Google to change Quality Score algorithm
Google is planning to make changes to its AdWords online advertising system next week, changing the Quality Score algorithm, Marketing Pilgrim reports.In a move designed to "improve transparency" and make it easier for advertisers to understand the quality score, the search engine will alter the Quality Score algorithm and show the Quality Score in a new column in AdWords campaigns.
Google's Quality Score is the basis for measuring the relevance and quality of ads and therefore determining advertisers' CPC bids. It is determined by various factors such as the click-through rate, and the relevance of the ad text.
The company is expecting something of a backlash when the algorithm is changed, as it "will impact a fairly large number of keywords". However, it maintained that the change was aimed at improving quality and would "help advertisers optimise their ads".
Google's Nick Fox told ClickZ News: "This is a change to the algorithm itself, updating what we call 'prediction confidence' to improve the accuracy in determining quality score in cases where we have less data."
AdWords has become indispensable to internet marketers who have realised how simple and effective search ads are.
Meanwhile, research from Outsell has shown that Google is officially the biggest company in the information industry.
