Has anyone had any problems with using the Phrase-match option for keywords in Google Adwords? According to Google's documentation, if you phrase match "tennis rackets" you will match against search queries as follows
x K y
where K is the keyword (in this case "tennis rackets"), x are any terms preceding the keyword and y are any keywords suceeding the keyword.
However, the results seem completely unreliable. Anyone else had this problem? If you think you don't have this problem and have Google Adwords, check the phrase matching thoroughly. It's a total crap shoot whether or not your ads appear. I'd welcome any info what's happening.
