Gattica is an easy to use Gem for getting data from the Google Analytics API.
How to export Google Analytics data using Ruby (Links to my blog post on Seer Interactive)
Here are bare basics to get you up and running.
Add Gattica to your Gemfile
gem 'gattica', :git => 'git://github.com/chrisle/gattica.git'
Don't forget to bundle install:
$ bundle install
Login, get a list of accounts, pick an account, and get data:
# Include the gem
require 'gattica'
# Login
ga = Gattica.new({
:email => 'email@gmail.com',
:password => 'password'
})
# Get a list of accounts
accounts = ga.accounts
# Choose the first account
ga.profile_id = accounts.first.profile_id
# Get the data
data = ga.get({
:start_date => '2011-01-01',
:end_date => '2011-04-01',
:dimensions => ['month', 'year'],
:metrics => ['visits', 'bounces'],
})
# Show the data
puts data.inspect
ga = Gattica.new({ :email => 'email@gmail.com', :password => 'password' })
puts ga.token # => returns a big alpha-numeric string
# Retrieve a list of accounts
accounts = ga.accounts
# Show information about accounts
puts "---------------------------------"
puts "Available profiles: " + accounts.count.to_s
accounts.each do |account|
puts " --> " + account.title
puts " last updated: " + account.updated.inspect
puts " web property: " + account.web_property_id
puts " profile id: " + account.profile_id.inspect
puts " goals: " + account.goals.count.inspect
end
# Tell Gattica to query profile ID 5555555
ga.profile_id = 5555555
The Get method will get data from Google Analytics and return Gattica::DataSet type.
Here's an example:
# Get the number of visitors by month from Jan 1st to April 1st.
data = ga.get({
:start_date => '2011-01-01',
:end_date => '2011-04-01',
:dimensions => ['month', 'year'],
:metrics => ['visitors']
})
Here are some additional examples that illustrate different things you can do with dimensions and metrics.
# Sorting by number of visits in descending order (most visits at the top)
data = ga.get({
:start_date => '2011-01-01',
:end_date => '2011-04-01',
:dimensions => ['month', 'year'],
:metrics => ['visits']
:sort => ['-visits'],
})
# Limit the number of results to 25.
data = ga.get({
:start_date => '2011-01-01',
:end_date => '2011-04-01',
:dimensions => ['month', 'year'],
:metrics => ['visits']
:max_results => 25
})
my_hash = data.to_h['points']
# =>
# [{
# "xml" => "<entry gd:etag=\"W/".... </entry>",
# "id" => "http://www.google.com/analytics/feeds/data?...",
# "updated" => Thu, 31 Mar 2011 17:00:00 -0700,
# "title" => "ga:month=01 | ga:year=2011",
# "dimensions" => [{:month=>"01"}, {:year=>"2011"}],
# "metrics" => [{:visitors=>6}]
# },
# {
# "xml" => ...
# "id" => ...
# "updated" => ...
# ...
# }]
# Return data as a json string. (Useful for NoSQL databases)
my_json = data.to_h['points'].to_json
# =>
# "[{
# \"xml\":\"<entry> .... </entry>\",
# \"id\":\"http://www.google.com/analytics/feeds/data? ...",
# \"updated\":\"2011-03-31T17:00:00-07:00\",
# \"title\":\"ga:month=01 | ga:year=2011\",
# \"dimensions\":[{\"month\":\"01\"},{\"year\":\"2011\"}],
# \"metrics\":[{\"visitors\":6}]
# },
# {
# \"xml\":\"<entry> .... </entry>\",
# \"id\":\"http://www.google.com/analytics/feeds/data? ...",
# ...
# }]"
# Return the data in CSV format. (Useful for using in Excel.)
# Short CSV will only return your dimensions and metrics:
short_csv = data.to_csv(:short)
# => "month,year,visitors\n\n01,2011, ...."
# Long CSV will get you a few additional columns:
long_csv = data.to_csv
# => "id,updated,title,month,year,visitors\n\nhttp:// ..."
# You can work directly with the 'point' method to return data.
data.points.each do |data_point|
month = data_point.dimensions.detect { |dim| dim.key == :month }.value
year = data_point.dimensions.detect { |dim| dim.key == :year }.value
visitors = data_point.metrics.detect { |metric| metric.key == :visitors }.value
puts "#{month}/#{year} got #{visitors} visitors"
end
# =>
# 01/2011 got 34552 visitors
# 02/2011 got 36732 visitors
# 03/2011 got 45642 visitors
# 04/2011 got 44456 visitors

