Domain name SEO is an important topic for every website owner. Your domain name and SEO are closely connected. The choice of your domain name, extension and technical configuration can have a measurable effect on your position in Google. But how exactly does your domain affect your ranking? In this article you will discover all the ways your domain name influences your SEO performance, and you will learn how to set up an SEO-friendly domain strategy.

Domain name SEO and keywords: does a keyword in your domain still help?

For years it was a popular SEO strategy to work your most important keyword into your domain name. Exact Match Domains (EMDs) such as cheap-flights.nl or dog-insurance.com often ranked high in Google, purely based on their domain name. But how do domain name SEO and keywords stack up in 2026?

In 2012 Google rolled out the EMD algorithm, which sharply reduced the preference for exact match domains. Since then, EMDs no longer rank high automatically. Even so, a keyword in your domain has not become worthless. It offers a small advantage because the domain name is highlighted in search results when it matches the query, and it makes it instantly clear to users what to expect.

The risk of an EMD is that it limits your brand. If you register cheap-shoes.nl and later also want to sell bags, you are stuck with a name that is too specific. A brand name such as coolblue.nl or bol.com offers more flexibility. Our recommendation: pick a domain name that reflects your brand, not one built purely around keywords.

Domain name SEO: domain age and domain authority

Domain age is a factor that comes up regularly in SEO discussions. Google has confirmed that domain age in itself is not a direct ranking factor. However, older domains have usually built up more backlinks, a longer history of content and more trust with Google. That translates indirectly into better rankings.

Domain authority (a metric devised by Moz, not by Google) gives an indication of how strong a domain is in the eyes of search engines. High domain authority comes from quality backlinks, consistent content publishing and a solid technical foundation. A new domain starts with low authority, but can build it up by consistently publishing valuable content and earning relevant links.

In practice this means: do not worry if you have a new domain. Focus on producing excellent content, earning quality backlinks and a technically healthy website. The authority will follow. A new domain with great content regularly beats an old domain with mediocre content in the search results.

.nl versus .com: which extension is better for domain name SEO?

A common question about domain name SEO performance is whether you are better off with a .nl or .com extension when you target the Dutch market. The answer is more nuanced than you might expect.

Google uses the ccTLD (.nl, .be, .de) as a geotargeting signal. A .nl domain is automatically associated with the Netherlands, which can help you rank in Dutch search results. A .com domain is generic and is not automatically tied to a country, but you can set a country target through Google Search Console.

In practice, the choice between .nl and .com makes little difference for Dutch SEO, as long as the rest of your website is well optimized. Both extensions can rank excellently in Google.nl. The choice depends more on your audience: if you focus purely on the Netherlands, then .nl is logical and recognizable. If you also want to score internationally, .com offers more flexibility. The best approach is to check both domains for availability and make the right choice for your situation.

Subdomain versus subfolder: the SEO impact

An important technical choice that affects your domain name SEO is whether you use subdomains or subfolders for different sections of your website. Think of blog.yoursite.nl (subdomain) versus yoursite.nl/blog/ (subfolder).

Google has stated that it treats subdomains and subfolders equally in principle. In practice, however, SEO experts often see better results with subfolders. The reason is that all content sits on the same domain, so the domain authority stays bundled together. With a subdomain you essentially have to build authority all over again for that subdomain.

Our recommendation for most websites: use subfolders. Put your blog on yoursite.nl/blog/ instead of blog.yoursite.nl, and your store on yoursite.nl/shop/ instead of shop.yoursite.nl. Only use subdomains when there is a technical need, for example when the subdomain runs on a different server with a completely different technical stack.

Domain name SEO boost: HTTPS and SSL as a ranking factor

Since 2014, HTTPS has been a confirmed ranking factor in Google. Websites with an SSL certificate get a small but measurable advantage in the search results over HTTP websites. In 2026, HTTPS is no longer optional but an absolute requirement. Google Chrome flags HTTP websites as "Not secure", which scares off visitors and raises your bounce rate.

The good news: an SSL certificate does not have to cost anything. Free SSL certificates through Let's Encrypt offer the same encryption as paid alternatives and are trusted by all browsers. With Theory7 web hosting, SSL is included as standard and configured automatically.

When switching from HTTP to HTTPS, make sure you correctly set up 301 redirects from all HTTP URLs to their HTTPS versions. Also update all internal links, sitemaps and canonical tags to HTTPS. An incorrect migration can temporarily hurt your SEO.

Redirect chains and their impact on SEO

Redirect chains occur when a URL is forwarded through several intermediate steps to its final destination. For example: page-a.html redirects to page-b.html, which redirects again to page-c.html. Every extra step in the chain leads to a loss of link value (PageRank) and slows down load time for search engines and visitors.

Google can follow up to 5 redirects in a chain, but that does not mean it is desirable. Keep your redirects as short as possible: every URL should forward directly to the final destination. Regularly check your website for redirect chains with tools such as Screaming Frog or Ahrefs Site Audit. This is an often overlooked aspect of domain name SEO that can make a significant difference.

A common cause of redirect chains is moving or restructuring a website several times without cleaning up the old redirects. After every migration or URL change, it is wise to review your redirect configuration and remove unnecessary chains.

Multiple domains and SEO: canonicals and redirects

Many companies own several domain names: the .nl and .com version, typo variants or old domain names from before a rebrand. What is the best way to handle this from an SEO point of view?

The golden rule: choose one primary domain and forward all other domains to it with a 301 redirect. A 301 redirect tells Google that the alternative domain has permanently moved to the primary domain, so the link value is passed on.

