Last month Google added Website speed to its site ranking algorithm: It’s Official: Google Now Counts Site Speed As A Ranking Factor… The rationale behind this move by Google is fairly straightforward:
Slow web sites lead to a poor user experience, and therefore should not appear at the top of the search list even if they contain relevant content.
This emphasizes once more the influence of performance on your daily business. A simple change to your site can now affect your entire page ranking and how users find your content. Continuous performance testing is now even more important than ever.
