Image heatmap


The Image heatmap question type presents respondents with an image and asks them to select specific areas as their response. Respondents can also leave optional comments on their selections.

Some common use cases include asking respondents to identify areas they like, dislike, find clear, or find confusing when evaluating branding assets, digital advertisements, packaging designs, product concepts, shelf layouts, and more.

If you would like to gather similar feedback on text instead, check out our text highlighter questions.

Respondent view

Conjointly offers three types of image heatmap questions:

  • Dots and Brushes both allow multiple selections across the image.

Dots highlight type

Dots allow pinpoint accuracy with an optional text box per dot, ideal for detailed feedback on specific elements.

Brushes highlight type

Brushes allow quick highlighting of larger areas with an optional text box per colour, ideal for overall design evaluations.

  • First click works similarly to Dots but limits respondents to a single, non-editable marker. Use it to test which element first captures attention.

Image heatmap question outputs

An image heatmap question produces the following outputs:

  • Heatmaps for areas that were selected by participants most often. The heatmaps are separated according to the dot/stroke types specified.
  • AI summaries of open-ended text responses that outlines the distribution of sentiments and key themes in respondent comments.
  • The number of participants who saw the question.

Dots highlight type

The dots highlight type output shows the specific areas respondents clicked, with darker regions resembling more clicks.

Click on any area on the heatmaps, and you can view the responses for that particular area.

It also provides descriptive statistics, including mean, standard deviation, median, minimum, maximum, and mode for each feedback type.

Brushes highlight type

The brushes highlight type output shows the entire areas respondents shaded, with darker regions resembling a higher frequency of overlapping.

The First click output shares the same structure as Dots, covering the specific elements respondents clicked, AI summaries, and descriptive statistics. The key distinction is that each respondent contributes a single marker only, representing the first element they selected.

Remove participants directly

Once you see a nonsensical response, you can directly remove it from the outputs. Click on Show all responses, then hover your mouse over the response you want to remove, right-click, and click on Mark as a bad response and exclude from analysis .

For all question types, you can set the minimum and maximum number of characters required in comments using the From and To fields next to the possible number of characters in comment. By default, both are set to Any, allowing respondents to skip comments entirely.

Setting up the monadic view of image heatmap questions

The Monadic Test is an effective and efficient way to survey respondents with multiple image heatmap questions, which allows focused testing of visuals. Check out our comprehensive guide to setting monadic image heatmap questions.

Please note that when two images are included as a single stimulus, the heatmap is generated based on the first image.

The monadic image heatmap questions generate a summary table of outputs for all questions within the block, and outputs for individual questions.
