What Is SEO? The Fundamentals of Search Engine Optimization

SEO (Search Engine Optimization) is the set of practices that make it easier for search engines to find your website, understand it correctly and show it to people for relevant searches. The short answer: SEO is not a trick or a one-time setting. It means building a site that is technically sound, genuinely answers the user's question and earns trust, and then keeping it that way.

What is SEO and why does it matter?

When customers look for a product or service, the first thing they usually do is type it into a search engine: "concrete cutting company," "corporate identity design," "water treatment service" and so on. A site that doesn't appear for these searches can't reach the people looking for it, however well designed it is.

The goal of SEO is not to "trick Google" but to serve two parties at once:

• The search engine: so it can crawl your pages without trouble, understand your content correctly and work out which searches it is relevant for.
• The user: so they can find the answer they are looking for quickly, clearly and reliably.

In Google's own words, the aim of its search systems is to surface helpful, reliable content created for people. That is why good SEO and a good website are largely the same thing.

It is also important to separate SEO from paid advertising. With search ads you pay per click, and when the payments stop, so does the visibility. The "organic" visibility you earn through SEO cannot be bought. Google states clearly that it does not accept payment to crawl a site more often or to rank it higher.

How do search engines work? Crawling, indexing and ranking

The easiest way to understand SEO is to know how Google processes a page. According to Google Search Central, the process has three stages.

1. Crawling

Google explores the web with automated programs called Googlebot. It discovers new pages through links on other pages, through sitemaps and through addresses it already knows. It downloads the page and, when needed, runs the JavaScript to "render" it the way a browser would.

The reasons a site gets stuck at this stage are usually technical: sections blocked by mistake in the robots.txt file, pages that won't open without logging in, or a server that often returns errors or responds very slowly. We explained why the server side matters in our post on hosting.

2. Indexing

The crawled page's text, title tag, image alternative text (alt) and other content are analyzed. The result is stored in a huge database called Google's index. At this stage Google groups pages that are copies of each other or very similar, and picks one of them as the "canonical" version.

An important detail: indexing is not guaranteed. Low-quality content, tags that block indexing such as noindex, or a site structure that is hard to process can keep a page out of the index.

3. Serving results (ranking)

When a user searches, Google finds the matching pages in its index and ranks them by relevance and quality. Hundreds of factors play a role in this ranking. The user's location, language and device also change the results. A search for "water treatment service" can return different results in Istanbul and in Izmir.

Knowing these three stages makes it easier to locate a problem. If your site doesn't appear at all, the problem is most likely in crawling or indexing. If it appears but ranks low, the problem is more likely content and trust.

The three pillars of SEO: technical, content and authority

Grouping SEO work under three headings makes it easier to see what is missing.

Technical SEO

Technical SEO makes sure your content can "reach" the search engine. The most basic items are:

• HTTPS: The site loads over a secure connection. We covered the difference between HTTP and HTTPS and SSL certificates in separate posts.
• Mobile-friendliness: In October 2023, Google announced that the move to mobile-first indexing was complete. In other words, Google crawls your site primarily as a smartphone would. Content that is missing or broken on mobile counts as missing in search too.
• Speed and page experience: Google says it uses a set of measurements it calls Core Web Vitals in its ranking systems. Since March 2024, these measure loading speed (LCP), responsiveness to interaction (INP) and visual stability (CLS). Even so, Google says it tries to show the most relevant content even when page experience is weak. Speed doesn't replace good content, but it can make a difference between similar pages.
• Sitemap and robots.txt: A sitemap tells Google which pages are important. robots.txt defines which addresses crawlers may access. Note: robots.txt is not a way to hide a page from Google. For that you need noindex or password protection.
• Duplicate content: When the same content opens at more than one address (for example, with and without www), crawling is wasted. A single address is chosen with redirects and the canonical tag.

Content

Content is your answer to the user's question. The recommendations in Google's SEO Starter Guide are quite concrete:

• Write a unique title for every page. The title should be short, clear and describe the page accurately. The blue link shown in search results largely comes from here.
• Write a page-specific meta description. Google often picks the description in search results from the page content itself and uses the meta description only occasionally. Still, a well-written description can influence the decision to click.
• Use readable URLs. An address like /services/concrete-cutting/ is more descriptive than /?p=123.
• Write descriptive link text. Instead of "click here," use a phrase that describes the page the link leads to.
• Add alternative text (alt) to images. Briefly describe how the image relates to the page. This helps both visually impaired users and search engines.

