Google has announced that its Page Speed Online tool (which gives marketers and developers recommendations for improving their sites' speed to improve SEO) has “a shiny new API.”

The company is introducing the Page Speed Application Programming Interface to help site owners integrate speed performance analysis into their dashboards. The company is offering a getting started guide for developers to help them understand how to make it easier for their pages to interact with Page Speed Online.

Businesses that incorporate this tool may benefit from better SEO. “You can use the Page Speed Online API to programmatically generate Page Speed scores and suggestions,” explains Google.

With the Page Speed API, marketers can get page speed analysis for both mobile and desktop performance. This means businesses can gain automatic insight on how to optimize sites for both traditional and mobile searchers.

As Brafton has reported, site speed is a ranking signal for SEO. In fact, Google's Matt Cutts emphasized that site speed should be one of marketers' top SEO priorities for 2011.
