Should i “dofollow” a link to Google and “nofollow” a link to my clients or sponsors? Google it is time to wake up before losing the trust from webmasters whom contributed to what you are today. Have Google ever wonder what will happened if one day more than 60% of the sites block googlebot with their robots.txt?

If you use a subscribe to comments feature, if a spam comment gets through, it goes to everyone on the email subscription list before the blog post author has a chance to moderate it.

Spam complaints can do nasty things to your internet business, can can even affect other people.

If for instance AOL decided to blacklist a site, then it is quite likely that any RSS article, delivered by email, that contained a link to that site would also end up in the spam folder.

This type of thing frequently happens with large affiliate promotions. It is one of the reasons many affiliate managers insist that affiliates use their own redirect in emails, or register a suitable domain name to cloak an affiliate link.

The ladder would be very radical and I don’t suggest it to him.

I don’t know if SEJ is authority enough, like Wikipedia, to have the Search Engines take notice.

It would harm him, as an individual too much, if they don’t. A risk that is not worth taking.

p.s.
I get an email for every comment that slips through the spam filter and check it. If it is spam like the one a few minutes ago for this post, I delete it.

Whilst I haven’t been a regular reader for long, I don’t recall seeing any pure spam comments, so there is a relatively good barrier, though there are always ways to improve that.

My biggest worry on spam comments isn’t whether I am linking to a bad neighbourhood but whether a subscriber to comments would end up with a spam message that didn’t get filtered.

I have added subscribe to comments, I just need to find time to hack the plugin to make it CAN SPAM complient, so if a blue pill comment does make it through, at least I have something to stand on.

You are actually one of the people who requested the ability to subscribe to comments

One reason to use nofollow is to prevent linking to bad neighbourhoods. I control that using a comments policy. If someone abuses it they lose their ability to comment.

Another use is controlling link juice within a domain.

I don’t think it should be expanded, but I do think it shouldn’t be used under any circumstance where someone is citing your content, or aggregating it in some way.

As for commercial links, that should be handled by disclosure and your relationship with your readers. Google are the only company that I am aware of that have unofficially suggested the use of nofollow for commercial links. It is something I won’t do until I can effectively disclose that I get paid for referral units.
