5.SEO& Internationalization

In today's Internet age, business success is no longer limited to the local market. International SEO (search engine optimization) provides businesses with a powerful tool that can help them expand their reach globally and attract more international customers.

1. Understand the importance of international SEO

International SEO is more than just translating a website into different languages, it is a comprehensive strategy designed to optimize our website to attract and serve a global audience.

Expand global market coverage

- Access new international markets and customer groups - Increase brand visibility globally - Create new revenue streams and business opportunities

Take advantage of the low competitive advantage in small language markets

- Easier to achieve high rankings in markets with less competition - Establish early entrant advantage - Obtain high-quality traffic at a lower cost

Improve user experience and engagement

- Improve the relevance and attractiveness of your website - Increase user dwell time and page views - Improve conversion rates and customer loyalty

2. Website structure and URL strategy

Choosing the right website structure and URL strategy is crucial for international SEO. Not only does this impact how search engines understand and index our site, it also impacts the user experience.

Choose the appropriate URL structure

In international SEO, there are three main URL structures to choose from:

1. Subdomain name (for example: fr.example.com)

- Advantages: Clear separation of different language versions, easy to manage - Disadvantages: It may be regarded as an independent website and it is difficult to transfer domain name authority

2. Subdirectory (for example: example.com/fr/)

- Advantages: maintain domain name authority, easy to implement - Disadvantages: Server configuration may be complex

3. Top-level domain name (for example: example.fr) - Advantages: Most friendly to local users, helps establish geographical relevance - Disadvantages: higher cost, management of multiple domain names may be complicated

But are these three structures necessary for internationalization? Obviously not, please look at Section 4.

Implement hreflang tag

The hreflang tag is a key element of international SEO. It tells search engines the language and geolocation of the page:

<link rel="alternate" hreflang="fr" href="https://example.com/fr/" />
<link rel="alternate" hreflang="de" href="https://example.com/de/" />
<link rel="alternate" hreflang="x-default" href="https://example.com/" />
```

Properly implemented hreflang tags can:

- Prevent duplicate content issues
- Ensure the correct language version is displayed to the correct user
- Improve visibility in search results for specific languages and regions
