What is SEM?
Search Engine Marketing (SEM) is a digital marketing strategy focused on increasing a website’s visibility on search engine results pages (SERPs) through paid advertising. SEM involves the use of platforms like Google Ads or Bing Ads to drive targeted traffic by bidding on relevant keywords.
Key Components of SEM
1. Pay-Per-Click Advertising (PPC)
Advertisers pay each time a user clicks on their ad.
- How it Works: You bid on keywords related to your business. When users search for these keywords, your ad may appear at the top of the search results.
- Key Metrics: Cost-per-click (CPC), Click-through rate (CTR), and Ad Rank.
2. Ad Campaigns
Creating targeted campaigns tailored to specific goals like sales, leads, or website visits.
- Key Practices:
- Search Ads: Text ads displayed on SERPs.
- Display Ads: Visual ads shown across Google’s Display Network.
- Shopping Ads: Ads featuring product images, prices, and links.
- Video Ads: Ads run on YouTube and other video platforms.
3. Keyword Research
Identifying and targeting keywords that users are searching for.
- Key Practices:
- Use tools like Google Keyword Planner, SEMrush, or Ahrefs.
- Target a mix of high-volume and long-tail keywords.
- Analyze competition and CPC for effective budgeting.
4. Ad Auction & Quality Score
Search engines determine ad placements through an auction system based on:
- Bid Amount: How much you’re willing to pay per click.
- Quality Score: A measure of your ad’s relevance and quality (CTR, landing page relevance, and ad copy).
5. Landing Page Optimization
Ensuring that the page users land on after clicking an ad is highly relevant and optimized for conversions.
- Key Practices:
- Fast loading speed.
- Clear call-to-action (CTA).
- Mobile responsiveness.
