What Is International SEO?

If you’re a brand that’s expanding internationally and you need to get more targeted traffic and visitors at low costs for each new country, you need to work with one of the best international SEO agencies. They will create an SEO campaign for each country, hire marketers to handle the work and manage them individually.

  • Global SEO, used interchangeably with international SEO, focuses specifically on optimizing a website for different geographical locations, languages and cultural nuances.
  • General SEO, on the other hand, optimizes a website to rank well in different search engines’ results, without necessarily focusing on specific locations or languages.

Let’s say you’re a multinational e-commerce business that operates in the USA, Germany and Japan, and you hire a global SEO company. Their goal would be to make sure that your website is visible and ranks high in search results for each of these markets.

For instance, Amazon has country-specific domains for all its international locations:


In contrast, if you needed general SEO services for your local business (a business that operates in a single language and country), your focus would be much different.

You would still care about website structure, content and link building, but you wouldn’t need to worry about localizing for different languages or using hreflang tags. Your strategy would instead be centered around understanding the competitive landscape, optimizing for relevant keywords, improving website speed and usability, and earning quality backlinks.

This involves several international SEO strategies, such as:

  • Website Structure: You may need to create separate subdomains or subdirectories for each geographical area. For instance, for the German market, the URL might be “” or ““. This makes it clear to both users and search engines that this version of your website is specifically for German speakers. And depending on your international footprint, the global SEO services provided might involve using country code top-level domains (ccTLDs), subdomains or subdirectories.
  • Language and Localization: The global SEO company would localize your website’s content to match the language and cultural nuances of each target market. This isn’t about a simple translation but adapting the content to align with local expressions, units of measurement, and date formats.
  • Keyword Research: Just like with local SEO, keyword research is a critical part of global SEO services. The company would carry out this research for every target market to discover the terms your international audience is using in their searches:
  • Hreflang Tags: These HTML tags indicate to search engines what language and geographical area a webpage is intended for. For example, for a webpage intended for English speakers in the USA, the hreflang tag would be “en-us”, and for German speakers in Germany, the hreflang tag would be:
  • Local Link Building: An essential part of their global SEO services would be to devise a link-building strategy that focuses on securing high-quality backlinks from reputable websites within each target country.
  • International SEO Audit: Regular SEO audits are crucial to identify and remedy any issues such as broken links, slow page speed, or duplicate content. The company would also monitor your SEO performance to tweak the strategy as necessary.
  • Local Search Optimization: If you have physical locations in different countries, they would also optimize your website for local searches. This might involve creating and optimizing Google My Business listings for each location, gathering local reviews and conducting competitor research in country-specific search engines (and not just, since different sites rank higher depending on the target location and language):

  • Compliance: Each country has its own set of laws and regulations regarding digital content and privacy. The international SEO services would ensure your website adheres to these laws, such as Europe’s GDPR.

The specific strategies and services an agency offers would depend on their expertise and your unique needs and goals. Before engaging with a global SEO company, it’s vital to discuss your objectives and ensure they can provide the international SEO services necessary to meet them.

Why Hire an International SEO Agency? Top 3 Reasons

Although it’s reasonable to think that any ol’ SEO agency can help you expand your business around the world, the key to a successful SEO campaign that reaches an audience outside of your local or national demographic is international SEO.

Let’s take a look at the top three reasons to hire an international SEO agency.

1) Adherence to International SEO Best Practices

International SEO focuses on optimizing a website so that the search engines recognize the countries and languages in which you want to rank your site.

The differences between traditional SEO and its international counterpart are minor but crucial. An SEO practitioner who’s not trained or experienced in executing global SEO campaigns will have a hard time ranking a website for multiple countries and languages.

In contrast, international SEO agencies take an integrated approach that follows all the best practices to rank a website for any country and language, such as:

  • Using the hreflang tag properly: Google uses this tag to understand which language and country-specific version of it should a page rank for. Hreflang tags also prevent a duplicate content issue because you explicitly indicate that there are alternative pages on your domain.
  • Choosing a correct URL structure: This includes deciding whether to use a country or language-specific domain, subdomain, subdirectory, or dynamic parameter (as seen in the image below):
  • Building links on local websites: Getting links from sites located in the country a website wants to rank for can make a difference.

2) Customization of Marketing Strategy for Each Global Audience

Two challenges you’ll face when trying to sell your products or service in a different country are:

  • Acquiring traffic from different countries
  • Providing content to visitors in their regional language

Translation is essential here because of language and cultural differences. Even the small but noticeable differences between languages like American and British English can break a marketing campaign without proper translation.

Mr. Beast, a renowned YouTuber, embraced international expansion by dubbing his videos in different languages and creating multiple international YouTube channels:


This approach allows him to tap into diverse markets, which resulted in exponential growth.

