Even if there are many competitors and a lot of companies using the signatures campaigns for their promotion on bitcointalk, those signatures are still visible and make an impact. If the people were attracted to the signatures and sites did not get traffic from here, then why would companies continue to promote their business through signature campaigns.
I think the signature campiagns is a effective way to promote the business and SageSwap is doing it perfetclty right.

Yeah, sig campaigns have existed on this forum long before I created my account, ff course, back then I didn't understand it very well, nor did I know that users were being paid for giving up their space in the signature. If this model continues to this day, it's because, as long as it's a long-term investment (1y or more), it pays off, perhaps not in clicks on the links of the signature, but in brand recognition and reputation building. As long as the company remains reputable and doesn't block withdrawals or do anything else suspicious that could tarnish its reputation, the sky's the limit.
When I first saw Sageswap presenting themselves on another forum, I immediately noticed their dedication and quick responses. These guys are good, and if the volume has increased, they deserve it.
Do campaigns really help that much? Swaps probably do, but if another site that isn't a swap site launches a campaign, does that work well too? I don’t know if it has such a good impact on profits, people here are broke, and many of them are guys from India or Nigeria who have 20 accounts each to make money from campaigns. I’ve noticed a few accounts that are linked to each other, maybe I’ll make a thread about it somedayy
