12. Page Sequence Analysis
12
• Understand the sequence the users follow to reach a certain page
• The sequences can be modified to be before or after and to also include events
Landing

Page

Page

C
Contact

13. Custom Funnels
13
• Get unsampled custom funnels with added
benefits
- No Backfilling
- Historical Information
- Apply filters
- Unlimited steps
• Both open and closed funnels

14. 14
Using Flatten
Sample Data Set
• BigQuery uses repeated (nested) fields to
store data
• While querying nested data, BigQuery
automatically flattens the table data
• However, when dealing with more than one
repeated field, we need to explicitly use
FLATTEN on the table

15. 15
Using Flatten
While querying data using
below query,
BigQuery flattens the data
automatically

16. 16
Using Flatten
• However, running the query:
• It shows the error:
• Use FLATTEN as per shown in below query to fetch proper results:

17. 17
Useful Functions
• BigQuery functions are more or less similar in nature to that of regular SQL
• However, there are some functions which act differently to an extent
COUNT([DISTINCT] field [, n]) REGEXP_MATCH('str', 'reg_exp')
EXACT_COUNT_DISTINCT(field) REGEXP_REPLACE('orig_str', 'reg_exp', 'replace_str')
GROUP_CONCAT('str' [, separator]) DATEDIFF(<timestamp1>,<timestamp2>)
FIRST(expr), LAST(field) DAY/MONTH/HOUR/MINUTE(<timestamp>)
STRING(numeric_expr),
INTEGER(expr)
TABLE_DATE_RANGE(prefix, timestamp1, timestamp
2)
CONCAT('str1', 'str2', '...') ROW_NUMBER()
DATE(<timestamp>) RANK()

18. Best Practices
18
✓ Start by sketching the expected result
before writing your query
✓ Only select the relevant fields; The
more fields you select, the more data
it has to process and eventually
leading to more time and cost
✓ Avoid using functions as fields when
possible and prefer specific times and
dates, to allow caching
✓ Use intermediate tables for commonly
used subqueries
✓ Use caching whenever possible,
reduce execution time and costing
✓ Format and comment your queries, it
will be easier to read, understand and
debug
✓ Statements are not case-sensitive but
it’s a best practice to capitalize
