What are your best methods for commenting on blogs for SEO and Traffic? Would you only comment on blogs that are relevant to your own blogs niche? Maybe you would not comment at all...or only on sites that have decent authority. Maybe you would make sure the sites you are leaving comments on don't have high spam scores etc. Maybe you would only comment on do-follow blogs? Let me know your top methods and things you try to avoid?
I mostly write comments in those blogs which are related to my niche because it is best way to get real and relevant traffic to any website.
In the past Blog commenting was the most popular off-page activity but after Google updates spam comments were penalized. If the blog is relevant to your niche and your comment add value to the reader then it can be beneficial otherwise it won't benefit your site.
In 2016, it is advised to comment only on blogs related to your niche. Don't try to stuff keywords in your anchor text. Just use your real name or pen name and take time to write a comment that will add value to the discussion. Do not comment on blogs which have hundreds of spam comments (high OBL). You should not bother about whether the links you get are nofollow or dofollow. Just keep your link profile natural.
It is very important that you work on websites with good page rank associated to your niche. Make sire that you leave interesting comments that can help the community.
don't post only very good idea, very good post/article, etc. post comment in about discussion of the post topic that's it.
Comment on the blogs that suits your niche and use genuine comments so that the moderator can approve your comment.
