Speed Index vs. above fold animations
Let's say a website has some introductory animation above the fold, eg. an image fades in, then a heading slides in, etc. Normally those elements would appear at some moment but now they are delayed by the animation duration. Does this affect Speed Index?
Thanks |

Does this affect Speed Index? If there's a large enough visual change, which it does sound like, then yes. |

Does this affect Speed Index? Yes, thank you. In the meanwhile I've set up a test to verify this, just haven't got to answering my own question here yet: Test page without animation: http://animations-speed-index.previewize...tions.html Test result: http://www.webpagetest.org/result/150720...e5d152571/ Test page with animation: http://animations-speed-index.previewize...ons-1.html Test result: http://www.webpagetest.org/result/150720...00c48bfe1/ There are 3 animations taking 2 seconds together, which almost doubled the speed index result. |
