Yeap - I’ve noted from our FB stats, when something is shared by one of the community groups, our page gets way more hits than when we’ve had then from paid for marketing!
Also, having a good alumni network is quite effective. It doesn’t necessarily work via targeting cadets directly - but by targeting parents and family of cadets. We don’t have a current formal alumni network - but we’ve got a number of ex-cadets who constantly like and share stuff we post - and when they do, our digital footprint grows.
Keep the FB stuff current, interesting and relevant. A few years back the broader ACO (as was!) had the strap line “what did you do last weekend?” - exploit this via social media by showing the diverse range of stuff we do actually do! It doesn’t have to be a whole squadron effort - but one cadet going on band camp, somebody going to a Wing shoot, or a potential NCO going on a JNCO can all be worded to get good coverage. A couple of snaps of the cadet doing something interesting or a portrait photo (not a selfie!) adds value (and will increase your page hits). From about a month prior to an intake add the “you can join us on [dates]”.
Utilizing lessons learnt from the behavioural insights team, falsely generate some demand - “book your place on our intake evening - only 10 places left”. Even if you’ll happily take anybody, having a “booking” system, or making you look more popular than you actually are works wonders at encouraging people to make contact and book a placet! It’ll also give your training officer the heads up on how many people to expect and how to resource it properly so you can convert interest into a cadet.
Then get it shared across your local community FB pages. Even via the local rag FB pages if you can - they might even put it in the paper! This is easily done - don’t rely on doing it organically. Make contact with your local pages (most towns and villages have a few - be it a “Spotted in” one or one of the more formal ones. We’ve got those, a formal FB group, a local online newsletter, a “community vision” FB group, buying selling groups and a community “whats on” guide. I’ve also persuaded the local town, parish and LA facebook pages to share stuff. A much bigger footprint without giving Facebook your cash!
By all means get the RFCA, RAFA or RBL to share it - but you really need to target your local community pages to get the local audiences. And, as @Teflon says, don’t make the wordology target the cadet group - it’s the domain of teenage saddos (apparently!). Target the parents and grandparents.
But use this as one part of a series of recruitment tools. Doing it in isolation isn’t going to work.
