Need your suggestions: Few of my sites, which have a lot of back links penalized by google, am considering it bcoz of a lot of blog commenting. My sites lost ranking. Kindly suggest is this may be the reason.
I really don't think blog commenting would have got you penalised and suggest you look at other things that may have caused it. If the blogs were do follow and switched to no follow you may have lost all your links.
Google has recently has made slight changes in it's Algo, might be due to that, also timeg is coorect - you should also look at other thing ta may have caused, may be the comments were spamy, may be the owners are not maintaing their blogs and they them selves lost their ranking and so as yours.... may be google did not like your site's back link profile as they only come from blogs. Try variety of back links and regular seo for your site, on page and off page.. I am sure you will surely get it again.
Make sure your back links are diversified. If you ONLY have blog comments linking to your site, search engines may consider that a sign of manipulation or spam. If you have sufficient links from different types of sites, the blog comments are probably not the issue.
Yes, Umesh is right here. It is not blog commenting that dropped your rankings but may be a lack of mixture.
I like Umesh point of view .I suggest you that when you build your site back link then you must remember that your site title is not unique,you are using some variation in your keywords (Like your keywords is Seo company use (top seo company,Best seo company,cheap seo company,affordable seo company).
Google penalize if those were irrelevant links or spamming. Otherwise reason must be some other one. Beside that, do not use black hat. Sometimes Google penalizes and ban the site.
i think if you only do comments like "nice post" etc. well you should expect this to happen, however if you posts a worthy comments considering the blogs that are well maintained plus has a do follow tags there will be no issue
