The four main elements in a well-rounded SEO strategy are:

  • Keyword Research: Finding out what your target audience searches for
  • On-Page SEO: Optimizing webpages and their content
  • Off-Page SEO: Getting other sites to link to your site, which can boost its reputation
  • Technical SEO: Improving your site’s overall performance and accessibility

How Does SEO Work?

SEO aligns your website and content with the Google algorithm. Or, in other words, what Google looks for in good search results.

Basically, Google wants to rank webpages that:

  • Satisfy search intent (what the searcher is looking to achieve)
  • Demonstrate experience, expertise, authoritativeness, and trustworthiness (E-E-A-T)
  • Load quickly and perform well
  • Are easily navigable by users and search engines

So, SEO is about making sure your pages tick these boxes.

Some of the most common SEO tactics include:

  • Keyword research: Identifying and analyzing the search terms target audiences use
  • Content creation: Creating quality content that meets your target audiences’ needs
  • Link building: Getting other websites to link to your site so that it appears more trustworthy
  • Technical SEO: Improving the technical performance of your site for users and search engines

Why Is SEO Important?

SEO is important because it can improve your organic visibility in search engine results pages. Which can translate to more brand awareness and website traffic. Which ultimately leads to more sales. Businesses of all shapes and sizes have used SEO to their advantage. 

Here are 5 reasons why SEO matters:

1.Search Engines Generate Lots of Traffic

Ranking high in search engine results pages (SERPs) can get you lots of clicks. Which means lots of traffic to your website.

People use search engines to perform billions of searches every day.

And on average, over 43% of searchers click an organic result.

If you don’t capture the clicks available in your niche, your competitors will.

SEO is the tried-and-tested way to rank on more search results pages. And rank in higher positions.

This is important because prominent results tend to get more views and clicks:

2.SEO Can Be Highly Cost Effective

One of the main benefits of SEO is that it’s usually cost-effective.

Why?

First, there are no advertising costs. 

You don’t pay to appear on the results page. Or incur costs when people view or click your result. 

Second, SEO can deliver long-term results.

Once you’ve achieved high rankings, it’s possible to maintain them with relatively little effort (compared to channels like digital PR and social media). And relatively low costs (compared to paid traffic channels).

Building a strong foundation also makes it easier to gain or improve other rankings in the future.

In other words, SEO is highly scalable.

Just look at Morningside Acupuncture’s success story. Over three years, the company used SEO to grow their traffic by 2,900%.

3.Search Visibility Drives Brand Awareness and Authority

Frequently and prominently appearing in search results is an effective way to build brand awareness. And that’s one of the main reasons why SEO is important for business.

For example, searchers learning Spanish are likely to discover Duolingo quickly. Because the site ranks highly for thousands of topical keywords .  We can use Semrush’s Organic Rankings tool to see the  results.  

4.Your Competitors Are (Probably) Doing It.

If your competitors are using SEO, they’re probably outperforming you in search results. And getting exposure and traffic that could be yours.

If your competitors aren’t optimizing for search, you have a great opportunity to dominate the search results in your niche. And capitalize on all the SEO benefits available.

You can compare your rankings against competitors’ with Semrush’s Keyword Gap tool.

5.Optimization Efforts Can Improve the User Experience

Google wants to rank pages that leave its users happy. So you must create user-friendly content in order to succeed.

For example, these Core Web Vitals affect your performance in Google:

  • Largest Contentful Paint (LCP): How long it takes for the largest content element on the page to load
  • Cumulative Layout Shift (CLS): Measures how much the page layout moves around unexpectedly as it loads
  • Interaction to Next Paint (INP): The longest time it takes for the page to display visual confirmation of a successful interaction (e.g., for a menu to open).

Optimizing these metrics can help you rank higher. And improve the experience for users on your website.
