Our normal approach would be to have our account filled to its limit with exact match and long tail phrase match keywords, plus common misspellings, etc. We provide a very specific service, and have only 20-30 core words that appear in our phrases, but the varying word order and additional words such as "to," "for," "my," "your," etc. make it very easy to build those 20-30 out to 20 or 30,000 in the snap of a finger. At Google (for now), we intend to drop the less common phrases, and reduce thousands of 7 word specific phrases to 3-5 word less specific phrases.
My Questions:
1) With phrase match, will Google consider our ad/keyphrase for appearance under search queries that contain misspellings either before or after our phrase matched key phrase?
Example Key phrase: "hate google adwords"
I realize that the above keyphrase could qualify our ads to show for "YOU hate google adwords," and "WE hate google adwords," but will it be considered for "YUO hate google adwords," or "WEE hate google adwords," or are misspellings limited to broad match and/or the actual use of misspellings in key phrases?
2) With a refined set of keywords, how long does it generally take in the Adwords system before enough of a history / quality score is developed enough for us to begin to introduce the usually more profitible elements of our campaigns, such as our lesser searched long tails and misspellings?
Hope I've made sense. Thanks in advance for any assistance.
