If you’ve ever wondered how certain websites rank at the top of Google search results, the answer is simple: SEO.

Search Engine Optimization (SEO) is one of the most powerful tools in the digital marketing playbook — and understanding it can help you grow your audience, increase sales, and strengthen your brand.

Whether you're running a small business, launching a newsletter, or selling online, this guide will help you understand what SEO is and how it fits into your larger digital marketing strategy.

What Is SEO in Digital Marketing?

SEO (Search Engine Optimization) refers to the process of improving your website's visibility in search engine results — primarily on Google. The goal? To drive organic (non-paid) traffic to your site by ranking higher when users search for relevant keywords.

A well-executed SEO strategy can help your content reach the right audience at the right time — and without relying solely on paid ads.

‍

Why Is SEO Important?

In 2025, attention is currency. And with billions of searches made on Google every day, being discoverable is crucial.

Here’s what strong SEO can do for your business:

• Drive organic traffic to your website or landing pages
  
• Increase brand visibility and trust
  
• Attract qualified leads that convert
  
• Work hand-in-hand with your email marketing and content strategy
  

For example, combining SEO with your newsletter efforts is a winning strategy. If you haven’t already started building your email list, here’s how to create a newsletter people actually read.

Core Elements of SEO

1. Keyword Research
   This is the foundation of SEO. Identify the words and phrases your ideal audience is searching for — then naturally incorporate them into your content, titles, and meta descriptions.
   
2. On-Page SEO
   This includes optimizing your content structure, headings, images (with alt tags), internal links, and URLs. Parlo’s blog, for example, uses strong internal linking to help readers discover related tips like these 10 things to avoid when writing emails.
   
3. Technical SEO
   Ensure your website is mobile-friendly, fast-loading, and crawlable by search engines. Clean code and proper site architecture matter more than ever.
   
4. Content Creation
   Google loves high-quality, useful content. Think blog posts, tutorials, product pages — all optimized with keywords and formatted for readability.
   
5. Off-Page SEO
   Backlinks from trusted sites improve your authority. Think of it as “word of mouth” for your website. Guest blogging and sharing on social media can help.
