Search Ads

Campaign were duplicated and targeted according to devices (mobile and desktop) that users utilized while interacting with the ads. The advertising budget can then be allocated more efficiently according to the results of the campaigns based on the interactions. This will also help to reduce the cost per acquisition.


On top of that, responsive search ads and dynamic keyword insertion were utilized to improve click-through-rates by matching the ad to the intentions of the users as closely as possible via Google machine learning.


Responsive search ads were implemented to showcase ads that are most relevant to potential customer’s searches. Multiple headlines and descriptions related to the campaign are entered. Google’s machine learning algorithm will then test, learn and optimize for the best performing combination of expanded text ads according to search query.


Dynamic keyword insertion contains the dynamic keyword insertion formula that matches the user’s search query in the creation of a generic ad. When the ad is served, the dynamic keyword insertion formula will substitute the keyword that triggered the formula in the ad. This creates a more specific and highly targeted ad that perfectly matches the searcher’s intent.

Responsive Display Ads

Responsive display ads were launched. Google assembles and adjust the size, appearance and format of the responsive display ads to fit just about any available ad space to maximise the ad via Google machine learning.


Audience profiles created were targeted at specific pest types. For example, bed bug ads were targeted at frequent travellers via affinity and in-market audiences.
