A signature campaign is good, but it is not always the first resort for some companies when they come to the forum, even though they may have the finances to run a signature campaign for a period of time.
The signature campaign is not always as effective as you think for every company, and for some companies, they will like to try out other methods of marketing and promotion before they start a signature campaign.
There are many factors those are can be the cause for not effective but in this forum when a project arrived First of all they need to gain the trust of forum users first and I think there is no another way that can make the visibility and trust on forum rather than the signature promotions.
But when comes to effectiveness of signature campaign it should be long-term, and In this case it can be seen that many times short term signature campaign strategy is not effective. And in this case HunnyFinance already have a 9 weeks running hope they will make more stronger marketing in this time.
