What is SEO? Four pillars, myths and measuring results

What is SEO? The short answer

SEO stands for Search Engine Optimization. In practice, it is everything you do on and around your website to make Google show it higher in unpaid results for the questions your customers ask.

Unpaid is the important word. Nobody pays Google for a click on an organic result. You pay for the work that makes that result appear in the first place.

SEO is not one action. It is four kinds of work that need to fit together:

• technical - so the search engine can load, understand and index the website,
• on-page - so a specific page answers a specific question,
• content - so there is something to answer with,
• off-page - so other websites confirm you are worth trusting.

Below, we break each area into practical tasks, explain how search engines select results, show which popular “SEO rules” have been outdated for over a decade and describe what to check in reports.

How a search engine chooses results

Without this part, the rest sounds like magic. Google does three things, one after another.

Crawling. A bot moves through the web, fetching pages and following links. If no link points to your page and it is absent from the sitemap, the bot simply does not know it exists. The robots.txt file can block access, sometimes accidentally when a site is moved from a test environment to production.

Indexing. A fetched page enters a huge catalogue: what it is about, its headings, what the content means and what it relates to. A page can be crawled but not accepted into the index because it duplicates another page, is empty or carries noindex. Search Console then shows “Crawled - currently not indexed”.

Ranking. Only now, a fraction of a second after a query is entered, does the system arrange the results. It considers hundreds of signals: how content matches the query’s intent, quality and freshness, incoming links, domain history, the searcher’s location and device.

There is no single “Google algorithm” to crack. There is a set of systems receiving several thousand changes each year, counting everything from small adjustments to more than a dozen larger updates that actually reshuffle results.

Those three steps remain the same, and most problems we find in an SEO audit lie in the first two, not the third.

The four pillars of SEO

Technical SEO

This is where things live that customers do not notice until they stop working. The site takes 5 seconds to load on a phone and half the visitors leave before their first scroll. A store generates 400 filter URLs, each a separate version of the same product list. Old addresses return 404 after a migration, and rankings built over two years evaporate.

The work is specific: sitemap, robots.txt, 301 redirects, canonical URLs, mobile version, Core Web Vitals, structured data (schema.org), SSL certificate and directory structure.

On-page SEO

Optimising one page for one main query. The title in search results, one H1 heading, a sensible H2/H3 hierarchy, a URL without random IDs, image alt text and descriptive internal links instead of “see more”. A sentence containing the keyword should sound like a sentence, not a spreadsheet entry.

Content

Without content, there is nothing to rank. A service page with three vague paragraphs loses to one answering questions about scope, timing and price. Content also includes blog articles targeting informational terms, store category descriptions and FAQs in structured data.

Off-page SEO

A link from another website to yours is a vote. Google looks at who cast it: an industry publication carries different weight from a 2008 directory with 3,000 entries. Off-page work also covers Google Business Profile, customer reviews and consistent NAP citations: the same business name, address and phone number across the web.

SEO and pozycjonowanie: are they the same?

In Polish, these words are used interchangeably without correction. The distinction is practical rather than dictionary-based: SEO names the discipline and its tasks, while “pozycjonowanie” names the agency service you buy, spreading those tasks over months with agreed keywords, reporting and budget.

Put briefly, you do SEO and commission an SEO service. This article explains the former. To understand month-by-month cooperation and who it suits, read what website SEO as a service means.

What actually affects rankings

Google does not publish the weightings, but years of testing, leaked documentation and observation of thousands of websites show which factors move results most.

1. Matching search intent. Someone searching “what is SEO” wants an explanation, not an offer. A sales page will not beat an article even if every heading contains the phrase.
2. Content quality and depth. Material that covers the subject beats five pieces that only skim it. Whether the visitor returns to search results matters.
3. External links. Still one of the strongest signals. Twenty links from real, related websites carry more weight than a thousand from link farms.
4. Page experience. Loading speed, a stable layout, readability on phones and no pop-ups covering the content.
5. Local signals. For city-based queries and mobile searches, distance, profile completeness and reviews matter.
6. Domain history. A five-year-old website with a clean past starts from a better position than a domain bought yesterday.

