What Is Examples of SEO in Digital Marketing and How Does It Work

SEO is the practice of optimizing a website to rank higher in search engine results for keywords people are actually searching for. When someone types "best plumber in Denver" or "organic dog treats," search engines like Google use complex algorithms to decide which websites deserve the top positions. SEO is your systematic approach to winning those positions. The most common example is keyword optimization—researching which terms your client's audience searches, then building content and technical infrastructure around those terms. Another concrete example is link building, where you earn hyperlinks from authoritative websites to your client's site, signaling to Google that the site is trustworthy. A third example is technical SEO, where you optimize site speed, mobile responsiveness, and internal linking structure so search engines can crawl and index the website efficiently. These aren't separate strategies—they work together to improve rankings and visibility.

For agencies, SEO matters because it's one of the few digital marketing channels that generates compounding returns. A PPC campaign stops delivering traffic the moment you stop paying. An SEO investment, done well, keeps generating qualified traffic for months or years without additional spend. This makes SEO incredibly profitable to resell—clients get sustainable traffic growth, and your agency can charge recurring monthly fees to maintain and improve rankings. You're also solving a real business problem. Most of your clients lose potential customers to competitors who rank higher. When you move them from position eight to position three for high-intent keywords, you're directly impacting their revenue.

Practically, here's how to implement SEO for clients. Start by identifying the keywords they actually want to rank for—not vanity terms, but the searches that convert into customers. Use tools like SEMrush or Ahrefs to check search volume and competition. Then audit their current website to find technical issues: broken links, slow pages, poor mobile experience. Fix those first because you can't rank if your site is broken. Create new content targeting keywords in their service area or product category. For a local agency client, that might mean optimizing their Google Business Profile and building location-specific landing pages. For an e-commerce client, it's optimizing product pages with the right keywords and internal linking. Finally, start building authority by pitching your client's content to relevant websites in their industry and acquiring backlinks naturally. This is the long game—most keywords take three to six months to rank for.

The key for agencies is positioning SEO as the foundation of their digital marketing strategy, not an afterthought. When you're building someone's PPC campaigns or managing their social media, you should simultaneously be laying SEO groundwork. A client who ranks organically for their most valuable keywords isn't dependent on advertising budgets that can be cut. They're building actual business assets.
