When you place quotation marks
around the phrase match
keyword, all the words must be entered into the search engine query box in order for the PPC advertisement to be triggered, but the advertisement can also be triggered when the phrase is entered and another word is included either before or after the
quoted phrase too.
Non branded search is
keywords people use when they don't have a particular company / brand in mind, they are just searching
around a particular topic, for example «car insurance», «car insurance
quotes», «car insurance
quotes online» would be non branded search where as «money super market», «go compare car insurance» etc would be examples of branded search.
