I'm leaving valuable comments on other related blogs. Will this increase my pagerank? Or is there anything other thing than this to do to boost my pagerank? I'm new to SEO please suggest me some tips.
Definitely. but just see that you don't spam. submit your website to blog directories. Try to keep your website refreshing by adding unique content.
You got the point. By default comments on wordpress blogs have the nofollow tag to the links. There are some blogs that don't use plugins to remove the nofollow tag. Yet, if it won't effect on PR doesn't mean that links from comments on blog post are without any value.
mostly high traffic and popular blog use no follow tags, i dont know why but they do. comment only on relevant and new blogs
Thanks, also its only google that implements no follow. Other Search Engines may consider your comments as backlinks, if I'm not mistaken.
If you leave comments on blogs and forums it can hellp your website slighly At least you might get some traffic and if the forum or blog don't have no follow... then you will get some pr.
But if comments are spam then they may be removed and you may lose your black links! So comments should be as much as relevant to the post!
Here I found a list of blogs that follow for comments... http://courtneytuttle.com/blogs-that-follow/
i dont think that will help your seo because most of the blogs are using nofollow on their links to stop comment spam
Most of them thought that putting the comments in the blog will drive traffic to their blogs/sites. But its not much true .Because Most of the blogs are uses the nofollow in their links.So these links are not crawled by search engines. These links present in the comment element of the blogs are not considered as an valid back links.Back links are the main backbone for increasing the traffic linking. But the links present in the comment elements are navigated to the commented member pages But its not crawlable So this will not drive long term traffic. Whenever u adding the links in the comments check for the properties of link.Whether it is crawlable or not.
