February 4, 2021changes to phrase match and broad match modifierAdWords APIGoogle Ads APIGoogle Ads scriptsHow does this change affect the AdWords API, Google Ads API and Google Ads scripts?What impact should advertisers expect?

Advertisers predominantly using phrase match are expected to see an incremental increase in clicks and conversions

This is due to the additional queries to which these keywords will now be eligible to match. For example, “holidays in zambia” as a phrase keyword will now begin to match to “holiday spots in zambia”, which was previously only eligible for BMM.

Advertisers predominantly using BMM are expected to see a slight decrease in clicks and conversions

The majority of this loss is from BMMs where the modifier was only applied to part of the keyword, e.g. tennis +shoes.
In addition we are now considering word order when it’s important to the meaning of the keyword, so some matches that previously matched to BMM will be filtered out.

Changes to quality score in AdWords scripts

Monday, August 15, 2016

We are making some changes to the way AdWords scripts returns quality score data for keywords.

We will return a null quality score for keywords that don’t have enough impressions and clicks to determine a Quality Score, such as new keywords or old ones that haven't served a long time. This will impact your scripts in two ways:

Reports: Starting with version v201607, the Critieria Performance and Keywords Performance reports will return a quality score of “--” for these keywords. Past versions (v201605 and earlier) of these reports will remain unchanged.
getQualityScore method: Starting the week of Sep 12, 2016, the getQualityScore method of the Keyword entity will return NULL score for these keywords instead of a numeric value.

If you use use quality score information in your script, please make sure you update it to work with the new changes.

Filtering on quality score

Filtering on quality score will work as follows:

If no filtering conditions are specified on the QualityScore field, all matching keywords are returned, including those with NULL quality score.
If numerical filtering conditions are specified on the QualityScore field, keywords with NULL quality score information are excluded automatically. For example, QualityScore <= 6 will include keywords with quality score from 1 to 6 but exclude keywords with NULL quality score.
To retrieve keywords with NULL quality score, filter using the condition HasQualityScore = FALSE.
To retrieve keywords with NULL quality score along with keywords with specific quality scores, you need to run two separate reports and combine the results locally.

If you have any questions about these changes or AdWords scripts in general, you can post them on our developer forum.

Introducing the Keyword Optimizer sample app for the AdWords API

Friday, March 4, 2016

In AdWords, finding the right keywords to trigger your ads is one of the main drivers of success — yet a major challenge at the same time. You can use our Keyword Planner to browse for new keyword ideas, or utilize the AdWords API services for keyword suggestion and traffic estimation to find and evaluate keywords at scale.

But wait, now there’s more! We’ve just released KeywordOptimizer, a sample app showcasing how to combine these services to find the perfect set of keywords. Starting from an initial set of seed keywords (obtained using a sample URL, business category etc.), the iterative process repeatedly discards low-quality keywords and “reproduces” high-quality ones. With each step, the average quality across all keywords increases, just like evolution!

KeywordOptimizer is designed to provide guidance on how to use the TargetingIdeaService and TrafficEstimatorService. Simply run it from the command-line to get a CSV file with keywords and estimation with minimal effort. Advanced users can easily extend the tool with custom implementations. For example, you can change the calculation for the keyword quality score to combine clicks with impressions, or your own metrics in a way that works best for you.

Get started with Keyword Optimizer’s GitHub repository. Feel free to ask questions or give feedback via the project’s issue tracker, the AdWords API Forum, or our Google+ page.
