Fresh Web Explorer: Will frequent posting of relevant links to own content in comments of blogs and articles hurt rankings?

[lcourse]

Fresh Web Explorer finds daily about 10 articles/blog posts where I could post in comment section a relevant link to content on my own website, which I really belief may be of interest to many readers of the articles.

I would like to do this for the traffic that these links are generating to my site (intention is not ranking improvement).
Would I need to be concerned that it could affect negatively my ranking if I post so many times links to my own site in the comment sections and also considering that I would always link to the same about 5 landing pages on my site?

To give some context. The site for wich I want to build links for is long established PageRank 6  site with legit links from about 1000 different root domains. I would only post to articles published within last 48h.

Would I need to be concerned about the frequency of the posting and if so, any ideas what may be a reasonable frequency to post my links?

If the links are nofollowed automatically by the sites' content management systems, they should effectively be ignored by search engines. That said, search engines most likely at least take into account where your nofollowed links come from, and it won't look good to have a large number of nofollowed links from spammy sources. Of course, these aren't spammy sources.

If the links are followed, they pass PageRank, but can also attract low-quality commenters (who don't care if a post is 48 hours or 48 weeks old). You might leave a good, constructive comment as the 4th comment on a post with a followed link through to your relevant site. Comments one, two and three might also be high quality. However, if the links are not automatically nofollowed by the CMS, spammers can and will end up adding endless comments to the thread with their spam links in the future. This isn't great for your site, as it means you're linked to alongside spam and thus part of a bad link neighbourhood of sorts, despite that not being your intention.

Having a selection of comment links should not hurt the site, but do be wary and very selective about where you post these links. Because comment-based link development was such a heavily-spammed tactic (and still is for some people), you need to be very careful about how you link in this manner, even if it is not for SEO purposes.