The real question for content is this: would someone find this page useful even if search engines didn't exist? Google treats content made mainly to attract search traffic, content that jumps from topic to topic, and content whose date is changed just to "look fresh" as warning signs.

Authority and trust

A search engine also tries to understand how far it can trust a piece of content. The concept you will often hear here is E-E-A-T: experience, expertise, authoritativeness and trustworthiness. Google states that it is not a ranking factor on its own, but that its systems try to recognize content with these qualities. Of the four, trust is the most important.

For a business website, trust in practice comes from:

• A real company name, address and contact details.
• Reference and project pages that show your work.
• Clarity about who wrote the content (author name and a short bio).
• Links from other sites that give them because they genuinely find you useful.

Buying links or mass-submitting to meaningless directories does not create that trust. Google's spam policies explicitly prohibit such link schemes.

What to watch out for in SEO: common myths

A lot of misinformation about SEO has piled up over the years. According to Google's own guide, you don't need to spend time on these:

• The meta keywords tag: Google Search doesn't use it.
• Repeating the keyword over and over: Google's spam policies call this "keyword stuffing," and it does harm.
• Keywords in the domain name: Having a keyword in your domain name or URL has very little effect on ranking. Choose your domain for your brand. We also covered choosing a domain name.
• A word count target: According to Google, content length alone doesn't affect ranking, and there is no "ideal word count." Write as much as the topic needs.
• A guaranteed number one spot: Google says "no one can guarantee a #1 ranking on Google" and advises caution with agencies that promise it.

What changed in March 2024?

On 5 March 2024, Google announced both a core update and three new spam policies. The update made the systems that assess whether content is "helpful" part of its core ranking systems. The new spam policies were:

• Scaled content abuse: Producing large numbers of pages purely to gain rankings without helping users. It doesn't matter whether the content is produced by automation or by people.
• Site reputation abuse: Publishing third-party content without the site owner's oversight in order to benefit from a trusted site's reputation.
• Expired domain abuse: Buying an old domain to use its past reputation to rank low-value content.

The message for businesses is simple: rather than quickly producing many pages, preparing fewer pages that are genuinely useful is a safer and more lasting approach.

How long does SEO take to show results?

This is the most common question, and the honest answer is "it depends." According to Google's starter guide, some changes may take effect within a few hours and others within several months. Google recommends waiting at least a few weeks before judging the effect of a change.

The main factors that affect the timeline:

• Whether the site is new or has been live for years.
• The competition for the target searches.
• How deep the technical problems (crawling, indexing) go.
• How regularly content is produced and updated.

That is why we recommend being cautious about fixed-deadline promises such as "page one in a month." Think of SEO as maintenance and growth, not as a campaign.

Where should you start with SEO on your own site?

A few steps that need no technical knowledge will show you where you stand:

1. Are you in the index? Search Google for site:yourdomain.com. If results appear, your site is indexed. If there are no results at all, a technical check comes first.
2. Set up Google Search Console. It is Google's free tool. It shows which searches you appear for, which pages are indexed and any technical errors. You also submit your sitemap there.
3. Review your page titles. Does every page have its own title that describes what it offers?
4. Create a separate page for each service. Describing each service on its own page, rather than listing everything on one page, makes things easier for both users and search engines.
5. Use your own site on mobile. Browse it on your phone like a customer: Does the menu work? Does tapping the phone number start a call? Does the form submit?
6. Complete your contact and trust information. Keep your address, phone number, references and "about us" page up to date.

If your site is still being built, treat SEO as part of the planning, not as a layer to add later. We also discussed this in our post on what to check before commissioning a corporate website. Good user experience (UX) also supports SEO indirectly: visitors who easily find what they are looking for stay on the site and convert.

Our experience

In our web projects, we treat SEO as part of the site architecture, not as a "package" added after launch. We first work out which searches the business needs to be found for, then build the page structure around them.

We followed this approach on the site we built for Tuğra Karot: instead of putting all their core drilling and concrete cutting services on a single page, we set up a service-based, SEO-friendly page structure. On each page, we placed phone and WhatsApp actions so visitors can act as soon as they find the service they need. For Bağçepark, we also structured the product catalog and the on-site survey request as separate, clear sections.

We build the vast majority of our projects on WordPress. This lets the business update its own content easily after launch. That matters for SEO, because a regularly updated site stays healthier in the long run.

Conclusion

SEO means making your site open, clear and trustworthy for both search engines and people. The technical foundations should be solid, the content should genuinely answer the question and your site should earn trust. Shortcuts may work today but can become a risk tomorrow. Patient work based on Google's own guidelines delivers lasting results.
