5 Tips to Building an Effective Google Adwords Campaign
* Budget delivery — choose a staggered delivery throughout the day for even distribution over each 24-hour period or accelerated delivery. Accelerated delivery serves ads until the budget is reached, regardless of how quickly that may occur. Be careful with this option, however, as it may deplete your budget from people searching late at night/early morning. Consider this option if you’re running a timed promotion or offline marketing effort to achieve maximum exposure when you need it most.
If you can’t find your ads, your budget may not be big enough to support what you’ve included in your Adwords campaigns. Google recommends daily budget amounts based on what exists in the campaign and its pricing/search volume. It also tells you exactly how much of the market share (for your search terms) you’re missing, given the current budget parameters.
