Here's a couple of tips I employ whilst blog commenting. I think it's important to employ these to make your blog commenting more effective. Make a relevant comment - Surely this is common sense, but I can't stress how often I've found a gem - a great high quality blog post, ruined by shitty comments. If you're going to comment to build backlinks, at least contribute something that won't be flagged as spam. Don't reply with 'Thanks for sharing' or 'Nice post'. Trackbacks and Pingbacks - Last week I contacted a blog owner and asked her if she minded me republishing a couple of her articles on my blog with a backlink. Over the past few days, I've acquired three or four Pingbacks to my article. I now have myself some pretty decent backlinks from sites I have no idea about. You can also use Pingbacks to build some backlinks by including a link to an article on your site. The author of the original article may accept the Pingback and give you a nice little backlink after the post. Email Addresses - Don't use a spammy email address. Something like 'email@example.com' is bound to get flagged. Use something more professional, like 'firstname.lastname@example.org'. Even if you have to buy a new domain name, just add a forwarder and create an authentic looking email address. Comment Stucture - Not only do I see a lot of comments containing a junk message, but it seems a lot of people are even too lazy to structure their comment. If the blog doesn't have a URL field, then don't just insert 3 random URLs in your comment - it's inevitably going to get removed. Make it look more professional, IE: Be different - Address a commentor, not the content - Rather than post a shitty sentence about something half-related to the content, read through the comments and find a genuine reply. Either address him (IE: @Mike), or quote his post. Direct a reply to him, and ask him a question regarding his comment. Be sly - This is my personal favourite and it always works. It's especially useful of you're commenting on a .edu blog and don't have the slightest clue about the topic. If the blog includes an external link, leave a comment stating that you're interested in reading more about whatever but the link seems to be down. Most authors/moderators will not even suspect you of spamming, and check the link. Servers crash all the time, and are back up again a few hours later. Post something like this: I can guarantee that the above method is effective. Think outside the box, especially when it comes to high quality .gov and .edu pages. Everybody's competing for some link juice, but if you look different then you can get away with it.
