SEO Tip #117: How is Google Helping Google Analytics Users with Site Speed?
Matt Cutts: Great question. So first off let me just remind people that Google announced this year that we do use site speed in our rankings but it’s not a huge factor. So maybe one out of 100 queries, which would correspond to 1 out of 1000 sites, might be affected. So it’s not the case that if your site loads just a few seconds slower than your other sites that you are instantly going to have to worry about your rankings.
And in general we don’t want to be on the critical path for anybody. Our mission is definitely to make the web faster. We offer everything from Google Chrome, which is very fast, to Google DNS, which also does look ups very fast so we want the web to be fast. Things like Asynchronous Google Analytics lets pages start to load and start to execute without having to wait on that Google Analytics.
