Backlinks From The Same Domain - Are They Valuable?

I've got a question pertaining many of the backlinks pointing to my site so if anyone could help me out that would be great

I've got about 400 backlinks to my site, but the majority of them come from maybe 4-5 wordpress blogs. I did some blog commenting a few weeks ago and they're all coming up and being indexed now, but I get a lot of backlinks from other sub-domain pages with a caption like, "Recent Comments."

It's not where I posted the backlink, but it is the same backlink as the comment I posted. So what I'm wondering is am I getting backlink juice from all backlinks even if they're on sub-domains and captions (with my link) pointing to the comment or am I just getting backlink juice from the comments I posted. All backlinks are do-follow by the way.

I know that may be a bit confusing, but I can clarify if need be.

Thanks!

Backlinks will be not be visible in a few days, when new comments will be posted they will move your comment out of recent comment section. And i think its not beneficial at all. I have also got these kind of comments several times and within a week they gets to disappear and its also look spammy.

i agree...may be spce out the psost to other domains

Yeah I was kind of thinking the same thing as you guys, but each day they keep increasing. I'm not sure why and they may be useless, but it's almost like viral backlinks

I'll keep checking daily to see what happens, but I'll start posting on other domains like you said. Thanks!
