SEO from Basics to Advanced
When we hear the word SEO, many associate it directly with "being on Google." That perception is accurate but also limited: SEO, or Search Engine Optimization, refers to the work done to optimize a website so that it is interpreted and displayed correctly and advantageously by search engines.
Imagine Google, Bing, or Yahoo as huge digital libraries. All sites, pages, and content are books that search engines are cataloging. If the "book" (the site) lacks a title, index, organized cover, or well-structured chapters, it will be much harder to find on the shelf. SEO is precisely what creates the structure that helps search engines catalog and prioritize content.
Optimization involves technical aspects, content quality, and authority, which together determine final ranking. That's why we discuss "SEO from basics to advanced": it begins with simple steps, such as writing a good title. It evolves into complex practices, such as data analysis, strategic link building, and continuous monitoring, utilizing specialized tools.
New Ways of Searching on Google
The way users search has undergone significant evolution in recent years. Previously, typing one or two words was enough. Today, searches are conversational and close to spoken language. A user might ask, "What is the best running shoe for asphalt?" rather than simply typing "running shoe."
This new way of queries means SEO must follow the evolution of search. Pages that rank well today are those that not only mention isolated keywords but also answer questions, provide context, and go in-depth on the topic.
It is also essential to understand how Google organizes results on the SERP (Search Engine Results Page). The ten blue links still exist, but they coexist with ad blocks, local results, images, videos, featured snippets, and even direct answers provided by AI. Being present on the SERP requires understanding each format and preparing content to fit those possibilities.
SEO and Paid Traffic: Understanding the Differences
A common question is: if I can advertise on Google Ads and appear at the top, why bother with SEO?
The answer lies in the nature of traffic. Paid traffic is like "renting a house": while you pay, your ad appears. When the investment stops, the traffic ceases immediately. SEO is like "building a house": it takes longer, requires structure, but once established, it continues to bring visitors consistently.
Key differences between paid traffic and SEO:
→ Speed of results: Ads bring immediate access; SEO takes weeks or months to mature.
→ Cost-effectiveness: Paid traffic is ongoing; SEO requires an initial investment but reduces costs over the long term.
→ Authority: Ads do not increase organic reputation; SEO strengthens brand authority.
→ Sustainability: SEO generates recurring traffic even without new investments.
In practice, the two work together. Paid traffic is excellent for fast campaigns and immediate sales, while SEO establishes a solid digital presence.
Technical SEO and Performance
At the heart of SEO is the technical side, which optimizes site performance and ensures search bots can read and interpret pages. The first pillar, as a ranking factor, is HTTPS, which Google requires as a security protocol that protects data.
Another fundamental point is performance. Users won't wait for slow pages, and Google is aware of this. That is why it created the set of metrics known as Core Web Vitals, which measure:
→ LCP (Largest Contentful Paint): time until the most significant visible element loads.
→ INP (Interaction to Next Paint): responsiveness to clicks or interactions.
→ CLS (Cumulative Layout Shift): layout stability, preventing buttons and text from "jumping" on the screen.
To monitor these factors, tools like the Pagespeed report help identify bottlenecks. Best practices to improve performance include image compression, using lightweight formats such as WebP, minifying CSS and JavaScript, cache-control for resource reuse, and optimized servers.
One important detail: performance is not only technical, it's also user experience. The more fluid and fast the navigation, the longer users stay on the site and, consequently, the more positive signals Google captures for ranking.
Keywords and Content Structure
Every SEO strategy starts with keyword research. These keywords are the terms users type (or speak) into searches. Finding them requires tools like Semrush, which show search volume, competition, and semantic variations.
However, it's not enough to pick a word and repeat it many times in the text. You must create a clear semantic structure. The H1 should carry the primary keyword, H2’s address derived topics, and within them, H3’s and H4’s can detail specific aspects.
A good SEO text answers the user's questions. It's not just about placing words but about building a narrative that guides the reader—the richer and more useful the content, the greater the chances of standing out in the SERP.

