What Are the Types and Benefits of SEO Marketing?

SEO marketing involves optimizing a website and its content to improve visibility in organic search. It primarily covers on-page, off-page, technical, and local SEO. Its purpose goes beyond pursuing rankings: it also helps align content with search needs, increase brand exposure, and attract potential customers. Benefits may extend to website traffic and conversions, but exposure, visits, and sales are distinct outcomes. Higher rankings should not be treated as a guarantee of sales performance.

What does each of the four types of SEO improve?

Semrush divides SEO marketing into four categories based on what is being optimized and in what context. These are not four mutually exclusive marketing options:

• On-page SEO: Improving the content of web pages, such as incorporating relevant keywords and answering the questions readers are searching for.
• Off-page SEO: Improving search visibility through activities outside the website, commonly by acquiring backlinks from other websites.
• Technical SEO: Improving a website’s technical setup, particularly to help search engines access its content—for example, by submitting an XML sitemap or improving page speed.
• Local SEO: Increasing visibility for searches related to a geographic area or location. Optimizing a Google Business Profile is one approach.

Writing articles is therefore only one part of SEO. Whether content meets readers’ needs, whether search engines can access it, and whether local search visibility is needed are separate areas of work.

Keyword research: turning search needs into content direction

Keywords are not a separate set of SEO types; they are an important basis for content planning. Welly’s 2022 article groups search intent into three categories—navigational, transactional, and informational—to help explain what readers want to accomplish:

• Navigational: A search for “UNIQLO,” for example, aims to find a specific brand or content on its website.
• Transactional: Someone searching for “sneakers,” for example, may be researching products, comparing prices, or choosing a shopping platform.
• Informational: A search for “facial moisturizing,” for example, focuses on finding information or a solution to a problem.

This is the classification used by the source; it does not mean purchase intent can be determined from a single term alone. Its practical purpose is to clarify whether readers need brand information, product information, or answers to questions, then use that understanding to guide website categories and content direction, rather than simply pursuing high-volume search terms.

Benefits can extend from exposure to conversions, but each has limits

SEO’s most direct goal is to improve organic search rankings and visibility in search results, giving a website the opportunity to gain more direct or indirect traffic. Keyword research also helps align content planning and website development with customer needs.

Different needs also lead to different benefits. Welly notes that informational keywords have relatively low conversion rates but can help build brand awareness and nurture potential customers. Transactional keywords are generally more closely tied to shopping needs and face stronger competition. These are tendencies described by the source, not results every website can replicate. Traffic can create opportunities for conversions, but it does not directly equate to orders or revenue.
