Google Ads charges their advertising in a variety of ways depending on the type of campaign you’re planning on running. The most common type is paying-per-click (also known as PPC). This option is available across Google Search and you only get charged once a user clicks your ad. This option is great as you don’t get charged if a user sees your ad, think of it as free advertising.
Other placements across Google have the option to charge per 1000 impressions (cost / CPM) while others will charge you per. Conversion or sale. These other options depend on the type of placement you choose when you create your campaigns.
But you cam here asking for dollars didn’t you?
A solid minimum budget for local services should be $1,500 this will giive enough data to made real inroads and adjustments.
However if budget is limited I have managed to get a new business going on closing its first clients on as little as $300 as spend in a month.
