How Localization Impacts Page Speed, UX And Conversion Rates?

What do you think if a visitor visits your website and finds that the content is not understandable to them due to a language barrier, will that person stay or sign out?

This happens with the majority of global shoppers, who want to purchase a product but leave the shopping in between as they couldn't read the descriptions, website content, blogs, etc.

However, the scenario is changing in 2025!

The websites are entering a new phase, where they are built on the principles of multilingual content, cultural nuance, and performance engineering.

Let's find out more in our blog about this ecosystem.

Why are Websites Moving towards Localization?

Earlier, it was a trend to build the entire website in English, as it is termed as a global language.

However, the recent findings reveal that people are looking for their preferred language on websites, due to which the consumption of English content has slid below 50%.

Moreover, 76% of people are comfortable with their native language, and when they open their devices for online shopping, they prefer their mother tongue.

Additionally, 40% of customers don't buy products or services when they see the content in another language.

The data is not ending here! Even B2B leaders agree that at one point, 96% of business is derived when the content is in the customer's preferred language.

Keeping Page Speed in Mind

Google makes regular updates to its Core Web Vitals. Recently, it has included a fresh feature known as Interaction to Next Paint (INP).

Under this, if a website's loading time is under 200 ms, it will be considered for a "Good" rating; otherwise, the scenario is not in favour of the website.

The other published metrics are:

• An e-commerce website can achieve a conversion rate of more than 3% if its page speed is one or two seconds.
• If the above website is taking more time to load, the conversion rate takes a hit.
• The customers who are searching for products on mobile or other devices only wait for a maximum of three seconds.

Localization + performance = Powerful results

When companies apply localization to their websites, they can extract robust results. Let's see how it can be achieved. 

Below are main points, which show the impactful behaviour:

1.1 Should you focus on content quantity or content quality?

Undoubtedly, when you add external elements to your website, such as HTML, CSS rules, and larger image sizes, it will increase the page loading speed.

However, you can follow the steps below when the correct localization strategies are implemented:

• In terms of component-based frameworks, they can load language from JSON to show to the customers.
• WebP images have lower weight compared to other formats, such as JPEG and PNG. Furthermore, they take up less disk space.

1.2 A proper focus on hreflang and SEO

When there are correct hreflang markups on a website, the website won't have duplicate content penalties from search engines. This is because search crawlers have limited time to perform indexing, and when they see that there is no duplicate content on the website, they push that page to a higher rank.

1.3 A vital part to add: Edge rendering and geo-caching

Nowadays, companies are applying edge rendering in their websites, as they want to show the preferred language to the user and, at the same time, keep the page loading speed below 200 ms.

Undoubtedly, languages such as Chinese, French, and Japanese are difficult to load due to their size, but the path becomes easier with edge rendering.

Localization is the Best Friend of a UX

UX and localization go hand in hand. The prior has to follow everything with the latter to provide the best experience to the users.

Below are the important facts:

• There should be a logical reading order for the user. For example, websites providing their products in the Middle East need to follow right-to-left for Arabic users.
• Global users buying products and services from a website and getting numbers in local currencies.
• Using cultural imagery and color symbolism to show respect towards the users. For instance, Western people easily recognize red as a symbol of discounts; however, the same color is seen as a symbol of good luck in Chinese.

Localized Content Bringing more Customers

How much can a website achieve in terms of selling a product? It's 202%.

Customers prefer to shop in their own language, and when they find the usage of currency and cultural references on the website, they are inclined towards it.

Shopify published a report stating that 10-15% more sales happen when companies prefer localization in their work.

What does the data say?

• The company adopting localization with the power of artificial intelligence can increase its conversion rates by 20%.
• The loading page time for landing page design having localized content can be reduced by 12% in the e-commerce ecosystem.

What Steps Make a Localized Website Unique?

Discussing the important steps with you so that you can apply them to your website.

Go with edge internationalisation on the website

Select lightweight headers that are extracted from the JSON bundle. This process will happen before the content reaches the browser to keep the Largest Contentful Paint (LCP) under control of 2.5s.

Use the right elements for media files

If you want to implement an image on the website, you should adhere to the <picture> element so that less space is taken by the media files.

Don't forget INP

The time has changed as companies are not leveraging render-blocking translation scripts. Instead, they are interested in building with their localized website with asynchronous hydration.

Keep your website loaded with translation memory & caching

When companies use translation memory, they can witness a drop in duplicate strings by up to 40%.

Keeping a close watch on core web vitals

Always keep a check on the content part where people are interacting more. For example, Apple Inc. is a global company and can view from which region, which type of people, and with which language are interacting with their website. Additionally, are they buying anything or visiting websites only for window-shopping?

Final Word
