Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Prometec.net can be misinterpreted by Google and other search engines. Our service has detected that Spanish is used on the page, and it matches the claimed language. Our system also found out that Prometec.net main page’s claimed encoding is utf-8. Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.

Social Sharing Optimization

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:
