Short answer: Yes, but it depends.

There are various factors that determine if PPC Advertising will be effective for your business.

PPC Advertising is most often based on an ‘auction’ where various businesses, marketers, and brands bid on a cost per click. The platforms then take those bids along with other factors to determine what ads to show and in what positions. The lower your ad or the less often it appears, then the less likely your ad is to be effective.

Because PPC advertising is based on keywords typed (or spoken) into a search engine by a user, then a PPC advertiser also needs to bid on the keywords that would most likely lead users interested in making a purchase or otherwise converting.

PPC is advertising, so hopefully it should be obvious that your ads themselves will also determine if your PPC Advertising campaigns will be effective.
Finally most PPC ads lead users to a landing page on a website. The content of this page, how quickly it loads, the aesthetics of the page, and how well the page matches the ads users clicked will all be a final determination of how effective your PPC campaigns are.
