SEO, simply.

If you want to know what SEO is in plain words, it is the work that makes a website show up in search more often and bring in customers without paying for every click. Below we go through the basic concepts of SEO without jargon: how search works, what affects rankings and where a business owner should start.

This piece is meant as SEO for beginners: after reading it, it is easier to speak the same language as your contractor and understand what you are paying for.

SEO is not magic, it is work with search

SEO is search engine optimization, that is, work on a website so that search engines consider it the best answer to a query. SEO promotion is made up of technical fixes, useful content and an online reputation. In essence, it is optimization for search engines, the main one in Russia being Yandex with a share of about 70%, followed by Google.

How a search engine decides whom to show

Hundreds of signals are taken into account: text, speed, usability, visitor behavior, links. Yandex and Google do not disclose in detail how search engines choose websites, but the principle is known: the winner is the page after which there is no need to go back to search.

What the user sees in the results

Search results are the page of results for a query. Besides links, they include maps, products, videos and AI answers: in Alice AI they appear for about 42% of queries, and sources are taken almost exclusively from the top 10. Organic results and ads look similar, but they work differently.

Organic results

These are free positions that the search engine allocates on its own. You cannot buy a place here, you can only earn it with the quality of your website.

Ads

Ads are labeled with the word "Ad," the advertiser pays for every click, and impressions stop when the budget runs out. We compared both channels in the article SEO or contextual advertising: which to choose.

How search works

How search works is easiest to explain in three steps: a robot finds the page, the system saves it to its database, and an algorithm decides in which position to show it. If a website stumbles at any step, it will not reach the user.

Crawling websites

Robots travel the internet via links and sitemaps. Crawl frequency depends on the size of the site, updates and server speed, and the IndexNow protocol in Yandex and Bing helps speed it up.

Indexing

The page is analyzed and added to the search engine's database. Google takes into account only the first 2 MB of HTML code, so heavy templates with embedded scripts sometimes lose part of their content.

Ranking

For a query, the algorithm selects suitable documents and sorts them by relevance, quality and usability. This is the answer to how a search engine ranks pages, and the regional adjustment explains why results differ from city to city.

What an index is

An index is a catalog of all pages known to the search engine. Only documents from it make it into the results, so any analysis starts with the question of how many of the site's pages are in it.

Why a website may not get into the index

The obstacles are a block in robots.txt, the noindex meta tag, duplicates, server errors and empty pages. Since March 2025, Yandex has considered AI-generated texts without expert proofreading to be of low value. How to find such problems is described in the article technical website audit: what to check first.

What affects rankings

What affects search rankings: the technical condition, how well the content matches the query and the authority of the website. The weight of the factors depends on the niche, but a failure in any of them drags the whole project down.

Technical condition of the website

Google assesses usability by Core Web Vitals: LCP up to 2.5 s, INP up to 200 ms, CLS no higher than 0.1 for 75% of real visitors. Indexing is based on the mobile version, so errors on the phone cost you rankings.

Content and queries

Each page answers its own group of queries. Someone searching for "laptop repair price" expects a price list and timelines, not the history of laptops.

Links and mentions

Links from authoritative websites on similar topics work like recommendations. The weight of brand mentions in reviews, the media and on forums is also growing, and neural networks read them too.

On-site factors

Everything that depends on the website owner:

• the structure of sections and navigation;
• headings, title and description;
• texts, photos, prices, specifications;
• internal links;
• speed and the mobile version.

Off-site factors

Links, mentions, reviews on maps, how people behave in search results. You can influence them only indirectly, which is why they are dealt with after putting things in order on the website itself.

How SEO differs from advertising

Advertising buys attention right away, while SEO builds a flow of visitors that does not disappear once you stop paying.

Speed

Ads bring people on the day of launch. The first shifts from optimization are visible after 2-3 months, and a sustainable result after 6-12.

Cost

In advertising you pay for every click, which in competitive niches means hundreds of rubles. In SEO the money goes to the specialists' work, while clicks are free, so the cost per visitor falls over time.

Long-term effect

A page in the top brings traffic for months with minimal maintenance. It makes more sense to treat optimization as an investment in an asset rather than a one-time expense.

When SEO is not needed

When a product has a short lifespan: a seasonal sale, a one-off event, testing a niche. A new product that nobody is searching for yet is also promoted with ads and social media.

When you cannot do without SEO

If customers search for your services regularly: stores, medicine, lawyers, repairs, business services. An example is the case about 1,000 leads from search.

What SEO work consists of

Of three pillars: technical optimization, semantics and content. Without any one of them, the other two will not deliver results.

Technical optimization

Checking indexing, eliminating duplicates and errors, setting up robots.txt, sitemap, canonical and redirects, speeding up loading. This is the foundation of the project.

Semantics

A semantic core is customer queries distributed across pages: hundreds of phrases for a service company and tens of thousands for a store. You can start with the guide how to choose keywords for SEO.

Content

Texts, photos, prices, answers to questions. A draft from a neural network is acceptable, but before publication an expert checks it and adds facts from practice.

Search optimization

This is the name for everything that makes a page understandable to a robot: headings, meta tags, structured data, internal linking. In this sense, search SEO optimization is almost invisible to the visitor.

Optimizing for SEO

Optimizing for SEO also takes the person into account: a visible request button, clear prices and quick answers improve behavioral signals, and rankings follow.

Common SEO myths

Most disappointments are caused not by poor work but by false expectations.

"Top in a week"

A page needs to get into the index and build up trust; doing this in a week is realistic only without competitors. Manipulating behavioral factors ends in penalties.

"Guaranteed rankings"

Algorithms change several times a year, and nobody outside Yandex and Google controls them. A promise of a "guaranteed top 3" means either queries with no demand or a lack of understanding of search.

"SEO is dead"

The myth comes back to life with every change in search results, most recently with AI answers. But neural networks take information from websites in the top, so classic optimization has become the foundation for them too.

What can realistically be promised

Whatever depends on the contractor:

• a plan and timeline of work by month;
• growth in visibility for agreed queries;
• trends in traffic and inquiries;
• clear monthly reports;
• the client holding access to all accounts.

What cannot be promised

A specific position by a certain date, a number of sales and a "permanent" result without maintenance. Other warning signs are in the article how to choose a contractor and not fall into the promise trap.

Where to start

With diagnostics, not with texts and links. It takes 1-2 weeks and shows why your particular website needs optimization.

Check the website

Connect Yandex Webmaster and Search Console, assess the number of pages in the index, errors and queries with impressions. The "Site visibility in Alice AI" report shows whether the neural network cites you.

Collect queries

Write down how customers name your services, check search volume in Wordstat and split the phrases into commercial and informational: the former lead to service pages, the latter to the blog.

Look at competitors

Compare sections, prices, reviews and calculators with the top ten. Whatever you lack but all the leaders have is the first improvement to make.

SEO specialist

An in-house SEO specialist is justified in a large project. For a small business an agency is more cost-effective: for the same money, you get an SEO specialist, a copywriter, a developer and an analyst.

Search engine optimization

Search engine optimization is not an off-the-shelf product; you cannot buy SEO once and for all. The price of SEO promotion depends on the niche and the scope of work, and the initial SEO optimization of a website is usually estimated separately. When you decide to order SEO promotion for your website, compare contractors by the scope of work, not just by the price of SEO optimization.

Conclusion

SEO makes a website understandable to search engines and useful to people. It is slower than advertising, but it delivers a flow of customers that does not drop to zero along with the budget.
