; that is why I believe that these signature links work as backlinks that help mixer projects to get indexed on Google pages, right?
That's not very effective for Google indexing. However, for backlinking purposes, it might help to some extent. Still, effective backlinking usually only works if the campaign lasts for a long period, at least a year or more, because once the signature is removed, the links disappear as well, reducing any long-term benefit.
This is possibly the reason why companies that understand how this works usually opt for a long term campaign, because they know that the more the campaign last, they more beneficial it becomes to them..
And i can't remember the exact place but I know I've read somewhere where the manager of this campaign said that mixtum campaign this time will be running for a long term, though I understand long term may likely mean different period of times for different people but let's hope it's for over a year, and let's also pray and hope that government become more friendly with mixers and clampdown on their site anymore, then we have the assurance that legitimate mixers that are here to provide long term service will freely operate without any issues from regulators.