SEO for E-commerce
E-commerce is fertile ground for SEO, which aims for a better browsing experience. Each product represents a page, and if those pages are not well optimized, they can get lost among millions of competitors.
The product name must be clear and include the main keyword. Additionally, descriptions need to be rich, not merely listing features but answering common customer questions.
Example:
A "Asics Gel Nimbus Running Shoe" should have a description explaining who it's for, what differentiates it, whether it's better for long races or short training, which type of ground it suits best, etc. The more detailed, the higher the chance of attracting clicks and conversions.
Another crucial point in e-commerce is image optimization: images must be lightweight but high quality, always accompanied by descriptive ALT attributes. Additionally, applying structured data is vital so that information such as price, reviews, and availability appears directly on the SERP.
Finally, do not forget marketplaces. A product can gain much more visibility if properly categorized in comparators such as Google Shopping, which function like global storefronts.
SEO for Content Publishers
While e-commerce focuses on products, content publishers aim to build authority and engagement. A good article needs to combine the primary keyword, related terms, and an engaging narrative.
A common mistake is believing that just writing a lot guarantees ranking. Length matters, but quality is more decisive. A 2,000-word article can outperform a 5,000-word one if it is more focused, up-to-date, and valuable to the reader.
Also, links are fundamental. Internal links direct users to other site content, creating a relevance network. External links that point to authoritative sources increase credibility and indicate to Google that the content is well-referenced.
Publishers should always consider the reader's experience. Structuring short paragraphs, using clear subheadings, and inserting practical examples help maintain interest. The ultimate goal is always the same: to be the best possible answer to the user's query.
Status Codes, Redirects and Indexing
Behind the user experience lies the technical side that ensures pages work correctly. And there, it's where status codes come into play.
→ 200: Page loaded successfully; ideal response for indexing. → 301: Permanent redirect; preserves the relevance of the previous URL. → 302: Temporary redirect; used in tests or limited campaigns. → 404: Page not found; should be monitored so it doesn't harm navigation. → 503: Indicates maintenance; prevents the site from being deindexed when it cannot respond properly.Main codes and their uses:
Additionally, sitemaps (in HTML and XML) work as maps that guide crawlers, showing which pages they should prioritize. Taking care of indexing ensures that all content and optimization efforts actually translate into visibility.
SEO: beyond pre-established techniques
SEO is much more than a set of techniques: it is the foundation of any business's digital presence. It begins with simple details, such as a well-written title, but evolves into robust strategies that involve performance, authority, and user experience.
For e-commerce companies, this means carefully cataloging products, applying structured data, and competing on marketplaces. For content publishers, it means writing deep, helpful, and well-organized articles.
The significant advantage is that while paid traffic depends on continuous investment, SEO builds a solid base of sustainable organic traffic that grows over time and strengthens the brand.
By correctly applying the SEO practices presented in this guide — from technical performance to strategic content — any digital business can secure a prominent position on the SERP and convert visits into tangible results.
How Search Engines Work
Search engines like Google and Bing operate based on three major stages: crawling, indexing, and ranking.
→ Crawling is the process by which bots traverse pages and links, collecting information.
→ In indexing, those data are organized and stored in huge repositories, ready to be consulted.
→ Finally, in ranking, complex algorithms evaluate hundreds of factors to decide the order in which results appear on the SERP.
Explaining this is important because many believe that simply publishing content is enough to appear automatically. In practice, without proper indexing, a page simply doesn't exist to search engines.
Search Intent and SEO
Another fundamental concept is search intent. It's not enough to know which words people type; you must understand what they actually want to find. Intent can be:
→ Informational: when the user wants to learn or understand something, like "what is SEO."
→ Transactional: when the user intends to buy or hire, like "buy running shoes online."
→ Navigational: when the user already knows where they want to go, like "Facebook login."
