Hello, From last 2 weeks I am doing directory submission (free submission) for my website. The sites to which I have submitted my link details are all mirror sites and even my link is approved in those mirror sites. But I doubt whether submitting link details in mirror sites is beneficial ? Please help and advice. Thanks in advance. Regards,
Is it those groups of .info directories that you have been submitting to, all looking more or less the same?
If I understand you correctly, by "mirror" you are likely referring to these directories that mirror / duplicate listings in one directory to countless others? If so, they are of absolutely no benefit but rather can be detrimental to your site. There are a lot of unscrupulous directory owners that do this to populate tons of directories that they then turn around and sell to someone else. If you think Google and other SE's hate directories for other reasons, imagine what they do not like about people getting tons of links in from duplicate databases/directories. I know you cannot control links in, and with that in mind that should not be penal to you. However, what is penal is the lack of incoming links from those directories once they are deindexed and banned from Google. If that makes sense.
You probably will not get much SEO benefit from these mirror sites as they will be considered as duplicates but Google most likely won't penalise your site for it.
