SEO (Search Engine Optimization) is a comprehensive set of activities aimed at eliminating technical website errors, improving site readability for search engine bots, and enhancing user experience. The primary goal of SEO is to help users quickly find the information they need—information that most accurately matches their query in search engines like Google, Bing, Yahoo, and others. The task of SEO specialists is to optimize the website so that it earns the trust of search engine bots, which in turn helps the target audience discover your product, service, or content and perform desired actions: purchases, orders, subscriptions, etc.
However, search engine promotion is a lengthy and costly process that doesn't guarantee immediate results. This is why many projects postpone SEO efforts, causing their websites to remain unnoticed in search engine results.
How Do Users Search for Information?
When people search for something online, they enter keywords or phrases into the search bar—terms they believe will help them find the necessary information. For example, to learn what SEO is, users might search for queries like "what is SEO?", "SEO optimization meaning", or "search engine optimization". In response, the search engine returns a list of websites sorted by specific criteria.
Typically, users rarely go beyond the second page of search results. Therefore, to attract more traffic, a website must reach the TOP—appear among the first positions in the search results. The higher a site ranks in search results, the greater the likelihood that users will click on it.
Search Engine Results Page (SERP) Features
Besides the standard list of websites, search results may include various informational blocks. For example, searching for "what is SEO" might display a definition block, infographics, related queries, and other elements. These are often called the "zero position" because they don't have a numbered place in the organic results.
Main types of SERP features:
- Related queries — a block with questions and short answers.
- Rich snippets — enhanced results with additional information such as lists or tables.
- Featured snippets — concise answers to specific questions.
- Image carousels — blocks with images, products, or brands.
- Contextual ads — paid advertisements matching the user's query.
- Knowledge Graph — a block with detailed information about a person, object, or event.
Search engines aim to fully satisfy user intent, so they rank websites by relevance and usefulness. But how exactly do search engines work?
How Do Search Engines Work?
For a website to appear in search results, it must go through three stages: crawling, indexing, and ranking. This is handled by search engine bots (crawlers) that analyze a site's content, its freshness, and the credibility of the information.
- Crawling — bots navigate the website, discover new pages, and follow links.
- Indexing — the bot determines the page's topic and adds it to its database if the content is deemed useful.
- Ranking — the bot selects the most relevant pages from the index and displays them in response to a user's query.
The SEO specialist's task is to improve the website so that the search engine considers it valuable and displays it in the TOP results.
To achieve this, various optimization methods are used.
Optimization Methods
In the past, search engines were less advanced, and websites could be easily promoted using unethical tactics, such as keyword stuffing or mass directory submissions. Today, search engines are smarter, and such methods no longer work. SEO optimization is now divided into white, gray, and black hat techniques.
White-Hat SEO Methods
White-hat methods are approved promotion techniques that comply with search engine guidelines. They include on-page and off-page optimization.
On-page optimization begins with niche and competitor analysis and creating a semantic core—a set of keywords that the site will target. It's also essential to work on the technical aspects: checking page load speed, fixing broken links, optimizing meta tags, and improving site structure.
Off-page optimization involves building brand mentions and backlinks from other websites, as well as improving the site's reputation. It's important that links to your site appear naturally, for example, due to high-quality content.
Gray-Hat and Black-Hat SEO Methods
Gray-hat methods are promotion techniques that are not explicitly forbidden but are not endorsed by search engines. For example, buying links through link exchanges. Black-hat methods are prohibited techniques, such as cloaking (showing different content to users and search bots) or keyword spamming. Using such methods can lead to penalties from search engines.
Advantages and Disadvantages of SEO
SEO is a necessary tool for website promotion, but it's important to understand its characteristics.
Advantages:
- Cost-effectiveness — SEO attracts targeted traffic ready to make purchases.
- Long-term results — SEO outcomes are sustainable over time.
- User trust — top-ranking sites generate higher user trust.
Disadvantages:
- Long timeframes — SEO requires time to deliver results.
- No guarantees — changes in search engine algorithms can affect site rankings.
- Technical complexity — successful SEO requires significant website improvements.
Conclusion
SEO is a comprehensive set of activities aimed at improving a website's visibility in search engines. It involves working on the site's technical foundation, content, and external factors. SEO offers benefits such as long-term results and targeted traffic acquisition, but it also requires time, effort, and continuous monitoring.
