 million people. Depending on if, how or when promotion is paid for and depending on who and how fans engage with the page depends on how many people EdgeRank will allow to see the post. If we are looking for a true baseline of OTS and need a simple easy to compute number the Friends of Fans is far more accurate, although harder to achieve.

The point is just because a page has a 1 Million Fans doesn't mean there is 1 Million OTS; it could be far higher (because of high engagement and the Friends of Fans “network” or lower (because of low engagement and Edgerank). To be fair no matter how good the engagement EdgeRank is always going to limit OTS.

Understanding that PR measurement is trying to measure Earned media, we have to understand that Facebook is an amalgamation of Earned, Owned, Paid media, and as in the real world each of these influences each other.

Facebook breaks out impressions, reach, and many other metrics on a post by post basis. It is my belief that an easy to compute but complex ratio of these metrics including the number of people in the Friends of Fans “network” would yield a far more accurate measurement of OTS on Facebook fan page.

Assuming that a page has at least the average PTAT ratio of 2%, implying a basis level of engagement; the true OTS for a post is in far excess the total number of Fans, even though EdgeRank may simultaneously prevent many of the fans from seeing the post.

I have clients with PTAT that range from 10-50%

Paid promotion on Facebook will greatly increase the OTS and provide (beyond the paid OTS) a natural organic viral spread of the message which is EARNED; that needs to be measured.
