One of the biggest issues many companies face when using the AdWords API is that they store all the information at Google. It can be very time consuming (and expensive) to constantly download your information into a local database.

Over the past couple years, I’ve seen many companies who really needed to build a sync system to keep a local store of all information.

Google recently launched a code base and scripts to make this happen for their clients.

If you are an aggregator and need to take your API to the next level – check out sync:

AdWords API Changes:

We will add the following field to the KeywordEstimate object:

• clicksPerDay – (float) The estimated number of clicks generated per day for a keyword in a given ad group

Similarly, we will remove the following fields from the KeywordEstimate object:

• impressions – The estimated number of impressions for a given keyword
• ctr – The estimated click-through-rate for a given keyword.
• notShownPerDay – The estimated number of times that the ad would not be shown, despite a keyword match

The login changes at Google are sure to cause quite a bit of havic with those using MCCs, shared advertiser logins, and the API dev teams.

The Google API blog listed off some ‘best practices’:

Best Practices – Updating shared AdWords logins

Be sure to select “No. I might manage this AdWords account with others” during the first step of the update process

Create a new username and password that is different from the current AdWords username and password

Please advise your client to go through this same process (separate from you), and advise them to:

Choose a *different* username/password than you have

Avoid using their personal email address as their Google Account, but rather use their business or another professional email account as their login

Update your API headers as soon as possible to ensure that future API requests use your new Google Accounts login

Note: if you are accessing a client’s account via a My Client Center (MCC) account, be sure to also request that your client provide you with their new username so you can update your API headers accordingly.

Complete this update as soon as possible. While all AdWords users will not be required to update their account(s) for the next few months, we strongly suggest that you complete the process in early November, especially with the busy holiday season ahead of us.