# Get all the profiles that have goals
profiles_with_goals = accounts.select { |account| account.goals.count > 0 }
# =>
# [{
# "id" => "http://www.google.com/analytics/feeds/accounts/ga:...",
# "updated" => Mon, 16 May 2011 16:40:30 -0700,
# "title" => "Profile Title",
# "table_id" => "ga:123456",
# "account_id" => 123456,
# "account_name" => "Account name",
# "profile_id" => 123456,
# "web_property_id" => "UA-123456-3",
# "goals"=>[{
# :active => "true",
# :name => "Goal name",
# :number => 1,
# :value => 0.0
# }]
# },
# {
# "id" => "http://www.google.com/analytics/feeds/accounts/ga:...",
# "updated" => Mon, 16 May 2011 16:40:30 -0700,
# "title" => "Profile Title",
# ...
# }]
# Get all the segments that are available to you
segments = ga.segments
# Segments with negative gaid are default segments from Google. Segments
# with positive gaid numbers are custom segments that you created.
# =>
# [{
# "id" => "gaid::-1",
# "name" => "All Visits",
# "definition" => " "
# },
# {
# "id" => "gaid::-2",
# "name" => "New Visitors",
# "definition" => "ga:visitorType==New Visitor"
# },
# {
# "id" => ... # more default segments
# "name" => ...
# "definition" => ...
# },
# {
# "id" => "gaid::12345678",
# "name" => "Name of segment",
# "definition" => "ga:keyword=...."
# },
# {
# "id" => ... # more custom segments
# "name" => ...
# "definition" => ...
# }]
# Return visits and bounces for mobile traffic
# (Google's default user segment gaid::-11)
mobile_traffic = ga.get({
:start_date => '2011-01-01',
:end_date => '2011-02-01',
:dimensions => ['month', 'year'],
:metrics => ['visits', 'bounces'],
:segment => ['gaid::-11']
})
Filters are boolean expressions in strings. Here's an example of an equality:
# Filter by Firefox users
firefox_users = ga.get({
:start_date => '2010-01-01',
:end_date => '2011-01-01',
:dimensions => ['month', 'year'],
:metrics => ['visits', 'bounces'],
:filters => ['browser == Firefox']
})
Here's an example of greater-than:
# Filter where visits is >= 10000
lots_of_visits = ga.get({
:start_date => '2010-01-01',
:end_date => '2011-02-01',
:dimensions => ['month', 'year'],
:metrics => ['visits', 'bounces'],
:filters => ['visits >= 10000']
})
Multiple filters is an array. Currently, they are only joined by 'AND'.
# Firefox users and visits >= 10000
firefox_users_with_many_pageviews = ga.get({
:start_date => '2010-01-01',
:end_date => '2011-02-01',
:dimensions => ['month', 'year'],
:metrics => ['visits', 'bounces'],
:filters => ['browser == Firefox', 'visits >= 10000']
})
Output the top 25 keywords that drove traffic to your website in the first quarter of 2011.
# Get the top 25 keywords that drove traffic
data = ga.get({
:start_date => '2011-01-01',
:end_date => '2011-04-01',
:dimensions => ['keyword'],
:metrics => ['visits'],
:sort => ['-visits'],
:max_results => 25
})
# Output our results
data.points.each do |data_point|
kw = data_point.dimensions.detect { |dim| dim.key == :keyword }.value
visits = data_point.metrics.detect { |metric| metric.key == :visits }.value
puts "#{visits} visits => '#{kw}'"
end
# =>
# 19667 visits => '(not set)'
# 1677 visits => 'keyword 1'
# 178 visits => 'keyword 2'
# 165 visits => 'keyword 3'
# 161 visits => 'keyword 4'
# 112 visits => 'keyword 5'
# 105 visits => 'seo company reviews'
# ...
If you have a lot of profiles in your account (like 1000+ profiles) querying for accounts may take over a minute. Net::HTTP will timeout and an exception will be raised.
To avoid this, specify a timeout when you instantiate the Gattica object:
ga = Gattica.new({
:email => 'email@gmail.com',
:password => 'password',
:timeout => 600 # Set timeout for 10 minutes!
})
The default timeout is 300 seconds (5 minutes). Change the default in: lib/gattica/settings.rb
For reference 1000 profiles with 2-5 goals each takes around 90-120 seconds.
You can reuse an older session if you still have the token string. Google recommends doing this to avoid authenticating over and over.
my_token = ga.token # => 'DSasdf94...'
# Sometime later, you can initialize Gattica with the same token
ga = Gattica.new({ :token => my_token })
If your token times out, you will need to re-authenticate.
Google expects a special header in all HTTP requests called 'Authorization'. Gattica handles this header automatically. If you want to specify your own you can do that when you instantiate Gattica:
ga = Gattica.new({
:token => 'DSasdf94...',
:headers => {'My-Special-Header':'my_custom_value'}
})
