Good evening friends, how can I ensure that the posts I share on my WordPress-based site are automatically published on the site’s Facebook page and Google Plus page? I looked online but couldn’t find satisfactory information. If you know of any plugins etc., it would be much appreciated 
I think the pro version of the Snap NextScripts plugin does it. You should look into it.
Thank you, teacher, I will look into it a bit.
In a word, Jetpack. Install the Jetpack plugin and configure the sharing settings; you can share not just on Facebook and Google, but also on Path, Tumblr or whatever it is, and on Twitter.
I am installing Jetpack but it gives a connection-related error and won’t install, sir.
Configuring settings in these kinds of plugins can be tedious, so put some effort into it. If you have an issue, state it clearly, let’s see, sir.
It’s next to impossible to have a problem. I must have installed it maybe 100 times and never had a single issue. Try working on it a bit, if you can’t find a solution, write in detail and I’ll try to help.
Sir, I am getting this error in Jetpack
