What is a "Facebook Pixel" and how does it work?

I am pretty sure a developer created and configured my Facebook page with a "Facebook Pixel" but I am on my own now, and need to understand it better.

How do I find it if it does exist? What does it do exactly?

Is there an email address associated with it? If so, can I find what that email address is?

Secondly, I am trying to connect it to an EverWebinar, so when the Facebook user clicks the "Sign Up" button on my Facebook ad, the sign-up page pops up. Does this mean EverWebinar also needs to get that pixel?

What does a Facebook Pixel file look like?

Thanks

Is there any way of setting LinkedIn to automatically accept all connection requests without me having to manually accept them?

Hi Experts,

In order to add a  FaceBook  link to a website, I linked to https://www.facebook.com/abccompany/; for LinkedIn https://www.linkedin.com/in/abc/

Does anyone know how to do this for Wechat, or if it is possible? Truthfully I have never use Wechat, and guessing you need a user id. How can I instruct the client to get that ID?

Just wondering

What is SMM?

We have a user that created accounts in Tweeter, Facebook, Instagram. Linkedln and Pinterest some time ago but never used it.  Just this week the user wants to start but noticed that wants to change each tags (or reference name like @sample_name) per apps, and the email used to create it.  

What's the best way to go about it?

Hi,

As the subscription costs really add up over the long haul, we plan to cancel our LinkedIn Recruiter Lite account over the summer months and resume it again in September.

If we do  this then we will get an empty account when we resume in a 4 months' time. This is grossly annoying as we lose all of the data we have paid to generate over the past few years.

Of course we can save the primary data by downloading CV's, but we lose items like stats on how many applications, and when, Groups candidates are part of, the ability to filter candidates by; Location, Company, Job title, First name, Last name, Years of experience, Education, etc.  Plus we lose the useful recruitment interface that they provide to view that data.

Although LinkedIn does not advertise the fact, I have a feeling that it is somehow possible to download all of our data.  It is our data after all, plus we have paid significant number of thousands in subscription.

How would we download all of our data from LinkedIn Recruiter Lite?

Thanks,
Robbie

How does sharing to social media work?  If I put an icon on my web page to Share to Facebook, what part of the page gets shared,  where does it show up on Facebook and whose Facbook page does it show up on?

Thanks

How do I turn off Facebook notification 'You have a new friend suggestion" ?

I checked their support site.  Either they don't want me to know how to turn that off or there is no way to turn it off?

I went to Settings > Notifications.  Didn't find anything about that.  I tried hovering my cursor over the specific notification but my only option is to hide the notification.  I want to stop these notifications from happening.  There must have been a Facebook update or enhancement with this feature because I didn't used to get them in the past, but in the past few weeks I've been getting them way too often.

I guess if there is no way to turn it off I'll have to try disabling all notifications.

What are your thoughts, ideas, solutions?  Thank you.

I want to upload photos on social media from my Google Drive account without having to download these photos on my computer first. Is there a way to do this?

If I tweet a link Twitter automatically picks a picture it embeds into that tweet. Is there some way to point out to Twitter (and perhaps also all the other social media sites Facebook, Instagram, ...) what picture to pick? Especially when you not integrate the typical set of social media buttons offering to post about the page, but if someone just posts a link to say a blog article? Is that perhaps simply the biggest picture detected to come from the same origin?

And if there is such a mechanism, can you even tell twitter to rather not display some picture, especially with a webpage not so well known and mostly textual, where the most prominent picture rather is a site logo only?

As one example I see links to Quora answers having pictures not even part of that answer as if there is some hidden tag or meta info as an official way to tell social media what picture to embed. If there is, how does this work generally? When something applies to Twitter, does it also apply to Twitter apps like HootSuite?

That's a bit fuzzy question, but I'd take any helpful hint on social media optimization. Is that a thing at all, aside from SEO?
