WordPress Multilingual Conversion: Don't Be Confused by Surface

Many webmasters think that WordPress is very simple and just throw a plug-in into it. This is not the case, this thing is so deep! In this article, let’s take a look at the things that WordPress multi-language conversion, so that you will no longer be confused by the simplicity of the surface. After reading it, you can not only easily get a multilingual website, but also avoid many pitfalls and avoid many detours.

Let’s talk about the conclusion first: There is no absolute good or bad for WordPress’s multi-language implementation solution, only suitable or not. When choosing a plan, consider your website size, budget, technical capabilities, and most importantly, your actual needs.

Basics: Don't confuse language packs with multilinguals

Many newbies confuse language packs (such as translating WordPress backend into Chinese) with multilingual websites. The language pack just translates the interface, and your content still has only one language. A multilingual website means that your website can provide content in multiple languages ??at the same time, and users can choose their favorite language to browse. This is the focus of our discussion today.

Core: Analysis of the advantages and disadvantages of several mainstream solutions

There are mainly the following mainstream WordPress multilingual solutions on the market:

• Plugin solution (WPML, Polylang, etc.): This is the simplest and most crude solution. Install the plug-in and configure it to use it. It is easy to get started. But the disadvantages are also obvious: performance issues, especially large websites, the overhead of plug-ins will be very high; many plug-ins are paid and costly; plug-ins update and maintenance also need to be considered. I once used WPML on a large e-commerce website. Post-maintenance is a nightmare and performance issues are even more troublesome. If you are just a small website, it’s okay to play with it, but if you use it with a large website, be careful!
• Multi-site solution: This is a relatively elegant solution. Each language version is an independent site and is managed using WordPress's multi-site functionality. The advantage is that the performance is relatively good, the disadvantage is that it is more troublesome to manage, you need to be familiar with multi-site configuration, and SEO also requires additional processing. This solution is suitable for teams with high performance requirements and sufficient technical strength.
• Custom code solution: This is the most flexible and complex solution, and you need to write your own code to implement multilingual functions. The advantage is complete control and best performance, while the disadvantage is that the development cost is high and strong technical capabilities are required. This is suitable for large projects or scenarios with extremely high performance requirements.

Code example (Polylang plug-in is an example, for reference only. Please refer to the plug-in documentation for actual use):

Suppose you have installed the Polylang plugin and added two languages:

 <code class="php">// 獲取當(dāng)前語(yǔ)言$lang = pll_current_language(); // 根據(jù)語(yǔ)言顯示不同的內(nèi)容if ($lang == 'en') { echo 'Hello, world!'; } else { echo '你好，世界！'; }</code>

This is just a simple example. In actual application, you need to deal with various complex scenarios, such as translating custom fields, processing URLs, etc.

Advanced Usage: Don't Forget SEO

SEO of multilingual websites is very important. You need to configure the hreflang tag to tell search engines the relationship between different language versions of your website. In this regard, many plug-ins can help you automatically generate, but you'd better check it and make sure it's correct.

Common Errors and Debugging: Beware of Hidden Pits

• Language conflict: There may be language conflicts in different plug-ins or topics, resulting in display errors.
• URL structure: Different language versions need to have different URL structures, otherwise search engines may consider duplicate content.
• Database pressure: The database pressure of multilingual websites will be relatively high, and database optimization is required.

Performance Optimization and Best Practice: Speed ??is Everything

• Caching: Using cache can greatly improve website speed.
• Database optimization: Optimize database queries and reduce database pressure.
• Code optimization: Write efficient code to reduce server load.
• CDN: Use CDN to speed up website loading speed.

Finally, remember: there is no perfect solution, only the most suitable one. Before choosing a plan, be sure to weigh the pros and cons and choose the one that suits you best. Don’t be confused by those fancy advertisements. Do more research and try more to find the WordPress multilingual solution that is best for you.
