What is SEO optimisation? A guide for business owners

"We guarantee you the number one spot on Google." If an agency tells you that, you can hang up. That advice isn't ours, it's Google's. In its guidance on hiring an SEO, Google states plainly that no one can guarantee a number one ranking.

So what is SEO optimisation, and why does everyone who builds websites keep bringing it up? In short, it's the work of helping Google understand your site and show it to people searching for exactly what you sell. There's nothing magic about it. Below we explain how it works, how long it takes and what you can do yourself before you hire anyone.

What SEO optimisation means

SEO stands for search engine optimisation. Google's SEO Starter Guide describes it as helping search engines understand your content. In practice that comes down to three things: Google can find your pages, it understands what they're about, and it trusts them enough to show them above your competitors'.

Visitors who arrive this way are called organic traffic. You don't pay per click, as you do with Google Ads. You pay in time and effort: a good site, useful pages and patience. That's why SEO pays off best for businesses whose customers actively search: "dentist in Lozenets", "accountant for a limited company", "air conditioner repair Varna".

How Google decides which pages to show

Before a page can appear in the results, it goes through three stages:

• Crawling. Google's program (Googlebot) follows links and discovers new and updated pages. If nothing links to a page and it isn't in your sitemap, Google may never find it.
• Indexing. Google reads the text, headings, images and structure, then stores the page in its index. Not everything that gets crawled makes it in: duplicate or near-empty pages are often left out.
• Ranking. When someone searches, Google picks the most useful pages in its index for that query. It weighs the content, the searcher's language, device and location, and many other signals.

SEO optimisation works at all three stages. The technical side makes sure your pages get crawled and indexed. Content and authority decide where they rank.

The three parts of SEO optimisation

Technical foundations

This is the groundwork. The site loads quickly, works well on a phone, has a clear URL structure and a sitemap, and doesn't block Google by mistake. It also covers Core Web Vitals, Google's measures of page speed and stability. Plenty of WordPress sites lose ground here because of heavy themes and too many plugins. We cover the difference in Next.js vs WordPress for business websites.

Content

Google itself says useful content will likely influence your presence in search more than anything else in its guide. In practice, every important service gets its own page and every page answers a specific question. The page title and meta description should tell people exactly what they'll find if they click.

Authority and trust

This is the work that happens off your site: links from other respected sites, mentions in the press and in directories, reviews on your Google Business Profile. For a local business in Bulgaria, reviews and a complete Google listing are usually a better place to start than chasing links. Bought links from dodgy sites do the opposite. Google spots them and can push your rankings down.

What SEO optimisation isn't

SEO attracts plenty of myths, and some of them get expensive. These are the most common:

• It isn't a guaranteed top spot. An agency that promises a specific position either doesn't understand how search works or isn't being straight with you.
• It isn't a list of keywords. Google doesn't use the keywords meta tag. Repeating "cheap furniture Sofia" ten times in one paragraph only makes the text harder to read.
• It isn't a one-off job. Your competitors keep publishing, Google keeps updating its algorithms and your services change. SEO is more like servicing a car than a single repair.
• It isn't advertising. Google Ads brings visitors for as long as you pay. SEO keeps bringing them after that, but it takes longer to start working.

One more myth we hear a lot: "The site is new, so Google must like it." A new site still has to earn trust. If you replace an old site without redirecting the old URLs, you can even lose rankings it took years to build.

How long SEO optimisation takes

There's no fixed timeline, but there are benchmarks. Google says some changes show up in the results within hours, while others take several months. Technical fixes, such as slow pages or indexing errors, usually pay off fastest. New content and authority build up more slowly.

In our experience, a new site in a competitive niche rarely reaches page one for its main searches in the first few months. An established site that has simply been neglected on the technical side can improve much faster. If someone promises results "within two weeks", ask exactly what they'll do and how they'll measure it.

Where to start on your own

A lot of the basics don't need a specialist. If you already have a site, set aside an afternoon for this:

• Add your site to Google Search Console. It's free, and it shows which pages are indexed, which searches bring people to you and which errors Google sees.
• Fill in your Google Business Profile: address, opening hours, photos, categories. Ask happy customers for a review.
• Check your page titles. Each should be unique and say what you offer and where: "Small business accounting in Plovdiv", not "Home".
• Give every main service its own page rather than cramming them all onto one.
• Open the site on your phone and be honest with yourself. Does it load fast? Is the text readable? Is the call button easy to tap?

You'll find a fuller list in our small business website checklist. If the site still doesn't show up after these steps, the problem is usually technical, and that's when outside help is worth it.

SEO and AI search

Plenty of business owners ask whether SEO still matters now that Google shows AI Overviews above the results and some people search straight in ChatGPT. For its own AI features, Google is clear: there are no additional requirements and no special optimisation needed to appear in them. A page has to be indexed and meet the usual technical requirements, and the SEO fundamentals still apply.

If anything, AI search raises the bar. Clear answers, concrete facts and well-structured pages help Google understand your site, and the same things help language models quote it.

The verdict

SEO optimisation comes down to discipline: a technically sound site, a useful page for every service, and trust that builds over time. For most small businesses in Bulgaria the biggest gains come from the basics, not from elaborate strategies. Get those right first, then pay for more.

We build the basics into every site. On our marketing sites, schema markup, a sitemap and meta descriptions are there from day one. The monthly plan on our pricing page includes a monthly SEO and performance check. If you need regular content too, our AI content production service writes articles in Bulgarian and English that you approve before they go live.

Frequently asked questions

What is SEO optimisation in simple terms?

Work on your site and content so that Google finds your pages, understands what they're about and shows them to people looking for what you offer. The result is free (organic) traffic from search.

How long does SEO take to work?

Google says some changes show up within hours and others take months. Technical fixes work fastest, while new content and authority build up over months. A new site in a competitive niche rarely reaches page one straight away.

Can I do SEO myself?

The basics, yes. Google Search Console, a Google Business Profile, unique page titles and a separate page for each service don't need a specialist. You'll want help with technical problems, a larger site or online store, or a very competitive niche.

What's the difference between SEO and Google Ads?

With Google Ads you pay for every click, and the visitors stop when the ads do. SEO takes longer, but people keep arriving without an ad budget. Many businesses use both: ads for quick results, SEO for the long run.

Can anyone guarantee a number one ranking on Google?

No. Google says explicitly that no one can guarantee a number one ranking. If someone promises guaranteed rankings, find someone else.
