Google has kept a promise it made last year: Site speed is now a ranking factor in Google’s algorithm, and is already in place for U.S. searchers. But Google also cautions web site owners not to sacrifice relevance in the name of faster web pages, and even says this new ranking factor will impact very few queries.
Why Page Speed Matters
The first warning that site speed was on Google’s radar came last November, when Cutts said there was “strong lobbying” inside Google to account for site speed as a new ranking factor. Speaking at SMX West last month, Google’s Maile Ohye showed a slide indicating that delays of under a half-second impact business metrics.
Site speed is analyzed based on a set of rules for high performance. Speed now effects your overall search engine optimization.