What you absolutely must avoid is publishing the same content on multiple domains. This leads to duplicate content, forcing Google to choose which version to show, and your link value gets spread across multiple domains. Even with canonical tags this is a suboptimal strategy. Always use 301 redirects and concentrate all your SEO effort on one domain.

For international websites with several language versions on different domains (such as yoursite.nl for the Netherlands and yoursite.de for Germany) the situation is different. Here you use hreflang tags to tell Google which version is meant for which country and which language. This prevents duplicate content problems between the language versions.

Improving domain name SEO: building domain authority

Domain authority is not a direct Google ranking factor, but the concept behind it (the strength and trustworthiness of your domain) is certainly important for your domain name SEO. Here are the key steps to build up the authority of your domain.

First: consistently publish quality content that offers value to your audience. Content that solves problems, answers questions or provides unique insights attracts links on its own. Second: work on earning backlinks from relevant, respected websites in your industry. A link from a reputable news site or trade association is worth more than dozens of links from obscure directories.

Third: make sure your website is technically flawless. Fast load times, mobile-friendly design, correct use of structured data and a clean site structure help search engines understand and index your content better. Fourth: be patient. You do not build domain authority in a month. It is a long-term investment that requires consistency. Read more about SEO tips for beginners to get started right away.

Domain migration and SEO impact: setting up 301 redirects correctly

Moving your website to a new domain is one of the riskiest operations for your SEO. A poor migration can lead to a significant drop in organic traffic that can take months to recover from. But with the right approach, you can minimize the impact.

The key is setting up 301 redirects correctly from every page on the old domain to the corresponding page on the new domain. Not a generic redirect from all pages to the homepage, but page-by-page redirects. On top of that, you should keep the old domain active (with the redirects) for at least 6 to 12 months, submit your new domain in Google Search Console, and update all sitemaps, canonical tags and internal links.

Expect a temporary drop in rankings and traffic, even with a perfect migration. Google needs time to process the changes and transfer trust to the new domain. Traffic typically recovers within 2 to 6 months after a correct move, but this can take longer for large websites.

Buying expired domains for SEO: does it still work?

Buying expired domains with existing backlinks is a well-known SEO tactic. The idea is that you take over the built-up authority and backlinks of the expired domain. But does this strategy still work in 2026?

Google is smart enough to recognize when an expired domain is reused for a completely different purpose. If you buy an old veterinary clinic domain and turn it into an online casino, Google will likely ignore or devalue the existing backlinks. But if you use the domain for a related topic and publish quality content, the existing authority can indeed offer an advantage.

If you are considering buying an expired domain for SEO, always check the backlink profile (are the links from quality sites?), the domain history through the Wayback Machine (has the domain not been used for spam?), and whether the domain is not on a blacklist. A domain with a bad history can harm your SEO rather than help it.

New domain extensions and SEO

New domain extensions such as .amsterdam, .shop, .online and .tech are becoming more popular. But how do these extensions affect your domain name SEO? Google has confirmed several times that all domain extensions are treated equally in the search results. So a .shop domain has no advantage or disadvantage compared to a .com or .nl domain.

Still, there are indirect effects to keep in mind. Users are more familiar with .nl and .com, so they are more likely to click on these extensions in the search results. A higher click-through rate (CTR) is positive for your SEO. In addition, some new extensions are associated with spam (particularly .xyz and .online), which can reduce trust with visitors.

Our recommendation: choose .nl for the Dutch market and .com for international. New extensions such as .shop or .amsterdam can be a fun addition for specific projects, but do not use them as your primary domain unless you have a good reason.

Tips for better domain name SEO

Frequently asked questions about domain name SEO

Does my domain name affect my Google ranking?

Yes, but indirectly. Your domain name itself is not a strong ranking factor, but related aspects such as HTTPS, domain authority, load speed and the choice between subdomain and subfolder do have a measurable effect on your position in Google.

Is a .nl or .com domain better for SEO in the Netherlands?

Both extensions can rank excellently in Google.nl. A .nl domain gives Google a geotargeting signal for the Netherlands. A .com domain is neutral but can be targeted at the Netherlands through Search Console. For purely Dutch websites, .nl is the logical choice.

Should I put a keyword in my domain name?

It is no longer necessary. Google attaches less value to exact match domains than it used to. A strong brand name that is memorable and inspires trust is often more effective than a keyword domain. Focus on content and backlinks for your SEO instead.

How does a domain migration affect my SEO?

A domain migration can temporarily hurt your rankings. With correct 301 redirects, updated sitemaps and patience, traffic usually recovers within 2 to 6 months. Plan a migration carefully and follow the step-by-step plan in this article.

Are new extensions (.shop, .online) bad for SEO?

No, Google treats all extensions equally. The difference is in user perception: .nl and .com are more recognizable and get clicked more often in search results. For specific projects, new extensions can work perfectly well.

Domain name SEO: future developments

The influence of your domain name on SEO is constantly changing. It is important to stay up to date with the latest developments and trends.

New domain extensions and SEO

Google treats new extensions such as .shop, .blog and .tech the same as traditional extensions like .com and .nl. Even so, a niche extension can offer benefits by making it immediately clear what your website is about. A .shop extension for an online store or .tech for a tech company can raise the click-through rate, which indirectly improves your SEO. Choose an extension that fits your audience and brand identity.

Domain age and authority

An older domain has often built up more authority than a new domain. This is not directly because of the age itself, but because older domains have had more time to build backlinks and trust. If you buy an existing domain, check the backlink profile and the history. A domain with a spam past can actually be harmful to your SEO. Use the Wayback Machine to research the history of a domain before you buy it.
