To target meat products, there are a number of ways to do it:
1) create loads of Facebook groups that focuses on mancaves/hunting and use them as your lla
2) target men with families that have a high affinity to online purchases - your pixel will eventually start ruling out vegans, of which there will be scarce in any case using this setup
3) if your client generates sales via other traffic, take their emails and create a lla
4) if your client doesn't generate sales via other traffic, buy native/gdn traffic and place your fb pixel on any cta button on the clients page. Let that build to around the 3000 mark (won't cost much if you use a button in one of the earlier steps like 'find out more' cta) and create a lla
5) if the client can, make their meat produce farm purchased or organic (although licensed organic is a difficult process), that has actually helped approvals for one of the clients I did some work with.
6) finally if none of that works, give up and shoot yourself because you can't do fb ads

(at least 1 of the above should work...)
