Hash tag or “#” is one of the easiest ways to search for the keywords on Twitter. It categorizes the other entire tweets by just clicking on the hash tag. The keyword should be preceded by the symbol “#”. In other words, Twitter is like a search engine. In order to search a relevant keyword use of “#”symbol is required.
For tweeting on “son” just we use “#”symbol like #son, it will show the entire related search which has son word in it. The best thing in this search is that it isn’t case sensitive; if any other word is preceded by the word son then it will not show the related search.
Hash tag is used by different people, so we can’t use the symbol “#” before every word it will take much time to tweet. So we are using “#” before any particular keyword. In the past one month “#infographic” had been tweeted for record 57 thousands times. And in the last 24 hours it was at peak of 3,365 times. Twitter has been ranked as top ten most visited site around the world. Today 88% of the twitter account holders are older adults who have not used any other social networking site.
