Does Google Penalize Sites on Comment Spam Blacklists? And Is Your Blog Commenting...

Like others have said, if a site could lose value just through blog commenting, many companies would do this to their competitors. Google knows this, they aren't stupid.

 

No, I just don't think it is fair to blacklist a site for comment spamming, because it could also be done by a competitor. What is more important is the site accepting the comments. If I were Google, I would penalize sites that have high proportion of junk comments to bad neighborhoods, because the owners never bothered to moderate their own sites.

Penalize the sites linking out, not those getting linked to.

 

not going to happen. people would be putting each other in the poopbin CONSTANTLY.
can they lower the value of bad links, yes...
only worry about what links are on your site and where they are going.

PLUS, some people forget that a lot of blogs have comments as nofollow so they arent leaking juice

 

The question for Google is how many would they accidentally hurt vs. how many spammers would they stop by taking into consideration comment blacklist info. If they can take out a huge amount of spam there's a possibility they will risk hurting the odd small website that has not established enough credibility to be immune.

 

Yes, white hat methods is a must if you’re serious about promoting your site

 

The big G hate spam. Technically if you are using tool, example blog comment demon or something like that to spam the inner pages of blogs using the same comment, example "nice post and thanks for sharing" etc etc, your site may be sandbox.

Getting thousands of backlinks from thousand of blogs in the same day with the same comment = suicide
Getting thousands of backlinks from thousand of blogs in the same day with 1000 unique comments ( must be valuable to readers ) = bingo but you will need a lot of man power in this matter

From my personal point of view, if your site have many backlinks, example 100k, a few hundred spam comments will not harm you. If your site have only 1k backlinks, a few hundred spam comments will definately kill your site. If the big G really count those spam comments for big sites, webmasters can easily use this trick to take down their competitors.

 

It is a worry that if your link is placed on a site that is later penalised, you could find your PR plummet, so be careful where your sites are found (ofcourse somebody maliciously could just go around posting the link of their competitor about, we would assume Google and the other search engines, may have some algorithm to detect this, but you never know)

 

I dont think google penalize websites based on seo efforts that can be manipulate and used to penalize a competitor.
google might just ignore them.

 

I don't think Google is going to penalize that website, they're just going to ignore these links. If Google did penalize a website for having too many blog comments, it would be ridiculously simply for anybody to bring down a competitor's website using this method.

 

It is not the best to get lots of backlink with a short period, people used to spam blog with lots of comment, because it is one of the best way to get free backlink.

 

And it is true. It's really hard to harm old reputable websites, but as for new and weak sites, blog and forum spamming is a really bad way for SEO.

Not all comments are spam. But if your comment is posted on a site where there are so many other spammed comments, it's like a spam marker. Also if your site gets 3 new links every week and then gets 100 new links just in a few days it really looks like spam.

 

comment is differ point then blog, but if that comment will cover repeating of key phrase then might google understand spam.

I think Google will happily use akismet blacklist to fight spamming (by penalizing?).

 

It's time for you guys to grow up. Dont believe everything that the so called "SEO Gurus" tell you
