8. Web Log Analytics
Web Analytics allows you to collect web server log
files and import them into your analytics platform for
viewing, analyzing, and reporting. It is recommended
for superior security and data protection.

9. Which web analytics vendors use
Web Log Analytics to collect data?
JavaScript Tracking or Web Log Analytics?

10. Use Web Log Analytics when:
• your organization handles great amounts of sensitive
data
• you need to track activity of a particular server
• you want to analyze historical data from your log files
• your website contains too many pages and you don’t
want to place JS tags on every single one of them
• you want to track users with JavaScript turned off

11. Let’s move to the differences
between JS Tracking and
Web Log Analytics
JavaScript Tracking or Web Log Analytics?

12. Event Tracking
JavaScript Tracking
• Can track events and user
interactions like page views
and downloads.
Web Log Analytics
• Events are not tracked in
http server logs, but it can
precisely track downloads

13. Single Page Tracking
JavaScript Tracking
• Can track single pages
accurately.
Web Log Analytics
• It may be challenging to
achieve with Log Analytics,
as the data provided by
logs may be hard for the
marketer or analyst to read.
They will only see the URLs
of API calls, which may not
mean anything.
JavaScript Tracking or Web Log Analytics?

14. Device Tracking
JavaScript Tracking
• Tracks page titles, browser
resolutions, and installed
plugins.
Web Log Analytics
• This is not the case with log
analytics, as the relevant
data is not available in the
server http log files.

15. Unique Visitor Tracking
JavaScript Tracking
• Uses both first-party
cookies and browser
fingerprint in order to
accurately identify unique
visitors.
Web Log Analytics
• Doesn’t use cookies,
therefore cannot identify
unique users. Log analytics
cannot accurately calculate
returning visitors, visitor
recency, number of visits to
conversion and other
metrics related to your
users' loyalty.

16. Data Transparency
JavaScript Tracking
• JS Tracking provides you
with clean and reliable
data.
Web Log Analytics
• Log analytics analyzes all
http server calls. There is
quite a bit of work required
to filter out URLs that are
not relevant (like calls from
monitoring systems or
single page app API calls).
JavaScript Tracking or Web Log Analytics?

17. Anchor URL Tracking
JavaScript Tracking
• Can easily track anchor
URLs.
Web Log Analytics
• Cannot track anchor URLs
(like https://piwik.pro/
contact/#contact-form):
the #contact-form part is
not passed to the server by
the browser.
JavaScript Tracking or Web Log Analytics?

18. Tag Implementation
JavaScript Tracking
• JS Tracking code must be
placed on every page of
your website.
Web Log Analytics
• Does not require tracking
code (JavaScript tag) on
the website.
JavaScript Tracking or Web Log Analytics?

19. Bandwidth Analytics
JavaScript Tracking
• Bandwidth usage cannot
be tracked, because the
information is not provided
by the web server to the
browser client.
Web Log Analytics
• It can also be used for
bandwidth analytics of how
much bandwidth each
website generates.
JavaScript Tracking or Web Log Analytics?

20. Historical Data Access
JavaScript Tracking
• You get access to data
collected only from the
moment of implementation
of your analytics software.
Web Log Analytics
• You can process historical
data even if you didn’t
previously have any
analytics system in place.
JavaScript Tracking or Web Log Analytics?

21. Download Tracking
JavaScript Tracking
• Downloads and other
events from the website
may not be registered if the
user has a slow connection
or JavaScript disabled.
Web Log Analytics
• Information from the http
server lets us reliably track
all downloads.
JavaScript Tracking or Web Log Analytics?

22. Ad Blocker Resistance
JavaScript Tracking
• It may be blocked by ad
blockers or other browser
plugins such as Ghostery.
Web Log Analytics
• Resistant to ad blockers
and tracks browsers with
disabled JavaScript - we
analyze data from the http
web server, so the log
analytics method always
knows about requests
made to the server.
JavaScript Tracking or Web Log Analytics?

23. Security
JavaScript Tracking
• Anyone who access your
server can essentially inject
any code into your website,
capture data from users that
leave it on the website, etc.
Moreover, JS Tracking requires
adding external files into the
website. This may not be
feasible for many
organizations due to data
security considerations.
Web Log Analytics
• The log analytics server
can be separated from
the website for better
security. Banks,
healthcare and other
data-sensitive industries
take advantage of this
capability.
