SEM vs. SEO: What’s the Difference?

Pay-Per-Click (PPC) Advertising 

Understanding PPC is essential to mastering SEM. 

How PPC Works 

PPC allows businesses to bid on specific keywords relevant to their audience. When users type those keywords into search engines, ads appear at the top of the SERP. Advertisers only pay when someone clicks on their ad, hence the name, “pay-per-click.” 

Key components of PPC campaigns include:

• Bidding: Setting the maximum amount you’re willing to pay per click. 
• Ad Placement: Determined by a combination of bid amount and ad quality (known as the Quality Score). 
• Quality Score: Evaluates your ad’s relevance, click-through rate (CTR), and the quality of your landing page. 

Keyword Research and Selection 

Effective PPC hinges on selecting the right keywords. Consider using tools like Google Keyword Planner or SEMrush to uncover high-volume, low-competition keywords that align with your audience’s search intent.

Great ads are clear, compelling, and action-oriented. Focus on showcasing benefits, urgency, and irresistible calls to action (e.g., “Save 50% Today!”). Use the small character limit wisely by highlighting what makes your product or service unique.
