You can view the new statistics by looking at the Keyword Tool's Approx Search Volume columns. Search volume data can be useful to you in several ways, including:
- Account structure: You may want to create a new ad group around high-traffic keywords that you find particularly relevant. Closely target ad text and a specific landing page to the small, narrowly-focused set of similar keywords you've found through the Keyword Tool.
- Budget planning: See how much traffic is available to your keywords so you can better plan your budget.
- Keyword choice: Search for and select the relevant keywords most likely to return quality leads within your budget.
Remember, the Keyword Tool also provides several other keyword-related metrics that can help you select highly relevant keywords to improve the overall performance of your campaigns. You can easily view data on advertiser competition, search volume trends, estimated average CPCs, and estimated ad positions for keywords.
