Is 6% views at "Scroll ratio 75%" a bad thing?
Is it a bad thing if only 6% of page views reach a scroll depth of 75%? In this article I explain how I assess scroll depth.
Various metrics can be used to assess the performance of a page:
Interaction rate: the percentage ratio of interaction with clickable elements on the page / views.
Interactions include clicks on image sliders, calculators, anchor navigation, internal promotions, etc.
Internal promotion click-through rate (the percentage ratio of internal promotion clicks / internal promotion views).
Internal promotion elements are image or text elements with one or more CTAs on the page that take the user to another topic.
The usual page metrics such as bounce rate, average time spent on site, and page views per session.
And, of course, scroll depth.

Scroll depth
If you look at scroll depth, you will notice that the percentage of page views per scroll depth mark usually decreases dramatically the longer a page is. The lower part of a page is seen by relatively few users. At first glance, this can be disappointing if you've just launched a new landing page at great expense.

As the creator of the page, you want as many users as possible to see as much of your beautiful page as possible. But is that really in the users' best interest?
Goals of content pages
The user comes to the page to pursue a goal. If they see a long content page and find their goal displayed in an element relatively high up on the page (e.g., an internal promotion element), they click on the element and are gone. They leave the page and move on. This is a success for the page and should be viewed positively. The page worked for this user. There are “central” content pages (hub pages) that are nothing more than places to navigate from and bring the user to their goal. However, the final landing page is also a content page for completing a task/goal. Therefore, you should keep the goal of the content page in mind when looking at the scroll depth.

You can therefore categorize content pages according to their goals (e.g., “distribution page” & “landing page”) and then see how the individual categories perform and compare pages within the categories.
However, a high percentage scroll depth, e.g., at the 75% scroll mark on a distribution page, would probably be considered rather disadvantageous, and you should think about the content here.
Recalculate scroll depth
However, you can also exclude from the calculation all those who have either already found and clicked on their target further up or who have left the page in some other way. That would be everyone...
... who clicked on an element on the page.
... bouncers (landed on the page, did not scroll, did not click, left the page again).
Note: You could also exclude from the calculation the page views of users who did not click on any content elements, did not scroll, and left the page via the navigation. However, for the sake of simplicity, I will leave this group out at this point.
This leaves only those users who scroll the page but leave the page without interacting after, for example, 25% or 50% scroll depth. Or who clicked on an element after reaching a corresponding scroll mark.
I would like to illustrate the idea using formulas. I calculate the scroll depth based on the page views and the corresponding scroll mark.
Formula “Scroll Ratio 25%” = Count for scroll mark 25 / page views * 100
To perform an adjusted calculation of the scroll ratio, I subtract the page views of “non-clickers” from the total page views.
Adjusted formula scroll ratio 25%: Count for scroll mark 25 / (page views – bouncers – sum of clicks on internal promotion elements between 0-25%) * 100
When you look at the scroll depth after the adjustment, the result looks much better. I do this exercise to show
That the page works (most users find what they are looking for at the top of the page and therefore do not need to scroll down very far).
To sharpen understanding of scroll tracking (it is not always desirable for users to scroll to the bottom of the page).
To show that content pages have different goals.
This exercise is expressly not intended to simply make key figures look “pretty.”

The takeaway
- Content pages have goals and can be categorized according to these, e.g., “distribution pages” and “landing pages” or corresponding categories. The categories can then be compared with each other, making it easier to identify potential for optimization (“Why do users click less on distribution page A than on distribution page B?”).
- Not every low scroll ratio is bad, and not every high scroll ratio is good. The scroll ratio should always be viewed in the context of the page's goal.
- An adjusted scroll ratio better illustrates what percentage of page views did not find the goal higher up OR simply enjoyed the page.
