A few general tips for new advertisers

[AdMob Support]

Hi,

We understand that many of you are using specific age and gender
targeting for your ads. Since only a portion of our publisher sites
provide us with this information, this can reduce the rate at which
your ads are displayed. We'd encourage you to consider either
increasing your bid, which would make your ad more competitive for
display on sites/apps that capture demographic information, or
removing the demographic targeting from your campaign. This type of
inventory can be much more expensive and more limited in supply than
more general inventory.

AdMob moderates all ads that run on our network. Approval time can
vary, but we make every effort to approve ads within a few business
days after submission.

Likewise, there can be a short delay between when you add funds to
your account by credit card, and when we approve the credit card
order. This delay allows us to evaluate your order and prevent credit
card fraud.

An ad will only begin to run:
(1) once your credit card order is approved -- you'll receive a
notification email
(2) once your ad is approved -- you'll also receive a notification
email

Please understand that there's very little we can do to speed up the
ad approval process or to explain why you're not getting more
traffic. The best way to accelerate the traffic your ad gets is to
increase your bid or to broaden your targeting settings.

One final thing to be aware of is that statistics take about 90
minutes to populate in our system. So before generating a report of
your campaign's performance, be aware that the statistics you see may
not reflect the last 90 minutes of activity.
