25. Explain about OG Tags?

The OG stands for Open  Graph. It is on Facebook and Twitter. It was introduced by Facebook in 2010. The OG allows people to build their identity based on their likes on various interests. You can read, watch the thing that you had liked. Therefore, the information travels from the third party website to Facebook. Example, if you watched a movie, the name of the movie may appear while you are on Facebook. If you had searched for an institute, the time you open the Facebook, you can get pages related to it on your timeline or newsfeed.  The OG tags can help the Digital Marketing experts to track their website visitors easily.
