Google has come up with a pilot study, testing slow label signs in mobile search results. Earlier in February, Google experimented with Red Slow Labels, this time they switched the “ Slow to Load” sign from Red to Yellow in color.
The Android Soul Blog posted screenshots of mobile search results of Google testing “slow to load” labels, with pictures of a little yellow warning sign next to loaded results.
Being heavy files, Youtube Videos can be slow to load, hence they are marked with a warning sign as displayed in Android devices.
When approached Google for a comment, they justified their experimentative nature behind converting warning sign from Red to Yellow.
