Ads are very important for webmasters because they can help them earn money and increase the number of visitors and popularity of a website. Google developed a service that is now very popular, helping thousands of web developers earn money with their webpages.

Google AdSense is a solution that will allow every publisher to post ads on their websites and, with every click coming from a visitor, he/she will earn money from the search giant.

If you own a Google AdSense account, you need to setup your website's language, to help Google post specific ads on your website. When GoogleBot crawls your site it also verifies if the language selected by you correspond to the content of your website.

Today, the search giant said that 4 new languages were added to the Google AdSense service, so publishers are now able to place advertisements in their mother tongue.

"We're excited to tell you that AdSense for content is now supported in Croatian, Czech, Slovak, and Traditional Chinese. If you manage a site in one of these four languages, you can now complement your existing AdSense for search boxes (and revenue) with contextually-targeted AdSense ads!

To get started with generating your AdSense for content code, just visit the AdSense Setup tab in your account. Please keep in mind that after you add the ad code to a new page, it can take up to 48 hours for our crawler to access your site. Once your site has been crawled, our system will automatically detect the primary language of your pages and serve targeted ads in the correct language," Arlene Lee, AdSense Publisher Support, said.

So, if you intend to place advertisements in one of the languages mentioned above, all you need to do is change the settings in your AdSense accounts, publish the HTML code and then wait until GoogleBot crawls your website.
