So, if you have, when someone imports if on average they send invites to 100 people.
那么假設(shè)每個人平均發(fā)送100個邀請鏈接
Sorry doing that wrong, let's say 100 people get an invite per person who imports.
抱歉，錯了假設(shè)每個人平均邀請了100個人
And then of those 10% click. That gets you to 10.
其中10%的人點(diǎn)擊了鏈接，那么就剩下10個人了
And then, of those, let's say, 50% sign up. That gets you to 5.
然后我們假設(shè)有50%的人注冊了，還剩下5個人
And then, of those, only 10 to 20% actually, subsequently import.
接著這5個人中的10%到20%會繼續(xù)導(dǎo)入其聯(lián)系人
You're gonna be at a point where you're at 0.5 to 1 as your K factor.
結(jié)果就是0.5到1個人，那么增殖系數(shù)就在0.5到1之間
And you're gonna not be viral.
這就不能稱為病毒式傳播
So, a lot of things like Viddy are very good at pumping, or were very good at pumping out stories.
視頻分享應(yīng)用Viddy現(xiàn)在，或者說以前對病毒式營銷就很在行
They got the k factor over one, and it's perfectly doable to get the k factor over one,
他們的增殖系數(shù)大于1讓增殖系數(shù)達(dá)到1以上是完全可以做到的
but if you have something that doesn't have high retention on the back end then it doesn't really matter.
所以如果你的用戶存留不高病毒式營銷就意義不大
So, you should look at your invite flow and say, what is my equivalent to import?
看看你的整個邀請流程需要導(dǎo)入哪些聯(lián)系人
How many people, per import, are invites sent to?
每個用戶給多少人發(fā)邀請呢？
How many of those receive clicks?
多少人會打開鏈接呢？
How many of those convert to my site? How many of those then import?
多少人會在我的網(wǎng)站注冊，多少人會再去導(dǎo)入他們的聯(lián)系人
To get an idea of your k factor.
據(jù)此，就可以算出自己的增殖系數(shù)
But the really, important thing is still to think about retention, and not to think about virality.
當(dāng)然，首先要考慮的還是用戶存留而不是病毒營銷
And only do this after you have a large number of people retained on your product per person who signs up.
只有當(dāng)注冊的人中很大一部分都能留在你的產(chǎn)品上的時候，再考慮病毒營銷
So, couple more things we were gonna touch on.
好，我們還要講點(diǎn)別的
SEO, email, SMS and push notifications.
搜索引擎優(yōu)化，電子郵件，短信和推送通知
