Update:
This case study is not as good as forum one. I waited to see if the serp will rise after doing 20 nofollow links.
I didnt get any do follow in my industry.
I have seen Google bots crawling my site due to these comments, which is good!
But, my niche is way to competitive for this.
For me, I will say that comments don't work on competitive keywords whereas forum links do work.
Rankings: (homeimprov niche)
Used comment on top5 only.
I honestly think blog commenting would only work on edu/gov sites. if you find some at all.
The thing about scraping is everyone does it and eventually gets juice knocked out
Maybe will try that next.
Oh hell yeah! Can't wait to see the results from this one
@WebMinati
Well the results are out now.
The issues with comments are 1) the spam factor/high OBL, 2) typically no-follow, 3) if your site is seen by Google as relying too much on comments compared to the competition, it may scream unnatural footprint.
You should work around these issues by 1) focusing on blog sections where comments close and the comments are subject to approval (i.e., the moderator function is your friend).2) Pre-check the comments section to ensure the links are do-follow, or else use the no-follow links for direct click-thru or referral traffic, and link diversity. 3) Do enough competition research to know how much commenting you can get away with and still have a natural looking backlink profile.
True that. People should look at your post as it's valuable
hmm interesting will follow
Thanks
Following this one too.
I've commented in a thread before asking the same question that blog comments worked for me. They were done manually by myself and not in spam sites and most of them were no-follow tbh. This was back in 2015 though.
Maybe 2015 was easier

I was not doing SEO at that time.
Just kidding. I think comments still work but I won't waste my time with them
It's working very well for me.
Let me guess, you're in pet niche?
I think sometimes blog comments works, but with manual approval and same niche blogs or similar niches.
But is difficult find a good linkbuilder.
Yup. I did manual approval comments only.
Comment Links are like something that I do when the blog is new to have a name out but if you are someone who doesnt loves to see shitload of backlinks from a single domain then you should skip these.
True! My backlink profile looks a little bulky. Everyone these days love sitewide links though as they are working atm.
I like this journey. Interesting. Will be following along.
Great.
Yup
I started doing blog comments for my new blog yesterday. It will be interesting to see how this goes. I might also share my results here.
Do share.
@WebMinati , any news? I believe that blog comments work for SEO as long as they are manually created and on relevant blogs. How do they work? Well, maybe not so much for link equity (you are likely to get nofollow links anyway) but you will certainly get related traffic (provided you provide meaningful comments). Related traffic might even buy stuff from you, reduce bounce rate (which is somewhat a ranking factor), perhaps, prolong average visit time (which is, I believe, another minor ranking factor), etc ... everything is connected. Same applies to forums too!
I got awesome traffic though, when I did the comments on high ranking blogs.
Visit time is a ranking factor if you're on page 1. That's what I believe but I am wrong all the time. Have to keep testing
blog comments works for me
i comment in some academic blogs like .ac and i see traffic comest at the keyword i used there
Oh awesome. Will try that for sure.
