I can talk of personal experience I've done a couple of rather "large" German game pages for games 10 years back.
If this is one of your first pages than I can only say (and I don't want to discourage you) it’s very very hard to do an busy games page and a lot of factors play a roll.
Actually I want to be honest with you and say forget a WOW page it's practicly impossible, unless you provide the community with something no other page can.
10 years back I picked up a PC Gamer saw a small note in the mag that they are planning to do this game, went out and bought the domain even when I had no info about the
Game and the official page wasn’t up.
The page became very very fast very busy, but only because there was nobody else around or the other pages were English.
As soon as the game was covered by a larger Article I saw the first pages creep up from people that had a lot more experience, they were clever and looked for hosting from a large
Online Gaming page and BAAAAAM they had all the users etc.
Over night all my hardword was done and gone, I never forget how disappointed I was back than.
All I’m saying is
Yes Games pages are very good for starting an easy page (IF YOU START EARLY ENOUGH) and ensure that with very little promotion you can get a very busy page very soon, however it’s very hard to keep the
Visitors active when the game is out and there are a lot of Pages out there that always present the user with the same content.
In other words it’s a harsh environment to start.
You have a WOW page, now I have been working with Blizzard (I was employed for a over 6 years in the games industry) I know a WOW page is probably the hardest page to do beside maybe EVE online.
There are literality millions out there and you have to fight for every user.
Here is what I would do and god I really don’t want you to give up but maybe you can do that beside the wow page.
Go by the next PC gamer check out the webpages, try to find a game they talk about but were there is no webpage out there, try to cover all angles, buy a good domain name, most of then direct domains Gamename.com are usually taken, but there are tons of good ideas.
Than build up the page install the Forum (ONLY WITH TWO SUBBOARDS NOT 1000 DIFFERENT SECTIONS) than next contact the Developer and the distributional and make them notice
That you have the first fanpage, than it’s all about a little sensible spamming in game boards.
Here is a very good thing to get traffic and loyal user, when you start your relationship with the Developer (and trust me they are glad for every fanpage out there) you have to gentle advice them that this is not a one day thing for you, that you are committed to this idea of yours, write them regularly, every Games developer has a Commuity manager, write him often enough so he knows your name but don’t spam.
Next you do is to get an agreement for an interview or even better try to travel to them take images or any content that is exclusive to you is GOLD, that means all the other games pages have to link to you the users will see that you are the man to get info and they tend to check your page much more often.
You have to be aware that a Games page is very labor intensive, I had countless of people “working” for me but most are just lazy and want to see their name under their post once and than forget about it.
It takes a lot of determination and hard work to build up one of these cool games pages everybody wants to post on.
You need to update the page all the time, especially at times of release it becomes crazy and the community is buzzing, that is the time when most Gamers even jump ship and go to another page, maybe the board is better or the community seems cooler, it’s all very very hard and complicated.
I would start alone do not give into the temptation to make the first guy who posts on your board Mod, write all the articles yourself all the news, become a near mystical figure to these guys and than when things get very very busy you start recruiting.
