A link in the comment itself may or may not be called for. I recommend only including a link of you have a post on your site that ties in nicely. If you do, you can use it to expand your comment. “By the way, I wrote a post on this topic as well over here. My conclusions were X and they seem to contradict yours; what are your thoughts?” If you aren’t able to work in a relevant post, limit your link to in your profile for the comment, where the website field sits.
Wow Brankica! I just don't know how I missed this awesome post :) I have just been going through it for quite sometime and finally bookmarked it for future reference whenever I need it- it is that good! Awesome indeed :) I loved the way you shared all the way you could get traffic and even though I am doing most of these things, there is so-so much more that I need to work on and change the way I look at some others. Thanks so much for sharing, and wishing you the best for the contest :)
Hey Ryan, glad I could help :) I am going to find them later and steal all of them, lol. You had an idea straight away, but some bloggers get stuck and say "I don't have anything to give away". Yes, you do, everyone has something. You can always turn your best posts in different kinds of media, like PDFs, videos, audios, slideshows and just share them everywhere. Thanks so much for the comment!
