In conclusion, you need to examine the queries attracted by keywords with broad match types such as partial match, select the ones with the highest affinity, and then set those queries as new keywords.
By going through this process, the keywords you set will philippines whatsapp group be increasingly composed of "target keywords," and by strengthening your bids for those keywords, you will be able to secure ad displays and increase your exact match impression share (middle of the diagram above) .
Then, by repeating the above steps of adding queries, you can eventually change keywords with broad match types such as partial match that have attracted a wide range of queries to narrower match types such as exact match, and grow into an " ad group with high targeting purity " that can reliably attract the queries you are aiming for (lower part of the image above) .
(Of course, in the world of search, new queries are constantly being created every day, so ultimately it would be difficult, though ideal, to limit it to "exact matches only." However, in order to realize the AdWords platform's philosophy of "capturing user needs and returning highly relevant ads," it is expected that we can get as close to that as possible.)
And if the ad group grows into one with high targeting purity, it will have a positive impact on both actual and estimated CTRs, and it will create an environment where the relevance of ads and keywords is more easily improved. As a result, you can expect an improvement in the quality score of the keywords in the ad group.
In other words, an increase in exact match share indicates an increase in the degree of match between the set keywords and the query along the keyword axis that makes up the ad group. This increase in match contributes to an improvement in quality score, which can result in improved ROI.
And what makes this process easier is the keyword flags mentioned earlier.
