Fast and efficient account set-up and an easy to use interface are two reasons goClick has a large base of satisfied customers. Taking a straightforward approach, the goClick account management system displays your account balance, how much you have spent, and number of clicks received. You can easily toggle between sub-accounts and review lists of keywords and bid prices. A simple click of a button and you can change your traffic zone settings, or pause accounts and sub-accounts.

Adding keywords is quick and easy; there is even a bulk submission tool which allows you to add thousands of words at once, simplifying the process even more. Change bid prices, delete or modify keywords, and edit site details easily.

Using BidMaster, a keyword bid price tool, you can adjust bids for an entire sub-account quickly and easily. You can adjust your bid prices so that you are in the highest position possible while setting a maximum bid price. Bids can always be adjusted using the "Change Bids" page, but it is more time consuming.

Once you enter the amount you are willing to pay and click 'submit', BidMaster will automatically adjust all of the keywords to the maximum position possible up to the maximum bid. There are three options with BidMaster:

Standard BidMaster: Runs manually, meaning advertisers must log in and specifically run it to adjust the bids.

Auto BidMaster: A special option that sets BidMaster to run automatically once per night. This removes the worry about overpaying for a position or missing potential traffic for days at a time.

Power BidMaster: Power BidMaster adjusts bid prices using the bid values of goClick's partner network, rather than the bids within the goClick site itself.
Reporting on your goClick campaigns allows you to view clicks and transactions at a glance.(from http://www.payperclicksearchengines.com/directory/top-10-ppc-search-engines/google-adwords-l252.html) .
