Pay-Per-Click (PPC) is a form of online advertising where advertisers pay each time a user clicks on one of their ads. This is in contrast to other forms of online advertising, such as display ads, where the advertiser pays based on the number of impressions (times the ad is displayed). PPC advertising is typically managed through platforms such as Google AdWords or Bing Ads, and can be used to drive traffic to a website, promote a product or service, or generate leads. In PPC advertising, advertisers create ads and bid on keywords relevant to their target audience. When a user searches for those keywords, the PPC ad may appear at the top or bottom of the search results page. The advertiser is charged each time a user clicks on the ad and is taken to the advertiser's website. PPC advertising can be a cost-effective way to reach a targeted audience, as the advertiser only pays when a user takes a specific action.

Here are the basic steps to set up a pay-per-click (PPC) advertising campaign:
1. Define your target audience: Determine who you want to reach with your ads and create a target audience profile based on demographics, interests, behaviours, and location.
2. Choose your platform: There are several platforms that offer PPC advertising, including Google AdWords, Bing Ads, and Facebook Ads. Choose the platform that best fits your target audience and advertising goals.
3. Select keywords: Choose keywords that are relevant to your target audience and that you want to bid on. These keywords will trigger your ads to appear when a user searches for those terms.
4. Create your ad: Write the copy and design the visual elements of your ad. Be sure to include a clear call-to-action (CTA) and make it easy for users to take the desired action, such as visiting your website or making a purchase.
5. Set your budget: Determine how much you want to spend on your PPC advertising campaign and set a budget accordingly. You can choose to set a daily or monthly budget.
6. Launch your campaign: Once you've completed these steps, launch your campaign and start bidding on keywords. Monitor your campaign's performance regularly and make adjustments as needed to ensure you're getting the best results.
7. Optimise your campaign: Continuously evaluate your PPC campaign's performance and make changes as needed to improve your results. This may involve adjusting your keywords, ad copy, target audience, or budget.

These are the basic steps to get started with PPC advertising. It can be a complex and constantly evolving field, so consider seeking professional help if you need more guidance.
