Personally, I do click on some links that interest me, but I wanted to know if anyone else in the community thinks that these campaigns are worth it for the company(s) paying for these.
Thoughts?
I am sure that theses signatures are doing what they are supposed to. These people wouldn't be giving away money for all this time for nothing, so it must be working.
Also, this is easy to check. Site operators can easily compare hits and number of accesses before the signature campaign and after some time with signature campaign running and then they would have a clear picture.
True. Also, some signature campaigns post a referral link onto their signatures so that whoever signed up under it would have directly signed up from clicking the signature. It's sometimes inaccurate, though, as some people might note the website down and visit it later directly.
