Improving Page Speed: Does it matter?
• 2010: Speed added as a factor to Google algorithm– < 1% of searches effected, especially page 1 results– Fast does not mean you’ll get ranked in the top 10 (sorry)– Links and content are probably more important– Can influence long-tail results, bounce rates, conversions

Improving Page Speed: Does it matter?
• 2011: Google’s NYT released an article about Google’s energy usage:“[Google’s] data centers around the world continuously draw almost 260 million watts — about a quarter of the output of a nuclear power plant.”– Faster, more efficiently-built websites take less resources (see:
electricity) to crawl, index, deliver, etc.– Google has a thing for green stuff
• Saved energy = $$$• Saved energy also = “we’re good for the environment”
Improving Page Speed: Does it matter?
• 2012: Theme of Google’s Think Quarterly site: Speed– Urs Hoelzle (also quoted in the NYT article above)
The average web page takes 4.9 seconds to load – in a world where fractions of a second count, that’s an eternity.
I’m just sayin’…
• Web pages keep getting bigger Between 1995 and 2010, the average web page grew from 14k with 2.3 objects to 484k with 75 objects.
• Impact of 1-second delay A site that typically earns $100,000 a day could lose $2.5 million in sales this year.
• Shopzilla: Faster pages = 12% revenue increase In 2009, Shopzilla became the poster child for web performance when it shaved almost 5 seconds from its page load times and increased revenue by 7-12%.
• Amazon: 100ms faster = 1% revenue increase A mere five years ago, this was one of the earliest reported studies on the relationship between site speed and revenue.
• AOL: Faster pages led to 50% more page views In a 2009 study, AOL found that visitors in the top ten percentile of site speed viewed, on average, 7.5 pages per site visit. Visitors in the bottom ten percentile viewed just 5 pages per visit.
• Yahoo: 400ms faster = 9% more traffic In 2008, Yahoo! reported that making pages just 400 milliseconds slower resulted in a traffic drop of up to 9%.
• Mozilla: Faster pages = 60M more downloads By making just a few minor tweaks to top landing pages, Mozilla estimated that they drove an additional 60 million Firefox downloads per year.

Waterfall View
• Displays all files needed to completely render the page
• Pay close attention to the First View, this is the first impression and can make or break engagement!
• Most importantly, don’t go chasin’ waterfalls
Parallel Downloads
Pro tip: Conditional comments can block resources from loading in parallel in Internet Explorer. Place an empty conditional comment before any external resources to eliminate the blocking behavior.
