SEO

What is SEO and how does it work?

SEO (search engine optimisation) means improving your website so that search engines can easily find it, understand it and rank it higher in the free (organic) search results for the queries your customers use to look for your services or products. You don't pay Google for clicks, but results take time: usually 3–6 months.

What is SEO in plain English?

SEO is the work that prepares a website for both search engines and people: so that Google can reach every important page, understand what each one is about and consider it a good answer to a customer's question. In full it's called search engine optimisation; in Lithuanian, people usually search for it as ‘SEO optimizavimas’.

SEO differs from advertising in that you pay the search engine nothing for impressions or clicks. You pay for the work: technical fixes, content, mentions on other websites. Results take a few months, but a position you've earned in the organic results doesn't vanish the day your budget runs out, as happens with ads.

How does Google find and rank pages?

Google processes pages in three stages: its crawler, Googlebot, crawls them; the system analyses them and adds them to the index; and when it receives a query, it selects and ranks the most relevant pages from the index. The job of SEO is to remove the obstacles at each of these stages.

How a search engine works: crawling, indexing, ranking and the obstacles at each stage
The three stages and the most common obstacles – more in the list below.
  1. Crawling. The crawler learns about a new page from links and the sitemap (sitemap.xml). If a page is blocked in the robots.txt file, no link points to it or the server responds with an error, the crawler may never reach it.
  2. Indexing. Google analyses the text, headings and images and decides whether to keep the page in the index. Pages marked ‘noindex’ don't get in, and duplicates and very short pages with little information often don't either.
  3. Ranking. For each query, pages are chosen according to how well they match the searcher's intent, how useful their content is and whether they're easy to read on a phone. Language, location and other signals also play a part.

In Lithuania, Google has no serious competitors: according to StatCounter, in August 2026 it accounted for 91.75% of searches, Yandex for 3.98% and Bing for 3.21%. Still, Bing shouldn't be forgotten: Microsoft Copilot relies on its index, and ChatGPT search also uses external search sources. So it's worth verifying your website in Bing Webmaster Tools as well.

What's the difference between technical, on-page and off-page SEO?

Technical SEO makes sure the website is accessible to crawlers, fast and secure; on-page SEO makes sure every page clearly answers a specific question; and off-page SEO makes sure other sources recommend your website. These parts only work together: even strong links won't help a page that Google can't index.

Technical, on-page and off-page SEO: what is done, examples and who does it
The three parts of SEO – more detail in the table below.
PartWhat is doneExamplesWho usually does it

Off-page SEOreputation beyond your websitebacklinks, mentions in the media and industry portals, Google Business Profile, customer reviewsan SEO specialist together with the company

For companies serving customers in a particular city, local SEO adds to these: Google Business Profile, your address, service area and reviews. It's especially important for searches like ‘…in Vilnius’ or ‘…near me’.

Which links help, and which do harm?

A backlink is a link from another website to yours. Google may treat it as a recommendation if it appeared naturally: someone added it because your page is useful to their readers. The most valuable sources:

  • websites of partners, suppliers and customers that mention your company because of genuine collaboration;
  • articles in the media and industry portals, e.g. a comment from your specialist or a review of your field;
  • lists of association members, exhibitors and event participants;
  • Google Business Profile and a few reliable, genuinely visited business directories with consistent company details.

Google's spam policies treat the following as link manipulation: buying and selling links to influence rankings, excessive link exchanges (‘link to me and I'll link to you’), automatically generated links and links in low-quality directories. So-called PBNs (private blog networks) – networks of websites created purely to host links – usually fall into the same category. Such links can cost your website its rankings; at best, Google simply ignores them and the money is wasted. A paid publication doesn't break the rules if the link in it carries the rel="sponsored" or rel="nofollow" attribute.

How long does SEO take to deliver results?

The first changes in rankings and visitor numbers are usually seen after 3–6 months, and in highly competitive fields and for brand-new websites after 6–12 months. That's the typical timeframe in our experience, not a promise: the exact timing depends on your competitors, the state of your website and how often Google crawls it.

  • Starting point. If important pages aren't being indexed, fixing that can bring a quick change. If everything is technically sound, growth is slower – through content and mentions.
  • Competition. The queries ‘plumber in Panevėžys’ and ‘consumer credit’ call for completely different levels of effort.
  • Age and reputation of the website. A new domain has to earn trust from scratch.
  • Pace of work. One new article every six months and several articles every month produce very different results.

