Introduction
Every day Google processes over 8.5 billion queries. Behind each of them is a person with a specific need – looking for a product, comparing services, wanting an answer to a question. If your website does not appear in those results, then for those people you simply do not exist. SEO is the process that changes that.
The data is unambiguous: 53% of all web traffic comes from organic search (BrightEdge), and organic results generate over 1,000% more traffic than organic social media. Even so, 96.55% of all pages on the internet receive not a single visitor from Google (Ahrefs). The difference between sites that attract clients and those that sit empty is not a matter of luck – it is a matter of SEO.
This article is the pillar of our series of SEO resources. It explains what SEO is, how it works and what elements it consists of, and for each specific aspect (technical integration with web design, the intersection with CRO, practical application by page type) it points you to the specialised cluster articles. We will show how SEO connects directly to whether your website generates clients or simply takes up space on the internet.
What SEO is: a definition in plain language
SEO (Search Engine Optimization) means optimisation for search engines. It is the set of actions that make your website more understandable, more useful and more authoritative in the eyes of Google (and other search engines), so that it appears higher in the results when potential clients search for something related to your business.
In the simplest terms, SEO means building your site so that when someone types “website development” or “online clothing store” into Google, your website shows up among the first results – without you paying for advertising.
An important clarification: SEO is not a trick or a hack. It is a long-term strategy for building visibility, trust and authority in the digital space. Google ranks higher the sites that genuinely help users, and penalises those that try to manipulate the algorithm. Good SEO and a good website go hand in hand – which is why at CreateWeb we treat SEO not as an add-on service, but as an integral part of building every site.
Why SEO matters: the numbers behind visibility
Let us start with the fact that explains everything: the first position in Google receives on average 39.8% of all clicks for a given query (First Page Sage, 2026). The second – 18.7%. The third – 10.2%. By the tenth position the figure falls below 2%. On the second page – practically zero.
This means the difference between position 1 and position 11 is not “a little more traffic” – it is the difference between visibility and invisibility.
Google holds 89.85% of the global search market (StatCounter, March 2026). When we talk about SEO, we are mainly talking about Google – that is where the people are and where the traffic is. SEO generates an average return of 748% – for every dollar invested, an average of $7.48 comes back (SearchLab, 2026). For comparison, paid ads in Google Ads have an average conversion of 2.1% at a CTR of 1.4-2.1% for the top positions, while the organic first position attracts 39.8% of the clicks.
SEO leads have a close rate of 14.6%, while with outbound marketing (cold calls, direct mail) that rate is 1.7%. People who find you themselves through Google are incomparably more motivated than those you push your message onto.
61% of small businesses still do not invest in SEO (WordStream, 2026), but 71% of those who do invest report a significant increase in traffic. This is simultaneously a worrying and an encouraging statistic – worrying because the majority are falling behind, and encouraging because the opportunity is enormous for those who act.
How Google works: the three phases of search
To understand SEO, you need to understand how Google decides what to show the user. The process goes through three phases, each of which can be blocked by errors on your site.
Phase 1 – Crawling. Google uses automated programs called bots or crawlers, which continuously traverse the internet, following links from page to page. When Googlebot reaches your site, it reads the HTML code, the text, the images and the structure. If there is a technical problem – slow loading, broken links, a blocking robots.txt – the bot cannot do its job and your pages stay invisible.
Phase 2 – Indexing. After the bot has read the page, Google adds it to its index – a giant database with billions of web pages. Indexing means Google knows your page exists and what it contains. But indexing does not mean ranking – a page can be in the index and still sit at position 500 for a given query.
Phase 3 – Ranking. When a user types a query, Google compares the pages in its index and orders them by relevance, quality and authority. The algorithm uses hundreds of factors – from the page content and loading speed to the number and quality of backlinks. The goal is to show the user the most useful, most accurate and most reliable result. SEO is the process by which you help Google understand that your page is precisely that result.