Myths still circulating in the market

“You have to fill in meta keywords.” Google has ignored this tag since 2009. You leave your target keyword list in the code and gain nothing else. Competitors can see it too.

“The keyword must make up 2-3 per cent of the text.” There is no threshold to hit. Search engines recognise topics from context and related concepts. A phrase forced into every other sentence makes poor reading, and the data shows it: people leave after a few seconds.

“The website is SEO-friendly because the proposal says so.” That is an empty phrase. Ask specifics: does it render content without JavaScript, what is its mobile PageSpeed Insights score, does it have structured data, are the URLs readable? You can check the answers in five minutes.

“One round of optimisation is enough.” Competitors publish, Google updates systems and your offer changes. A website left alone for two years loses ground even if nobody has touched it.

“You just need lots of links.” A dozen or so good ones can be enough. Mass links from arbitrary places are the easiest route to an algorithmic penalty that takes months to recover from.

“Number one guarantees sales.” First place for a term nobody uses with buying intent brings traffic without enquiries. Choose terms for intent, not volume.

How to measure SEO results

Two free Google tools are enough to tell whether the work is helping.

Google Search Console shows data directly from search. Watch clicks rather than impressions, average position for specific queries, and terms in positions 8-20. Those offer the shortest route to growth: push them into the top five. Also check indexing reports to see how many pages entered Google’s catalogue at all.

Google Analytics 4 shows what happens after the click: organic traffic by landing page, the path to the form, submitted enquiries and phone calls. Without configured conversion events, everything else is just interesting trivia.

Metrics that can mislead:

• Search Console impressions rise by themselves when a website starts matching incidental long-tail queries. Without more clicks, it achieves nothing.
• Average position mixes your main term with a hundred long-tail terms. Always filter by a specific query.
• Bounce rate on a how-to article can be high because the visitor found the answer and moved on. That is not failure.
• The ranking in your browser is not the market ranking. Search history and location alter results. Check in private mode or Search Console.

A sensible reporting cycle is monthly, with first conclusions after a quarter. Earlier comparisons are noise.

Tools used in practice

The list is shorter than it looks from the outside. The first four tools are free and cover most daily work.

• Google Search Console - queries, clicks, indexing, errors. The foundation; without it, the rest is guesswork.
• Google Analytics 4 - on-site behaviour and conversions.
• PageSpeed Insights - Core Web Vitals and guidance on what slows loading.
• Google Business Profile - the foundation of local SEO, reviews and map visibility.
• Ahrefs or Semrush - keyword analysis, link profile, competitor research. Paid, starting at several hundred zlotys per month. Honestly, a separate licence rarely pays for a single business.
• Screaming Frog - a crawler for technical audits. It scans the entire site and lists duplicate titles, redirects and pages without content.

A tool will not create a strategy for you. It shows data. A person decides which keywords to target and what to improve first.

SEO or Google Ads: which should you choose?

Both channels lead to the same results page through different doors.

Ads deliver immediately and reveal which keywords bring enquiries, invaluable information for SEO planning. But they end with the budget. SEO builds more slowly and costs money without a return in the first months; the earned position continues working when you stop paying for the work.

For most businesses, a mix makes sense: Ads at launch and during peak seasons, SEO as a two-year foundation. Our pricing page lists the rates: SEO audits start at PLN 800, ongoing local SEO at PLN 1,500/month.

We explain what those amounts include and what determines the budget in how much SEO costs.

Summary: what to remember

SEO combines four areas: technical work, on-page optimisation, content and external links. Before tackling rankings, make sure the search engine’s first two steps work, because they contain most problems found in audits. The strongest contributors are matching search intent, covering a topic properly and gaining links from real, related websites, not keyword density or meta keywords, which Google has ignored since 2009. Check results in Search Console and Analytics monthly, drawing conclusions after a quarter, rather than using your own browser results. If choosing between SEO and Google Ads, the answer is usually both, in different roles.
