Since most of the blogs are using Disqus commenting system, So I just wanted to know if the disqus links are valuable for link building? I do about 20 comments a day on disqus blogs but not sure good likes it and i'm wasting my time?
No, it's not. You can place a link on Disqus, but it won't be seen by Google. Like all comment spam, it's useless.
Disqus is a good platform to take part in a conversation and also drop a link. I think it provides a no-follow backlink, but a link from good neighbor is always useful. Believe me folks a link is a link!
Yes diqus comment link is nofollow, but it'll surely help you to target interest users. Continue this technique on your niche blogs.
From what I have heard it is great. Your profile in Dis has a link to your website. So every time you post a comment on a blog you are creating a link to your dis page, which is pointing to your home page. So in reality you should be creating a very powerful link. I read an article on it the other day. If I can find it, then I post it up here for you guys. I cannot remember if it was DoFollow though. Either way I would recommend it because it's best to have a combination of both anyways.
a link is a link, even if google does not give it much weight then you still could benefit from traffic if the site has enough traffic, but of course if the site is like most others, and does not get 2 cents worth of traffic, well, you see where I am going with this....
does commenting on disqus with link hasn't any value to search engines? I heard that it has not seen by search engine because of the Disqus's own mechanism. Can anyone tell me what should i do now?
What I would tell, that any comment posted on dofollow Wordperss blogs is helpful for getting backlinks.
I guess the key question is does disqus use javascript to present the comments or are they embedded in the the html and therefore indexable.
Two points here: 1. Many blogs/sites using Disqus for commenting are set to auto-publish comments and 2. If you write on-topic, useful and meaningful comments (as opposed to spam or spammy-looking ones), there is no reason why at least a good percentage of them would not get approved.
I believe there is a good amount of confusion prevailing on link building so based on my experience (of more than a decade), let me present some thoughts below: 1. no-follow links: People often say: they will not be seen by Google... etc. This is not strictly true. Any kind of link - do-follow, no-follow - can - and will be - noticed by GoogleBot and any other web robot/spider/crawler. The difference is that if the link carries a no-follow attribute, Google will not 'count' that link towards the calculation of the PageRank score of the URL that such a link points to. 2. If a site has a mix of do-follow and no-follow links, its link profile would appear to be much more 'natural' to a search engine and this might lend the site more stability in the long run, across various updates, algo-changes etc.
