Have you ever noticed that every new keyword you add to an AdWords account has a default quality score of 6? Only after being live for at least a day and receiving some impressions will it change. This is because in July 2015, Google implemented an update to the way they report quality scores for keywords.
Before this announcement, Google would assign a quality score based on the overall account level quality score. This was a hint to marketers on their AdWords account health.
The update didn’t alter Google’s process of calculating account level quality score; it just made it more difficult for marketers to get an approximation of it.
How to Calculate Account Level Quality Score
Disclaimer: This method works best for search network accounts with keyword based campaigns. Display, video, dynamic and PLA campaigns are assigned quality scores by Google but they are not visible.
Ok, firstly you will need to download the data which is made simple with the AdWords interface.
- Set the date range as ‘Last 30 Days’, this will ensure the account quality score is up to date
- At the All Campaign level, click to the Keywords tab.
- Ensure you are showing all but removed keywords.
- Click on the Columns drop down and Modify Columns…
- Ensure Quality Score and Impressions are added to the set of columns
- Click the Download Report button (the arrow)
- Download report as Excel.csv and open
Now you have data from the last 30 days for every keyword in your account. Account level quality score is a weighted average based on the number impressions for each keyword. This means the more times a keyword has been shown the more it will affect the account level quality score.
It is simple do the calculation for a huge number of keywords with Excel.
- Delete every column except Impressions and Quality Score
- Create a new column Impressions x Quality Score
- The sum of Impressions x Quality Score column divided by the sum of all the Impressions gives the account quality score
|Keywords||Impressions||Quality Score||Imp x QS|
So, after a quick 10-15 minutes you can easily evaluate the overall quality of your AdWords account!
Why is Quality Score Important?
Google calculates a keyword’s quality score by its CTR, relevance of keyword to ad group, landing page experience and relevance, ad copy relevance and the historical account level quality score.
Quality score is of vital importance for two AdWords metrics:
Any keyword’s Ad Position is determined by Ad Rank. Ad Rank is calculated by the keyword’s Max CPC bid multiplied by its Quality Score.
As shown above, the keyword with the higher quality score will receive a higher Ad Position and greater ad exposure.
Another factor influenced by Quality Score is cost per click. Ensuring your keywords are running at a high quality score will help to potentially save money compared to your competitors.
As quality score increases, the amount you pay per click reduces.
How to Improve Account Level Quality Score
Get Rid of Low Quality Score Keywords
If you have keywords with a quality score of 5 or below that receive low impressions and conversion rates then make sure you remove them from the account.
Use Brand Keywords
Someone searching for your brand is very likely to click on an ad for your brand – it’s common sense but this will result in a high CTR and therefore high quality score. This will give your whole account a boost!
AdWords takes regular tweaking to ensure your account is running at an optimal level. Even 30 minutes a week dedicated to smart PPC optimisation will have a great effect.
