Any experience Forum marketers?

I usually don't recommend forum marketing as a primary strategy because it sorta encourages noobs to spam a lot plus it is often a bit time consuming and you get far better results (with less effort) from other marketing methods.

I mainly browse forums to learn from people and connect with those in a similar or the same niche - but honestly, the amount time and words people spend typing up in forums can be spent writing articles instead and submitting them to a few sites and you get potentially endless traffic. Whereas in forums, if you want to 'market', you have to keep constantly being active and making sure you always deliver value.

I'll be dead honest and I'd rather not be posting on forums all day when my target marketing is hanging out elsewhere and looking for my product/service elsewhere.

However on the flipside, I do get extremely high targeted leads from forums once in a blue moon and the chances of them opting in and actually buying something has proven to be very high in my short experience.

Again, as a traffic strategy, I wouldnt recommend it as a primary method, but something one could do if they had a bit of spare time.

Forum Marketing is a very effective means of marketing if you can utilize it properly. the best thing about this marketing policy is that your product or service will become popular very soon. But the main thing is that you will never see any kind of change if you just invest 15$ per month dude
When you will be able to invest around 2000$ per month for around 8000 posts per month then you can see the effect.
I have seen people saying that they are investing 10000$ per month just for forum promotion. And they are happy because in the forums that allows banner ads and have an alexa below 2000, will cost a lot more. That's why they are doing forum marketing and getting very good response.
Ofcourse you should not take this as your main marketing source. it can be a very good substitute for Banner ads in the forums. you can increase visibility for more than 50% by investing 20% less than the banner ads.

I think Forum marketing still works well. You'll not get huge traffic, but the traffic is targeted and it's easy to convert into sales.

Just look at Fiverr and type "Forum Marketing" in the search box. There's a few people provide this service for low price.
