If they are bothering to put up a link, then at least I can take a minute to visit. That's especially true if the person made a really relevant post.
However, on some occasions, even when the signature line promised something really enticing, the website that it links to is just bad quality.
On one particular site that I visited via a signature line, most if not all of the articles were not related to any common theme and ranged from TV shows to marketing.
This was not someone's personal blog but more like a weird assortment of random advertisements on each post.
I am only assuming the blogger was selling posts to others or just didn't know how to create a good blog.
Not saying this to be judgmental, but it put me off their blog how they could not stick to at least one generalized niche.
What bothered me most was how the signature line promised one thing but there was no mention of that on their blog.
Not sure if anyone else is coming across this issue but it brings up questions as to why people are not using their signature line more effectively as truly sometimes these things do get clicked on.
You can't just have a great signature line and then fail to deliver for the person who takes time to click through.
Observations, tips, tricks welcome on this subject.
