Visitor World Map

Country of origin for 42.2% of all visits is South Korea. It lies approximately 6830 miles away from the server location (United States) and such a long distance can negatively affect website speed, as it takes some time for data to travel back and forth between those places. That’s why one of the best ways to speed up Ocr.space page load time for the majority of users is moving the server to South Korea or just closer to the user base.

Social Sharing Optimization

Open Graph description is not detected on the main page of OCR. Lack of Open Graph description can be counter-productive for their social media presence, as such a description allows converting a website homepage (or other pages) into good-looking, rich and well-structured posts, when it is being shared on Facebook and other social media. For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
