Someone e-mailed me and asked if I was interested in putting a link of their company in one of my blog posts. They said they would be willing to pay me about $100 for it.
It's an one time payment and not an advertising deal where you have to put a banner or link on the homepage. It's just a link within one of my posts.
They said they are trying to promote their website and get backlinks.
Is there a catch? Sounds too easy.