Note: I don’t recommend machine translations for different languages because auto-translations are not always accurate, and if you don’t speak that language, you won’t catch the errors. Inaccurate translations hamper the user’s experience (and may make your site look like fraudulent), as well as cause duplicate content issues. Always get a native speaker to translate your content into the targeted country’s regional language.

This is why hiring an international SEO agency is an excellent idea: They will have an expert network of local linguists to rewrite their client’s content for each market they operate in.

3) Expertise in the Latest Global SEO Trends and Tactics

Any SEO agency — global or locally focused — must stay informed with the latest SEO trends. Since international agencies are large enough to have offices around the world and hire the best local talent, hiring one almost guarantees they will execute the latest, most effective SEO tactics.

Some of the global search engine optimization strategies that can effectively improve the presence of a website internationally are international keyword research, multilingual content marketing and content optimization, global link building and hreflang tag implementation.

How to Choose the Best Global SEO Agency for Your Business

It’s like selecting any search engine optimization company, except you’ll be looking for international SEO services. When choosing a global firm, here are three important things to look for.

A Strong International Network of Account Managers

First and foremost, a global SEO agency must have people working in or experienced with the country your business operates in. Ideally, that should include having offices in your target market or countries, although having qualified employees who target those markets works almost as well.

For example, if your social media marketing company is located in France and wants to target North America, hire an agency with offices in both regions.

Also, if your business is in expansion mode, make sure the agency is located or experienced in the markets your company will expand to. So be sure to discuss this point thoroughly before hiring an agency.

Deep Industry Expertise and SEO Knowledge

Any search engine optimization expert can audit a website, optimize its tags and research keywords regardless of their clients’ country. However, uncovering intent, defining a keyword plan, and knowing which outlets are ideal to pitch for links requires a lot of experience in a given industry.

Hire an SEO agency that has proven technical excellence and key international SEO services in your specific industry, including:

  • International keyword research
  • Competitor analysis
  • Multilingual content marketing
  • User experience optimization
  • Multilingual content optimization
  • Global link building
  • Site speed optimization
  • Hreflang tag implementation
  • Site architecture optimization
  • Technical SEO implementation

Clear and Effective Global SEO Strategy

There are countless horror stories of companies that hire SEO firms that use a lot of jargon to sell their services and end up underperforming — or, worse yet, they end up with a penalty.

Before you hire a global SEO agency, make sure they can explain their SEO strategies clearly — and that includes the implementation of best practices for international SEO.

Here are four questions you should ask that will help you understand their strategy:

  • Can you explain your SEO approach in under 60 seconds? If they can’t explain their process succinctly, beware.
  • What’s your favorite URL structure for international SEO? Take notes and think about the cost-benefit relationship of their suggestions.
  • How do you acquire links? Anything content or outreach-related is good; anything purchased is a big no-no.
  • How do you measure results? If they say organic traffic increases, sales, and leads (among other metrics), great. If their answers include words like “rankings” and “brand awareness,” think twice about hiring them.

Summary: Key Points for Hiring the Right Global SEO Agency

Let’s face it: Hiring a single agency capable of handling SEO campaigns in multiple geographic regions can be tough. In today’s, digital marketing world, it’s best to start small, get an initial set of results that motivate your team, and scale from there.

We want to close this article with a quick summary of how to hire a global SEO agency:

  • Decide what countries your business is expanding to.
  • Make a list of all of the languages these countries speak—that includes country-specific variations of the same language, such as American and British English.
  • If your aggregate list of countries and languages is less than three, you may want to follow our guide on international SEO and see if you can do it yourself.
  • If your team can’t handle this work or if your list of targeted countries and languages is greater than three, pick one of the five agencies we mentioned in this article.

Remember that SEO is a channel that takes time to work. The earlier you start working on your global SEO strategy, the better it will be for your business’ growth.

Global SEO FAQs

  • Who is the best SEO company in the world?

    Determining the “best” SEO company in the world can be subjective and depends on various factors such as your specific needs, budget, and the markets you are targeting.

  • What is global SEO?

    Global SEO, or international SEO, is the practice of optimizing your website for search engines to improve its visibility in multiple countries and languages. Unlike local or national SEO, which focuses on reaching audiences in a specific location or country, global SEO aims to capture and engage audiences across international markets.

    This specialized form of SEO involves a range of strategies and techniques designed to make your website more accessible and relevant to people around the world. In addition to basic global search engine optimization practices mentioned above, additional strategies include:

    • Language and Localization: One of the first steps in global SEO is to localize the content, meaning adapting it to the local language and culture of the target market. This goes beyond simple translation and may include modifying images, currency, and cultural references.
    • Geo-Targeting: This involves setting up your website structure so that search engines can easily identify the countries or languages you are targeting. This can be done through country-specific domain names, subdomains, or subdirectories.
    • Cultural Sensitivity: Understanding cultural nuances and preferences is essential when targeting international markets. What works in one country may not necessarily work in another.
    • Legal and Regulatory Compliance: Different countries have different laws and regulations concerning online content and commerce. Being aware of these is crucial when implementing international SEO services.
  • What does an SEO agency do?

