Landing Page的要點有：精簡形容服務、使用幾大好處、使用示意、使用者見證、引誘註冊/購買和免費註冊/退款

保證


index > post (w/o login ) > landing page










A/B testing是在這裏第一次聽到的名詞，用來比較哪一種UI/作法/model效益更大，有了好的測量工具可以讓我們快

Q&A


Acquisition, Activation, Retention, Referral, Revenue

• Acquisition : 從多個管道曝光

大多數人對於增進 Acquisition 的想法是下廣告，或者 SEO。這叫 Acquisition。

增強 Acquisition 的手法不外乎是經營粉絲團，下 FB 廣告，寫很好的 FB 廣告或一般廣告流量，改善 open graph 上的標題與資訊，搜尋引擎上的文案。

• Activation : 註冊帳號使用第一次

1. 消費者不知道你提供什麼服務，不願意註冊
2. 消費者不懂 How it works，不願意註冊
3. 消費者有一些疑問，不知道怎麼樣繼續詢問下去，就不願意註冊
4. 消費者不知道你的來歷，註冊了帳號卻不願意把信用卡資料填上去。

這就是設計一個 Landing Page 的重要性。Landing Page 是「使用者著陸的第一個頁面」。它可以是首頁，或者是 Referral 頁面，或者是搜尋引擎給到的第一個頁面。

• Retention : 留住客戶繼續用很多次

有時候你註冊外國網站 SaaS，幾天後 Founder 有時候會親自寫信給你。（或者機器偽裝 Founder 寫信給你）。

目的是要查看使用者為什麼卡住了，為什麼不繼續用。或者有什麼疑慮我們可以協助排除。

付錢的 Retention，則是比如說提供 Daily new deal promo，或者是 Loyalty program....etc.作一些互惠的活動，來保持使用者繼續回訪。

• Referral : 介紹朋友也一起用這個 Service

Referral Program 當然不只有設計 Referral Code 這麼膚淺。好的 Referral 如 Airbnb 與 Dropbox 都有相當好的循環獎勵設計。這也是位什麼他們的 user base 瘋狂成長。

比如說 Airbnb 在 Referral Landing, 獎勵, 與介紹就做的相當好。Dropbox 則是擅長辦競賽以及 online quest。

• Revenue : 從客戶上賺到錢。

IN RAILS APP

gem 'airbrake'

create file config / initializers / errbit.Rb


copy paste the the info you got in Errbit > Apps

something likes

Airbrake.configure do |config|
 config.api_key = ENV['ERRBIT_API_KEY']
 config.host    = ENV['ERRBIT_HOST']
 config.port    = 80
 config.secure  = config.port == 443
 config.environment_name = Rails.env.production? ? `hostname` : Rails.env
end

run bundle install after setting down above.

then,

rake airbrake:test

adding

ERRBIT_API_KEY ERRBIT_HOST to heroku

heroku config:set ERRBIT_HOST= 

heroku config:set ERRBIT_API_KEY=

heroku run bundle exec rake airbrake:test

heroku  rake geocode:all CLASS=YourModel SLEEP=0.25 BATCH=100

next next step 

http://stackoverflow.com/questions/23012404/geocoder-ruby-gem-on-demand

I create pull request based on this answer and now you can use batch in geocoder:

rake geocode:all CLASS=YourModel SLEEP=0.25 BATCH=100

I would use this solution for large database, i take it from geocoder gem rake task: You can refine this for your needs. Some example create rake task:

namespace :geocode_my_data do
  desc "Geocode all objects in my databse."
  task all: :environment do
  klass = User
    klass.where(geocoded: false).find_each(limit: 100) do |obj|
      obj.geocode; obj.save
    end
  end
end

$> rake geocode_my_data:all

Used below code and put it into my lib/tasks folder as geocode_my_data.rake To run:

rake geocode:all CLASS=YourModel

Works great!

namespace :geocode_my_data do
  desc "Geocode all objects without coordinates."
  task :all => :environment do
    class_name = ENV['CLASS'] || ENV['class']
    sleep_timer = ENV['SLEEP'] || ENV['sleep']
    raise "Please specify a CLASS (model)" unless class_name
    klass = class_from_string(class_name)

klass.not_geocoded.find_each(batch_size: 100) do |obj|
      obj.geocode; obj.save
      sleep(sleep_timer.to_f) unless sleep_timer.nil?
    end
  end
end

##
# Get a class object from the string given in the shell environment.
# Similar to ActiveSupport's +constantize+ method.
#
def class_from_string(class_name)
  parts = class_name.split("::")
  constant = Object
  parts.each do |part|
    constant = constant.const_get(part)
  end
  constant
end
