A slow loading website can cause serious distress to an entrepreneur. A well optimized website is critical to the success of your business.
Whether it be online banking or shopping, most of us want our user experience (UX) with a website to be flawless and enjoyable as possible. Unfortunately, this is not always the case.
Many of us have become accustomed to using various websites every day for a multitude of reasons.
Interested in user experience, Cyber Duck UX Agency created three websites with numerous issues which 1,100 participants tested, to establish which website issues cause users the most stress as measured by their blood pressure levels.
Cyber Duck UX Agency found that slow loading pages cause website users the most stress as average blood pressure levels jumped from 111 mm Hg to 134 mm Hg. This led to an astonishing increase of 21% in blood pressure levels.
| Website ‘issues’ which cause users most stress! | ||||
| Rank | Website Issue | Average Blood Pressure (mm Hg) Before Dealing with Website Issue | Average Blood Pressure (mm Hg) After Dealing with Website Issue | % Change (from Before to After) |
| 1. | Slow loading pages | 111 | 134 | 21% |
| 2. | Multiple pop-ups | 108 | 130 | 20% |
| 3. | Auto-play music | 106 | 127 | 20% |
| 4. | Broken pages (i.e. 404 Error) | 107 | 125 | 17% |
| 5. | Auto-play videos | 104 | 121 | 16% |
| 6. | Non-clickable call-to-action buttons | 105 | 120 | 14% |
| 7. | Hard to read fonts | 104 | 118 | 13% |
| 8. | Images not loading | 101 | 113 | 12% |
| 9. | Multiple image sliders | 99 | 109 | 10% |
| 10. | Disorienting animations | 102 | 107 | 5% |
| 110 participants were assigned for each website issue category. Systolic (mm Hg) blood pressure readings used for study. | ||||
The average page load times of the websites used in the study were between 8.8 – 10.5 seconds -participants used words such as ‘frustrating’ and ‘excruciating’ to describe the websites’ page load speeds. Participants felt anything above five seconds for a page load time is ‘inconvenient’ and ‘unacceptable’.
Multiple pop-ups are in second position as they caused participants’ blood pressures to rise from 108 mm Hg to 130 mm Hg.
The pop-ups participants saw during the experiment included newsletter subscriptions, discount codes, sale awareness and trial offer pop-ups. Participants stated that the use of multiple pop-ups was ‘annoying’ and ‘unnecessary’.
In third place is auto-play music as participants’ blood pressure elevated by an average of 20%, from 106 mm Hg to 127 mm Hg. Participants thought the unwelcome blaring of auto-play music on the websites was ‘infuriating’ and ‘disruptive’.
In comparison, auto-play videos fared better in fifth place as participants’ blood pressure surged from 104 mm Hg to 121 mm Hg, a 16% increase. Even though participants stated that auto-play videos were ‘distracting’, they said it was easier for them to spot and turn off the source of the sound compared to auto-play music.
Interestingly, in seventh position are the websites hard to read fonts which led to a 13% rise in participants’ blood pressure levels, from 104 mm Hg to 118 mm Hg. Participants thought the fonts on the website were ‘unwelcoming’ and ‘inconsiderate’.
On the other end in tenth place, participants took the least issue with disorienting animations on the websites with average blood pressure levels changing from 102 mm Hg to 107 mm Hg – only a 5% increase.
Slightly above disorienting animations is multiple image sliders, which rank ninth. Within the study, there were nine image sliders (also known as carousels) per website – the use of this many image sliders elevated the blood pressure of participants from 99 mm Hg to 109 mm Hg.
Participants said any more than three image sliders on a website page are ‘excessive’ and ‘oversaturated’.
