Ok so I understand that blog posting is a great way to build backlinks (if the blogs are dofollow). My question is how do I post my link in my comment without it looking like spam? Could someone show me an example of a good comment with a link in it?
Links in blog comments are definitely spam, unless the link is genuinely relevant to the comment, and the comment is in turn genuinely relevant to the post you are commenting on. In general, most comments made on blogs simply do not need links. This makes it difficult to include links without looking spammy. For this reason there is really no substitute for having your own blog: in this way you can link to anything you like. The main value in commenting on other people's blogs, apart from networking, is that if you make genuinely interesting and valuable comments, people will naturally want to find out about your blog. They will click on your username and find your blog that way.
Look for blogs with keywordluv installed, these blogs will allow you to post comments with keyworded anchor text to your website. You can find loads of dofollow blogs using dofollow search engines : http://directoryblogger.com/are-you-tired-of-looking-for-dofollow-blogs/ Also look for commentluv enabled blogs (inlineseo's dofollow diver provides a search engine for that), you will be able to get backlinks to your latest blog post. If you don't have a blog or your site doesn't have an RSS you can create a fake RSS - http://www.blogussion.com/blog/promoting-and-advertising/comment-love-static-website to get keyworded backlinks to your internal pages.
Try to post with relevant topic and use keyword with your name or use different keyword ever time , so it looks different and not to be spam.
yes .. while posting comments on blog you need take care about spamming.. you must do not spam.. and its good if your spam links are rejected by moderators.. .because it will hurt u more if spam links are approved . another thing is post relative comments and comments that can be easily approved ..because you must get at least 70-80% comments approved ..other wise it will take longer to get results... sometime you should forgot about no follow and do follow just post comments if blog is good and with high pr.
