AdWords express takes away most of the control of your campaign, you cannot edit your keywords so you will appear in more searches but those searches will not be relevant to you,
Eg:......i tried it and it created the key phrase 'hull cleaners' which if it was hull carpet cleaners it would have been useful,..... but with just 'hull cleaner' I was getting clicks for people who justt wanted a cleaner not a carpet cleaning
also the key words were listed as some sort of algorithm so you couldn't not see what the key word actually was......
( i have just looked at my campaign page and here is a keyword used in my AdWords express campaign.....
CampaignMgmtstylePrefOverride=2&__u=5156432189&__c=7116632909#a.3072348431_66204191 what does this mean?
??
with a normal AdWords campaign i was spending £30ish a month with a CPC of 90p but with express the cost was set at £3
to me express is for people who don't know how to use normal adwords
