Google has adjusted Quality Score determinants for AdWords to reward pages that maintain high-quality landing pages.

On Monday, Google announced the expansion of a trial campaign that altered its algorithm for ad rankings by increasing the focus on quality landing pages.

Initially, Google rolled out the Quality Score shift only in Portugal, Brazil, Spain and other Spanish-speaking nations. Google believes it has perfected the change to the point where it can launch the initiative across the board.

The change will impact advertisers who don’t invest in top-notch content writing for landing pages, but it’s also a sign that overall content marketing efforts must meet Google’s standards if sites want search visibility.

“When searching on Google, users appreciate results that are relevant and deliver a great experience after they click,” Google said in its announcement of the new Quality Score tweaks.

Ultimately, Google’s various algorithmic changes have been aimed at crediting businesses that consistently monitor and improve their websites. Last week, Brafton reported that Panda 2.5 launched, which should indicate to marketers that algorithmic tweaks are constant and tailoring sites to the engines, alone, is not a method for long-term SEO success. Instead, they must continuously strive to offer high-quality, relevant content.
