One advantage we offer over other sites is that we are dedicated to helping clans finding new members, and helping new members finding new clans. This means we are trying hard to offer you a way to present your clan with minimum effort for maximum impact. This basically means we are forcing each clan to present their information in the same way, so that potential new members are able to filter out interesting clans instantly, as in these modern days you really have to fight to grab a users attention. Our idea is that you have 15 seconds to grab a users interest, which is why we are using images to immediately associate a clan to a platform and to games they are playing. This is of course only part of the tools we are using, but among the most helpful ones.
Our biggest challenge is to show off the potential exposure you get by posting here, as we are getting very specific traffic from Google, namely people looking for a clan. This fact is not reflected by the activity, post count or member count here. We try to alleviate this by showing off our search stats, sharing what games are trending on this site (in terms of search traffic) etc.
You should try to show off what makes your clan unique and awesome. If you have requirements, include those high up in your description. To put it simple, think that you have 15 seconds to gain a users attention, and then work from that.
Also, if you just create a topic and leave it, you are indicating that you don't care. We are getting 80 - 90% of our traffic directly from Google searches, and all of our top searches are related to finding a clan. If a user looks at your 2 month old topic, then check your profile and see you haven't visited for the past two months, why should they bother contacting you, when there is a similar clan that posted here 2 weeks ago with a recruiter online now? It is all about choosing your venues and staying visible and active. This is something we see often, people just creating a topic here and after two days are wondering why it isn't working. It is simple, you are not guaranteed any members regardless of where you are posting, but by staying active and visible will increase your chances, regardless of where you decide to post.
