International SEO in 2025: What You Need to Know

Is expanding your business globally one of your 2025 goals? Or maybe you’re already targeting multiple regions or countries, but not achieving the expected results? If so, you need an effective global SEO strategy. We’ve put together this handy international SEO guide to help you get started.

What Is International SEO?

International SEO is the process of optimising your website or page so that search engines understand which countries you’re targeting and which languages your content should be available in. 

This involves adapting the website’s technical structure (such as URL format and hreflang tags) to support localisation, but also creating content that aligns with the culture and expectations of each market. This could mean adjusting tone of voice, using region-specific keywords or even using visuals that better resonate with users in each location. 

Local SEO vs Global SEO:

While both local and global SEO aim to increase your website’s search engine positioning and traffic, local SEO focuses on a narrower geographic location, whereas global SEO aims to attract a wider audience. Which strategy is more suitable for your business depends on its unique goals and needs.

For example, if your business largely relies on foot traffic or word-of-mouth referrals, pouring resources into an global-focused strategy would probably not be worth it. But if you’re noticing demand for your services or products abroad, global SEO can help bring the right audiences to you, increasing conversions and helping you grow.

Benefits of Local SEO:

• Helps you focus on a narrower geographic area, perfect if your target audience is concentrated in one region
• Consistent local listings build credibility and trust with the local community
• You’ll come up in results for people actively looking for services in your are

Benefits of International SEO:

• By optimising your content to different regions, you connect with target audiences you would’ve otherwise missed
• Appearing in global searches improves brand recognition and credibility on an international scale
• Tapping into new markets increases your revenue and helps your business grow

Your 2025 International SEO Checklist

Here’s a checklist of the main considerations you need to keep in mind to increase global rankings for your website in 2025:

• Language & Localisation in International SEO:

In addition to translating your content to the relevant languages, multilingual SEO involves incorporating any local idioms and dialects, as well as cultural references that might resonate with the target audiences.

• Cultural Nuances for International SEO Success:

Buying habits, cultural norms, and holiday seasons that are unique to each market can all influence the way a target audience interacts with your website. Research those to make sure your content is aligned with local preferences.

• Audience Profiling for Effective Global SEO:

Demographic insights about each of your target audiences can help you create relevant content. Consider age, location, and common interests. Looking into user behaviour statistics, such as device usage and social media preferences, can also help. 

• Global SEO and Local Business Listings:

Optimise content for relevant international search engine platforms and online directories. 

• Keyword Research for Global SEO Campaigns:

Use tools such as SEMRush or Google Keywords Planner, making sure to select the relevant region.

Don’t assume high-volume English keywords rank well internationally. This is not always the case! Make sure to see what searches are popular in the relevant languages. 

Terminology can differ across regions as well, even if those regions speak the same language. For example, Canadians and North Americans may use different terms for products/services compared to the UK.

• Technical Setup Tips for International SEO:

You have a few options as to what URL structure to choose for your international site. You could use a subdirectory (e.g., website.com/uk) for different languages, as those are generally simpler to manage. Country code top-level domains (e.g., website.uk) are also a great option, but tend to require more resources. You could also choose to place internationalised content on a subdomain (e.g., uk.website.com).

Using IP analysis to adapt the content is not recommended, as it makes it hard for Google to crawl the variations of your website. Have a look at Google’s official overview of international and multilingual site topics for more information on this.

Finally, don’t forget to add hreflang attributes to clarify language/region pages and use the correct currency database so visitors see the correct pricing.

• International SEO Legal Considerations

Make sure to stay on top of any local regulations regarding data privacy and website practices. For example, in the UK and Europe, you’ll have to comply with GDPR (General Data Protection Regulation), whereas Canada enforces PIPEDA (Personal Information Protection and Electronic Documents Act).

While there is a lot that goes into global search engine optimisation, the above international SEO best practices are a great starting point for building a good international targeting strategy.

Creating a Global SEO Strategy

If you’ve decided that global search engine optimisation is the right step for you, but aren’t sure where to start, take a look below at some international SEO strategies that can help you lay a strong foundation:

• Define Your Markets

Think about where exactly you’re aiming to expand and why. If you’re not sure, look into your current website analytics to see where most of your international visitors are coming from.

• Market Research

Get a good understanding of the markets you plan to target. What buying habits do the locals have? What is the average income level? Are there any regulatory specifics you need to consider? 

• International SEO Keyword Research

If you already have some SEO experience, you’ll know the first step is to identify your keywords. Once you’ve done that, translate and adapt them into each of your target languages. Keep in mind that sometimes, the most popular local searches may not be direct translations. 

• Creating Localised Content

When creating your content, adapt your tone to align with the relevant culture. This will set you apart from competitors using a ‘copy and paste’ approach.

• Building Local Authority and Links

Search engines results are affected by local relevance. To improve yours, try submitting guest posts on local blogs to gain backlinks, or collaborating with local influencers, for example.

How to Do an International SEO Audit

Monitoring how your content performs will help you notice and fix potential issues, as well as continuously improve your strategy. 

Using tools like Google Analytics, you can see which countries and regions are driving the most traffic, and whether you’re attracting the right audience in each market. 

Another aspect of auditing your international SEO content is reviewing localised keyword rankings. If any of your keywords seem to be stuck, look into how competitors ranking higher are approaching those keywords and use that information to create your strategy.

Comparing your pages to top competitors will also clue you in to any content gaps. Are there any keywords you could be ranking for, but are missing out on? 

Common International SEO Mistakes to Avoid

Succeeding in international SEO can be tricky. To help you make sure your strategy works, here a few common international SEO mistakes to watch out for:

• Not using hreflang tags: These tags tell search engines which language and region a page is for. Without them, you risk showing the wrong version of your content to users.
• Ignoring mobile optimisation: In many countries, mobile usage dominates the market share. An unoptimised site can hurt your rankings (not to mention frustrate visitors).
• Skipping local research: Each market is different, so without proper research into local preferences, competitors and search behaviour, your strategy may fail.
• Using the same content for every market: Even if well translated, content that isn’t culturally or contextually adapted can fail to engage. Keep in mind that what works in one country may be irrelevant in another.
• Assuming one domain structure fits all: Choosing between subdomains, subdirectories or ccTLDs can impact SEO performance in different markets. Instead of sticking to a one-size-fits-all setup, evaluate your international goals to avoid limiting your growth.