Progress is worth measuring by more than just rankings. Google Search Console shows impressions, clicks and the queries people find you by, while Google Analytics 4 shows what visitors from search do on your website: call, fill in a form or buy.

What does AI search change for SEO?

AI search doesn't make SEO obsolete, but it changes how people get their answers. Google's AI Overviews and AI Mode, ChatGPT, Perplexity and Copilot build an answer from several sources and add links to them. Google states that there are no additional requirements for AI Overviews: a page must be indexed and eligible to be shown in search with a snippet.

In practice this means two things. First, technical and on-page SEO become even more important, because a page that isn't indexed will be seen by neither search nor AI. Second, some people get their answer right on the search results page, so it's worth writing text that can be quoted: a direct answer in the first sentence, figures, tables, an update date. We explain how to do this step by step in our article ‘How to get into ChatGPT and Google AI answers’, and we do it on an ongoing basis through our AI search optimisation (GEO) service.

Which SEO tips are now out of date?

Some SEO tips still repeated online worked a decade ago – or never worked at all. If an SEO proposal lists them as the main tasks, it's worth asking what exactly you're paying for.

Outdated tipWhat's actually true
Fill in the ‘meta keywords’ tagGoogle announced publicly back in 2009 that it doesn't use this tag for ranking
Repeat the keyword as often as possiblekeyword stuffing is listed as a violation in Google's spam policies; text should answer the question in natural language
Put every keyword in boldbold highlights the key point for the reader; words bolded artificially just get in the way of reading
Register your website in hundreds of directorieslow-quality directories count as link manipulation; it only makes sense to register in a few reliable, genuinely visited directories
Create a separate page for every keyword variantone need – one comprehensive page; near-identical pages compete with each other
Choose whoever guarantees the number one spot in Google searchGoogle says nobody can guarantee the top spot and advises avoiding SEO providers who make such promises

Can you do SEO yourself?

Yes, a company can do a good deal of the basic work itself, especially if the website is small and competition is moderate. You'll need a specialist when the website's code has to be changed, hundreds of pages need fixing or you need to work out why visitor numbers suddenly dropped.

  • Connect your website to Google Search Console and Bing Webmaster Tools and submit your sitemap.
  • List 10–20 questions customers ask before buying, and check whether your website has pages that answer them.
  • Write a unique title and meta description for every important page.
  • Complete your Google Business Profile and ask customers for reviews.
  • Every month, review the Page indexing report in Search Console: are your important pages getting into the index?

We describe the full check step by step – with free tools and priorities – in our article ‘How to check your website's SEO yourself: a 30-point checklist’.

Frequently asked questions

How is SEO different from Google Ads?

Google Ads appear shortly after a campaign goes live, but you pay for every click, and when you pause the campaign or the budget runs out, they disappear. SEO results take a few months, but you don't pay for clicks and your rankings don't vanish overnight. The two are often combined: ads bring in enquiries now, while SEO gradually reduces your dependence on the advertising budget.

Do you have to pay Google for SEO?

No. Google doesn't charge for inclusion or position in its organic search results – this is also stated in Google's official documentation. You only pay for the work: your own employee, a freelancer or an agency. Paid positions marked with a ‘Sponsored’ label are Google Ads advertising.

How much do SEO services cost?

Saitai.lt monthly SEO plans cost €199/month (Start), €349/month (Business, with AI search optimisation (GEO)) and from €649/month (Premium), with a minimum contract term of 3 months. A one-off SEO audit costs from €49 for a small website and from €99 for an online store or catalogue. Prices include all taxes – no VAT is added.

Where should you start with SEO for a new website?

With the structure, even before launch: a separate page for every important service or product group, unique titles and descriptions, readable URLs. If the new website replaces an old one, the old URLs must be linked to the new ones with 301 redirects, or you'll lose some of your visitors from search. Once the website is live, connect it to Google Search Console and submit the sitemap.

What should you do if an SEO company promises the number one spot in Google?

Ask exactly how they'll achieve it. Rankings are determined by Google's algorithms, not by an agency, so nobody can guarantee the top spot – Google even advises steering clear of providers who make such promises. A credible proposal describes specific work: how many articles a month, which technical fixes, and what data you'll see in the report.
