Commenting on blogs can be a great tool when building backlinks. One important thing to consider when using blog comments to increase your backlinks is that “nofollow” blogs, while they still do count, do not provide the “link juice” that “dofollow” links do. So if you are planning on using blog comments to boost your backlinks I very strongly recommend sticking to blogs that use the “dofollow” tag for comments. Below I have posted my list of “dofollow” blogs. This list is updated frequently.
