Hey, looks pretty good, just want to let you know you can leave comments in the code
not only using – but also
/*
like this
*/ for multi-line commenting! Might be useful to put your answers into the text as well, to help properly gauge your queries’ functionality

For example; here is my comment-infested version

select 1 as question;
/How many campaigns and sources does CoolTShirts use?
Which source is used for each campaign?/

select * from page_visits limit 20;
select count(distinct utm_campaign),
count(distinct utm_source)
from page_visits;
select utm_campaign, utm_source
from page_visits
group by 1;
– eight campaigns feuled by six sources
– interwoven relationships, except for
– newsletter( and retargeting?), which
– which is(/are) primarily sourced by email
– also, paid search is likely google only

select 2 as question;
/What pages are on the CoolTShirts website?/

select count(distinct page_name) from page_visits;
– four pages on the website

select 3 as question;
/How many first touches is each campaign responsible for?/

WITH first_touch AS (
SELECT user_id,
MIN(timestamp) as first_touch_at
FROM page_visits
GROUP BY user_id )
SELECT pv.utm_campaign,
count(ft.first_touch_at) as first_touch_count
FROM first_touch ft
JOIN page_visits pv
ON ft.user_id = pv.user_id
AND ft.first_touch_at = pv.timestamp
group by 1
order by 2 desc;
– campaign and corresp. # of first touches;

– the following queries create tables showing percentage

– USERS WITH LAST TIMESTAMP ON PURCHASE PAGE:
– * weekly newletter
– * retargetting ad
– * retargetting campaign

– THE FOLLOWING QUERY SHOWS SOURCING OF EACH CAMPAIGN:

round(sum(case when utm_source like ‘google’
then 1 else 0 end) , 3) as ‘google’,
round(sum(case when utm_source like ‘medium’

round(sum(case when utm_source like ‘nytimes’
then 1 else 0 end), 3) as ‘nytimes’
from page_visits
group by 1)
select * from campbysource limit 100;

– SINCE email and facebook are the sole sources to the top three
– campaigns, which account for ~75% of user purchases, they should
– be the focal points of future investments;
