My initial instinct was to focus on the "loading" part of the RAIL model he described. I suspected that the histogram-based comparisons used in Speed Index's visual progress calculations could lead to some issues see the examples in the slide deck below for a gory exploration of this aspect.
I was annoyed by the fact that visual jitter caused by layout instability, weird ad behavior or carousel elements, etc.
I spent some time working out the math, and finding a way to address this issue in the computation of visual progress.
Above the fold
Fortunately, I found colleagues Karan at first, Clark and Matthew later on who were also interested in this topic, so we kept taking stabs at it whenever we found time. I reached out to Pat and it started a collaboration that ended up leading to some cool insights.
What we have developed is Perceptual Speed Index PSI , a novel metric that measures the above-the-fold visual performance of a webpage, while accounting for the layout stability. The code is open source , so you can go play with it if you like.
Some key take-aways: While SI focuses on addressing the question "did most of the webpage above-fold content load quickly? If the webpage shows layout stability problems like when an ad pops up and pushes the entire content down , PSI will be large.
SI typically ignores the fact that layout was thrashing.
Both are valid but different philosophical views of the same problem. SI and PSI are complementary measures of above-the-fold visual quality of experience of a webpage.
This means most of these webpages aren't visually jittery. It's free! Treating the visual QoE quality of experience measurement as a video- or multiple image frame- based problem allows multiple web delivery modes desktop web, mobile web, native app to be handled in a coherent, unified manner. I particularly like this aspect. Parting thoughts: Between SI and PSI, we have two complementary metrics that do a good job of informing whether above-the-fold loading process is fast and visually stable.
Normalized differences between these two metrics will be interesting to play with. This is because different screen resolutions will show different portions of the website without scrolling. Further complicating matters, many websites adjust their layout based on the size of the browser window, such that the fold is not a static feature of the page.

Nevertheless, many web advertising companies require ads be placed above the fold.
Marketing research done by Google shows that the viewability of adverts is affected by its position in relation to the fold as there is a significant drop-off below the fold. The BlogHer advertising network, for example, defines the fold as the top pixels of the page. Newspaper stories that appear below the fold are said to be located "under the fold.
Internet search query results appear much in the same way. Many web site optimization efforts may be exerted in an attempt to gain the highest "search indexing" or "ranking" placement as close to first place as possible for directed term s or phrase s.
Using natural or "organic" web site optimization practices has been the standard operating procedure for attaining higher indexing with the end result being the web site appearing in the view area or "above the fold" of the search results pages and especially the first page. The term is infrequently used in reference to resume and CV curriculum vitae layout, where the most crucial and relevant to the job sought information must be in the top third, alternately called the "hot zone", to catch the attention of the reader.
