## L10n Coverage

• L10n coverage

Definition: L10n coverage is a measure of the percentage of our visitor base that get served with KB articles in their own language. It's calculated by taking into account the English top 50 weighted by the localization status of an article and the the number of visits for each locale.

Edit levels are taken into account as follows:

• A level 2 review change drops the localization to 50% of the article
• A level 3 review change drops the localization to 0% of the article
• More than one level 2 review change drops the localization to 0%

Example:

• German makes up 10% of our visitor base
• The 'how to set your home page' article makes up 2% of our top 50 visits
• When the Home page article is the only localized article and it's up to date in German, then our overall coverage is 2% of 10%=0.2% overall (+ the English coverage)
• When German misses a level 2 change, the coverage drops to 50%, so 1% of 10%= 0.1% overall
• Important: Currently we are using a simplified model, where each article accounts for 1/50=2% of visits per language
