Maxross has it right with regards to getting in the kids.
It is an area that needs to be looked at - lots of good examples of promotion.
What advertising does the club do for matches, we all remember the posters in every chippie in town!
What school / community links are there? Do club officials and players go into schools etc? Not easy with part time players but possible. Doesn't have to be just about playing can look at all aspects - team building, leadership, motivation etc. Most schools would welcome outside speakers to look at these areas.
Are the local immigrant population at all interested in attending? Has any market research been done on this?
A local club here in Dubai gave away a Ferrari to one lucky ticket holder - the crowd did double for that particular game but not sure it made much financial sense!
The answer is of course to have a team in contention for play-offs/promotion. Unfortunately from the word go we were some way short of this and very quickly the attendance trailed off.
