- if you once choose any match option for your keyword targeted ad capaign... you get stick to it... if you realise that its not being an effective choice then if you want to go for other match options you hav to sacrifice your keywords old performance history, ultimately your ad-position varries...you hav to start with zero again.
- you are not able to utilize all of the 3 match options for a particular keyword:
a) as if you go for another ad group, even though your keyword list remains the same
b) if you go for another campaign creation... it'll work against your old ad-campaign... & even adds up an extra cost to your ad budget
- if you want to choose an effective match option... its being harder to determine as because of dynamic nature of Search.
- You are unable to target every segment of your niche industry at once or through your adwords campaign at once.
There is another factor I forgot and in fact I posted about it a longtime ago and forgot about it. Expanded Match also uses all the keywords in your campaigns to generate ad results. I have a paused campaign for ML-1430 and it is linked to the same URL as my ML-1450 campaign. Expanded Match saw a ML-1430 query and popped up the ML-1450 ad. Pause for the ML-1430 keywords got overridden by Expanded Match.
