To help small businesses connect with relevant customers online, Google has introduced "Smart" campaigns which allow them to create ads in minutes.

Aiming to get more people to interact with its "Stories" in the main app, Facebook has added group chat and reactions among others to the service.

To address the problem of increasing spam accounts and trolls on its platform, Twitter has introduced tough policies that will soon see some users losing fake followers globally.

To address abuse and trolls on its platform, Twitter has introduced new policies on hateful conduct and violent extremism, including a plan to bring in new technology and staff to fight spam and abuse.

Facebook said on Tuesday that it is taking steps to ease a January policy banning financial products and services associated with cryptocurrency.

Facebook has hired a team of ex-intelligence officers, researchers and media buyers to find the worst possible things that can be done using the platform and to help the company prevent them.

Facebook has reportedly introduced a new feature, tentatively titled "Your Time On Facebook", that would provide information about how much time users spent on the platform each day in a week, along with the average time spent on the site per day.
