How to create a facebook welcome page and get more fans

If you’ve read a few of my articles in the past not only are you a total legend but you are also probably aware that I give Zuckers and his team a bit of a hard time for their incessant changes that are mostly poorly communicated and largely useless.

However there are rare occasions where they do something that is pretty awesome and/or exciting and that actually makes our lives easier. These occasions are worth celebrating, talking about, writing about and overall obsessing over due to the fact they are so completely unexpected. The problem is that they are STILL poorly communicated and normal plebs who don’t devote 90% of their day to reading about social media (Ok so maybe 10% reading about it and 80% chatting on facebook) tend to miss the boat.

That is where I come in. To use one million words to explain to you something that probably ten could do, but explain it nonetheless. So here’s my latest heroic facebook information session for all of you who own a facebook page (and as I’ve outlined in my previous post about managing a facebook page, you are pretty much a loser if you don’t).
In order to reach the million words, I wish to start with a bit of a story. Once upon a time there was an evil social networking-creating genius (let’s call him Zuckers) who created the world’s biggest and most lucrative digital network. He marvelled over how easy it was to get hundreds of millions of people to hand over all their personal information and be part of this network. It was all so easy for him, despite the fact some doofkopf twins were trying to take him for all he was worth, just when he was starting to land some seriously fine ass from the whole rich and famous thing.

Anyway, because of the evil part, he decided he wanted to try and mess with these people and at the same time make it difficult for others to capitalise on his creation without putting in some serious time and effort. This is where he came up with the creation of FBML, a coding language that developers were required to learn if they wished to do anything on HIS network. It was a pain in the arse and led to nobody doing much of anything, other than whingeing.

THEN Zuckers had a particularly pleasing night at the playboy mansion and decided that maybe he would make life a little less difficult for the trillions of facebook users who were still hating on him from the latest facebook profile update. He decided he would scrap his stupid network-exclusive code FBML and let people use iFrames and HTML instead. This opened up an entirely new world for people and businesses far and wide, and one of these opportunities was the ability to create a landing tab / welcome page for facebook pages relatively easily.
