Which is a benefit of advertising online with Google AdWords?
Advertisers can choose how much they spend and only pay when someone clicks their ad
Advertisers can choose how many times their ad should show during the day
Advertisers pay the same amount every time someone clicks their ad
Advertisers can pay to always show their ad above the organic search results
One of the most important benefits of internet marketing is that you can completely control how much you want to spend and can adjust your bids in very flexible way. In AdWords, you can assign a daily budget to each individual campaign, or use shared budgets to allocate budget across multiple campaigns. A shared budget is ideal if you don’t have a lot of time to spend setting up and monitoring individual campaign budgets, but would still like to get the most clicks possible for your ads within a set budget.
You decide how much you want to spend, and pay only when someone interacts with your ad, like clicking your text ad or watching your video ad. You base your bids on whatever is best for your business.
