Google is always working on improvements that will help show the most relevant ads to searchers. Today they announced two changes designed to enhance how they calculate a site’s Quality Score and display rank.

Google announced today they will be changing certain components to its algorithm over the next several days. The first change will help better evaluate the precise quality of an ad – regardless of its position on the page. The second change will improve how Google promotes ads to positions at the top of search engine results pages (SERPs). Let’s take a look at both of these changes in more detail.
More precise Quality Score calculation
Google is now weighing Click-Though Rate (CTR) as the most significant component of Quality Score because it directly indicates which ads are most relevant to searchers. Typically, ads in high positions earn better CTR than those in low positions, because ads in higher positions are more visible to searchers. To calculate the most accurate Quality Scores, it’s important that the influence of ad position on CTR be taken into account and removed from the Quality Score. In the coming days, Google will update the portion of the Quality Score algorithm that accounts for ad position. This will result in more accurate Quality Scores, ensuring that ads compete fairly for position based on their quality and bid, and enable Google to show the most relevant ads to searchers by rewarding high-quality advertisers with better ad positions.
Higher quality ads above the search results
Google is also changing the way they determine which ads show in the yellow region above the search results. These positions are particularly valuable to advertisers because they are prominently positioned on a SERP page. Given their prominence, it’s especially important that these ads be high quality; therefore Google will place extra emphasis on quality when determining which ads to show in this location. To appear above the search results, ads must meet a certain quality threshold. In the past, if the ad with the highest Ad Rank did not meet the quality threshold, Google may not have shown any ads above the search results. With the coming update, Google will allow an ad that meets the quality threshold to appear above the search results even if it has to jump over other ads to do so. For instance, suppose the ad in position 1 on the right side of the page doesn’t have a high enough Quality Score to appear above the search results, but the ad in position 2 does. It’s now possible for the number 2 ad to jump over the number 1 ad and appear above the search results. This change ensures that quality plays an even more important role in determining the ads that show in those prominent positions.
Keep in mind that these enhancements may cause changes to any campaign’s ad position, spend, and performance. The good news is that this will level the playing field even more across competitive industry segments – especially for non-branded keyword terms. Google is essentially announcing that they are weighing in favor of "more clicks with lower bids". Our assumption is that challenging economic times have forced businesses and organization to bid down of keyword terms and thus search volume is likely down. As a result, Google is changing their algorithm in an attemp to maximize clicks – even if they come at a lower cost-per-click.
