My recent post about page growth (or page shrinkage, as the case may be) hit a nerve with a lot of people, so this week I thought I’d take my first dive into the Mobile HTTP Archive, the mobile counterpoint to the HTTP Archive I cited last week. The Mobile HTTP Archive tests the same list of URLs, but it does so using smartphones. This means that if a URL redirects to a mobile site, the Archive tests the mobile site.

Just like last week, I looked at the top 1,000 URLs. What I found won’t come as a surprise to anyone who’s been following this blog for a while. While there are many similarities between these findings and last week’s, there are also a number of insights that are unique to mobile devices.

Earlier this week, I had the privilege of speaking at the RWD Summit, alongside awesome folks like Tim Kadlec, Brad Frost, and Jenn Lukas. I presented some of the findings of research we conducted here at Radware about how mobile users engage with ecommerce sites, and how this engagement is affected when pages are slowed down even by marginal amounts.

Yesterday on Twitter, I posted a link to this Internet Retailer article about the results of a recent Keynote mobile index report. The report found that only two out of the 30 sites in the index use responsive design, and both those sites took 17+ seconds to load on mobile devices.

My Twitter post (sorry, I just can’t say “tweet”) generated some discussion about the challenges of making fast responsive pages, with some folks taking the stance that RWD and performance don’t play well together. This isn’t a new opinion, and it’s sparked a lot of debate in the past. (See this post from Tim Kadlec and this one from Guy Podjarny for excellent examples.)

Google Instant is going to fundamentally change how people search. Eventually, page 2 search results are going to be irrelevant. Page 1 will be the new bar. The companies that hit that bar will be the companies that are ready to squeeze every last ounce of performance from their sites.
