How to Track Visitors Based on Scroll Level?

The level of attention one gives to something reflects its significance to them. Page scrolling is a crucial indicator of visitor interest relevance. 

For instance, if you’re tracking the scroll depth on your website’s product pages, you can identify that visitors who scrolled through 75% of the pages were more likely to make a purchase.

You can tap into this insight with VWO’s scroll tracking feature that allows you to track vertical and horizontal page scrolls both by pixels and percentage. You just need to create a metric with the Page unload event and configure a scroll option as the event property. This typically means tracking the visitors who leave the page without necessarily reaching or exceeding the specified scrolling level.

To achieve this, go to Data360 > Metrics > Create and perform the following steps:

1. Enter a name for the metric in the Metric Name field.
2. From the Event you want to track for this metric dropdown, select Page unload.
3. Click on + where, which, by default, will populate the Page URL option in the dropdown.
4. If required, you can specify the URL match conditions or select a page from the Page section in the URL match condition dropdown.
5. Now, define the scrolling level (value in percentage or pixel) within which a visitor unloads the page. Click on + and where, and select any of the following scroll scaling options based on your requirement:

6. Specify the matching condition in the adjacent dropdown and enter the corresponding value in the subsequent field.
7. If you want to filter out the fast scrollers, you can add in the duration factor. For example, while deeper scrolls generally translate to higher conversion, people who scroll down to 80% in about 5 seconds are probably not looking deeper into the page. Maybe the page doesn’t match their preference. To do this, click on + and where, and select Duration in seconds.
8. Specify the matching condition in the adjacent dropdown and enter the corresponding value in the subsequent field as shown below:
   
9. In the Metric will calculate section, select Unique visitors to count the unique visitors who satiate the scroll level and duration stipulation. 

If you require the count of the occurrences where a visitor has satisfied the scroll level and duration stipulation, select Event totals.

To get an aggregated value for the scroll level of a visitor across all events, you can select Value of an event property. To do so, click on this dropdown and select an appropriate option from the following: 

• • First value - Gives the value of the scroll level during the first instance of the visitors, who satiate the stipulated conditions for the metric.
  • Last value - Gives the value of the scroll level during the last instance of the visitors, who satiate the stipulated conditions for the metric.
  • Sum - Gives the cumulative value of the scroll levels across all the instances of the visitors who satiate the stipulated conditions for the metric.
  • Average - Gives the average value of the scroll levels across all the instances of the visitors who satiate the stipulated conditions for the metric.
  • Maximum value - Gives the maximum value of the scroll level reached among all the instances in which the visitor satisfies the stipulated conditions for the metric.
  • Minimum value - Gives the minimum value of the scroll level reached by the visitors among all the occurrences in which the visitor satisfies the stipulated conditions for the metric.

10. You can choose to add a description for easier reference by clicking on the Add description link.
11. Click Create.

Now, you need to use this metric in your campaigns (A/B test, Split test, Multivariate test, or Personalize) to track the visitors based on the scroll level on those campaign pages.
