5 Second Test allows website owners to upload images that will be reviewed by random Internet users. Users view the image for just five seconds then click on the screen to indicate areas of the images that caught their attention. Using text fields provided on the screen, they describe what they saw on the places they clicked. This is a free service. 5 Second Test is useful for understanding users’ first impressions of your site or any piece of creative you have. You’ll need to review others’ sites in exchange for your review.
