No follow and do follow

how do you find out what is what? is there a code you look for to find out which one is a no follow blog and which is a do-follow blog? what are the things you look for?

Most blogs are default to nofollow.

While I've never heard of any tool avaiable to find blogs that allow links... it is overwhelmingly a worthless endeavor.

Just because you find a blog that allows links what makes you think you comments won't be seen as spam... surely you're not planning to be an active contributor of each blog you find, but in context you'll need to be seen most blogs that are worth "anything in link juice" screen for spam posts and delete them...

Be that as it may you are seriously wasting your time think that you can get even a fraction of link juice from blogs without any contributing value/effort.

ok, thanks for the advice, thats why I needed to hear.

I used to allow comments on a blog and lots of people posted trash thinking that they would get a link. I think that they knew nothing of nofollow.

I turned off the comments and now run a bullypulpit instead of a blog.

Just an FYI. This SEO Toolbar for fire fox has an option where it highlights nofollow links. I have found it to be useful.

Ya but that really doesn't help... any blog worth posting in [to get a good comment link] still manages spam...

If the blog in question is about SEO [an example only] you are going to need to waste alot of valuable time writing a solid "non-self-promoting" comment while naturally fitting your link into your comments that still must be "in context" of the threads topic...

Drive by promotional comments:

"Great topic, I don't understand everything you wrote but my domain {url} has more of the same."

...and on to the next blog looking for no nofollow on links...

It still doesn't work... for any website where their links would actually make a link juice difference.

understandable. So it looks like to me, the only reason I would want to comment on someone's blog in the first place is to network or get my name "out there". Not at all for Google or other SE's but for human eyes to say "who's that?" In other words it sounds like what needs to be done if you are going to put a comment on a blog in the first place would be to give a very in depth comment of what that topic is explaining to make people see that you could be an expert in the field and maybe I want to go visit his or her blog by that comment.

Thats the only benefit I see now that I am reading your guys' post.

In other word "don't post on blogs just because you want a link"...

It's nice to try and make [pretend] the comment section was meant as a means to promote yourself... but you will find that most blogs comment sections are merely there to comment on the blog post...

That said - I'm not posting to convince you of anything - just advising the reader of this thread to not expect any real return out of this... there are far easier ways of get links from others...

e.g. in the context of blogs - becoming a contributing blog member is a better approach... links in the actual post is better.

...if of course you're planning on making "in depth comments".
