I have started a tech blog in first week of December 2011 and i am commenting on 5 high page rank blogs will these work as good back links and i will get my pages indexed more quickly.
yes, it may not be of much value regarding your rankings, but it will sure help your pages get indexed faster.
You will probably need to create way more than simply 5 links. And if you mean you are placing multiple comments on only 5 blogs, well that's fine - but you need to diversify the number of domains your links are coming from.
I should think that having backlinks that are not broken of course, would be of greater value for the purpose you inquired about.
Posting on 5 blogs means that i only post 5 comments daily as my domain is fresh almost one and half month old. I use different blogs and website for comment posting. Kindly guide me how can i get blog roll.
A blogroll is a list of links to blogs that the blogger likes. A blogroll is usually included in the blog's sidebar. Some bloggers divide their blogrolls into categories. For example, a blogger who writes about cars could divide his blogroll up into categories for links to other blogs he writes, other blogs about cars and other blogs he likes about unrelated topics. The blogroll can be set up based on each blogger's personal preferences, and it can be updated at any time. It's an unwritten rule in the blogosphere that if a blogger puts a link to your blog in his or her blogroll, you should reciprocate and add that blog's link in your own blogroll. Of course, each blogger approaches this with their own blogging goals in mind. Sometimes you may not like a blog that links to you through its blogroll. There are many reasons why you may decide not to reciprocate a blogroll link, but it's good blogging etiquette to at least review each blog that links to you through its blogroll to determine if you'd like to add that blog to your own blogroll or not. Blogrolls are great traffic driving tools. With each blogroll that your blog is listed on comes the possibility that readers of that blog will click on your link and visit your blog. Blogrolls equate to publicity and exposure across the blogosphere. Additionally, blogs with many incoming links (particularly those from high quality blogs as rated by Google page rank or Technorati authority), are usually ranked higher by search engines, which can bring additional traffic to your blog.
You should diversify your links. Having only certain number of links would limit your exposure. Blog comments may be no follow. So you will have to do your research before you waste your time commenting on the blogs. Article directories, press releases, link directories and link exchanges work well too.
well: 1 comments are not treated same as contextual backlinks 2 can be deleted and are deleted pretty often
Have variations with your link building efforts. Don't stick to only 5 blogs, google doesn't give value to all of your posted link on those blogs.
