Allows you to enter a specific date range so you can see the average monthly searches for that time period.
You can also compare two different date ranges. This could be useful to determine whether certain keywords perform better during different periods of the year, helping you design strategies for your campaign calendar.
Average Monthly Searches: Filter keywords special lead based on the average monthly searches for the selected dates. Keywords with extremely high search volume (usually more than 10,000 average monthly searches) are harder to compete with, with a higher suggested bid.
If you're just starting your campaign, focusing on keywords with mid-level search volume can help you avoid overspending your budget.
Suggested bid : This allows you to view keyword options that could help you better control your budget. The suggested bid is calculated based on the cost-per-click (CPC) that other advertisers are paying for keywords with the same location and Search Network settings you've selected.
Ad Impressions : The number of times people see your ad, divided by the total number of searches matching your keyword in the last month for the target location and network.
