There are some things that search engines consider major spam signals and some things that they consider minor spam signals.
I am wondering what kind of effect minor spam signals can have on a website. I think that many people may have minor spam signals on their websites and not really be aware of it.
Also, how different is the impact of a minor spam signal vs a major spam signal?
Generally, we talk about major spam signals, but I think that it would also be good to know about the effects of minor ones.