An SEO pyramid of priorities: where to start
SEO looks vast – hundreds of factors, constant algorithm changes, dozens of tools. But if you have a limited budget or limited time, not all efforts carry equal value. The following pyramid sets the order in which the work should be done: each level rests on the one before it, and without a stable foundation the upper levels do not work.
| Level | What it includes | Why it is a priority |
|---|---|---|
| 1. Technical foundation | Speed, Core Web Vitals, mobile-first, SSL, indexability, URL structure | Without this Google cannot reach or rank your site |
| 2. Information architecture | Sitemap, navigation, internal linking, canonical tags | If the user cannot find the content, nothing else matters |
| 3. Content and relevance | Keywords, search intent, quality content, structured data | This is where the competition for positions begins |
| 4. Authority (E-E-A-T) | Backlinks, brand signals, expertise, trust | This is where competitive keywords are won |
| 5. Continuous optimisation | Analysis, A/B tests, updates, expansion | This is what holds the position over time |
The typical mistake is to start from the top – aggressive link building or content in an industrial niche – before the technical foundation is stable. The result is an ineffective investment. If your site loads in 5 seconds, do not start with SEO copywriting – start with quality hosting and Core Web Vitals optimisation.
The three pillars of SEO
SEO is not one thing – it is an ecosystem of practices that work together. They divide into three main areas, each of which we cover in depth in specialised cluster articles.
Technical SEO: the foundation without which nothing works
Technical SEO guarantees that Google can physically reach, read and index your site. If there is a problem here, nothing else matters.
The main elements are loading speed (Core Web Vitals – LCP under 2.5s, INP under 200ms, CLS under 0.1), mobile-first optimisation, an SSL certificate (HTTPS), an XML sitemap, robots.txt, canonical tags, a clean URL structure and indexability. The intersection between technical SEO and design – how each of these decisions is set at the design stage – we cover in depth in our guide to SEO web design. Without quality hosting with a low TTFB, no amount of optimisation can compensate for a slow server.
When we build a site at CreateWeb, technical SEO is built in from day one – a clean HTML structure, correct meta tags, fast hosting, mobile-first design and SSL. This is a baseline requirement, not an extra service.
On-Page SEO: the content that Google and people evaluate
On-Page SEO is everything you do on the page itself – keywords, the title tag (up to 60 characters, with the keyword at the start), the meta description (155-160 characters with a call to action), the heading structure (H1, H2, H3), internal links, alt texts for images and Schema markup.
The title tag is perhaps the single most important on-page element – it directly affects CTR in the results. The meta description is not a ranking factor, but it significantly affects clicks. The heading structure serves as a guide for both the user and Google. Correct information architecture for the site – how pages are grouped and linked – determines crawl efficiency and topical authority.
Schema markup (structured data) gives Google additional context – for example, that a given page contains an FAQ, a product with a price, a recipe or an event. It increases the chance of rich snippets in the results, which raises visibility and CTR by up to 35%.
Off-Page SEO: the authority earned outside the site
Off-Page SEO is everything that happens outside your website. The main element is backlinks – links from other sites to yours. Google treats them as “votes of trust”: when an authoritative site links to your page, that is a signal that your content is valuable.
The quality of backlinks is incomparably more important than the quantity. A single link from a site with high Domain Authority can carry more weight than hundreds of links from low-quality directories. Links from spam sites, paid link networks or irrelevant domains can actively harm your ranking – Google has a dedicated algorithm (Penguin) that identifies and penalises manipulative link practices.
Natural backlink building comes from creating content that people want to share – useful articles, original data, tools. Beyond links, off-page SEO includes brand signals (mentions of the business online, even without a link), presence in Google Business Profile, client reviews and activity on social media.
Search intent: the key most businesses miss
The keyword is only half the story. What matters more is search intent – what the person typing it actually wants. Google increasingly assesses whether the content matches the intent, not just whether it contains the right words.
