Do follow Blog comments

[sebastiankoch]

Alright,
I would like to know what do you think about this practice in general and hear some answer for my case.

My case:

I know a net of different blogs that let you put do follow comments as long as they are good. It is not really a lot of spam going on yet, around 6 comments per blog entry.

The do follow link is in the form www.xyz.com. Normally a PR 3 after the post ranks.
There are around 20 different blogs. I have already use them and I believe with good results but can´t measure it as I do many other SEO activities.

Would you recommend to get to invest time commenting in all of them? Even if all them are in the same C-block?

Please feel free to share any experience!
Thanks!

_From pure link building perspective, commenting on the same IP blogs may not be adding that much value to the link profile of your website. But do not take it this way. Blog commenting is more than just link building, it is about engagement and believe me when you are commenting on reputed sites that match the theme of your website, it can really drive real traffic to your website. So, please do not post thinks like this – “Great Post”, “Awesome mate, keep posting like” etc. You need to do post comment that adds value to the conversation. _

Well I think they do.
My competition uses this links a lot and I am talking about pr7 websites from big companies. I Doubt they bring any traffic as they are in random topics.
But do they Weight?
Is google not smart enough to know that these are comment links?

The general consensus on these types of questions has been if the audience is relevant you may see the benefits of traffic from comment readers. Does anyone know of any research into whether blog comments actually carry any link weight anymore?

I would imagine that even if there was any benefit from an SEO perspective that a couple of posts with your URL included would be enough.  Hundreds of blog posts per domain wouldn't necessarily add any more weight from a link building perspective, especially if all the domains are hosted on the same server.

When it comes to whether it is worth allocating time on the endeavour, I guess the question is whether the blogs are relevant enough to your niche that providing expertise would potentially gain you relevant traffic from the blog itself.  If the blogs aren't close enough to your industry or well respected enough then I wouldn't bother investing any real time on the matter.
