Judging by all the press coverage, Facebook represents the advertising Holy Grail -- but most marketers still have no idea if it's any good for, like, advertising. At least that's
according to eMarketer, which recently published the results of a survey of chief marketing officers about their use of social media. Overall less than half of the 175 execs surveyed by Bazaarvoice
and The CMO Club on eMarketer's behalf even knew what kind of ROI Facebook was delivering -- and of these, the majority rated it just "average."
Specifically, the eMarketer survey found
that just 15.4% of the respondents believed Facebook was delivering "significant ROI," while 20.6% said ROI was "average" compared to other social media sites. A small group -- 8.6% -- said
Facebook was failing to deliver ROI. Another 20.6% weren't using Facebook, and the largest group by far -- 34.9% -- said they didn't know one way or another.
These results may sound pretty
mediocre, because they are... but Facebook was actually the leader in social media ROI in the eMarketer survey. For example, just 11.4% of marketing execs surveyed said Twitter produced
"significant ROI," 12% said it was "average," and 13.1% said it failed to deliver ROI -- but a whopping 40% said they had no idea what Twitter's ROI was (the remaining 23.4% don't use it). For
LinkedIn, "significant ROI" was 10.9%, "average" was 10.3%, "no ROI" was 18.3%, and "don't know" was 36%. For industry blogs and online forums, the "significant ROI" figure slipped to 8.6%,
"average" was 23.4%, "no ROI" was 7.4%, and "don't know" was 37.7%.
All this paints a pretty dismal picture of the social media marketplace -- not so much because social media isn't
working well, but because most marketers simply have no idea whether it's working at all. The same survey sought to determine which metrics are most popular for ROI, and the answer is "all of
them": the responses were all over the map, and many of the most popular ones were also clearly insufficient.
Thus the top metric was site traffic, endorsed by 68% of CMO respondents,
followed by number of fans/followers, with 62.9%, and number of positive customer mentions, also at 62.9%; while these may be a good start, I think most would agree they are no more than that -- a
start. There were some moves to more concrete measures, but not many: the single big change in the top ranks was increasing popularity for "conversion," which jumped from 32.6% of respondents in
2010 to 65.7% in 2011. Meanwhile revenue, which strikes me as a self-evident winner for ROI, increased from 29.1% of respondents to 49.7% of respondents over the last year.
