Google ads are one of the most powerful forms of advertising that you can use for every single business but are particularly useful if your business is small or a start-up.
Google Ads can bring in a high amount of business which could translate into sales due to the type of advertising that it is. The whole idea is that Google Ads shows your business at the top of the list when people search for keywords that relate to your product or service.
Google Ads also do not tie you into large sums of money or contracts, you can invest as little as you like so this can often be a cheaper form of advertising than say radios or magazines which are often expensive.
We think every business should at least trial using Google Ads to see if they will work for your business, and this is very dependent on your business sector. If your target audience is predominately offline then Google Ads may not be worth the investment but could potentially bring you new customers.
