I have done some research and have found GO TOAST and several other services/tools that seem very expensive.
Can anyone recommend reliable, reasonably-priced SEM campaign management tools that are either software-based or web-based? I primarily focus on Google and Overture campaigns, but I need to manage multiple campaigns for multiple clients.
On a smaller scale, it seems that the fees for the automated tools may make it a wash when you compare a campaign that is a little less efficient & therefore more expensive, vs spending up to $0.05 per click + setup & management fees.
Not sure of anything that really "manages" AdWords campaigns well but one of those tools completely wrecked one clients' [AdWords] campaign a while ago and the tool was nearly impossible to use.
In short, you've still gotta go into the Google interface in order to get some things done.
The key to managing multiple client campaigns across multiple search engines it PROCESS... You've got to focus on automating as much as possible the areas you can, such as reporting, keyword generation etc...
Because until Google follows Overture's lead and allows 3rd parties to fully access its management, that will be one area you'll have to devote time to...
