What are some of the most asked questions about the Leadfeeder Tracker?

We answer a lot of questions every day, but these are what we hear the most often!

Q: What is the Leadfeeder Tracker?

In simple terms, the Leadfeeder Tracker is a small piece of javascript that is placed on your website that allows Leadfeeder to identify visits.

This type of script can also be referred to as a tag, tracking pixel, or script. We call it a script, Google Tag Manager calls it a tag and Facebook calls it pixel. All meaning a piece of code that's inserted on the website.

Q: Will the Leadfeeder Tracker slow down my site?

The Leadfeeder Tracker shouldn't have any impact on your site speed. The tracker is an asynchronous script, meaning it doesn't have to load before your site loads. It works in the background making page loading your priority.

The tracker script is delivered from the AWS Cloudfront content delivery network, which ensures that no matter where the visits come from the script is always loaded close to them with minimal latency. Cloudfront has over 200 edge locations all over the world, including, most likely one near your visitor.

Q: With many web browsers leaning to protect privacy by blocking cookies and tracking how will that impact the Leadfeeder Tracker?

The majority of these theoretical changes are in regards to 3rd party cookies. Browsers blocking 3rd party cookies in the future has no effect on how Leadfeeder operates since we don't use them.

Though Dealfront uses 1st party cookies, we rely mainly on a completely different type of technology which means to us 'no cookies, no problem'.

Even if all cookies were blocked we would still be able to ID companies visiting your site.

Q: Why is the Leadfeeder Tracker ‘blocked’ on my site?

The Tracker may be blocked by a 'Content Security Policy' on your site. Learn more about how to get this fixed here.

Q: How do I know the Leadfeeder Tracker is on my site and working?

If you have just installed the tracker on your site give it at least an hour to begin tracking. If you have an unpaid account you will need to wait for 24 hours for the update. At that point, you can check your status in your Settings > Company > Website Tracker. You can also see some tips to check your installation here if you want to see if the script is on the site properly.

The tracker will temporarily deactivate if the website has not received any visits from identifiable company for 48 hours, it will re-fire once an identifiable visit lands on the site.

If you have lower amount of Leadfeeder identified companies, it might be that there has been a lower amount of companies visiting and instead more ISP visits.

Q: Why do I need the tracker, I have Google Analytics connected?

As of Feb 4, 2020, at 8 am San Francisco time (Pacific Time) Google Analytics stopped providing information required for visit identification. Any visits seen after that time can not be identified until the Leadfeeder Tracker is/was installed and updated.

Q: Is the Leadfeeder Tracker GDPR compliant? IP - anonymisation

Yes, it is. You can also turn IP-address anonymisation on in your Leadfeeder Tracker settings if desired. IP address anonymisation does not impact company recognition (unlike Google Analytics) nor does it slow down the recognition. However, we won't be able to later debug based on IP addresses anymore, since we won't have them.

IP addresses are anonymised by dropping the last octet. As an example, IP address would become This anonymisation makes it impossible to connect outside IP address information later, preventing singling out an individual visitor.

Q: What information do I see in Leadfeeder once I install the Leadfeeder Tracker?

For each visit from an identified company you will see:

  • Time and Date of visit

  • Source and Medium

  • Number of pages visited

  • Pages visited (Title, URL, and Length of the page visits)

  • Visitor ID number

  • The total length of visit

Q: Should I also connect Google Analytics with Dealfront?

We recommend that you do. Although it isn’t identifying companies it may enhance some information as time goes on such as keyword data and query information.

Q: Does the tracker work on single-page applications/sites?

Yes, the tracker works on SPAs. The Leadfeeder Tracker does not rely on a page-load but it tracks changes in the page URL to identify pageviews. If your SPA changes the page URL without a page-load, the new page URL will be identified as a new pageview by default.

Learn more about SPA tracking here.

Note: This is the default tracker behaviour after May 2022. If you signed up before and need this feature, please reach out to support and we’ll be happy to help!

Q: Are there any limitations on installing the tracker on a desktop app instead of a website?

The “webpages” in such an app might be loaded by a different browser view than https or http protocol, which we need to do proper tracking. It maybe could work if it is just a website “packed” into an app with “webpages” loaded only by http or https protocol.

Q: How do I install the Leadfeeder Tracker?

We have detailed instructions on how to install the tracker here!

Q: Can I install the Leadfeeder Tracker on any website?

If you can add custom JavaScript to your site either directly, via Google Tag Manager, or with a plugin, the Leadfeeder Tracker should be able to be installed. If you can’t add any custom scripts or Google Tag Manager you may want to talk to your web builder or CMS, adding scripts is something you want to do!

Q: Does loading the tracker twice on my website = more data?

You should never load the tracker on your website more than once as it will skew the numbers we will give you regarding your identified companies and visits (you will see more). How can you check if you are loading the tracker only once? Add this into developer tools/console: => s.src)

Watch if it shows the tracker twice:

If you see it loaded twice, you need to fix your code to load it only once.
