Keyword Insertion is a great adcopy technique used in Search Engine Marketing (SEM) to increase ad relevance and Click Through Rate (CTR). It works by inserting the searched term into the headline.
Here is an example:
{KeyWord:Buy Puppies Today}
Buy Puppies at PetSmarty Today.
Best of Breed & Training Available.
The “Keyword” part of the headline will never show when the ad is served, only the default text “Buy Puppies Today” or the keyword string that triggered the ad. The default text will be used if the search query went over the 25 characters limit.
While “KeyWord” insertion ( capitalizing the first letter of each word) is the most common used for the english ads. However there are times when variations come in handy.
Here are different ways to use keyword insertion:
* keyword – [ buy puppies today ] – No capitalization, all word(s) are in lower case
* Keyword – [ Buy puppies today ] – First letter of the first word is capitalized
* KeyWord – [ Buy Puppies Today ] – First letter of every word is capitalized (** This is the standard DKI)
* KEYword – [ BUY puppies today] – Every letter in first word is capitalized
* KEYWord – [ BUY Puppies Today ] – First word capitalized AND first letter of rest of words
* KEYWORD -[ BUY PUPPIES TODAY] – Every letter for all words are capitalized
* KeyWORD – [ Buy Puppies TODAY ] – Capitalizes the first letter of every word AND all caps for the last word
Special Case DKI Use:
- State abbreviations
- Brand names
- Consistent look with body of adcopy
If for example you have state abbreviations in the headline, this is where you would want to consider carefully how to use Keyword Insertion. It is best to organize your keywords in separate adgroups that are consistent with the placement of abbreviations. For keywords such as “Lawyers in CA”, “Lawyers in FL”, would be in a separate adgroup with “KeyWORD” as the insertion to ensure the state abbreviations are capitalized properly. There is also brand abbreviations to consider. For example a brand such as HSBC would need to be in all caps to keep the integrity of the brand name. Also if for some reason you had all lower case ads text or upper casing, you could use the special DKI rules to create the same look for the headline as the rest of the ad.
As a best practice I have at least one ad in an adgroup use DKI. I usually have a mix of ads with static headlines and headlines using DKI within the same adgroup. Be wary of misspellings in your keywords, you do not want those appearing in your headline. This could have negative effects on your CTR results. I recommend placing all your misspellings in a separate adgroup with only static headlines.