There are four types of search intent:
| Intent type | What the user wants | Example query | Which page wins |
|---|---|---|---|
| Informational | To learn, to understand | “what is SEO” | A comprehensive guide, article, video |
| Navigational | To find a specific site/brand | “createweb contacts” | The specific page directly |
| Commercial | To compare before buying | “best CMS platform” | A comparison article, a review |
| Transactional | Ready to act | “online store development price” | A service page, a quote |
The mistake is writing transactional pages that answer informational queries, and the reverse. If someone searches “how SEO works”, a commercial page for SEO services will lose the position to a guide that explains. Conversely – if someone searches “SEO services Sofia price”, a blog post about SEO theory will not convert.
In practice this means: before writing a page, check what Google shows in the top 3 positions for your keyword. If the results are guides, the intent is informational. If they are product pages – transactional. Adapt the format to the expectation.
E-E-A-T: trust as a ranking factor
Google uses the concept of E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) to assess content quality. This is not a direct algorithm, but a framework that Google’s quality raters use to review results – and that the algorithm learns from over time.
Experience means real, hands-on experience with the subject. An article on restaurant management written by someone who has never worked in a restaurant is rated lower than an article by a practising restaurateur. Google looks for signals of first-hand experience – specific examples and nuances that only a practitioner knows.
Expertise is formal qualification. For YMYL topics (Your Money, Your Life – finance, health, law) expertise is critical. An article on treating diabetes written by a doctor with publications ranks significantly higher than an anonymous article on a general site. For a practical business this means: show the authors, their qualifications, connect the content to real experts.
Authoritativeness is the reputation of the brand and the author within the industry. It is measured through backlinks from respected sources, media mentions, awards and citations. Authority is built over years and is the hardest element of E-E-A-T.
Trustworthiness is the most critical of the four. It covers the accuracy of the information, transparency (clear contacts, terms, policies), site security (HTTPS, data protection) and honesty (no misleading claims or hidden advertising).
For a practical business owner E-E-A-T means: show who is behind the business (real names, qualifications, photos), demonstrate experience (portfolio, case studies, testimonials with concrete numbers), keep content current and accurate, provide clear contact information and transparent terms. After the Helpful Content Updates and the arrival of AI Overviews, E-E-A-T went from a “useful recommendation” to a “critical ranking factor” – especially for YMYL and B2B segments. Regular site analysis identifies weak E-E-A-T signals before they cost you positions.
SEO and AI: what changed in 2026
Search is transforming. AI Overviews (the AI-generated answers at the top of Google) appear in up to 13% of queries (Digital Applied, 2026), and AI search as a whole has grown by 527% in a single year (Semrush). This changes the rules of the game in several ways.
Organic CTR falls significantly when Google shows an AI Overview. A Seer Interactive study shows a drop of 61% – from 1.76% to 0.61% for queries with an AI answer. This means part of the traffic that used to be distributed among the organic results now stays inside Google. The user gets an answer without clicking anything.
But here is the key point: AI Overviews cite sources. Sites with higher authority, better structure and more useful content have a significantly greater chance of being cited. Good SEO does not lose value in the AI era – it transforms from “ranking the page” into “presence in the AI answers”. In practice this means: write short, direct answers at the start of sections, structure the content with clear H2/H3, use FAQ schema, and offer original data and opinions that models cannot synthesise from elsewhere. We cover the evolution of websites with AI in a separate article.
For the practical owner the SEO basics stay valid – a fast, mobile-optimised site with quality, structured content. But the focus shifts: from “position #1 for a keyword” to “the most useful, most cited, most structured answer to the user’s question”.
How long SEO takes
One of the most common mistakes is expecting an instant result. SEO is not paid advertising – you do not flip a switch and get traffic tomorrow. Most businesses start to see measurable results after 3-6 months, and stable, sustainable growth comes between 6 and 12 months.
Only 1.74% of newly published pages reach the Google top 10 within one year (Ahrefs). That sounds discouraging, but there is important context: those 1.74% are out of all pages – including the millions created with no SEO thought at all. Sites that follow good practices from the very start have incomparably better chances.
Factors that affect the speed: domain age (older domains have an advantage), competition for the target keywords, the quality and quantity of existing content, the technical health of the site, and the pace of backlink building.
