# FAQs

#### What is website visitor tracking?

Every day, there are visitors visiting your website who do not fill in a form or identify themselves. Many of these visitors are interested in your product, but for whatever reason are not ready to commit. Visitor tracking allows you to de-anonymize this traffic and take action, for example, to proactively reach out or start advertising to this group.

#### How does website visitor tracking work?

Sprouts partner, Clearbit, has a proprietary algorithm to map a wide range of company domains to IP addresses. Their machine learning algorithm continues working to identify and validate matches, to hundreds of millions of new data points each month, along with multiple signals from traffic patterns, geolocation, manual QA, and more. Thus, tracking visitors who are working from home is now possible as they have adapted to the new work-from-home-era

#### What function do we use to ensure IPs are encrypted?

Sprouts uses Java cipher service to encrypt IPs and the encryption algorithm is called `AES/CBC/PKCS5Padding`

In terms of security, AES/CBC/PKCS5Padding is considered to be more secure than MD5 and SHA. However, it is important to note that no cryptographic algorithm is completely secure. As computing power increases, it becomes possible to break even the most secure algorithms.

#### How can we track custom landing pages hidden behind ad campaigns? <a href="#inlineextension-how-can-we-track-custom-landing-pages-hidden-behind-a-d-campaigns" id="inlineextension-how-can-we-track-custom-landing-pages-hidden-behind-a-d-campaigns"></a>

There are multiple ways landing pages are created. Only a matter of configuration, and Sprouts can track them all provided the tracking snippet is triggered on these pages. Some examples of how this could be done -

1. <http://domain.com/path&utmparams=ad> - Sprouts can track such pages without any additional configuration on Sprouts as far as Sprouts tracking snippet is configured and traffic is received by Sprouts platform
2. <http://subdomain.domain.com/path&utmparams=ad> - Sprouts can track such pages, provided the [subdomain.domain.com](http://subdomain.domain.com/) is added to ‘Allowed domains’ in the Settings > Configuration > Website snippet tracking panel on Sprouts platform

A subdomain is a piece of additional information added to the beginning of a website's domain name. It allows websites to separate and organize content for a specific function from the rest of your website. In order to cater to tracking activity for our customers on their subdomains as well, we are allowing our users to configure the subdomains where they need tracking enabled.

#### How to check if the snippet is configured correctly?

To verify, open your website page with the installed snippet, and inspect the page using Ctrl+Shift+I (Cmd+Shift+I for Mac). In the Network tab, filter by 'pixel' AND 'autoCapture', and check its status. Unless it shows "5xx" it's correctly installed and operational.