    An SEO agency specializes in optimizing websites to improve their visibility in search engine results, with the ultimate goal of increasing website traffic, conversions and revenue. These agencies offer a range of SEO services that encompass various aspects of search engine optimization.

    Here’s a quick breakdown of some of the key services that an SEO agency typically provides:

    • Keyword Research and Strategy: An SEO agency identifies the keywords and phrases that are most relevant to your business and target audience.
    • On-Page Optimization: This involves optimizing the individual pages of your website, including the content, meta descriptions, title tags, and HTML structure, to make them more search engine friendly.
    • Off-Page Optimization: Off-page SEO focuses on activities that occur away from your website but still affect its ranking, like link building.
    • Technical SEO: Technical SEO involves optimizing the backend of your website — like site architecture and optimizing robots.txt files — to improve its performance, speed, and crawlability for search engines.
    • SEO Audit: This is a comprehensive review of your website’s current SEO status, identifying strengths, weaknesses, and areas for improvement.
    • Content Marketing: SEO agencies often provide content creation and marketing services, crafting high-quality, SEO-friendly content that engages your audience and improves your site’s search engine ranking.
    • Local and International SEO: While some agencies specialize in local SEO to target customers in a specific geographic location, others offer international SEO services to help your business reach a global audience.
  • How much does international SEO cost?

    The cost of international SEO can vary widely depending on several factors, including the scope of your project, the complexity of your website, and the global SEO company you choose to work with. Unlike local or national SEO, global search engine optimization involves targeting multiple countries and languages, which can increase costs.

    Factors that can influence prices:

    • Scope of the Project
    • Complexity of the Website
    • Services Required
    • Agency Expertise
    • Ongoing Maintenance
    • Custom vs. Pre-Packaged Solutions
    • Pricing Models

    Different agencies have different pricing models, which can include hourly rates, project-based fees, or monthly retainers. Hourly rates can range from $50 to $200 or more, while project-based fees can range from a few thousand to tens of thousands of dollars.

    The cost can vary significantly based on your specific needs and the global SEO company you choose to work with. It’s essential to have a clear understanding of your goals and budget when engaging with an agency to target an international audience.

  • How much do global SEO agencies charge?

    Global SEO agencies typically charge higher rates compared to local or smaller SEO agencies due to their broader expertise, resources and the complexity involved in targeting multiple countries or languages. The pricing can vary significantly based on factors such as the agency’s reputation, the scope of your project, and the specific markets you’re targeting.

    Here are some generalized pricing ranges you might encounter with global SEO agencies:

    • Monthly Retainers: For ongoing SEO efforts, global agencies might charge monthly retainers ranging from $3,000 to over $10,000. For multinational corporations or highly competitive industries, this fee can be significantly higher, sometimes exceeding $20,000 per month.
    • Project-Based Pricing: For specific global SEO projects, such as international site audits, global market research, or multilingual content strategy, agencies might charge anywhere from $10,000 to $50,000 or more, depending on the project’s complexity and scope.
    • Hourly Rates: Global SEO consultants or agencies may offer their services at hourly rates that range from $150 to $400 or more, reflecting the expertise required to manage SEO across different countries and languages.
    • Performance-Based Pricing: Some global agencies may offer performance-based pricing, though this is less common due to the complexities of accurately measuring SEO performance across multiple markets. The terms would be highly customized and dependent on specific performance indicators agreed upon by both parties.
    • Custom Packages: Given the unique challenges of global SEO, many agencies offer custom packages that are tailored to the needs of a business operating in multiple markets. These packages could include a mix of technical SEO, content creation and localization, link building, and local market optimization. Pricing for custom global SEO packages can vary widely, depending on the services included and the targeted markets.
  • Why is global SEO critical for my business's international growth?

    Expanding your reach across borders means adapting to diverse markets, each with unique search behaviors and languages. Global SEO optimizes your online presence to resonate internationally. By tailoring your strategy to target specific countries or languages, we ensure your brand not only appears in global searches but also connects and engages with a worldwide audience, setting the stage for sustainable international growth.

  • What kind of results can I expect from investing in global SEO Services?

    By investing in global SEO, you’re setting the stage for increased global visibility, higher international traffic and, ultimately, a stronger global brand presence. Results include better rankings in international search engines for your targeted keywords, improved engagement from a global audience, and a higher conversion rate from international leads.

    Patience is key, though — global dominance doesn’t happen overnight, but with the right strategy, it’s deginitely within reach!