Producing content aligned with search intent is what separates pages that attract visitors from pages that actually convert. Moreover, each type of intent influences SERP positioning: informational content tends to appear in articles and blogs, transactional searches prioritize product or service pages, while navigational queries highlight specific brands. Understanding this logic is essential to occupy the correct position at the right time.
Information Architecture and Site Structure
Good SEO is not only about optimized text. Information architecture ensures that users and bots navigate with clarity. Which involves:
→ Organized menus: they act as the site's main map. They should be clear, intuitive and group contents logically, avoiding too many options.
→ Friendly URLs: short, descriptive and easy-to-read addresses (e.g., site.com/products/cars instead of site.com/?p=123). They help both users and Google understand the content.
→ Breadcrumbs: the "navigation trail" that shows the user's position in the structure (e.g., Home > Products > Cars). This trail improves experience and facilitates crawling.
→ Logical hierarchy of categories and subcategories: organizing content into well-defined levels, like shelves. Example: Store > Clothing > Men > T-shirts. This logic makes the site scalable and easier to find.
→ Pages accessible in a few clicks: the fewer clicks a user (or Googlebot) needs to reach content, the better. This reduction avoids "hidden" pages and improves both UX and SEO.
In e-commerce, poorly structured categories can prevent products from appearing in the correct results. In blogs, lack of organization can cause good articles to get lost among hundreds of unrelated posts.
Link Building and Authority
SEO goes beyond on-page actions. Google also evaluates external signals which evolves to link building — the practice of earning links from other sites that point to yours. Each link acts like a vote of confidence: the more relevant sites reference your content, the greater your domain authority.
It's not about quantity but quality. A link from a widely-read newspaper is worth far more than dozens of links from low-quality blogs. That's why artificial practices like buying backlinks can bring more risks than benefits.
Measurement and SEO Monitoring
No SEO strategy is complete without measurement. Tools like Google Analytics and Search Console are indispensable to track results and validate whether applied efforts are delivering return.
In Analytics you can observe metrics such as number of visitors, top pages, average session duration and bounce rate. These data help understand user behavior: which content attracts more, where users drop off, and which pages generate more engagement.
Google Search Console shows how Google sees the site. There you monitor which pages are indexed, for which queries they appear, click-through rate (CTR) in search results and coverage errors that can harm ranking.
More than watching numbers, continuous analysis allows turning data into action. For example:
→ Pages with high traffic but low conversion may need content or CTA adjustments.
→ Optimize keywords that generate impressions but few clicks with more compelling titles and meta descriptions.
→ Revisit content with low dwell time to improve user experience.
This practical view prevents SEO strategy from being static. By tracking indicators frequently you identify optimization opportunities, test changes and ensure constant ranking improvement without needing overly complex or deep reports.
Mobile SEO and Accessibility
Today, over 60% of Google searches come from mobile devices. Therefore, having a responsive site is no longer optional it is a requirement. Pages that do not adapt to mobile lose positions.
Besides responsiveness, accessibility is increasingly relevant, which includes appropriate color contrast, alt text on images, keyboard navigation and content readable by screen readers. An accessible site serves more people, improves experience and sends positive quality signals.
Reinforced Conclusion
SEO is much more than a set of techniques: it is the foundation of any business's digital presence. It begins with simple details, like a well-written title, and evolves into robust strategies involving performance, authority and user experience. Monitoring speed metrics with Pagespeed, avoiding server errors such as "5XX" and continuously adjusting content according to SERP positioning are practical actions that ensure ongoing relevance.
For e-commerce, this means registering products carefully, applying structured data and competing on marketplaces. For publishers, it means writing deep, practical and well-organized articles.
The significant advantage is that while paid traffic depends on constant investment, SEO builds a solid base of sustainable organic traffic that grows over time and strengthens the brand.
By correctly applying the SEO practices presented in this guide — from technical performance to strategic content — any digital business can secure SERP space and turn visits into tangible results.
