G+ Communities: Significant and Recent Activity
We're continuing to get a sense of G+ Communities and how many of these are significant, active, and have some sense of vitality.
One metric is to look by both size
and recent activity
.G+ Public Communities with Recent Activity
Members Week Month
1,000 28,823 39,301
100 63,874 105,166
is the reported membership of the community on its Google+ landing page. Comparison is greater than or equals.
Recency is assessed as the sampling time minus the most recent post activity, both expressed as Unix timestamps (seconds from 1970-01-01:00:00:00). Week
is activity within 86000 * 7 seconds, Month
is activity within 86000 * 31 seconds. Comparison is less than or equals.
From previous analysis, it's likely that only 10-20%, generously
, of these communities have substantive interaction between users, as opposed to other activity, including spam or link-drops. We have not investigated this dataset yet to assess this characteristic.
Still, that would leave about 3,000 - 6,000 communities of 1,000+ members with weekly or better activity,
and 4,000 - 8,000 with monthly activity,
and 6k - 12k and 11k - 22k of 100+ members respectively
There is little
relationship between active engagement, measured by plus-one, comment, and reshare activity, and community size. While smaller
communities (especially below 100 members) are far more likely to have no activity or no recent
activity, the distribution of significant recent activity is fairly uniform across a very broad range of community sizes. On a per member
engagement level, the sweet spot appears to be roughly 100 - 5,000 members, though we need to investigate this further.Very large G+ communities are frequently not particularly engaged.
See the WhatsApp Community
(6.8 million members) as an example. Interestingly, this doesn't appear in a G+ Community search for "WhatsApp".
URLs for 8,107,099 Google+ Communities were read, with 3,559 found to be deleted when accessed, and 8,103,540 read successfully yielding data.
There were 7,303,513 public, and 800,382 private communities (9.877% private). Membership and post activity are available only for public communities.
Membership status was open ("Join") for 3,689,488 (45.51%), and closed ("Ask to join") for 4,414,407 (54.45%) communities, status was unavailable for 3,204 (0.04%) communities.
Membership percentiles (preliminary):
Memb. Policy 1% 5% 10% 25% 33% 50% 67% 75% 90% 95% 99%
All 0 1 1 1 1 1 4 8 40 110 859
"Join" 0 1 1 1 1 1 1 2 17 50 380
"Ask" 0 1 1 1 1 3 7 13 58 158 1253
(NB: we want to confirm that the Join and Ask to join stats are correct as previous analysis showed higher membership for open-membership sites, though that sample excluded the very largest G+ communities. It's possible sense is inverted. Spot checks say we're not
fouling this one up.)
