By using the Facebook tracking pixel or the Adwords pixel, you can help to define your audience and work to entice them to come back to your site.

According to Facebook, your cover photo is displayed at different sizes on desktops and on smartphones — 820 pixels wide by 312 pixels tall on desktops and 640 pixels wide by 360 pixels tall on smartphones.

I have a couple of questions re the above training and comments as i was keen on using facebook to promote my site. First point is that the training, from the comments list, is over 3,000 days old which means it is almost 10 years old the world and facebook has changed a lot, has the training?. Also i tried my first ad for facebook and it got rejected i find that the dating niche is not a facebook acceptable product. Has anyone achieved getting their advertisement onto facebook in this niche?
We’ve come across many well-meaning marketers and entrepreneurs who create personal profiles for their brands, instead of an actual Facebook Business Page. That puts you at a huge disadvantage -- you’re missing out on all of the content creation tools, paid promotional opportunities, and analytics/insights that come with a Facebook Business Page. Plus, a personal profile would require people to send you a friend request in order to engage with you, and the last thing you want to do is make that more difficult for customers.