The good news is that SEO results compound. Unlike advertising, where traffic stops when you stop paying, organic traffic keeps growing as long as you maintain the content and the technical condition of the site. That is also why SEO has a 748% ROI – the investment generates value long after it was made.
Basic SEO versus a full SEO strategy
A clear distinction between the two matters, so that you have realistic expectations and know exactly what you are buying.
Basic SEO is what every quality site should have from the moment it launches – technical optimisation, a correct structure, meta data, speed, a mobile version, alt texts, an XML sitemap, indexability. This is the foundation without which everything else is pointless. It is laid at the website development stage, not after the fact.
A full SEO strategy is an ongoing process that includes in-depth keyword research and competitor analysis, creating and optimising content (blog articles, landing pages, product descriptions), backlink building, technical audit and monitoring, data analysis and iteration. This requires a specialised SEO team and continuous commitment – usually monthly.
The intersection between SEO and conversion rate optimisation (CRO) is a separate strategic topic. The conversion optimisation process itself – from data analysis and heatmaps to A/B testing and specific strategies – we cover in our full guide to conversion rate optimization, which also has a detailed section on how SEO and CRO work together.
At CreateWeb we guarantee that every site we build has full basic SEO from day one – with a clean technical foundation, a correct structure and all the necessary on-page elements. If you later decide to invest in a full SEO strategy with a specialised partner, your site will be ready for it without the need for expensive rework.
Local SEO: when your clients are nearby
For businesses with a physical location – restaurants, clinics, law firms, hair salons – local SEO is often more important than general SEO. When a user searches “dentist Sofia” or “hairdresser Plovdiv”, Google shows a map with three results (the “Local Pack”) above the organic results.
To appear in the Local Pack you need an optimised Google Business Profile (correct name, address, phone, opening hours, category), positive reviews from real clients, consistent NAP (Name, Address, Phone) information across all online directories, and a website with local signals – the address on the page, an embedded Google Maps map, mentions of the neighbourhood or city.
Local SEO is one of the areas where quality web design makes a big difference. A site with an embedded map, a click-to-call button on mobile, structured data for LocalBusiness schema and a page with clear contact information is far more competitive than a site that merely exists. Different industries require a different approach – we cover that in the article on web design by industry.
Analysis and measurement: SEO without data is guesswork
SEO is not a project with a beginning and an end – it is a continuous process of measurement, analysis and improvement. Without data every decision is a guess, and guesses rarely lead to optimal results.
Google Search Console shows which queries bring traffic to your site, what the CTR is, which pages are indexed and what technical problems Google sees. Google Analytics 4 provides a detailed picture of user behaviour – where visitors come from, what they do on the site, where they leave. PageSpeed Insights analyses performance and gives specific recommendations. We cover Google tools and the best website analysis tools in specialised articles.
The key metrics to track are organic traffic by page and keyword, position in the results for priority queries, CTR from Search Console, bounce rate and average session duration as indicators of relevance, and the conversion rate as the final business metric. Regular site analysis is the basis of every informed SEO decision.
5 SEO mistakes we see on the Bulgarian market
After working on hundreds of projects, these are the most common and most expensive mistakes among Bulgarian businesses.
A site with no SEO foundation at all during development. A structure created on an arbitrary basis, with no research into what potential clients are searching for. The result is a site with 5-10 beautiful pages that receives not a single visitor from Google. The fix: make SEO part of the project brief, not a follow-up service.
Cutting costs on hosting. Saving BGN 10 a month on hosting can cost thousands in lost traffic. A TTFB above 800ms is a problem no amount of on-page optimisation can compensate for. The fix: fast hosting with a CDN is an investment that pays back from the first week.
Keyword stuffing. Texts in which “website development” is repeated 40 times in 500 words do not simply fail to help – they actively harm. Google recognises the manipulation and penalises the page. The fix: write for people, not for bots; a natural keyword density of 0.5-1.5%.
A one-off approach to SEO. Many businesses treat SEO as a one-off project – “we did the SEO, it is done”. Algorithms change, competitors optimise, content ages. Without regular maintenance the results degrade.
