Google AdWords categorizes the level of relatedness between keywords and the search query under four different match types. The most accurate match type is “exact”. Accuracy widens over “phrase match” and “broad match modifier” to “broad match”.

deltamethod attempts to create keywords in the exact and phrase match type rather than in the broad match type. This attempt comes along with several advantages. First, due to the fact that keywords having exact/phrase match type trigger only highly related search queries, the overall costs decrease. Especially, for long tail keywords (keywords containing multiple words) using an exact match type is much more effective and cost efficient. Due to the fact that there is less competition, the CPC is lower. Moreover, these keywords are much more specific and therefore lead to higher CTRs and QS. Overall deltamethod recommends using a 60/40 imbalance of Long Tail Keywords and Short Tail Keywords. A good Long Tail Keyword captures customers, who have usually a higher willingness to purchase.
deltamethod recommends you to separate broad keywords from exact and phrase keywords in your account. This prevents an overlap in the budgeting process and thus cannibalization of traffic from happening.
For negatives we only consider three match types: “negative exact match”, “negative phrase match” and “negative broad match”. Analog to the above, they cut off traffic around the negative keyword.
