Are CPAN (perl modules distributed hosting) links bad?
-
In the past, we contributed to CPAN and have a lot of links from mirror sites as a result. These are legitimate links but I'm wondering if they are holding us back. For those that aren't familiar, CPAN hosts code modules that are freely distributed for Perl programming. The code library is hosted on many mirror sites across the web in an effort to distribute the load of requests for modules when they're installed. The page that exists across multiple sites links a team member's name to our website.
For example, http://cpan.mirrors.uk2.net/authors/00whois.html, http://ukdebian.mirror.anlx.net/CPAN/authors/00whois.html and http://www.mirrorservice.org/sites/cpan.perl.org/CPAN/modules/by-authors/00whois.html. Same content, different website.
Thoughts? Is it worth pursing or disavowing?

Thanks, Andy. They've been around for a long time so I can't say they've created a drop. I'm more or less wondering if they could be holding us back. They show up in SEMRush as having spam scores that vary. I'm going to disavow the ones above 50 and see what happens. Probably not much but we'll see.

If you haven't seen a drop because of this, then it means they are either being ignored by Google, or they are just not worth worrying about. Penguin has evolved and Google are now pretty good at just ignoring links that are 'crappy'.
There might come a point where too many of these does cause you problems though, so if they aren't doing anything either way, perhaps disavow the domain for peace of mind?

Is hiring bloggers to review my products while back linking to my website bad for SEO?
For many months I have been following this strategy of hiring high domain authority bloggers to review my products and link back to my website. For a month or two my rankings improved but now I suddenly lost rankings. Can Google penalize me for hiring bloggers to review my products? Bloggers do mention in the blog that the product was requested for editorial review. Any tips will be helpful. Regards

Link removal
We were hit by penguin and have been going through the process of removing bad links. Things were looking up but then wasa 20% jump in our bad links. They all seem to be related. There are over 100 different domains that all seem to go back to mbiz. examples include http://www.5stone.com.cn/Literature-holders-.html http://www.building-stone.com/Display-furniture.html http://www.china-tombstone.com/Display-exhibition-products-.html It looks like they have automatically gathered data from google to create these pages. I would hope that the guys at Google are clever enough to be aware of these sorts of links. But if not I need to get them removed. I have tried whois but I cant find out how to contact these guys. Has anyone got any bright ideas? Thanks

Clean up bad links or start again?
I am looking to take on a new client but when I looked at their current backlinks they have 420 low quality spammy irrelevant backlinks, all with keyword anchor text and no branded links at all. The site is still ranking well at the moment but I don't expect this to be the case long-term. Would you try and remove the old links and then disavow any that you can't remove or would you start again on a new domain? Not sure which way to play it! Thanks! Karen

If a bad link domain drops from my site do I regain authority.
Hi Guys, I wanted to know for example if 2 years ago I purchased SEO from some guys that were building links to sites that had very high PR which was important way back when. And now those links are negatively affecting my SEO stopping me reaching position 1 for a term 'replacement keys' and we are stuck in position 2. If the sites were to be reset or domains sold for those sites that were linking in do you think this was remove the penalty on us as a knock-on effect. Thanks James

Disavow links
I am working on an account that has had several seo companies
Link Building | | JasperSEO
over the past year so around every corner I discover something new. One the
things I have found are that majority of links to the site is coming from an
outside blog but digging deeper I found that the blog is actually on the same
server as clients. Should I disavow links from that blog or should I leave it
alone?0 -
How might Google differentiate between an artificial link exchange and partners linking to each other?
Hi, All! Artificial link exchanges (contacting a vaguely connected site and requesting to exchange links to increase your PR) is, as far as I know, considered an outdated, not-so-smart technique, as Google might devalue them. Yet, for real business partners to exchange links seems to be an entirely accepted and encouraged technique. While that would be intuitive to a human who's viewing the pages. how might Google detect when two sites that link to each other are linking because they are trusted business associates (valuable) as opposed to when they are doing a link exchange (devalued)? Thanks! Aviva

How to detect which is a bad link ?
Hi.. Our Link Builders at office collects the lists for directories, social bookmarking websites and press releases, article directories. But Im not sure, which all are good links, etc, since I dont get time to check. Is there a way, I can train them to know, which is a bad link, so they can just ignore that link ?