Ignoring search intent. Writing informational content when the search is transactional, and the reverse. The fix: before writing a page, check what Google shows for the top 3 results for your target keyword.
A practical checklist: the SEO minimum for every site
If you need to take one practical list away from this whole article, here it is.
Technical SEO: fast hosting with a TTFB under 200ms, an SSL certificate (HTTPS), responsive mobile-first design, Core Web Vitals in the green (LCP under 2.5s, INP under 200ms, CLS under 0.1), an XML sitemap submitted in Google Search Console, a clean robots.txt, a correct URL structure with descriptive addresses.
On-Page SEO: a unique title tag for every page (up to 60 characters, with the keyword), a unique meta description (155-160 characters), one H1 per page with the keyword, a logical H2/H3 structure, alt texts for all images, internal links between related pages, Schema markup (at least Organization, Article/FAQ).
Content: texts written for people (not for bots), a focus on the real questions of the target audience, alignment with search intent, regular updating of existing content, a clear pillar to cluster hierarchy.
Off-Page SEO: a Google Business Profile (if you have a physical location), natural backlinks from quality sources, consistent NAP information in online directories, brand presence in industry media.
Monitoring: Search Console and GA4 set up and actively reviewed, a monthly review of key metrics, a quarterly in-depth audit.

Frequently asked questions
What is SEO in simple terms?
SEO (Search Engine Optimization) is the process of optimising a website so that it appears higher in Google results when potential clients search for related products or services. The goal is to attract visitors from organic (free) search, without paying for advertising.
What is search intent and why does it matter?
Search intent is what the user actually wants when they type a query – to learn, to find a specific site, to compare before buying, or to buy now. Google increasingly assesses whether the page matches the intent, not just whether it contains the keywords. Before writing a page, check what Google shows in the top 3 positions for your target query.
What is the difference between basic SEO and a full SEO strategy?
Basic SEO is the technical and on-page foundation laid during website development – speed, structure, meta data, Schema, mobile optimisation. A full SEO strategy is an ongoing process with keyword research, content creation, link building and continuous analysis. The first is a one-off investment at build time; the second is a monthly commitment with a specialised team.
SEO or paid advertising – which is better?
They are not mutually exclusive – they complement each other. SEO generates long-term, sustainable traffic with a 748% ROI and a high conversion rate (14.6%). Paid advertising gives immediate traffic, but stops when you stop paying. For most businesses the optimal approach is SEO as the foundation and paid advertising to accelerate at the start or for specific campaigns.
What is E-E-A-T and how does it affect ranking?
E-E-A-T is the framework Google uses to assess content quality: Experience, Expertise, Authoritativeness, Trustworthiness. After the Helpful Content Updates and AI Overviews, E-E-A-T is a critical factor, especially for YMYL topics (finance, health, law) and B2B segments.
Do AI Overviews kill SEO?
No, but they transform it. AI Overviews cite sources, and sites with higher authority and better structure have a significantly greater chance of being cited. Good SEO does not lose value – the focus shifts from “position 1 for a keyword” to “the most cited source in the AI answers”.
What is the most effective first SEO move for an existing site?
Start with a technical audit through Google Search Console and PageSpeed Insights. Fix the critical technical problems (speed, CWV, mobile optimisation, indexability) before investing in content or link building. Experience shows that 60-70% of lost positions on Bulgarian sites are recovered through technical optimisation alone, without writing any new text.
Conclusion
SEO is not magic, it is not a technical mystery and it is not something to think about “later”. It is a fundamental element of every successful website – the process by which your potential clients find you when they need exactly what you offer.
The data speaks clearly: 53% of web traffic is organic. The first position receives 39.8% of the clicks. SEO leads close 8 times more often than traditional marketing. And 96.55% of pages receive not a single visitor from Google – simply because they are not optimised.
At CreateWeb we believe that a good site is an SEO-optimised site by default. That is why basic technical SEO is integrated into every project of ours – from corporate websites to online stores. For a personalised quote or a free consultation, ask the CreateWeb team – an SEO-ready site is not a luxury, but a baseline standard.
